154 If Something Goes Wrong Resolving a hardware conflict Memory module problems Incorrectly connected or faulty memory modules may cause errors that seem to be device-related. It is worthwhile checking for these first: 1 Turn off the computer via the Start menu. 2 Remove the memory module. 3 Reinstall the memory module, following the instructions in "Using the computer for the first time" on page 53, and making sure it 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. NOTE Toshiba recommends using only memory modules approved by Toshiba. Power and the batteries Your computer receives its power through the AC adapter and power cable or from the system batteries (main battery and optional secondary 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: The AC power light does not come on when you plug in the AC adapter and power cable. Make sure the AC adapter and power cable are firmly plugged into both the wall outlet and the computer.
