Hello I have a strange issue with this laptop: Procesador: Intel Core i5 3210M (2500 MHz - 3100 MHz) RAM: 8GB DDR3 (1600 MHz) Video Cards: Intel HD Graphics 4000 (integrated) NVIDIA GeForce GT 650M (DDR3) (1GB) It stopped working for no reason, it turned on, I could hear the cpu fan but It got no image , so i took it to a tech store and the guy manage to "fix it". It now turns on but it shuts down after 45 minutes with no warning and not by overheating, the tech guy has no idea why. I checked the charger with a multimeter and the voltage output is correct. Someone told me that this could be a "BIOS ME region issue, so it needs to be cleaned." but I have no idea how to do that Any help would be apreciated.
