Helpful Hints
If you encounter problems with the computer, monitor, or software, see the following list of general suggestions before taking further action:
●Check that the computer and monitor are plugged into a working electrical outlet.
●Check that the voltage select switch (some models) is set to the appropriate voltage for your region (115V or 230V).
●Check that the computer is turned on and the green power light is on.
●Check 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 Appendix A, POST Error Messages on page 187 for more information.
●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.
