L450 - Problem with processor clock speed

2019-03-08, 15:32 PM

Hello
About six months ago, I had a problem where my processor would throttle to 0.79 GHz to save power (even running on wall-power).. I fixed this by updating the BIOS, and haven't had that problem since.

I have, however, gotten a new problem; My processor's clock speed has been fluctuating all over the place. Most of the time, it jumps between 1.69 GHz to 2.09 GHz. This is a bit annoying but I can fix it temporarily by restarting my computer. The base clock is 2.19 GHz, so it shouldn't be lower than that when running on wall-power.
Before this problem arose, I was usually turboing up to 2.89GHz when using it under load. 

 

Is there any fix to this major fluctuation in clock speed?

Thank you in advance :)

Hi !

 

Welcome to Lenovo Community Forums.

 

Are you still experiencing the same problem? Sorry for the late response.

 

CPU fluctuation can be a normal part of computer use, but it can also be an indication that a program is having issues or the computer is infected with malware. Please perform a clean boot where it starts with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your laptop. Please follow the steps here.

 

Regards,
