Helpful Hints
If you encounter problems with the computer, monitor, or

working electrical outlet.
■ Check to see that the voltage select switch (some models) is
set to the appropriate voltage for your region (115V or 230V).
■ Check to see that the computer is turned on and the green
power light is on.
■ Check to see that the monitor is turned on and the green
monitor light is on.
■ Check the power LED on the front of the computer to see if it
is flashing red. The flashing lights are error codes that will
help you diagnose the problem. Refer to “Interpreting
Diagnostic Lights and Audible Codes” on page 33 in this
guide for details.
■ Turn up the brightness and contrast controls of the monitor if
the monitor is dim.
■ Press and hold any key. If the system beeps, then the
keyboard should be operating correctly.
■ Check all cable connections for loose connections or
incorrect connections.
■ Wake the computer by pressing any key on the keyboard or
pressing the power button. If the system remains in suspend
mode, shut down the computer by pressing and holding the
power button for at least four seconds then press the power
button again to restart the computer. If the system will not
