Greetings,

 

I'm having an issue that my CPU is constantly loaded at between 14-25% even when idle as stated in the title.

I've done fresh installs with with no updates, with only MS updates, and fully prepped as-I-would-use-it configuration and they all eventually had the same problem within an hour or so of usage. The results have been slowed system and CPU not throttling at all and remaining at full turbo speed.

 

It's always a process called "System" and "System interrupts" but, mostly "System". I've tried various things to try and fix it such as putting the system to "High Performance" in the power plan, updated the audio drivers, along with updating the ethernet/Wi-Fi drivers since they were the ones I read were solutions to my issues. None of them worked.

 

I'd appreciate it someone could help me diagnose and hopefully fix my issues.

 

Thanks for taking the time to read.

 

 

My system is an HP 15-d035dx upgraded to 8GB RAM.

Download and run Sysinternal's Process Explorer -

Double-click on System and see what it's running.

Seems like it's ACPI.sys based on inspecting the properties of the process "System". Any idea what this means?

You might try this solution from Tom's Hardware...

What an unusual solution. Switching it to "Power Saver" mode seems to have done the trick. In any of the other power profiles, it immediately exhibits the CPU loading. I did the same custom power profile in "Power Saver" as I did in "Balanced" Mode but it still works. It's like the same power profile but different names but the Power Saver choice settles the CPU load. Weird.

 

Thanks jwoods301. I'll monitor the CPU for the next couple of days to see if it sticks.
