Check the battery status light— If the battery status light flashes orange
or is a steady orange, the battery charge is low or depleted. Connect the
computer to an electrical outlet.
If the battery status light flashes green and orange, the battery is too hot
to charge. Turn off the computer, disconnect the computer from the
electrical outlet, and then let the battery and computer cool to room
temperature.
If the battery status light rapidly flashes orange, the battery may be
defective. Contact Dell (see "Contacting Dell" in the Dell™ Owner's Manual
that came with your computer).
Test the electrical outlet— Ensure that the electrical outlet is working by
testing it with another device, such as a lamp.
Check the AC adapter— Check the AC adapter cable connections. If the
AC adapter has a light, ensure that the light is on.
Connect the computer directly to an electrical outlet— Bypass power
protection devices, power strips, and the extension cable to verify that the
computer turns on.
Eliminate possible interference— Turn off nearby fans, fluorescent
lights, halogen lamps, or other appliances.
Adjust the Power Properties— See the Tell Me How help file or search
for the keyword standby in the Help and Support Center. To access the help
file, see "
Accessing Help."
Reseat the memory modules— If the computer power light turns on but
the display remains blank, reseat the memory modules.
Ensuring Sufficient Power for Your Computer
Your computer’s Intel® Mobile Pentium®4 microprocessor requires more power than
the microprocessors used in Dell’s earlier portable computers. Your computer is
designed to use the 90-W AC adapter and the 4400-mAh battery that shipped with it;
for optimum system performance, you should always use these components.
The 70-W AC adapters used in some of Dell’s earlier portable computers can be used
with your computer, but they will decrease system performance. Likewise, you can
use the 3800-mAh and 3600-mAh batteries from earlier Dell computers, but these
lesser-capacity batteries will discharge faster. Using less-powerful AC adapters or
