Video and Display Problems

If the display is blank

CHECK THE LIGHT — When the light is blinking, the computer has power.

•If the light is blinking, the computer is in standby mode—press the power button to exit standby mode.

•If the light is off, press the power button.

•If the light is on, your power management settings may have caused the display to turn off. Try pressing any key or move the cursor to exit standby mode.

CHECK THE BATTER Y — If you are using a battery to power your computer, the battery charge may be depleted. Connect the computer to an electrical outlet using the AC adapter, and turn on the computer.

TEST THE ELECTRICAL OUTLET — Ensure that the electrical outlet is working by testing it with another device, such as a lamp.

CHECK THE AC ADAPTER — Check the AC adapter cable connections. If the AC adapter has a light, ensure that it is on.

CONNECT THE COMPUTER DIRECTLY TO AN ELECTRICAL OUTLET —

Bypass power protection devices, power strips, and the extension cable to verify that the computer turns on. To access the help file, see page 26.

ADJUST THE POWER PROPERTIES — See the Tell Me How help file or search for the keyword standby in the Help and Support Center. To access help, see page 26.

SWITCH THE VIDEO IMAGE — If your computer is attached to an external

monitor, press to switch the video image to the display.

HINT: If you are using a program that requires a higher resolution than your computer supports, Dell recommends that you attach an external monitor to your computer.
