I recently bought an XPS 13 9380 with i7, 16G of ram, 500G of storage.

Sometimes the fans are generating huge noises so I checked the Task Manager and found that the System process is taking around 25% to 50% of CPU Usage. I used Process Explorer to check threads in System process and found that acpi.sys is taking really huge CPU Usage. This issue may not happen right after booting up but would happen after some time. I am still not clear about what triggers this issue. I tried to do a full-disk scan using Windows Defender while no virus is found. The Operation System is Win10 Pro.

This issue is seriously affecting battery life and performance on my computer. Does anyone have any idea about how to solve this issue? Might it be caused by bugs in XPS's drivers?
