So I have looked all over for the answer to my question, but I havent found any threads that exactly match my issue. I have a 2016 Alienware 13 R2. Specs shouldnt matter, but its 500gb hdd, 16gb ddr3 ram, NVIDIA GEFORCE GTX 960m with 2gb dedicated video ram. Every once in a while, some days more often than others, my laptop freezes. It only does this when plugged into ac power and it always 100% of the time unfreezes when I unplug the power cord. The screen is fine, but every part of the pc including the pointer and the keyboard are all frozen until I unplug it. I plug it back in and its fine... for a while at least. I have tried disabling my processors in device manager after reading a similar but different thread, which helped for a while,m but its back. Any ideas? All drivers are up to date, BIOS as well. O have reset this computer once before because I couldnt keep up with desktop clutter and it was slowing down, but the issue is fairly recent.
