My "Sleep" F1 button puts my Aspire 3 - A315 into Black Screen mode! No recovery!
My computer is about 2 months old and this has happened once before, where I hit the F1 key instead of the ESC key. It immediately went into "Black-Screen" mode, where the power and fan are running, but no display! Did a battery reset, Tried soft-reboot by holding the power key down for 30 seconds plus, unplugged all peripherals and tried "F2", ALT F10, and the CTRl, Windows,Shift + B" combo, all to no avail... It "Revived" by itself before, but I hit the key again and now it has been the same for a day and a half and counting...
