My laptop is still under warrentee but asking here in hope of quick solution as I can not do without it for long.
In the last few days when the laptop has been left for a short while and goes into hibanation when it comes out the contrast of the display is show high I can't use it. I have to reboot. It's annoying when in the middle of a document or when a lot of windows are in use.
It's win 8 with latest updates.
