Incorrectly connected or faulty memory modules may cause errors 
that seem to be device-related. It is worthwhile checking for these 
first:

Click Start, and then click the arrow next to the Lock button in 
the lower-right part of the Start menu.

The Shut Down menu appears.

Click Shut down.

The computer shuts down completely.

Remove the memory module, following the instructions in 

Reinstall the memory module, following the instructions in 

, and making sure the 

module is seated properly.

Check for the error again.

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.

For this model, Slot A is the bottom slot. Slot B is the top slot. If only 
one memory module is to be installed, it must be installed in Slot A.

TECHNICAL NOTE: You must have at least one memory module 
installed for the computer to work.

Your computer receives its power through the AC adaptor 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 adaptor or 
power cord/cable will neither power the computer nor recharge the 
batteries.

Here are some typical problems and how to solve them:
