Total Power Failure When Using the Bat-
tery
If an AC adapter is not connected to your computer, the
computer’s power source is its battery. If the power indi-
cator does not light up when you turn on the computer,
the battery’s charge may be depleted. If the low-battery
indicator and the charging indicator are both flashing, the
battery may be defective. To troubleshoot this problem,
make a copy of the Diagnostics Checklist found in Chap-
ter 5 and fill it out as you complete the following
procedure.
NOTE: Before you begin this procedure, make sure that
the
SYSTEM SWITCH option in the System Setup program is
set to ON/OFF . For instructions, see “Using the System Setup
Program” in Chapter 2.
1. Turn off the computer and peripherals, and dis-
connect them from AC power.
2. Reseat the battery by removing it from the bat-
tery compartment and then replacing the battery
in its compartment.
3. Turn on the computer, and hold the power switch
in the ON position for 10 seconds. Do the indica-
tors light up?
Allow one minute for the computer to initialize its
components before checking for signs of power.
Yes. Continue to step 4.
No. Use the AC adapter to connect your computer to
AC power. If the computer operates normally
when using AC power, go to step 7. If the computer
does not boot when using the AC adapter, see the
previous subsection, “Total Power Failure When
Using the AC Adapter.”
4. Is the low-battery indicator flashing?
Yes. Continue to step 5.
No. The problem is resolved.

then install it in the computer.
10. Turn on the computer. Is the power indicator on
and the low-battery indicator off?

technical assistance. (See Chapter 5, “Getting Help,”
for instructions.)
No. Call Dell for technical assistance. (See Chap-
ter 5, “Getting Help,” for instructions.)

receiving power, but the display remains blank, part of
your computer is probably not receiving power. To trou-
bleshoot this problem, make a copy of the Diagnostics
