Title.

so, my computer updated itself when i fall asleep try to work overnight. then i ran into this issue, usually, when the laptop is on battery, the display goes to 60hz, to save power, then ramps up again to 144 hz when it's plugged in, but after today, the display still goes down to 60 hz on battery, but won't go up to 144 hz when plugged in (i need to set it manually on the adapter), anyone having the same problem?
