Memory problems
Incorrectly connected or faulty memory modules may cause
errors that seem to be device-related. It is worthwhile
checking for these first:
1 Click Start, Turn off computer.
2 Click Turn Off.
The operating system shuts down and turns off the
computer automatically.
3 Remove the memory module, following the instructions
in “Removing a memory module” on page 60.
4 Reinstall the memory module, following the instructions
in “Installing a memory module” on page 55, and making
sure the module is seated properly.
5 Check for the error again.
6 If 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.
TECHNICAL NOTE: You must have at 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 cord/cable or from the system batteries (battery,
optional high-capacity battery and real-time clock (RTC)
battery). Power problems are interrelated. For example, a
faulty AC adapter or power cord/cable will neither power the
computer nor recharge the batteries.
