💬 Laptop overheating and shutting down randomly

My laptop has started overheating and shutting down on its own during heavy use, especially when charging. I have already cleaned the vents but it is still happening. Could this be a thermal paste issue or something more serious? Any suggestions before I take it to a repair shop would be appreciated.

It could be thermal paste, but I’d check a few other things first. Monitor CPU/GPU temperatures under load, make sure the fans are actually spinning properly, and check whether the CPU is hitting unusually high usage. If temps are consistently very high even after cleaning, repasting and checking the cooling system would be reasonable. If it’s shutting down suddenly, I’d avoid pushing it hard until you figure out the cause.

This sounds like it could be a thermal paste or dust buildup issue. Try running a monitoring tool like HWMonitor to check your CPU/GPU temps under load, if they are crossing 90°C+, it is worth getting the thermal paste reapplied. Also double check that all the fans are actually spinning; a silently failing fan causes exactly this kind of random shutdown.
