Today I installed Windows 8.1 64-bit on a HP G62-b63SG notebook. Everything went fine and all devices were identified correctly – until the notebook activated the suspend mode and I woke it up again. The screen was black now and seemed to be turned off, while the machine was running… Well, at the first moment I thought that the display was turned off and not reactivated, but it was not the case! Only the backlight was off, which I realized in a lucky break…
