Replacing the processor

Your system board currently supports the Intel Celeron and Pentium III (FC-PGA 370) processors. See the Gateway Web site at www.gateway.com for updates on processor speeds supported by your system.

When replacing a processor, order a processor upgrade kit. The kit includes the processor and a heat sink..

Warning It is critical that a heat sink be installed on the processor to provide sufficient cooling.

To replace the processor:

1Turn off the computer, disconnect the power cord, and disconnect the modem cord, if your computer has a modem.

2Open the case by following the instructions on page 19, observing the static electricity precautions on page 17.

3Remove the heat sink:

aDisconnect the fan cable from the fan connector on the system board. (See “System board” on page 7 for the location of the fan connector.)

bThe heat sink is attached to the processor socket by a metal clip. Unhook the clip from the tab on the processor socket by pressing down on the clip and then pulling out on the clip.
