Replace The Bios Chip In A Thinkcentre A54

Replace the BIOS chip in your ThinkCentre computer.

The ThinkCentre A54 is part of Lenovo's large family of desktop computers. Your Lenovo ThinkCentre's Basic Input/Output System (BIOS) chip is a small, black chip that connects directly to your motherboard. It is a memory chip that stores very basic software that controls all of your computer's hardware. Since the chip is directly attached to the motherboard, you must partially dismantle the computer to replace it.


1. Put on an anti-static wrist strap. Shut down the computer through the Start menu. Unplug the power cable and any other external devices. Rotate the computer tower so the rear panel is facing you. Remove the two Phillips-head thumb screws fastening the right-side access panel to the tower. Remove the side panel to reveal the inside of the computer. Lay the computer tower horizontally on its left side. Touch an unpainted metal surface to discharge static electricity from your body.

2. Locate the small, black rectangular chip on the motherboard. It will have 16 pins on each side. Grasp the chip with a PLCC removal tool, a large-frame tool that resembles a pair of tweezers. It has small hooks that allow you to grasp delicate chips without making contact with the motherboard. Carefully pry the BIOS chip out of the motherboard.

3. Place the new BIOS chip inside the ThinkCentre computer. Align the 32 pins on the new chip with the pinholes in the empty BIOS slot on the motherboard. Carefully but firmly press down on the chip's surface until it is fully connected to the motherboard.

4. Replace the side access panel and its retaining screws. Replace the computer tower to its vertical position, and reconnect all cables.
