Thinkpad T400 not booting, lights below the screen & HDD turning on & off in a loop

I put my Thinkpad T400 in hibernate, but next morning I could not boot. When I press the power button, the lights below the screen turning on and I hear the sound of the hard disk, and the turns off. I do not even see anything on the screen; it is just black. The process keeps on repeating in a loop, unless I press the power button to turn off.

 

I have tried the static charge removing trick.

 

I have also removed the hard disk put it back again, but did not work either. 

 

Please help.

Solved the problem myself.

 

Removed the internal battery and reinstalled it after 30 s.

 

It worked perfectly. Typing from it now. Smiley Happy
