3.5.1 CPU Installation
1. Locate the P4 Socket 423 and
open it by pulling the lever gen-
tly sideways away from the
socket. Then lift the lever up-
wards. The socket lever must be
fully opened (90 to 100 degrees).
2. Insert the CPU with the correct
orientation. The gold arrow of
the CPU must be oriented to-
ward the outer corner of the
socket base nearest to the tip of
the lever handle.
3. Once completely inserted, press the CPU firmly and close the socket
lever until it snaps into its locked position.
CAUTION! The CPU fits in one orientation and should drop easily into
place. Do not force the CPU into the socket to avoid bending the pins. If
the CPU does not fit, check its alignment and look for bent pins.
