Installing System Board Options 6-73. Remove the metal clip that secures the heat sinkto the microprocessor socket. Then remove theheat sink from the microprocessor chip.Press down on the folded part of the clip with a smallscrewdriver to release the clip (see Figure 6-9). Thesecuring clip hooks over tabs on the sides of thesocket.Figure 6-9. Microprocessor Heat Sink4. Remove the microprocessor chip from the socket.Your microprocessor socket is a zero insertion force(ZIF) socket with a lever-type handle that secures thechip in, or releases it from, the socket.To remove the chip, pull the microprocessor-socketrelease lever straight out until the chip is released(see Figure 6-10). Then remove the chip from thesocket. Leave the release lever extended so that thesocket is ready for the new microprocessor.Figure 6-10. Removing the Microprocessor5. Unpack the new microprocessor.If any of the pins on the chip appear to be bent, seethe chapter titled “Getting Help” in your Diagnosticsand Troubleshooting Guide for instructions onobtaining technical assistance.6. Align the pin-1 corner of the microprocessor chip(see Figure 6-11) with the pin-1 corner of themicroprocessor socket (see Figure 6-12).NOTE: Identifying the pin-1 corners is critical topositioning the chip correctly.CAUTION: Be careful not to bend any of thepins when removing the microprocessor chipfrom its socket. Bending the pins can perma-nently damage the microprocessor chip.press here to releasesecuring clipsecuring clipCAUTION: Ground yourself by touching anunpainted metal surface on the back of thecomputer.CAUTION: Be careful not to bend any of thepins when unpacking the microprocessor.Bending the pins can permanently damage themicroprocessor.microprocessor chipmicroprocessorsocketrelease lever
