Laptop turns on but screen is black.
My laptop turns on, and I can see the light on the keyboard and power button, but the screen is black. I tried taking out my battery and holding the power button and put the charger. It didn't work.
moe, the first thing I'd do is to attach it to an external monitor. If the external monitor comes on, it is something with your LCD. Could be the cable, the inverter or the LCD panel itself. If the external monitor does not work, you are having issues with your video card, which is an integrated part of your motherboard. You can download the service guide from here and it should help you with your laptop. Hope this helps, good luck.
check your RAM look if its broken or not plugged in
press the power button in 30 second you try
replace your memory ram then clean it with using erasure to clean the metal surface then put into second slot then try
Remove RAM and clean with an eraser clearly and replace...
i had the same problem , the screen is black but when I plug another screen by VGA it works ,
and the web cam works .
after 3 days searching and checking i found the problem and fixed it .
the problem is the video cable that connect the screen with the motherboard . because the screen closes and open many times , that causes the same cables are broken or corrupted .
the solution is to buy a new video cable ( before you buy, you have to specify the exact referance of the video cable ).
or , it is what i did ,
to fix the cable or cables that are broken by connecting them .
i did it it works correctly like it never happen. :)
Try booting your laptop using optical disk or bootable usb and see if your laptop gives you boot menu if not then either your screen has gone bad or VGA is overheating. if your screen has gone bad you can test that by connecting your laptop with an external VGA LCD using VGA cable and see if your laptop is displaying.
If you haven't already, you should remove the RAM, and reseat/replace one module at a time. Faulty RAM or a faulty RAM slot can cause no video display. You don't always get a beep code to tell you this.
This is quite common on laptops with Nvidia or ATI graphics chips, and is normally due to repeated overheating. How old is your laptop? If it is no longer in warranty, then your repair options can be quite costly. I had a Packard Bell SB86 which after 2 years use suddenly gave me the same problem. Check out this link: www.fixyourlaptopyourself.com. It explains how you can fix a range of laptops with this type of problem yourself, and without too much hassle - unusual technique, but it worked for me.
al this is due to the motherboard.....after using laptop do not overcharge....ok cut the chase lets go to the solution...
1. turn off and unplug battery n power cable
2. press power button for 5 min max
3. dismantle laptop carefully
4. clean fan compartment with small brush if deas alot of dust
5. unplug processor and check heat paste...if worn out re paste new heat paste
6. leave laptop dismntled for 24 hrs max...this to discharge electricity from board
7.now assemble and turn on....shud be working now if not
press power button off and on immediately several times and check screen.
It Can Be Causing The CPU Or GPU On The Motherboard.... You Can Consult Your PC Or Laptop To An Technician
By The Way.... Do Not Do It By Yourself It Can Cause Electrical Shock.

I also had similar issue. The laptop booted quite alright but nothing was showing on the screen. I tried most of the suggestions except removal of ram because I didn't have appropriate screw driver. What solved the problem is a post I saw on another site which is pasted below. It might be of help to you. Here's the post:
