I have more than 20 laptops in my organization with Windows 7 Enterprise Edition (32 Bit operating system) & i got a very strange same issue in all laptops. Lenovo T420 Shutdown automatically while on working. It doesn`t matter its on battery or AC Power. Kindly help me to resolve this issue if there is some type of patch or hardware changes required.
Many Thanks for your Support.
Waiting for your prompt response.

I have the same problem on my T520 where the OS just hangs and after couple of seconds shuts down. I made a thread earlier but nobody even bothered to answer...

T420, 4328 AA7, Windows 7 Pro.
Monitor suddenly black, there is a red line on the left side of the monitor. Then the laptop shutdown.
Laptop motherboard has already been changed by IBM technicians, but the problem persists.
