Power Problems

Your computer receives power from the battery which is charged through
the AC adapter. Power problems are interrelated. For example, a faulty
AC adapter or power cable will neither power the computer nor recharge
the battery.
Here are some typical problems and how to solve them:
The DC-IN LED does not come on when you plug in the
AC adapter and power cable
Make sure the AC adapter and attached power cable are plugged into
both a working wall outlet and the computer.
If the DC-IN LED still does not come on, check that the wall 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 doesn't charge while the computer is consuming full power.
Try turning off the computer or shutting down applications such as the
DVD player that use a lot of power.
The 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.
The battery may be too hot or too cold to charge properly. If you think
this is the probable cause, let the battery reach room temperature and try
again.
If the battery has completely discharged, it will not begin charging
immediately. Leave the AC adapter and power cable connected, wait 20
minutes and see whether the battery is charging.
If the battery light is glowing after 20 minutes, let the computer continue
charging the battery for at least another 20 minutes before you turn on the
computer.
If the battery light does not glow after 20 minutes, the battery may have
reached the end of its useful life. Try replacing it.
The battery appears not to power the computer for as
long as it usually does
Check the power options using the TOSHIBA Power Management utility.
Have you added a device, such as a PC Card or memory module, that
takes its power from the battery? Is your software using the hard disk
more? Is the display power set to turn off automatically? Was the battery
fully charged to begin with? All these conditions affect how long the
charge lasts.

Battery Life" in chapter 4.
