After traced S205 DSDT, I thought you will got a result is 0x71, please
help to use acer_ec.pl to confirm this register changed. Please give me
the value when wireless on/off.
And,
Please attached on dmidecode, just need:
dmidecode > dmidecode.log
I need add your dmi information to quirk table in acer-wmi.
Thank's
