The embedded controller (EC) returned data when none was requested. (T420s)

Anyone also seeing this warring in system log running Windows 8 or Windows Server 2012 ?

 

: The embedded controller (EC) returned data when none was requested. The BIOS might be trying to access the EC without synchronizing with the operating system. This data will be ignored. No further action is necessary; however, you should check with your computer manufacturer for an upgraded BIOS.

 

Should i just ignore it ?

This message normally appears permanently, if TPFanControl or PFControl is installed and the Start-Programs-TPFanControl-optional-acpiecnl was not used to turn off the logging these events..

Thanks Smiley Happy

 

I had TPFanControl in my mind - but good to know.
