I have an Aspire One D255E. Everything was working fine and we replaced the LCD screen. Then, we get nothing but a black screen of death. Can't even boot into BIOS. I should mention that I also tried hooking up to an external monitor and still the same black screen of death. I could really use some help.
Are you sure you hooked it up right? There is a little button that gets pressed when you close the laptop. It turns the screen off and usually puts the computer into sleep mode. Is this button stuck pressed down?
