My laptop was working fine but recently when I tried on switch on, dislay does not work. All the lights starts and also DVD room gives the voice but nothing on LCD. After some time it beeps two times. Tried to connect with some other monitor still it does not work. So I concluded that it's not the problem with LCD.
Kindly suggest any thing that what's the problem and what can I do for the fix.

@mudasir this is can be caused by loose memory or bad video. Remove all memory modules and check if the beep code changes. You can also try to reset the BIOS by removing the CMOS battery, the main battery, remove the RAM and AC power adapter. Then hold the power button down for 15 seconds or longer. Reassemble and see what you get. Here is how to disassemble your computer. You can download the service manual from here.

@oldturkey03 I tried by doing the same. removed the battery and adopter and hold the power button 60 sec. But it did not worked.
You checked your RAM module by removing those and seeing if the beep code changes?
