Troubleshooting Your Computer 3-19
9. Reinstall any diskette, hard-disk drive, or
PC Cards that you removed in step 3.
10. Replace the battery.
11. Reconnect your computer and peripherals to AC
power, and turn them on.
12. Does the computer work properly?
Yes. The problem is resolved.
No. If the computer is able to boot, run the Dell diag-
nostics to identify computer damage. (See Chapter 4,
“Running the Dell Diagnostics,” for instructions.) If
the computer is unable to boot, see “Troubleshooting
a Power Failure” found later in this section. If you
cannot identify the damaged component(s), call Dell
for technical assistance. (For instructions, see Chap-
ter 5, “Getting Help.”)
Troubleshooting a Damaged Computer
If your computer is dropped or damaged, use the follow-
ing 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 your computer, and disconnect it from
the AC adapter. Then disconnect the AC adapter
from AC power. Turn off any attached peripher-
als, and disconnect them from their power
sources and then from the computer.
2. Save all your work, exit any open application pro-
grams, and remove the battery.
3. Open the I/O panel door, and ground yourself by
touching the unpainted metal surface of the I/O
panel.
4. Remove the options cover from the bottom of the
computer. Remove and reinstall any memory
modules in the memory module sockets, and then
replace the options cover.
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. Verify that any installed PC Cards are properly
seated in the PC Card connectors. Verify that the
hard-disk drive is properly installed.
6. Replace the battery.
7. Reconnect your computer and peripherals to AC
power, and turn them on.
8. Run the Dell diagnostics to verify that the computer
is operating properly. (See Chapter 4, “Running the
Dell Diagnostics,” for instructions.)
9. If the computer does not operate properly, make
a copy of the Diagnostics Checklist found in
Chapter 5 and fill it out. Then call Dell for techni-
cal assistance. (For instructions, see Chapter 5,
“Getting Help.”)
Troubleshooting a Power Failure
Occasionally, you may experience a power failure in all
or part of your computer. A total power failure is indi-
cated by the absence of electrical activity (such as lights
and sounds) from the keyboard, display, hard-disk drive,
and diskette drive. In a partial power failure, one or more
of these indicators shows that there is power to a part of
the computer.
To determine if there is any power to the computer, make a
copy of the Diagnostics Checklist found in Chapter 5 and fill
it out as you complete the following procedure.
