The battery is running out of
charge.
Replace the battery, or connect

System Flash Codes
Then 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 (see
Figure 3-4) 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 convolatile random-access memory
(NVRAM). This information is important to the dell support staff if you need to call for technical
assistance.
The Num Lock, Caps Lock, and Scroll Lock indicators flash briefly when the computer is turned
on. The flash codes, if needed, occur after the boot routine.
Figure 3-4. Flash Code Indicators
When a flash code is emitted, write it down on a copy of the Diagnostics Checklist found in
Getting Help and then look it up in Table 3-3. If you are enable to resolve the problem by
looking up the meaning of the flash code, use the Dell Diagnostics to identify a more serious
cause. (See
Running the Dell Diagnostics.) If you are still unable to resolve the problem, call
Dell for technical assistance. (See
Getting Help, for instructions.)
