Hi i have an issue with my Hp Elitebook it was running fine until this morning when I tried turning it on..
I'll describe in detail what happens
When I plug in the ac adapter with the battery attached to the laptop it dosen't turn on don't hear fan spinning, drives booting or see and hear any lights on the keyboard or beeps.
When I remove the battery however and plug in only the ac adapter and turn it on I hear the drives booting and hear beeps and see lights on the keyboards with the fan spinning abnormally either too fast or almost barely..
The screen never shows anything it stays black in all situations..
Correction: the screen turns on sometimes with the fan spinning normally and the drives booting and the lights etc but turns off immediately after the Hp logo and turns back on but with the screen black..all this happens when the battery is detached but the ac adapter plugged in.
Any help or suggestions would be much appreciated!
 
It may be more than one issue. You may need a new battery, in regard to the reason it won't turn on with it in. And for the display try the following...

Try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

Thanks for the reply but the laptop sometimes turns on without any problems so are you sure it could be because of the GPU?
