Helix CPU frequency limited to 0,3 GHz after replacement of mainboard (Win 8.1)

2014-12-17, 7:30 AM

Hi,

 

I have a weird problem: The mainboard of my Helix was replaced by Lenovo because it was defective. Now, the CPU frequency does not exceed 0,3 GHz (16% CPU utilization). The laptop is unusable because it is soooo slow. See the screenshot below.

 

The technician who exchanged it says: "hardware is ok, please "Format C:", it's a software problem " I don't want to do that.

 

The Lenovo support says: "We don't know."

 

I tried to run and reinstall Lenovo Solution Center to run a hardware scan, but the service doesn't work.

 

Who can help? Is this a software or hardware problem?

  • Do battery levels have any influence on this?
  • Does it change anything if you unplug the charger?
  • Did you hard reset both the tablet and the base using a pin?
  • Do you have the latest BIOS?
  • If so is "Cool Mode" turned off and power settings set to "max performance"?
  • Do you have the latest Lenovo Power Management (PM) driver installed?
  • Did you try switching around between power plans (in Windows - RMB on the battery icon)?
