Hello!
Mistave contacted me, because he has Dell Inspiron 15R SE (7520) on
which are not working 3 hotkeys located in the right upper corner.
After debugging we find out that this Dell Inspirion sends following WMI
event to dell-wmi.c driver:
=====================================================================
----------------------------------------
Left WMI key: Windows Mobility Center
Press: Key with type 0x0000 and code 0xe026 pressed
Hold: -
Release: -
Only the press event was observed. It does not repeat when held down.
----------------------------------------
Middle WMI key: Dell Audio With Preset Switch
Press: Key with type 0x0000 and code 0xe02a pressed
Hold: Key with type 0x0000 and code 0xe02b pressed
(code 0xe02a also repeats continuously)
Release: Key with type 0x0000 and code 0xe02c pressed
Code 0xe02a repeats, if button is held down. After about 3 seconds a
single code 0xe02b entry will also appear. When released before the code
0xe02b pops up, the code 0xe02c will appear. If released afterwards,
code 0xe02c does not appear.
----------------------------------------
Right WMI key: Dell Instant Launch
Press: -
Hold: Key with type 0x0000 and code 0xe025 pressed
Release: Key with type 0x0000 and code 0xe024 pressed
Code 0xe024 only appears, if the button is released within about 3
seconds. If held down for longer, a single code 0xe025 will appear. If
released after the code 0xe025 appears, the code 0xe024 will not appear.
=====================================================================
Such hold and release events in 3sec time period are strange and I'm not
sure how we should handle them. Any idea?
Also there is another problem. Driver dell-wmi.c ignores 0xe025 events
because on all other machines it is reported also by PS/2 internal
keyboard. But seems not on this Dell Inspirion. How to handle this fact?
Add a new quirk into dell-wmi.c code?
Mario, do you have a documentation or something which can prove above
observation that keys are really reported via such strange WMI events?
