Hi @1115, looking at your other post, the 6.6.4 kernel you indicate using should offer efficient power management.
What steps have you taken to test & tune?
If you’d like some guidance, please see my previous posts above.
At very least, my suggestion is to:
a) ensure amd_pstate is active and set it to balance_power or power
b) if running PPD, set to power-saver or balanced
c) enable usb autosuspend if it isn’t already
It looks like your 6800H has a base TDP of 45W but can draw more than double that!
Hope this helps
