My acer an515-42 ryzen 2500u cpu is hard locked to 1.6 ghz in battery mode, on AC power just runs fine.
in battery mode this renders the notebook to a useless lagging pile of.... So please HELP!!! Acer support igoring me for 1 year, i written dozens of support tickets and no answer.
With original bios 1.06 it was okay with high clock speeds on battery, but after bios update everything is wrong.
I cant downgrade bios, because 1.08 and newer bios is only avalible at support page.
