Figure 216: Removing the protective socket cover (new system board)
Ê Place your thumb against the front edge of the protective socket cover and
rest your index finger on the rear grip.
V CAUTION!
Be careful not to touch or bend the pins on the processor socket!
I Save the socket cover for future use. Always replace the socket cover
if you remove the processor from the socket.
Ê Use a magnifying glass to inspect the socket spring contacts for damages
from different angles. Do not use the spare system board if any irregularities
are visible. Possible damages:
– Contact spring is bent backwards upon itself
– Contact spring tip position is shifted or out of alignment
V CAUTION!
Never not try to fix bent contact springs. Doing so may result in loss
of electrical performance and reliability.
