BugFix

It is a known problem for the X220 Tablet (other models may apply), that there is a problem concerning the CPU throttling in LINUX.

  • Syntoms vary for different kernels and distributions. Eg in ubuntu the CPU speed gets blocked at low rates and the computer becomes very slow until reboot, in Opensuse the entire desktop freezes (only mouse pointer working) and switching to console is not possible.
  • Solution is to disable the power management in the BIOS (at least disable BIOS CPU speed throttling). This has no major affect on battery life since the OS is still able to throttle the CPU when neccessary.
