Who can repair it?
The computer CPU burned out. Even just typing a few words makes it heat up. The small fan spins fast but can't dissipate the heat. (The G620 is half a century outdated, yet there's still one for over 400 yuan...) The engineer uncle's laptop also overheats; these days, you can't rely on imported goods. I don't know if I can replace the CPU. (Does the RAM have anything to do with it?) (The manufacturer's advertisement says it's guaranteed for many years, warranty for many years, it can work for many hours... but it stops working right after the warranty period.)
