Locate Phoenix BIOS Passwords
The basic input/output system, or BIOS, is a program that acts as a digital liaison, managing communications between peripherals and the operating system.
Because the BIOS is critical to the operation of a PC, some computer manufacturers and workplaces employ a password for security.
If the password is lost or has been reset through electrostatic discharge, it would be impossible to guess without the aid of computer forensics.
Sometimes you can gain access to the BIOS through the keyboard, depending on the computer, but typically the solution is mechanical.
Contact your computer manufacturer.
All computer manufacturers have websites with technical support available.
Have your computer model number and serial number ready.
If the manufacturer is unable to help locate a password, standard back-door passwords may help.
So-called back-door passwords may help you access the BIOS.
Try using the following back-door passwords to access the BIOS: phoenix, PHOENIX, CMOS, BIOS. BIOS passwords are case sensitive.
Contact the motherboard's manufacturer if the back-door passwords failed.
Find the motherboard's website for technical support.
You will need to open the computer case if you do not know the motherboard brand.
Electrostatic discharge can reset a BIOS password.
Shutdown and unplug the computer.
Unplug the monitor and all peripherals from the PC, including speakers and USB devices.
Ground yourself by wearing an antistatic wristband clipped to the metal case, or touch something metal before you open the case.
Use the screwdriver to loosen and remove the screws from the case. Look for the motherboard, the largest circuit board inside, attached to one side of the case.
Printing on a motherboard can be hard to see without a magnifying glass.
Examine the motherboard for a brand name.
A good place to start searching is near the processor, the large square box on the motherboard. A flashlight and magnifying glass are especially useful for a clear view of the motherboard.
The brand name could be printed anywhere or, sometimes, not at all.
The motherboard battery is round and fairly flat.
Locate the CMOS battery while you have the case open.
If contacting the motherboard manufacturer failed, you will have to remove the battery.
The battery is circular, about the size of a dime, but as thick as two to three stacked dimes.
Do not disconnect or remove anything yet.
Removing the CMOS Battery
Note the location of any cables that need to be disconnected.
Use the digital camera to take pictures of the motherboard, or sketch the location of cables and connectors.
f any components or cables need to be moved or unplugged to reach the battery, you want to remember their exact location.
Leave the battery out for at least 20 minutes.
Remove the CMOS battery carefully so as not to snap or break the clamps.
Leave the battery out for 20 to 25 minutes to allow the capacitors to completely discharge any memory. Avoid touching anything else in the computer.
Tighten the case screws when done.
Return the battery to the motherboard, and reconnect any cables that were disconnected in the case. Close the computer case and tighten the screws.
Look for the setup message on the monitor.
Turn on the computer and closely watch the monitor for the "Entering Setup" message that appears before Windows starts.
The message will tell you which key to press to enter the BIOS setup.
You may need to reboot a few times to see the message, as it appears on the screen for just a few seconds.
Carefully read the settings information on the monitor.
Follow the directions on the monitor for changing the date, boot sequence, and any other settings.
Work slowly and read the screen directions thoroughly.
Be alert and cautious.
Once the settings are saved, the system will start, and the password will have been removed.

Recover Phoenix BIOS
Although most people think the operating system is the core software required for a computer to run, without the computer's BIOS, then the operating system cannot even launch.
When a BIOS installation encounters a problem, it can cause components of the computer not to function correctly or it can cause the computer itself not to function at all.
It is possible to recover the BIOS of a computer, if you know what sort of BIOS the computer's motherboard uses.
The recovery process should take approximately 5 to 10 minutes, during which your computer will seem mostly unresponsive.
Download a crisis recovery program designed specifically to restore damaged or otherwise non-functioning copies of Phoenix BIOS.
Read the instructions for using the recovery program to make sure that no specific changes or configurations need to be done to it before it is used.
Place the Phoenix BIOS recovery program and its files onto a blank disc or a USB drive according to the program's instructions (this usually simply consists of extracting the files from an archive.)
Once the program and its files are in place, insert the disc into the computer's drive or plug the USB drive into an available USB port.
Hold down both the Windows key and the "B" key on your keyboard and press the power button on the computer.
(On some laptop computers, you will need to press the "Fn-B" keys instead.)
Wait for the disc drive light or the USB drive access light to start flickering to show that the computer is accessing the Phoenix BIOS recovery program, and then release the keys.
Wait patiently while the Phoenix BIOS recovery program overwrites the damaged sections of the motherboard's current BIOS installation.
Depending on the computer and the recovery program used, the computer may or may not reboot once BIOS recovery is complete.
If the computer does not reboot on its own, wait at least 10 minutes before manually restarting the computer to make sure that you do not interrupt BIOS recovery.
Eject the disc or remove the USB drive before rebooting to prevent accidentally reloading the recovery program.
Reboot the computer and watch to make sure the Phoenix BIOS screen appears as normal. Once the BIOS loads properly, your operating system should launch as normal.
