HP Recommended
Laptop 15-bs0xx
Microsoft Windows 10 (64-bit)

Hi All,

I have a problem which frustrates me for so long already. The problem is I see High CPU 30-40% in task manager because of "System and System Interrupts". I have checked malware, formatted OS to newest Windows 10, downloaded and installed all OS Updated, Installed latest drivers, updated BIOS but no result. Because of High CPU  laptop`s fan is always in intense use and makes noise and heat a bit. Please, help me to solve this problem.

 

Thanks in advance!

@OrkhanR,

 

Welcome to the HP Support Community!

 

System interrupts appears as a Windows process in your Task Manager, but it’s not really a process. Rather, it’s a kind of representative that reports the CPU usage of all interrupts that happen on a lower system level. Interrupts can originate from software or hardware, including the processor itself. 

 

Interrupts are a form of communication between software and hardware with the CPU. For example, when you type on your keyboard, the respective hardware and software sends interrupts to the CPU to inform it about the task at hand and to trigger the necessary processing.

 

Try moving your mouse and watch what happens to the CPU usage of system interrupts to understand what that means.

 

Meanwhile, I recommend you run a system test on the computer to make sure that there is no hardware issue.

 

Here is how it is done.

  1. Turn on the computer.
  2. Immediately press the f2 key repeatedly, about once every second, until the UEFI menu opens.

When the UEFI menu opens, select the diagnostic test you want to run, and then follow the on-screen instructions.

NOTE: If you need to stop a diagnostic test, press esc.

 

Let me know how it goes and you have a great day!
