Troubleshooting Your Computer
3-9
System Flash Codes
When errors that occur during the boot routine cannot be
reported on the built-in display or on an external monitor
(if attached), the Num Lock, Caps Lock, and Scroll Lock
indicators may flash together in a pattern of lights (or
flash code) that identifies the problem. For example, one
flash, followed by a second flash, and then a burst of
three flashes (code 1-1-3) means that the computer was
unable to read the data in nonvolatile random-access
memory (NVRAM). This information is important to the
Dell support staff if you need to call for technical
assistance.
Shutdown failure
A chip on the system board
may be malfunctioning.
Run the System Set test group in the Dell Diagnos-
tics. (For instructions, see Chapter 4, “Running the
Dell Diagnostics.”)
Time-of-day clock
lost power
Data stored in NVRAM has
become corrupted.
Connect your computer to AC power to charge
the battery. If the problem persists, try to restore
the data. To restore the data, press <Fn><F1> to
enter the System Setup program. Then immediately
exit it (as described in “Using the System Setup Pro-
gram” in Chapter 2). If the message reappears, call
Dell for technical assistance. (For instructions, see
Chapter 5, “Getting Help.”)
Time-of-day clock
stopped
The reserve battery that sup-
ports the data stored in
NVRAM may be dead.
Connect your computer to AC power to charge
the battery. If the problem persists, call Dell for
technical assistance. (For instructions, see Chap-
ter 5, “Getting Help.”)
Time-of-day not
set—please run the
System Setup
program
The time or date stored in the
System Setup program does not
match the system clock.
Correct the settings for the Date and Time options.
(For instructions, see “Using the System Setup Pro-
gram” in Chapter 2.)
Timer chip counter
2 failed
A chip on the system board
may be malfunctioning.
Run the System Set test group in the Dell Diagnos-
tics. (For instructions, see Chapter 4, “Running the
Dell Diagnostics.”)
Unexpected
interrupt in
protected mode
The keyboard controller may be
malfunctioning, or an installed
memory module may be loose.
Run the RAM test group and the Keyboard Con-
troller Test in the Dell Diagnostics. (For instructions,
see Chapter 4, “Running the Dell Diagnostics.”)
Warning! Battery

The battery is running out of
charge.
Replace the battery, or connect the computer to
AC power. Otherwise, activate suspend-to-disk
