My lenovo G780 won't turn on. I hit the power button and the lights turn on for a few seconds and just turns off again. The screen never even gets the chance to turn on. What should I do? I tried hard rebooting, and most of the common things already.

Open the system, if it has a removable CMOS battery, unplug it, hold in the power button for about 30 seconds. With wall power and main battery unplugged of course. Plug in wall power only, see if it turns on. If it does, plug in CMOS battery again and see if it works OK.

If not, likely the motherboard is bad.
