hi alfaone,

i believe the issue will be solved after re-installing the power management.

Yigit,

Did you forget this thread:

To the  OP,

     Only use the Lenovo driver for your Intel HD 3000 to use the OSD toggle to work.

@dragnoak

i believe it's not the issue in this case. user commented that the bar is visible but no animation.
