This is a miracle! For a year now I've been struggling with the problem that my 5-year-old Carbon 1 Generation switches off spontaneously. Lenovo did not help. I spent hours updating the BIOS, messing around with Windows and BIOS settings, disabling built-in devices like Wi-Fi and BT, and even buying a new internal battery. The last theory I ran into was that my old power supply (all 3 actually) couldn't take it anymore and a brief power "dip" when plugging it in or even starting a video was causing the laptop to freeze. Well that theory seems correct as I haven't seen any of these issues even once with this new PSU!
