So today i was working on my computer (a toshiba laptop) and randomly the screen went black. The blue light that determines my computer is still running remained on. I have tried restarting it, taking out the battery, unplugging it from the adapter, etc. Nothing will work! The weird thing is that a couple of times i have actually gotten it to turn back on, but after a couple of minutes it does the same thing and the screen goes black. my battery is full and definitely works. Whenver i turn it back on the blue light comes on and i can feel the hot air coming out of the side of the computer for less than 10 seconds, after that i hear no sound generating from the computer...does anyone have any idea what could be wrong? I really really really need use of my computer, so i would appereciate it if anyone could give me any suggestions!
Thanks SO much!!
