Firstly it sounds as if it could be a heating issue, check CPU fan functionality. Make sure that the air intake and the vent out are not blocked by dust build up. It is quite common for L/T'S to go in to shut down when over heated.
Hi all i have Toshiba L850, CPU Intel 3610QM, GPU Radeon 7610M, 8GB RAM and V300 128GB SSD
It shut down every 30 minutes randomly i try format Windows but no effect look's like bios problem. I try work only on battery or without battery only in AC but no effect.
Do you have any Idea or any self Experience with this problem. Thanks
