Surface pro 4 - clock speed of CPU keeps the same

Anonymous

After updating to windows 10 (1607), I find that the clock speed of the CPU keeps to be 2.92GHz when plugged, and to be 2.47GHz when using battery. My surface pro 4 has a core i5 CPU. It seems strange because the clock speed of CPU should change with the workload in the Task Manager. Does anyone have the same problem?

Fixed with today's update. Thanks, MS!

NOTE: I had to reboot twice after updating. So if anyone is not seeing the fix try a restart.

In addition to the hints provided, thanks by the way!

If rebooting twice still doesn't fix the cpu scaling issue, reset your power scheme to default then reboot again.

Fixed for me as well. Thanks for the hint about the second reboot. I also had to reboot twice even though the system never prompted for the second reboot.

Hi Barb,

Thanks for the news! Do you happen to know from your contacts if this problem has an impact on battery life?

There are those who claim that it's just a graphical glitch in the UI which shows the max speed used but does not really reflect the actual CPU utilization.

Any useful feedback is appreciated!
