Labtop Screen Remains Blank

When I hit the power button, all the lights come on but the screen remains blank. It isn't in sleep mode and there is enough power because we have it connected to a power source. What else could it be?

    I have an Everex StepNote NC1500, the screen went Black, but I can see an image faintly by looking at an angle.

    I hooked up an external monitor an everything works fine on the External monitor.

    Any ideas? Can this be a do-it-yourself repair?

Connect to external monitor to rule out bad video card. (remember most laptops have to toggle between internal and external display by using the <FN>+ <F?> key, mine is FN F5.)

If the external works then the problem is

  1. Inverter board or
  2. TAB welds at LCD or
  3. CCFL Cold Cathode Florescent Lamps (backlights)

go to control panel > power options. Turn off hibernate and sleep mode, change all settings to never sleep and change the setting for "when closing the lid" to "do nothing" sleep mode, hibernation can destroy the registry on these laptops, you are better off turning that garbage off and just letting it run.

Acer Aspire 3610 stuck in sleep mode


When you turn on your laptop do you see the P.O.S.T screen or it just remains blank? and also while booting up do you get any beep sound?
Try to boot your computer in Safe Mode by Tapping F2 (or Del in few laptops) key after pushing Power Button.
let me know what happens.

Blank screen. Remains blank


Power down, remove the battery, remove the power plug. Hold down the power button for at least 30 seconds. Remove and reinstall the memory module(s). Re install the power plug and try to power back up and see if it works. If it does, reinstall the battery ad you're done. If not, get back to me for some more ideas and further diagnosis.
Thanks and have a good day!
