Memory Problems

Memory errors detected on startup

Check memory modules for correct seating and orientation. Reseat the memory modules if applicable (see “Upgrading or Replacing Memory” on page 41).

Computers using a dual-channel memory configuration require that memory modules be installed in pairs. If you require assistance, contact Alienware Technical Support (for more information, see “Contacting Alienware” on page 70).

Display Problems

If the display is blank

NOTE: If you are using a program that requires a higher resolution than your computer supports, it is recommended that you attach an external monitor to your computer.

The computer may be in a power saving mode:

Press a key on the keyboard or press the power button to resume normal operation.

Switch the video image:

If your computer is attached to an external monitor, press <Fn><F6> to switch the video image to the display.

Power Problems

When you press the power button, the computer does not turn on

If the AC adapter cable is connected to a surge protector or UPS, ensure that the surge protector or UPS is securely connected to an electrical outlet, is switched on and is working correctly.

Check that the wall outlet is working properly by testing another device such as a radio or lamp that you know works. If the wall outlet is not working, contact an electrician or your power company for further assistance.

If the problem persists, contact Alienware support (see “Contacting Alienware” on page 70).
