Power
Your computer will not turn on
•
Make sure that the power cord is connected to
an AC power source and to your computer, and
that your computer is turned on. If your power
cables are connected to a power strip, make sure
it is turned on.
•
Test the outlet by plugging in a working device,
such as a lamp.
•
Make sure that the power cord is free from cuts
or damage, and replace any damaged cables.
Display
The screen resolution is not correct
•
Change the screen resolution in Windows. The
computer is on, but there is no picture
•
Make sure that the computer is not in Standby
(power-saving) mode.
•
Make sure that the monitor is connected to a
power outlet and to a video port on your
computer, then make sure that the monitor is
turned on. If the monitor is on, its power LED
should be on.
•
Adjust the monitor’s brightness and contrast
controls. For more information, see the monitor’s
documentation.
•
Check the video cable for bent or damaged pins.
•
Connect a display that you know works (such as
a monitor from another computer) to your
computer. If the display still works, the original
monitor is faulty. If the display does not work,
either the computer’s video card (if installed) is
faulty or the on-board video is faulty.
