Thanks Christopher. Unfortunately your link to Lenovo has no BIOS files
to download for Ubuntu environments.

What's the most easiest way to upgrade BIOS on my machine then?

  Error parsing PCC subspaces from PCCT

Status in linux package in Ubuntu:

Bug description:
  On my Thinkpad laptop I am seeing this error every time after the boot
  in the dmesg output:

  "Error parsing PCC subspaces from PCCT" (Portable C Compiler)

  The attached log files should reveal more. I have no idea what it
  means but seems serious. Hope you can solve this for once and all?
