Laptop Shuts Down Due to Overheating

Name: Kelly Susalla

My laptop continues to overheat ( I think) It will not even completly load up before shutting off and the fan runs very hard and the bottom feels very hot once it shut off. It is less than two years old. Is this a prpblem I can fix at home or do I need to take it in? I am not computer knowledgeable. Thanks for the help in advance!


 
If it feels hot on the bottom when shutting off it certainly sounds like it’s overheating. It’s normal for your laptop to feel warm on the bottom after some use, especially if running off of the battery, but it shouldn’t be hot immediately after bootup.

Are you running the laptop on a smothering surface such as carpet or a comforter that could be blocking the fan’s circulation? If so, try running it on a table or other surface that will allow the laptop’s vents to move air about.

It’s also a possibility that the fan on your CPU has gone out and that the exhaust fan is kicking on in overdrive to try to move enough air to cool the CPU down. Laptops heatsinks are not very large due to the small area that they must fit in, so their fans tend to turn on early and run fast the whole time. If this fan has locked up, then your processor will rapidly become much too hot and will subsequently trigger the BIOSes CPU temperature monitor to shut the computer down before any damage is done.

Also, your battery could be at fault. A damaged or defective battery can generate an excessive amount of heat very quickly, so you may want to have that checked out.

The only thing that I can in good conscience recommend that you do on your own is simply to make sure that any and all vents on the laptop are free of obstructions. If this is the case, then you’ll need a professional to look at the machine to determine where all of this excessive heat is coming from.
