My laptop was getting random bad pixels all over once, and they'd disappear and come back all the time.

Since it had warranty I sent it in. The motherfuckers sent it back without fixing it. So I took a screwdriver and tried to fix it myself. My laptop wouldn't even turn on later. I sent it back and just told them it's the same problem but got worse. Then they fixed it lol.

Stupid sevicemen need something to be dead before they'll take a look at it lol.
