I have a Dell Studio 1558 laptop which was purchased in July 2010 and I am now facing a problem with it. The laptop switches off automatically after working for around 15 minutes. When I gave it to the Dell authorized service center, they said, I need to replace the mother board.
I then gave it to an another service center and they said that the in-built ATI Radeon 5470 chip is faulty, and it needs to be replaced.
Could replacing the ATI work or should I be looking at a new board?
