Deferred Procedure Calls and Interrupt Service Routines High CPU Usage?
Deferred Procedure Calls and Interrupt Service Routines High CPU Usage? Hello,
Recently I have noticed higher than normal CPU usage from my laptop which I know will reduce battery life, cause higher temperatures and slow the computers performance.
The task manager did not tell me too much so I decided to have a look in the Resource Manager.
Sure enough under the CPU tab of the Resource Manager there is a process called System Interrupts that has a description of "Deferred Procedure Calls and Interrupt Service Routines" with a average CPU usage of about 30%.
usually to resolve this I restart my laptop and everything goes back to normal and the process is back down to 1 - 5 % CPU usage.
