T420 support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hey devs

I've recently bought a ThinkPad T420 but i have several (non critical) 
ACPI issues with it. My dmesg say:

   thinkpad_acpi: ThinkPad BIOS 83ET65WW (1.35 ), EC unknown

... and I've tried install latest tp_smapi and insmod the modules from
the package, with no success. When insmod thinkpad_ec, dmesg says:

    thinkpad_ec: no ThinkPad embedded controller
  
... and tp_smapi and hdaps fails too because of the thinkpad_ec not
loaded. The hdaps modules that comes with linux 3.1 fails too.

When I place the laptop i my dock i get the following from dmesg:

  thinkpad_acpi: docked into hotplug port replicator
  thinkpad_acpi: unknown possible thermal alarm or keyboard event received
  thinkpad_acpi: unhandled HKEY event 0x6040
  thinkpad_acpi: please report the conditions when this event happened 
  to ibm-acpi-devel@xxxxxxxxxxxxxxxxxxxxx
  thinkpad_acpi: EC reports that Thermal Table has changed

Is there anything I can provide to you that could speedup the support?
Or do you know of any fixes?

/Martin
