If Something Goes Wrong

Resolving a hardware conflict

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, Turn off computer.

2Click Turn Off.

The operating system shuts down and turns off the computer automatically.

3Remove the memory module, following the instructions in “Removing a memory module” on page 58.

4Reinstall the memory module, following the instructions in “Installing a memory module” on page 53, and making sure the module 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.

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 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.
