Hi,
I have created a keymap for few missing keys on my notebook.
Here there are:
0x84 bluetooth # bluetooth module missing
0x92 media # acer arcade
0xD4 bluetooth # bluetooth on
0xD9 bluetooth # bluetooth off
0x84 is sent when bluetooth button is clicked, but in fact the module is
missing, as the can in my laptop.
However there is a 'hack' to make the EC think that bluetoth module is
enabled. Then pressing the button enables the blue led, and sends
0xD4/0xD9
For general information, the EC reg 0xBB control that behavier:
BB.0 WLAT - wireless enabled - toggles both led state and rfkill, reflects current hw state
BB.1 BTAT - bluetooth enabled - toggles that led, and probably toggles bluetooth rfkill
BB.2 WLEX - wireless present - if unset, button doesn't work, rfkill always enabled
BB.3 BTEX - bluetooth present, same as above, and here unset by default
My laptop model is 'Aspire 5720G', however dmidecode, shows just
Aspire 5720
Following udev rule works:
ENV{DMI_VENDOR}=="Acer*", ATTR{[dmi/id]product_name}=="Aspire 5720*", RUN+="keymap $name acer-aspire_5720g"
Best regards,
Maxim Levitsky
