Hey guys I'm curious as to what anyone here thinks. I have an HP Envy Laptop running Ubuntu 15.10 and it has a 4th generation quad core i7. For some reason since I first installed it my fan spins up, it gets hot and drains the battery quite quickly. I started digging and noticed that one of my CPU loads was at a constant high of 90%. I couldn't figure out why. I noticed that when a usb plug is plugged into the laptop this magically stops. With one not plugged in it spins right up. Any thoughts on why this might happen? I used TOP command in terminal and system monitor to determine this with pictures:

Here are some links to the research that I have done:

8 CPU and one is at ~100% all the time

Why is ksoftirqd/0 process using all of my CPU?

used powertop from the Ubuntu documentation pages and again pointed to usb/xhci stuff. but did not matter. i upgraded to kernel 4.4.1 and it stop doing the cpu load thing so i guess il never know 8(.

I was directed to this site by a coworker and it helped me incase it helps anyone:
