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.).

I second that. Amazing easy to use, configure, supports (LetsEncrypt) certificates via DNS-01 challenge and integrates with ease with most DNS providers.

Paired with authentication providers (keycloak, authelia, authentik), the “advanced” textbox lets you do forward proxying really easy, or customize your “basic proxy”.

I’m not sure how many of these features are present in Traefik, it would be really nice if any of you know if any of these are easily supported in it:

• Forward proxying
• Custom rewrites (nginx internal; rewrites)
• Unattended DNS-01 support with ACME (LetsEncrypt)
