I have brought Lenovo T410 two year before is now overheating and shutting off at the time docked. It used to be gets really hot, fan spins with the great speed at the full flash and then suddenly it turns off automatically. I wanted to know whether it is due to the multiprocessing that I use to do at the same time, such as playing songs, compiling program, iTunes, zipping up to a approximately 1Gigabyte file. The ThinkPad that I was using before this never got such problem. As this is new version I am not able to find the solution. If you can suggest any solution then please help me. I am waiting for your idea.
