So I have a toshiba satellite series laptop, one of the ones that got re-called a few years back for overheating issues, i've found my way around the overheating issue but right now it's doing something else, when I turn it off or put it in sleep mode it will not come back on, the harddrive and processor turns on but the screen stays off, the only way I can get the screen to turn on is if I hook up my dads computer monitor to my laptops vga output, I wait for the monitor to turn on then my screen turns on, I disconnect it from the monitor and it works fine up until I turn it off then I have to repeat the process, any idea what could be the problem? I feel as if the computer isn't sending the screen the signal to turn on, it's weird, this started happening out of nowhere, didn't drop the computer or anything.
