First of all. Sorry about spam.
This is mass update for our bugs. 

Sorry if you feel this annoying but with this trying to understand if bug still valid or not.
If bug investigation still in progress, please ignore this and I apologize!

Hi Jani.

I'm no longer in possession of the thinkpad, so I will not be able to provide further information. Feel free to close the bug, sorry!
