I recently replaced the keyboard in my XPS-13 and in the process, of course, disconnected the button battery. When I tried booting into Mint I was greeted by some weird error, thinking my SSD somehow got scrambled. It didn’t even show up on the list of drives when using a live USB… Little did I know that when the battery disconnected, my BIOS restored to default settings and I had to set the AHCI mode again for the SSD to function properly. 😅
