  • I have had an identical problem a few years back, with a Samsung 2 in 1 that worked perfectly on AC, but had exact issues on battery.

    It was the “power saving” capability of the GPU that triggered it on battery. So simply disabling this is the integrated Intel GPU control panel (in Windows) fixed the problem. Laptop is still running now and works with my sister in law.




  • I’m a fan of SystemRescue. It’s specifically designed for backing up and fixing disk layouts, and it supports both BIOS and UEFI booting.

    I’ve never tried it on Secure Boot enabled devices (I usually disable secureboot before troubleshooting systems), so I do not know if they use a valid signed efi-stub.

    For “simple” stuff, I usually boot a live ubuntu image. If the machine has sufficient RAM, I can get away with installing quite a few packages that I need for troubleshooting (gparted, gdisk, etc.).
