So a couple of days ago my laptop gave off a burning smell and then shut off, I open up the bottom and the smell seems to come from the fan. When i try to turn it on nothing happens. I have an old alienware m15x. any other info you need just ask.
Did you notice the fan being louder the last few days?,If the answer is yes my bet would be you just fried your motherboard,When you connect power and press the power button is there ANY sign of life at all?
Maybe you should replace the battery and retry. Nothing? Replace the fan if you can. Nothing? Buy one of those laptop coolers, remove the fan, open up the back, and let the cooler do the work for you. Nothing? Get the thing fixed. BTW, would you ever leave the thing on longer than usual?
