Hi,

My friend has a gateway computer. The problem is the following : When she opens her computer's lid, depending on the inclination, there are huge spots of colors that appear throughout the screen. Some times, she can't see a single thing on her screen; she has to change the lid's angle in order for the screen to come back to normal.

With these information, I was wondering if anyone of you could give me a hint as to the problem comes from a bad contact between the screen and some other hardware material or if it comes from something else that I have not thought of.

If the problem is a bad contact, do you think there would be a way to fix it myself by opening the computer or is it a piece that is broken or something like that.

The angle-dependent, multicolored blotches described by point to a hardware problem in the lid rather than a software/driver issue. Both and are on the right track: the usual causes are wear or breakage in the thin video flex that runs through the hinge, or damage to the LCD layers themselves. A few simple checks will quickly narrow it down.

  1. Back up data and shut the laptop down; remove AC power and, if possible, the battery before opening anything.
  2. Connect an external monitor. If the external image stays clean while the laptop panel misbehaves when you move the lid, the fault is in the lid assembly (cable or panel). If the external shows the same problem, suspect GPU/motherboard.
  3. Check for the artifact in BIOS/POST (before Windows loads). If present there, it is hardware.
  4. With the lid open and the machine on, very gently change the angle and press lightly near the hinge and screen edges while watching the image. Localized changes near the hinge point toward a failing flex cable; blotches that change when you press the glass point toward panel damage. Do not press hard.
  5. If comfortable, reseat the panel connector (LVDS/eDP) after removing power; otherwise take it to a shop.

Typical fixes are replacing the hinge cable or the panel (or the whole lid). If under warranty, use manufacturer service. If not confident with delicate disassembly, professional repair is recommended to avoid making the damage worse.

This sort of thing is usually a kinked or shorting flat ribbon cable in the lid/body interface. Needs expert repair.

Suspishio is right. It can also be caused by micro fractures in the lcd surface, which allows the screen to flex beyond where is should normally go. Either one needs to be fixed by an expert.
