T400 screen/power/standby problem

Hi Guys,

I don't have much experience with hardware stuff so I will describe a little bit in detail here.

The problem started last week, I plug AC adapter into the laptop but none of the lights which indicate power and battery were turn on "green". I thought the lights were dead so I just went ahead and hit the power button but the LCD screen wasn't on. The system seemed to working normally as I could still hear the welcome screen sounds and fan on. I then shake my laptop around and suddenly the icon lights on again and the LCD screen light up.

A few days ago, the problem turned worse as it has happened more frequently. Now, everytime I move laptop around, the laptop has the potential to turn off the icon light and computer automatically go to "standby" mode and I had to wait for the icon light to go up again in order for the screen to show up.

Guys, i have done some searching and people said it has something to do with either the LCD screen or LED backlight or inverter or something

Please help me, please let me know what piece of hardware i have to buy in order to fix this screen

 

Anyone can help me please? Anyone anyone anyone
