    hi there,

    After power on, back light of my laptop(acer aspire 5920g)turn off in couple of second. Screen is working but no backlight or actually very low back light. i could able to saw screen with help of flashlight and connected my computer to external monitor. its working ok. And i am still able to switch on turned off screen for couple of second by using full brigtness button on keybord. probably it means system see a problem and turn off screen.This problem also start slowly and increased over the time. first times turn off about 1 hour period. i thought it coused by heating problem. Slowly bocome more frequent and in the and its start to turn off just after power on. So what could couse this and how could it be solved.
