I have an HP Pavilion (15-p213cl) which is about 18 months old. Suddenly it has began shutting down for overheating. After being unplugged and allowed to cool overnight, it still had this behavior. However, the fans blow cold air, and nowhere on the laptop itself does it feel hot.

This behavior persists when being run on battery and with the battery removed while plugged in. Specifically the computer will boot as normal, but after about 20 seconds the fans will kick on. They progressively run faster until about 2 minutes has passed, then the computer turns off.

The computer was taken to a shop, who checked the heat paste and said that was well, but they didn't have anything else to do. The back is easy to open, and it's essentially a brick at this point, so I've got no problem messing with it, but software options aren't likely to work considering the aforementioned 2 minute timeline.

Any help with this problem would be appreciated. I'm not super savy on the hardware side of things, so any pictures would be helpful.
 
Not much of a shop if they didn't give you further diagnostic.

The symptoms suggest a temp sensor is giving you false reading. Are you running a monitoring app that tells you which sensor is heating up? Am not absolutely sure but there maybe a way to reset/calibrate these sensors, Google see what you find. Then of course you should ALWAYS clear CMOS see what happens.
