13. Replace the microprocessor securing clip.
Orient the clip as shown in Figure 8-12, and hook the
unfolded end of the clip over the tab on the edge of
the socket facing the front of the computer. Then
press down on the folded end of the clip to snap the
clip over the tab on the back of the socket.
14. Replace the support panel.
Align the panel so that the two tabs are to the left. Fit
the tabs into the two slots in the chassis back and
swing the panel closed. Replace the two screws
removed in step 2.
15. Replace the left computer cover.
16. Reconnect your computer and peripherals to
their power sources, and turn them on.
As the system boots, it detects the presence of the
new microprocessor and automatically changes the
system configuration information in the system setup
program.
17. Press <F1> to enter the system setup program, and
check that the Slot 1: Processor 1, Slot 1: Proces-
sor 2, Slot 2: Processor 1, and Slot 2: Processor 2
categories in the Advanced menu match the new
system configuration.
See Chapter 4, “Using the System Setup Program,”
in the system User’s Guide for instructions.
18. Run the system diagnostics to verify that the new
microprocessor is operating correctly.
See Chapter 5, “Running the System Diagnostics,”
for information.
R
eplacing the RTC Chip
The RTC chip has a built-in lithium battery that main-
tains system configuration, date, and time information in
a special section of memory when the system is turned
off.
The built-in battery can power the RTC chip for up to
10 years without a power source; the actual operating life
of the battery depends on how the system is used (for
example, if the system is on most of the time, the battery
gets little use and thus lasts longer).
To determine if the RTC chip needs replacing, reenter the
time and date through the system setup program. Turn off
the system for a few hours, and then turn it on again.
Enter the system setup program. If the date and time are
not correct in the system setup program, replace the RTC
chip.
NOTES: Some software may cause the system time to
speed up or slow down. If the system seems to operate
normally except for the time kept in the system setup pro-
gram, the problem may be caused by software rather than
by a defective RTC chip.
The system can be operated without a RTC chip; how-
ever, the system configuration information maintained by
