Hi, I have a laptop that if I inadvertently let go to sleep, for instance by it not being plugged in and the battery flattening, then when I try to start it up the screen stays off. No matter what I do I can't get it back on - I have even removed the memory, HDD and the battery and that doesn't work. Bizarrely if it is left for about a day it works fine. Any ideas? The laptop is an Alienware M17x on Win 10.
Edit: Extrenal screens work fine when attached to it when it is doing this.
