Ensuring Sufficient Power for Your Computer
Your computer’s Intel ® Mobile Pentium ® 4 microprocessor requires more
power than the microprocessors used in Dell’s previous 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 older 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 older
Dell computers, but these lesser-capacity batteries will discharge faster.
Using less-powerful AC adapters or batteries may cause you to receive a
WARNING or a SYSTEM CONFIGURATION ERROR message similar to the
following:
WARNING: 70 Watt AC adapter detected. System will not be
capable of running in full performance without a 90 Watt AC
adapter.
T ES T T H E E LEC T RI CA L O UT LET — Ensure that the electrical outlet is
working by testing it with another device, such as a lamp.

the AC adapter has a light, ensure that the light is on.

search for the keyword standby in the Help and Support Center. To access help,
see page 72.
R ES E AT T H E M EM OR Y MO DU LE S — If the computer power light turns on
but the display remains blank, reseat the memory modules (see page 105).
