Hello,
I have a Thinkpad Helix, on which I've installed Ubuntu, in different
versions, at different times.
When I resume from a standby operation, the dock led flashes. If I detach
the screen and attach it again, the led stops flashing.
The syslog shows multiple instances of this error when the led flashes:
Jun 14 17:29:07 amiga kernel: [ 9428.704280] thinkpad_acpi: unknown
possible thermal alarm or keyboard event received
Jun 14 17:29:07 amiga kernel: [ 9428.704291] thinkpad_acpi: unhandled
HKEY event 0x60b0
Jun 14 17:29:07 amiga kernel: [ 9428.704296] thinkpad_acpi: please report
the conditions when this event happened to
ibm-acpi-devel@lists.sourceforge.net
Is there anything I can do (aside ignoring and detaching/attaching)?
Thanks.
