I need some help. I recently bought a Xiaomi Book Pro 14 2022 Ryzen 7 6800h, but when I installed Ubuntu (20/22/24), it won't load the OS unless the laptop is connected to a charger. As soon as I unplug it, it won't boot using only the battery. This doesn't happen with W11, only with Ubuntu. Any ideas? I haven't found anything anywhere else.
