Installing a Processor
CAUTION
Before installing or removing the processor, make sure that ac power has been removed by
unplugging the power cord from the computer; the standby power LED should not be lit (see
Figure 3 on page 18). Failure to do so could damage the processor and the board.
To install a processor, follow these instructions:
1. Observe the precautions in “Before You Begin” on page 21.
2. Locate the processor socket and raise the socket lever completely.
3. Install the processor so that the corner with the triangle marking (A) is aligned with the corner
where the lever is attached to the socket (see Figure 9).
4. Lower the lever to its original position.
