Type Speed ​​Internet Access

Type Speed ​​Internet Access - Access speed will depend on the network technology around the distance and distance / environmental conditions when the internet connection is made. The development of information and communication technology today allows us to connecting computer to the Internet in some way. There are several types of options / type internet speeds that can be used. Here is the internet speed in accordance with the selected channel. Dial-Up connection (via the PSTN Line) Before there were mobile, communication is generally done through telephone lines. We can access the Internet by connecting the computer to the home telephone wiring via analog modem (conventional). This method is often referred to as a dial up connection. Dial-up via the PSTN (Public Switched Telephone Network) is the way we connect to the ISP (Internet Service Provider) via the regular telephone network (PSTN), for example, is "Instant Telkomnet" from ISP Telkom. ADSL connection ADSL (Asymetric Digital Subscriber Line) is a modem technology that works at a frequency between 34 kHz to 1104 kHz. This is the major cause of data transfer speed difference between an ADSL modem with a conventional modem (that works at frequencies below 4 kHz). ADSL advantage is to provide the ability to access high-speed internet and voice / fax simultaneously (on the customer side by using a splitter to separate the telephone line and a modem line). What is the maximum bandwidth that is obtained when we use internet access using ADSL: For a 384 kbps line rate, maximum bandwidth obtained close to 337 kbps. For a 384 kbps line rate, average throughput (speed donlod) that can be obtained about 40 Kb / s. For a line rate of 512 kbps, which is obtained close to the maximum bandwidth of 450 kbps. For a 512 kbps line rate, average throughput (speed donlod) that can be obtained about 52 Kb / s. Examples ADSL connection is "Speedy" from Telkom. Compared to dial-up connections, ADSL connections much more rapidly that many are turning to service this connection. GPRS connection In theory GPRS promises speeds ranging from 56 kbps to 115 kbps, allowing Internet access, transmission of multimedia data to a computer, notebook and handheld computers. However, in its implementation, it depends on the following factors: The configuration and allocation of time slots at BTS level Software used Support features and mobile applications used This explains why at certain times and in certain locations GPRS access was slow, even slower than the access CSD which has a speed of 9.6 kbps. 3G connection 3G network is not an upgrade from 2G; 2G operators affiliated with 3GPP need to replace many components to be able to provide 3G services. While the 2G operators that are affiliated with the 3GPP2 technologies easier to upgrade to 3G because of its various network element has been designed for the direction of broadband wireless services (wireless broadband). Telecom mobile phone network has increased towards the use of 3G services from 1999 to 2010. Japan is the first country to introduce 3G nationally and transition to 3G in Japan already achieved in 2006. After Korea became the first adopters of 3G networks and the transition has been accomplished in the early 2004 and lead the world in the field of telecommunications. HSDPA In a crowded office environments users can enjoy streaming video with an estimated speed of 300 Kbps. Excess HSDPA is to reduce delays in downloading the data (delay) and provide faster feedback when the user uses interactive applications such as mobile office or high-speed Internet access for use of the facility to download games or audio and video. Another advantage HSDPA, increase system capacity without requiring additional frequency spectrum. This leads to reduced costs of mobile data services significantly. WiFi Wi-Fi (Wireless Fidelity) is a wireless connection such as mobile phones by using radio technology, so users can transfer data quickly and securely. Wi-Fi not only allows you to access the Internet, Wi-Fi can also be used to create a wireless network in the company. Because of that many people associate Wi-Fi with "Freedom" because Wi-Fi technology gives freedom to users to access the internet or transfer data from the meeting room, hotel room, campus, and cafes are marked "Wi-Fi Hot Spot". Also one of the advantages of Wi-Fi is practicality, no longer need to install the cable network. For the problem of speed depending on the signals obtained. Wireless Broadband Broadband Wireless Access also called still acceptable in a vehicle speed of 60 kilometers per hour. WiBro was developed jointly with Samsung Electronics and Technology Research Institute (ETRI) and has received a certificate from the WiMAX Forum. This technology is able to transmit data at speeds up to 50 Mbps. Data transfer speed is able to outperform the data transfer speed of HSDPA platform that has the ability to send data up to 14 Mbps. LAN Commonly abbreviated Local Area Network LAN is a computer network that the network only covers a small area. Today, most LAN based on the IEEE 802.3 Ethernet technologies using a switch device, which has a data transfer speed of 10, 100, or 1000 Mbit / s. In addition to Ethernet technology, the current 802.11b technology (commonly called Wi-Fi) is also often used to form a LAN. Cable TV In the home network, the cable from the "cable" used coaxial cable and installed a "dividing line" (splitter) cable. After the cable from the network (cable network) past the splitter, cables channeled into two channels, one for TV and one to the cable modem. From the new cable modem to the Ethernet card and then to the computer.

Origins of Computer Viruses

Origins in Computer Virus | This time I will share information about the Origins of Computer Virus. Maybe some of you already know what it komputr virus, but do not know the history or origin, right ?. Well here I will reveal in full to you about the origin of computer ....... Happy reading Origins on Computer Viruses The concept of making the virus was discovered in 1949. At that time, John von Neuman, had thought that there are programs that can replicate itself. This is evidenced by three programmers from AT & T Bell Laboratories who witnessed their creation program fighting for control over the computer in an experiment called "Core Wars'. The most striking evidence is the first virus to be officially recognized (C) Brain not come from America or Europe as the inventor of the computer state, but coming from Pakistan. In 1986 two brothers Basit and Amjad, the owner of a computer store in Lahore, Pakistan, was the first to incorporate a small program in the boot sector on a floppy disk 360 KB which will run automatically when the computer starts. Keep in mind that at that time almost all computers can only be turned on via a floppy disk, only a few are using the hard drive because it was still very expensive and not general. Upon entry into the boot sector, this program will remain in the computer's memory to replicate itself to other floppies inserted into drive A or drive B. A year later, the University of Delaware realized that they had been infected with the virus because of the label '(c) Brain "on floppy disks they use. Once discovered by two brothers Basit and Amjad, the development of increasingly sophisticated viruses. This is evidenced by a programmer called Ralf Burger. In the same year with the discovery of two brothers Basit and Amjad, burgers, be aware that the file can be programmed to conduct automatic coffee by inserting itself into other files. He wrote a sample program called VIRDEM that can infect .COM files Then the sophistication of the virus was also revealed by Fred Cohen of the University of Southern California, who conducted the first doctoral dissertation on the topic of computer viruses. Cohen discovered the fact that once you create a good virus, the impact caused by this virus and its spread would be very unusual, if not unexpected though its creator. Meanwhile, in Tel Aviv, a programmer another experiment with creating the first virus with Suriv name-1, these malicious programs can infect all .COM files After the success, munculah Suriv-2 can infect EXE file, then the third generation of this virus is more advanced because it can infect .COM and .EXE file types. Creation of four that shook the world and is known as the Jerusalem virus, every Friday the 13th of this virus deleting files that run so often known as Friday the 13th. The virus is named after the Jerusalem because it was found at the Hebrew University of Jerusalem by Yisrael Radai. In other parts of the world, a young student at the University of Wellington, New Zealand discovered a very simple technique to make the virus very effectively. Each eight-time boot from an infected floppy disk, it will display the message "Your PC is now Stoned" which also gives the name to the virus, Stoned. The virus is only a few hundred bite, but because of its ability to reproduce itself and replicates Stoned become the most widespread virus in the world in his day. At the beginning of the era of the emergence of viruses, only Stoned, Cascade and Jerusalem are dominating. Meanwhile, in Indonesia known Denzuko, known as the Den Zuk or Ohio (the name given by McAfee since the virus was first discovered in Ohio State University). An Italian programmer creating a virus called Ping Pong. As the name implies, this program displays the bouncing ball on the screen. The virus is quite horrendous, but not had time to spread rapidly because of limitations that only runs on computers 8088 and 8086. Just like Brain, which can infect only 360 KB floppy disks. Other viruses are well known in the early emergence of the virus is Cascade, written by a German programmer. Cascade introduces a new technique, namely encryption complicates repair infected files. This technique also developed by Mark Washburn when writing polymorphic viruses (many forms to complicate identification by antivirus software) first, namely 1260 (Chameleon) or virus Chameleon.

Getting to Know More About Computer Software In

Getting more In About Computer Software | Computer Software is one part other than the hardware. We know that the software is part of the software while the hardware is hardware. If you want to be likened to, you can probably get the sense that the software or the software is a part that can not be held by hand and when you turn integrated with a variety of work using computers. As with the hardware or hardware, these are some of the components that we can grasp and seen by naked eye. Computer Software division You need to know that the computer software is divided into two sub-ie software and application software. A program that allows the hardware in your computer to run properly called the system software. Meanwhile, the software application is a program that gives permission to the user to be able to do anything other than run the hardware. Some other types of software that would be described as follows. Software games Is a software that has the properties of entertaining or entertaintment. Some types of software games that you can find is action, shooting, adventure, and a fairly well-known today is roleplaying. Software drivers An integrated software to some special hardware. Some of this type of software is software that gives orders to printers, scanners, flash, or video cards. Educational software The nature of education is so focused on this type of software. You will gain an understanding as to type, counting, and perform testing subjects. One example is the educational software TOEFL. Software media You can use this type of software when you want to edit video, images, running music, or watching movies. Software productivity One of the most famous software in this case is Microsoft office. A software that is used when we want to type, perform complex calculations, create a slide presentation, to perform editing of the image. Operating system Is a parent software from your computer. Some software in the computer has direct dependence on the operating system. That is, if an operating system has no direct compatibility, the software you want to run your computer can not function.

Computer Technology Future

Computer technologies of the future - Along with the times, and advances in science and technology is so fast, is not impossible for man to enjoy a variety of increasingly sophisticated services and fast as well as computers. Recently, NEC Design Ltd. is an institution in Japan to offer a new concept of computer technology which is very surprising. The concept is Computer Model Pena. This is the model of a computer model of the pen. If seen at a glance secaara is highly unlikely pen called a computer. If it had been aware of the functions and benefits we would definitely be surprised. This computer is called a P-ISM. As explained by the designer NEC as "Pen-style Personal Networking Gadget Package". The computer models estimated at $ 30,000, or about 300an million. The price for the size of a computer may be very expensive, but if viewed in terms terkologi certainly not nothing. According to the NEC Website Design, computer types P-ISM pen computer is package that includes five functions: Mobile stylized pen by means of data input using handwriting virtual keyboard small projector Camera Scanned Personal ID password that serves as the owner's identity P-ISM connected to each other with the adjacent wireless technology. This model can also connect to the internet using mobile phone functions at the P-ISM .. This personal gadget minimalist style pen that has a feature Exceptional Complete. Initially we thought that the model of laptop technology "keyboard and screen" will last long. but we can not deny that pen and paper is stationery and symbols that naturally we receive, only a matter of time until someone finds the latest sophisticated products masquerading as "Smart Pen" or "smart paper". So perhaps shortly laptops (portable computers) will not sell anymore. In addition to NEC Design Ltd., the world's leading computer company Microsoft Corporation also do not want to miss. The new -new Microsoft is developing a prototype of future computers and is being perfected. This computer is named Microsoft Surface. In this technology, is like we have a digital camera and a cellular phone / mobile phone that already has the support wareless, then after we photographed the object / person with a camera before, and then we put the camera on a touchpad or touchscreen monitor that resembles a table. Once placed, then you will see pictures of objects or faces which we have earlier portraits in our screen without moving it. Then, with this technology, the picture can be enlarged, reduced, inverted by hand. And more exciting again. Put a phone was on the table. Slide the monitored image toward the phone. And immediately a picture also has moved to the memory card we hold our cell phones without the cell phone. Two developments in computer technology over the political reality may be a considerable period of time. We certainly have to wait menggunya. But in the near future we will also be treated to the development of computer technology which is no less sophisticated. In the year 2010 will soon be released Laptop new type. Viewed in terms of shape and kecanggihanya, a laptop that will be released this year is really quite fantastic. TriBook with three ultra-wide-screen concept that is 21in wide-screen. It also has an 8x SuperDrive, a 1TB hard drive, and MacBook Pro-caliber CPU, plus a trackpad multitouch keyboard. Future generations of laptops made by German industrial designer Felix Schmidberger, models classy, ​​elegant, futuristic laptop that uses OLED touchscreen. Perhaps more appropriately called Paper PC because of its shape like a sheet of paper in the form of a screen interface and equipped to operate in a manner pen touch screen. Designed by Avery Holleman. A laptop that has two screens with a similar design book, prototype of the XO-2 and One Laptop Per Child (OLPC). Future Technology Some examples include: 1. Intelligent machines Atomic Size, Nanotechnology "Coal and diamonds, sand and computer chips, cancer and healthy tissue: throughout history, variations in the arrangement of atoms have distinguished the cheap from the cherished, the diseased from the healthy. Arranged one way, atoms make up soil, water, and water. Arranged another, they make up ripe strawberries. Arranged one way, they make up homes and fresh air; arranged another, they make up ash and smoke ". Eric Drexler, Engines of CreationNanoteknologi are all future technologies that allow humans to manipulate tiny particles that magnitude almost super-sized atom! Nanometer itself is the size of 1 / semilyar meters, or nearly 50,000 cut hair thickness. That awesomeness nanotechnologies. The goal is to create new materials of the future, even the machines and robots the size of the particles. Materials that will be stronger than diamond, super lightweight, heat resistant and cold with extreme scale, able to conduct electricity better, more durable, environmentally friendly and so on. Application possibilities really devastating and it will change the whole world. Imagine if we could create a variety of new material harder than diamond, and much lighter than steel. (Carbon nanotubes, sp2 bond). We can create super strong framework for cars, airplanes or buildings and bridges. With a lighter weight, all the cars and planes will also be more energy efficient. We can create clothes anti-wrinkle and stain resistant. We also can create bacteria-sized robots, nanobots, and memasukanya into the human body. Functions can be of cure, destroys cancer cells, and even strengthen the human body (Feynman, "Swallowing the Doctor"). Nanobots or even later expected nanoparticles will also be able to re-close the ozone hole. With the nano-sized components, we can create a supercomputer for a matchbox, and a data storage medium which stores millions of gigabytes of information about mankind and the universe, at the tip of the nail. How this technology can be done? Because the super-powerful microscopes that can see the atom has existed since 1981, the Scanning Tunneling Microscope (STM) and Atomic Force Microscope (AFM, 1986). 2. Humans Super Era, Genetic Engineering  "Human genetic engineering has the potential to change human beings' appearance, adaptability, intelligence, character, and behavior. It may be used in creating Potentially more dramatic changes in humans" .Wikipedia Genetic Engineering. Humans have successfully mapped the genes in the giant project "The Human Genome Project". With this data man has map information to explore the function and potential of each gene in the human body. Starting from the genes that determine the physical form of a human, cancer-causing genes, genes that form memories, the genes that create intelligence, even specific genes that regulate the aging process. This will permit the genetic engineering of human beings to create a future that is very superior. Man with perfect health, free from disease, aged more than 100 years and have intelligence approaching genius. Imagine if humans find special gene that makes Einstein's genius. Then the gene could be transferred to all mankind. David Beckham or physical superiority, or even the charisma of John F. Kennedy. But genetic engineering is not just for humans, but also for plants and animals. Genetic engineering can create new types of rice and wheat to harvest many times. We can also create the beef more tender and tasty. We can even create plant and animal consumption with superior nutritional value. 3. Energy terdahsyat throughout the Universe, The Power of the Stars  "What would mean fusion? Endless, cheap energy. Amazing Star Trek, space travel possibilities. Fame, fortune, and Undoubtedly a Nobel or two for the lucky scientist". The Observer, December 2000 Sun, every second, expend energy of all energy used all mankind throughout history. Hydrogen plasma energy giant $ 380 billion-billion Mega-Watt (380 ^ 26 MW), per second. This is the energy which is known as nuclear fusion energy (Nuclear Fusion), the power of the Sun. And the world's scientists are trying to get it. And this is the energy that makes massive stars in the universe burn for billions of years. Terdahsyat energy, throughout the universe. A great experiment is being conducted in the small town of Cadarache in the southern tip of France in a project called ITER. Here Deuterium and Tritium atoms fused with heat reaches 150 million degrees Celsius, nearly 10 times the hot core of the sun. Peleburannya container protected by the tokamak magnetic field so that it does not melt. Remarkably is that deuterium can be produced from ordinary sea water, and Tritium is formed of lithium that can be obtained from natural stone. Terdahsyat energy throughout the universe of water and natural stone. If these scientists successfully created, then the whole world will have a powerful new energy source replacing petroleum. This energy will be so big and efficient, is not limited, very inexpensive, and environmentally friendly. (Note: the use of nanotechnology in photovoltaic solar cells, nanocrystal, is also said to have super huge energy potential that is capable of replacing petroleum). 4. Regeneration Wolverine, Stem Cell Imagine if heart disease and diabetes can be cured completely, the lame can walk, and the blind could see again. You've seen a lizard, which can regrow its tail broken off completely? Or if you're a fan of the comic "X-Men", you must know superhero character named Wolverine. When his body pierced by a knife or a bullet, he can heal the wound with nearly instantaneous. He can regenerate all cells of the body perfectly, instantly. But it was only a fantasy. There is a kind of worm called "planarian worm", which is a lot of life at sea and the river, which was able to grow back even nearly the entire body. Planarians, especially Schmidtea mediterranea species, able to regenerate his body intact, even if staying only a small piece of his body, up to 1/300 part. And when the head dihilangkanpun, he will regrow his head perfectly. What if humans could do that later? If we can directly replace all the cells of our body are damaged perfectly and flawlessly. Scientists have almost reached that magic. Molecular biology technology called Stem Cell, or Stem Cells. This is the most basic cell of the human body, which can be changed, or altered, into any cell or organ in the human body. If you have heart disease, the heart cells can be replaced with stem cells and your heart will function normally again. If you are blind, you retinal cells can be replaced with new cells from stem cells and you will be able to see again. If you are suffering from diseases related to brain function such as stroke, Alzheimer's or Parkinson's, then your brain cells are damaged, even the cerebral cortex of the brain center network, can be replaced by stem cells. And if you suffer from diabetes, the stem cells will save you by regenerating insulin-producing pancreatic cells. 5. Quantum Computer  Imagine a future computer, the speed a thousand times faster than today's fastest supercomputer. Thousands of times faster and more efficiently than IBM "Roadrunner" at Los Alamos that the velocity reaches 1.7 petaflops (1 petaflop = 10 ^ 15 operations per second). This is awesomeness quantum computer. This computer is so powerful because it created a miracle wear phenomena of the quantum world, superposition and Quantum Entanglement. In the example code-breaking (cryptography), to decode the digit to 140, an ordinary computer would take billions of years to solve it. But with a quantum computer, this can be solved in just a few tens of minutes. The man with the computer will also be able to predict the weather on earth and other natural phenomena are very complex to very accurately months in advance, such as earthquakes and tornadoes. And of course this will further revolutionize again the speed of the entire development of advanced technologies that exist today. 6. Harry Potter Robe Disappearing, Metamaterial "The announcement last November of an" invisibility shield, "created by David R. Smith of Duke University and colleagues, inevitably set the media buzzing with talk of HG Wells's Invisible Man and Star Trek's Romulans" .MIT Technology Review Just a few years ago, all the world's leading scientists are still convinced that none of the material in this world that can make people disappear. It really is not possible, because it's against all the laws of nature known to man. But they were all wrong .. Metamaterial, became one of the main ingredients are busy talking. This material could create something, to become invisible. An outfit that use this technology can make the wearer "disappeared", like a magic cloak in the "Harry Potter". A fighter with a metamaterial material will be invisible, not only does not look like a radar technology "Stealth", but totally invisible to the eye as a tool in the Star Trek cloaking device. This can be done for example by creating an artificial material that is able to deflect electromagnetic radiation, as well as light, which is basically electromagnetic radiation. The material can be like tin and plastic are arranged in a particular pattern structure. Metamaterial would bend light around the object that diselimutinya and regroup at the end, like river water around a rock. In a recent study at Perdue University them using special needles that will bend light beyond the shrouded object while the object behind it will be visible. This material is being studied around the world, including MIT, University of California Berkeley, Duke University, and Caltech in LA. 7. Space Elevator, Stairs Towards Stars Space elevator or staircase Space is like a very high lifts from Earth to orbit the Earth in space, 35,000 kilometers high. With this elevator trip to orbit the earth will become easier, and cheaper. Many people hope that the space program which had been stopped up on the moon because it is very expensive, will be started again. And maybe dream of humans to go to Mars, will be realized. Lift was originally just a fantasy, but it turns out the discovery of a new technology, it is becoming very possible to be realized. It is Carbon nanotube technology, new material is said to be stronger than diamond and lighter than steel. This will allow the start of a new era in penjelahajan space. 8. Entering the Era of Hyper-Sonic, scramjet Scramjet will be one of the main transport greatest revolution in the history of the world. The most advanced fighter aircraft in the world today, the F / A-22 Raptor American owned a maximum speed of Mach 2, or 2 times the speed of sound. Scramjet passenger aircraft, will take you to fly at speeds 10 times the speed of sound, Mach 10. Flights from New York to Tokyo are now taken within 18 hours of a long and tiring, will be pursued scramjet, in just 120 minutes. Scramjet does not need to wear regular rocket fuels are expensive and heavy, fuel use liquid hydrogen mixed with oxygen siphoned directly from the atmosphere (air-breathing scramjet engine). Combustion of hydrogen and oxygen at supersonic speed is what will accelerate the speed. This will make flying from one place to another around the world to be super fast. 9. Fountain Of Youth, Resveratrol Maybe later we can find something that allows us to live hundreds of years. But scientists may have found it, something called "Sirtuin", Silent Information Regulator 2 (Sir2) proteins and resveratrol, substances antioxidant that turns are found in red grapes (So often eat grapes.) But scientists have also been create something even more powerful than resveratrol is a drug with the code, SRT1720. "SRT1720 is a thousand times more potent than resveratrol, meaning that it could be taken in smaller doses. A person would have to drink Hundreds of glasses of wine to get the same health benefits from resveratrol. Resveratrol will pretty soon look like ancient technology, "David Sinclair, a biologist at Harvard Medical School 10. Singularity. Someday, there will come a time when all human beings through genetic engineering will have physical and intelligence that was almost perfect. Then with the advancement of computer technology, quantum computing and nanotechnology allows humans to enter Quantum Computer-sized particles into the brain and using nanoparticles to further strengthen his body. This is called Singularity. The unification between human biology with technology. That some of the future development of computer technology which can further facilitate human life. Because I think the primary function of technology is created in order to facilitate human life.

How to Install and Fix CSR Bluetooth Driver

CSR Bluetooth is one of the common Inbuilt Bluetooth devices on most laptop, desktop commonly uses the CSR Bluetooth dongle since most desktop does not have the inbuilt Bluetooth device. What you need to do basically install the drivers CD (that come with it when you buy it) or get the Bluetooth drivers from your notebook/device manufacturer.

This method worked for:
-Windows XP, Vista and Windows 7. Not yet tested with Windows 8.
-CSR and other Bluetooth device.

BLUETOOTH STOPPED WORKING

 BUT, sometimes, even the drivers installed properly, your Bluetooth still does not work. This is the most common problem for CSR Bluetooth devices. The main culprit normally Windows Update. Windows automatically installed a new driver but the truth it is unstable and cause your Bluetooth not working properly. You can also applied the method I described below with other Bluetooth device such as Atheros, Ralink, Broadcom and Realtek. The main reason I make this post specifically for CSR is unlike other Bluetooth devices manufacturer, CSR doesn't seem to have a support site where you can download the stable drivers. So there are 2 ways to solve this:

BEFORE WE START:
1. Make sure to plug in your Bluetooth dongle.
2. For inbuilt bluetooth (commonly for laptop), turn on your bluetooth by pressing the Fn key + Bluetooth key. (look for the bluetooth symbol on your keyboard).

STEP 1: ROLL BACK DRIVERS

click on the picture to enlarge

• Open device manager, look for your Bluetooth Icon,
• Right click on it and select properties
• select drivers tab
• and select roll back drivers,

If the rollback driver options is not available, proceed to STEP 2.

STEP 2: REINSTALL GENERIC BLUETOOTH DRIVER

This method work most of the time especially for those who installed a newer version of the driver (for example the drivers from the windows update). Windows actually have a generic bluetooth drivers which can be use with any bluetooth device. So not to worry if you lost your original driver backup or Drivers CD.

FOR CSR BLUETOOTH
 Open device manager and look for Universal Serial Bus Controller. Click the arrow to expand the list  and you will see CSR BluCore Nanosira listed if you use nanosira Bluetooth.

FOR OTHER BLUETOOTH
Normally for notebook such as ACER, HP and ASUS, or you are using other Bluetooth brand, you will see your Bluetooth listed under Bluetooth or other devices in device manager. you will also see a yellow exclamation mark on it.
(Don't worry if you see too many of them, normally when you install the driver once, all the other will gone - automatically installed).

INSTALLATION

• Right click on the Bluetooth device and select Update Driver Software. 
• Then select Browse my computer for drivers software and then 
• "Let me pick form a list of device drivers on my computer".

Now you will see a Generic Bluetooth radio from the list. Select it and continue with on screen instruction until installation Finish. Sometimes it is listed as Generic BT drivers.

Now you will be able to use your Bluetooth again.

HP Pavilion ZE2000 Windows 7 Drivers

Windows 7 and Pavilion ZE2000

Windows 7 will automatically install the drivers you need. The main problem is you will need to install the graphic driver to get the maximum resolution and performance and also the audio drivers. This is because most ZE2000 uses Intel 82825/82855 GME graphic chipset which no official Windows 7 drivers released by Intel or HP. Further more, all ZE2000 model/variants uses Conexant AC-Link which does have an official support site which provide newer driver for old sound chipset.

ZE2000 Windows 7 Drivers

Actually you only need to use the original Windows XP drivers, but it require a little bit modification before installation.
I already write a brief installation guide to install both audio and graphic drivers.

Audio Driver for Windows 7. : Drivers and installation
Graphic drivers: Drivers and installation

Others Drivers Installation

If you have problems with the other driver do let me know. From my experience you will also need to install Card reader driver (if you want to use it). You can also use your original XP driver, just install it in compatibility mode or use the same audio installation method to install the card reader.

You wifi should work because from my experience windows will automatically installed the driver for it. Do let me know if you have problems with the driver installation.
