Solving Problems
If the power light is blinking white — The
computer is in standby state or the display may
not be responding.
Press a key on the keyboard, move the •
connected mouse or a finger on the touch
pad, or press the power button to resume
normal operation.
If the display is not responding, press the
•
power button until the computer turns off
and then turn it back on.
If the problem persists, contact Dell (see
•
“Contacting Dell” on page 76).
If you encounter interference that hinders
reception on your computer — An unwanted
signal is creating interference by interrupting or
blocking other signals. Some possible causes of
interference are:
Power, keyboard, and mouse extension cables. •
Too many devices connected to a power strip. •
Multiple power strips connected to the same •
electrical outlet.
Memory Problems
If you receive an insufficient memory
message —
Save and close any open files and exit any •
open programs you are not using to see if
that resolves the problem.
See the software documentation for minimum
•
memory requirements. If necessary, install
additional memory (see the Service Manual
at support.dell.com/manuals).
Reseat the memory module(s) into the
•
connector(s) (see the Service Manual at
support.dell.com/manuals).
If the problem persists, contact Dell (see
•
“Contacting Dell” on page 76).
If you experience other memory problems —
Run the Dell Diagnostics (see “Dell •
Diagnostics” on page 59).
If the problem persists, contact Dell (see
•
“Contacting Dell” on page 76).
