If Something Goes Wrong
Memory problems
Memory problems
Incorrectly connected or faulty memory modules may cause errors
that seem to be hardware or even software related. It is worthwhile
checking for these first:
1 Click Start, and then click the Shut down button in the
lower-right corner of the Start menu.
The computer shuts down completely.
2 Remove the memory module, following the instructions in
“Removing a memory module” on page 35.
3 Reinstall the memory module, following the instructions in
“Installing a memory module” on page 30, and making sure the
module is seated properly.
4 Check for the error again.
5 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.
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.
Power and the battery
Your computer receives its power through the AC adaptor and power
cord/cable and from the real-time clock (RTC) battery. A faulty AC
adaptor or power cord/cable will not power the computer.
Here are some typical problems and how to solve them:
The ON/OFF light does not come on when you plug in the AC
adaptor and power cord/cable.
Make sure the AC adaptor and power cord/cable are firmly plugged
into both the wall outlet and the computer.
If the ON/OFF light still does not come on, check that the wall
outlet is working properly by plugging in a lamp or other appliance.
