When I move or lift up my laptop video on the screen becomes garbled and everything freezes. The laptop works fine as long as it stays on the desk but when I lift it up video goes bad and cursor freezes. After that I have to do a hard reboot.

Today I had to troubleshoot a laptop with similar problem.

The laptop was working fine on my bench.

As soon as I lifted the laptop the normal display changed to one pictured below. The screen freeze up and I had to reboot the laptop by holding down the power button for a few seconds.

I tested the laptop with an external monitor and external video failed exactly the same way as video on the laptop LCD.

The external video was absolutely fine when the laptop was on the bench.

But it failed the same way after I lifted the laptop.

When both internal and external video fail the same way, it indicates a problem with the video card. Most laptops have integrated video (video card is a part of the motherboard). If that’s the case, you’ll have to replace the whole motherboard.
