Memory

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 37).

Computers using a dual-channel memory configuration require that

memory modules be installed in pairs. If you require assistance, contact

Technical Support (see “CONTACTING ALIENWARE“ on page 61).

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.

If your computer is attached to an external monitor, press to switch

the video image to the display.

Power

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 61).
