When I turn on my Acer laptop the screen is black,when I press Func f6 it comes on for a brief moment,if I keep doing this for about an hour it eventually stays on all night,what is wron and why,thank you.
Is Fn F6 the squence to swap to external screen? if so you need to wait between each press or you will just cycle round to the net funtion.
something else to check is the screen off switch is not sticking down when you lift the lid.
