Except for no detected battery nor working brightness controls almost everything else for this Acer TravelMate P633-M laptop seems to be working see autoport in commit base:

Any hints for ACPI / battery / brightness and or EC (Nuvoton NPCE885PA0DX) to get improvements on this area?

See included OEM logs.
