Replacing the Processor Chip

If you need to remove the existing microprocessor chip to replace it with a math coprocessor or OverDrive chip, follow these steps:

1.Use the illustration on page 4-3 to locate the processor socket on the system board.

Make sure you ground yourself by touching the metal surface on the inside of the computer’s back panel before you touch the processor chip. Then remain as stationary as possible while you install it. Do not touch the pins on the processor chip. Handle the processor only by the edges of its case.

2.If you use a chip puller, position the puller between the processor chip and the socket.

You can also use a small, flat-edged screwdriver instead of a chip puller. Carefully wedge the tip of the screwdriver between the processor chip and the socket. Gently turn the screwdriver until the chip begins to separate from the socket. Move the screwdriver to another side of the processor chip and again turn it until the chip separates from the socket. Keep doing this until you can lift the processor chip straight up from the socket.

3.Gently pull the processsor chip straight up and set it aside.

4.Remove the replacement chip from its package and inspect the pins. If they are bent, do not install the processor chip. Return the chip to the place of purchase and ask for a replacement.
