C
HECK 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. Shut down 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. See “Contacting Dell” on
page 112.
CHECK THE BATTERY TEMPERATURE — If the battery temperature is below 0° C (32° F), the computer will
not start up.
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 “Power Management Modes” on page 33.
RESEAT THE MEMORY MODULES —
If the computer power light turns on but the display remains blank,
reinstall the memory modules
. See “Memory” on page 88.

The 65-W AC adapters used in other Dell™ portable computers can be used with your computer, but they
will decrease system performance. Using less-powerful AC adapters, including the 65-W AC adapter, will
cause you to receive a
