My laptop (new 2 months ago), an ASUS K50AD running Windows 7 Home Premium (64 bit), sometimes fails to start the backlight to the LCD screen when it wakes up from sleep mode, making it virtually impossible to see what is on the screen. I can't discern any pattern from when it does it, except that it seems to come in clusters.
The backlight has no trouble starting when waking from hibernation or a cold boot. Trying to adjust brightness settings while the backlight is not working yields no results. My monitor driver and graphics card driver are both up-to-date (as is my ATK driver... I don't know what this does, but it was mentioned in a Google search result when I was trying to find a solution to my problem).
Could anyone give me any information on what is causing this and how I might fix it?
