Any question answered...

My laptop keeps overheating and suddenly shutting down. I hoovered the vents, but it didn't help. Looks like it needs to be taken apart and cleaned properly. Maybe even that is not a solution. Never disassembled a laptop. Any ideas what to do?

It sounds like you're not even sure what the problem is, overheating is just a guess? Instead wasting a lot of your time, probably pointlessly, get someone else to do it. It's amazing how many people say their laptops overheating and shutting down, when usually its a faulty HDD or something
