As the battery charges, does the green battery
indicator light up?
Yes. Go to step 9.
No. Go to step 7.
7.
Is the battery indicator flashing green and
amber?
Yes. Your computer may be in a hot environment.
Charging the battery in this condition may affect the
life span of the battery. Continue to step 8.
No. The problem is resolved.
8.
Disconnect the computer from AC power. Is the
the battery indicator still flashing amber?
Yes. You may have a defective battery. Continue to
step 9.
No. The problem is resolved.
9.
Remove the battery, and press its test button. Is
the uppermost indicator in the charge gauge of
the battery flashing?
Yes. You have a defective battery. Continue to step 9.
No. The problem is resolved.
10. If a spare battery is available, fully charge it, and
then install it in the computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective. Call Dell for a
replacement. (See Chapter 5, “Getting Help,” for
instructions.)
No. Call Dell for technical assistance. (See Chap-
ter 5, “Getting Help,” for instructions.)
No Power to a Part of the Computer
If the power indicator shows that your computer is
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
Checklist found in Chapter 5 and fill it out as you com-
plete the following procedure.
1.
Turn off the computer and peripherals, and dis-
connect them from AC power. Disconnect any
attached peripherals from the computer.
2.
Make sure that the AC adapter is connected to
the computer and to AC power, or confirm that a
fully charged battery is properly seated in its
compartment.
3.
Turn on the computer. Is the display on?
Allow one minute for the computer to initialize its
components before checking for signs of power.
Yes. The entire computer is receiving power; the
problem is resolved.
No. Adjust the brightness of the display. If the dis-
play still does not show an image, continue to step 4.
4.
Turn off the computer, and reseat (remove and
reinstall) any installed memory modules.
To remove a memory module, carefully spread apart
the inner metal tabs of the memory module socket just
far enough for the memory module to disengage from
the socket (the module should pop up slightly). Then lift
the memory module away from the socket.
To reinstall a memory module, align the memory
module’s edge connector with the slot in the center
of the memory module socket. Press the memory
module’s edge connector firmly into the socket.
Pivot the memory module down until it clicks into
place. If you do not hear a sharp click, remove the
memory module and reinstall it.
NOTE: Memory modules are keyed, or designed, to
fit into their sockets in only one direction. The sock-
ets on the system board are notched so that the
memory module can be firmly seated only one way.
5.
Turn on the computer. Is the display on?
Yes. The entire computer is receiving power; the
problem is resolved.
No. The display may be defective. See “Trouble-
shooting the Built-In Display” found later in this
section. If the display still does not work, connect an
external monitor and run the Dell Diagnostics. (See
Chapter 4, “Running the Dell Diagnostics,” for
instructions.) If you cannot isolate the problem after
running the diagnostics, call Dell for technical assis-
tance. (See Chapter 5, “Getting Help,” for
instructions.)
