So does it sound like your laptop is running and booted up all the way except the screen is blank? if so try the steps below:

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

Power on - blank (black) screen


Disconnect the monitor signal cable from PC and switch on your monitor. It should show some logo with Red, Green and Blue colors with a message similar to "No signal". If so, your monitor is working fine. Sometimes if the brightness and contrast is set to zero using controls present in the monitor, it will not show up anything. check wheather somebody set your monitor brightness and contrast to zero. If so incease them. As a last try connect to different PC and check before approaching a service center. I hope this will help you out. :)

Blank Screen..Will not power off


The flash light test only works with lcd monitor as they have back lights. Double check the connections again, also, if you can borrow a monitor try it on your pc, it may be your graphics driver needs to be uninstalled and re-installed, but you will need a monitor to see.
