Hot aspire laptop wont turn on

Laptops that require cool air for fan operation, in order to keep the unit below maximum temp, in other words, any unit that does not employ passive cooling, should not EVER be put into a bag, sleeve or luggage unless it is turned completely off. Ever.

Even if you set the advanced power options for LAN and hardware to the disabled setting for waking, there is always a chance of something waking. It takes about ten seconds for a device to power on and boot to the desktop, so if that is too long to wait when you reach your destination then perhaps you should look at a device with passive cooling that does not require cool air for operation.

Likely you've cooked the cpu, fan bearing, motherboard or memory. It only takes about ten to thirty seconds for cooling to be required once the unit powers on and after that it's anybody's guess whether it will be usable once it's removed from the bag. Usually it's not. Protection schemes that are supposed to shut the unit off if temps exceed a certain spec only go so far and don't always work until beyond the point where damage has occured. Best advice would be to allow the unit to cool completely, while shut off, and then try again.

If it does not power on you will need to get a new device. There is no fixing a cooked laptop. You should be able to transfer the hard drive to the new device though so you do not lose that data. Lesson learned. Devices should be shut down when traveling. No exceptions.
