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
Joey Lee
