I thought need to check with Ike for more detail why the Fn+F5 key not
work on S205.
As I know on Thinkpad machine, the hardware switch causes killswitch set
to hard-block, and Fn+F5 causes killswitch set to soft-block.
Ike,
need your comments for Fn+F5 key and wireless hardware switch on
ideapad. How does it implement on ideapad?
- press Fn+F5: soft-block wireless killswitch?
- wireless hardware switch: hard-block wireless killswitch?

0x52 is zero maybe means the Fn+F5 will not do anything.
Could you please help to double check it by the following ways?
a. Please make sure CONFIG_ACPI_DEBUG=y then run the following command
by root:
echo 0xFFFFFFFF >/sys/module/acpi/parameters/debug_layer; echo 0xF
>/sys/module/acpi/parameters/debug_level
Then please press Fn+F5 key and attached dmesg on mail, we can know
find out which _Q method mapping to this key.
b. Please run this command by root:
perl acer_ec.pl := 0x52 1
Then press Fn+F5 key, does it have anything changed?
Thank's
Joey Lee
