What causes a white screen on Lenovo G580 (20150)?

Question

Lenovo

There is a laptop Lenovo G580 (20150). Windows 8 x64. When moving the screen forward or backward, sometimes the screen turns white, but the laptop works and responds to all commands, music or video is played, but the screen remains white. I tried to move the screen again, but it does not help, it's still white. When you press the on / off button, the laptop goes to sleep and if you turn it on again (even if you leave it in the same place where the white color appeared), the screen lights up and everything works. I tried to change the drivers for the built-in (Intel HD 4000) and external (Nvidia 635M) vidyuhi, but it did not help. Has anyone encountered such a problem? There is no desire to carry it in the SC yet, since it can be delayed, but there is no other laptop.

Answer 3

Recently they brought such a laptop - after an unsuccessful disassembly - they pressed the cable into the connector, it broke. In this model, everything is fragile from the cable to the lvds connector on the board.

The problem was in the loop. When the lid was closed, it pinched the cable, from this it broke and turned off even if you just move the lid a little. Replacing the cable solved everything.
