Power And The Batteries - Toshiba Satellite A55 User Manual

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.

Power and the batteries

Your computer receives its power through the AC adapter and
power cable or from the system batteries (main battery and
real-time clock (RTC) battery). Power problems are
interrelated. For example, a faulty AC adapter or power cable
will neither power the computer nor recharge the batteries.
These are some typical problems and recommended
solutions:
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 a live electrical outlet and the computer.
If the AC power light still does not come on, check that the
electrical outlet is working properly by plugging in a lamp or
other appliance.
The AC adapter and power cable work correctly, but the
battery will not charge.
The battery does not charge while the computer is consuming
full power. Try turning off the computer.
The main battery may not be inserted correctly in the
computer. Turn off the computer, remove the battery, clean
the contacts with a soft dry cloth (if necessary) and replace
the battery.
TECHNICAL NOTE: You must have a least one memory
module installed for the computer to work.
