Remove Defective BIOS Chip
Step 1
Locate the serial number and system information sticker on the back of the computer. Record the exact and full model number of the computer – not the Pavilion series number.
Step 2
Disconnect the power cord, monitor cable, keyboard cable, mouse cable and any other connected cables or peripherals from the Pavilion computer. Move the computer to a sturdy and flat work surface.

Step 3
Lay the Pavilion computer down on its side so that the left-side access panel is facing upward. Remove the retaining screws or thumb screws on the rear of the Pavilion that secure access panel. Slide the access panel off the side of the computer and set it aside.
Step 4
Locate the BIOS chip on the motherboard. Depending on the model Pavilion computer you own, the motherboard might use one of three different BIOS chips: AMI, Award or Phoenix. In most cases, the BIOS chip is rectangular or square and has a sticker with the BIOS manufacturer name affixed to the top. Take note of the orientation of the chip -- which way the label or logo faces -- so that you know how to install the replacement.
Step 5
Remove the chip from its socket with a chip puller tool if it's shaped like a rectangle. A chip puller tool resembles a small set of tongs you would use for serving food. Position the tong-like points of the chip puller tool on either side of the BIOS chip. Press in on the tool until the points of the chip puller grip the outer edges of the BIOS chip. Pull up gently, but firmly, on the chip until it releases from the socket. Alternatively, use a small flathead screwdriver or awl to pry up the chip gently and remove it.
Step 6
Remove the sticker from the top of the BIOS chip. Scrape away any glue residue from the top of the chip so that you can see the manufacturer of the chip and any model or other number listed. Record all labels and numbers listed on the top of the BIOS chip.
Order and Install New BIOS Chip
Step 1
Go to another computer with an Internet connection and open a Web browser. Navigate to a site that sells replacement BIOS chips for most major manufacturer models. Sites such as BadFlash, BIOSMan and BIOSFlash all provide replacement chips for virtually every desktop computer made and carry a full line of BIOS chips for HP Pavilion computers.
Step 2
Enter your contact and billing details on the website and as much information about your faulty BIOS chip as possible. Enter the full model number of your HP Pavilion and the information you recorded from the top of the defective chip.
Step 3
Select a shipping option for the new BIOS chip, pay for the purchase and complete the transaction. Wait a few days for the site to ship the new BIOS chip to you.
Step 4
Remove the side panel from the HP Pavilion if you replaced it after removing the faulty BIOS chip. Align the new BIOS chip with the socket on the motherboard. Ensure that the label or company logo on top of the chip faces as it did on the old chip.
Step 5
Insert the pins of the chip into the pinholes or slots in the socket. Try to insert them all at once instead of “rocking” or inserting one side first and then the other. After you insert the pins in the holes or slot, press down on the top of the chip gently, but firmly, until fully seated in the socket.
Step 6
Replace the side-panel cover on the HP Pavilion computer. Move the computer back to its installation location and reconnect all the cables and peripherals. Start the computer and wait for it to boot.
Step 7
Press the “Delete” or “F1” key when prompted to enter the system setup utility. Follow the prompts in the system setup utility to load the default BIOS configuration and press “F10” to save the settings and exit. After you save the settings, the computer should boot in to Windows normally.
Things Needed
- Phillips #2 screwdriver
- Antistatic wrist strap
- Awl, chip puller tool or small flathead screwdriver
Warning
- Always use an anti-static wrist strap when working inside your Pavilion computer. The motherboard in the Pavilion computer is very sensitive to damage that may occur because of electrostatic discharge.
