Memory problems
Incorrectly connected or faulty memory modules may cause errors
that seem to be device-related. It is worthwhile checking for these
first:
1Click Start, then click Turn off computer.
2Click Turn Of f.
The operating system shuts down and turns off the
computer automatically.
3Remove the memory module.
4Reinstall the memory module, following the instructions in
“Adding memory” on page54, and making sure it is seated
properly.
5Check for the error again.
6If the error recurs, remove the memory module entirely and
check for the error again.
If removing the memory module eliminates the error, the
memory module may be faulty. If the error recurs without
the memory module installed, the error is not caused by
the memory module.
TECHICAL NOTE: You must have a least one memory
module installed for the computer to work.
Power and the batteries
Your computer receives its power through the AC adapter and
power cable or from the system batteries (main battery and real-
time clock (RTC) battery). Power problems are interrelated. For
example, a faulty AC adapter or power cable will neither power
the computer nor recharge the batteries.
Here are some typical problems and how to solve them:
