My Tuxedo InfinityBook Pro 16 Gen 7 has a bulky heavy barrel charger so I wanted to use my 100W USB-C charger. But... surprise: when I plugged it in, the performance dropped by 70%! I asked on reddit and it turns out this is a hardware problem that affects all Tuxedo laptops, and there's no fix - https://www.reddit.com/r/tuxedocomputers/comments/1544o98/performance_drops_to_30_when_charging_via_usbc/
