Subject: Re: [ibm-acpi-devel] thinkpad-acpi: fn-f4 issues

Hi,

I have also a X100e and the Fn-F4 (suspend-to-memory) and Fn-F12 
(suspend-to-disk) are not working. (no effect at all)

some dmesg lines:
[   15.358464] thinkpad_acpi: ThinkPad ACPI Extras v0.24
[   15.358468] thinkpad_acpi: http://ibm-acpi.sf.net/
[   15.358471] thinkpad_acpi: ThinkPad BIOS 6XET44WW (1.27 ), EC 
6XHT42WW-1.182000
[   15.358474] thinkpad_acpi: Lenovo ThinkPad X100e, model 287627G
[   15.360861] thinkpad_acpi: detected a 8-level brightness capable ThinkPad
[   15.360924] thinkpad_acpi: possible tablet mode switch found; 
ThinkPad in laptop mode
[   15.362664] thinkpad_acpi: asked for hotkey mask 0x040988fc, but 
firmware forced it to 0x000988fc
[   15.367253] thinkpad_acpi: setting the hotkey mask to 0x00ffffff is 
likely not the best way to go about it
[   15.367257] thinkpad_acpi: please consider using the driver defaults, 
and refer to up-to-date thinkpad-acpi documentation
[   15.378453] thinkpad_acpi: rfkill switch tpacpi_bluetooth_sw: radio 
is unblocked
[   15.389678] thinkpad_acpi: rfkill switch tpacpi_wwan_sw: radio is 
unblocked
[   15.390251] Registered led device: tpacpi::thinklight
[   15.390658] Registered led device: tpacpi::power
[   15.391086] Registered led device: tpacpi::standby
[   15.391470] Registered led device: tpacpi::thinkvantage

complete dmesg attached. (is this the "full kernel log"?)

PS: I'm using openSUSE 11.3 with 2.6.37 kernel (from suse's HEAD repository)
