Solving Problems
If the power light is breathing white — The
computer is in standby 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 93).
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 93).
If you experience other memory problems —
• Run Dell Diagnostics (see “Dell
Diagnostics” on page 72).
• If the problem persists, contact Dell (see
“Contacting Dell” on page 93).
