Surface Pro 3 High CPU load when idle, high system cpu load

Anonymous

Has anyone else noticed that coming out of sleep or herniate results in unwarranted high cpu load from system interrupts?

I have all the latest firmware and updates loaded. But using sleep even sometimes a cold boot I get this issue.

How can I fix this please. Its killing my battery life.

Oh!! I just checked it again as I wanted to make a screenshot and now it's working! I don't know what changed. The only thing I did was that I originally enabled Hyper-V but when it started interfering with my WiFi connectivity I disabled it again, so maybe that's what was necessary.. I used to have constant high "System Interrupts" process running, but disabling one by one I found out that an Adobe startup process was causing it, so I disabled it and it seems to have fixed the issue. Either way, thanks for your responses!

Dear Clare,

No, this is not what I was asking. Please refer to the original question.

Perhaps you may have something running in the background.

I notice that from time to time i have the same issue but this time i decide to see if i can find what was it...after looking and looking on the internet it seems that when there is a bunch of cpu load on system and systems interrupt is because some driver is causing problems. In my case I notice that if I disable the Realtek High Definition Audio the systems and systems interrupt becomes about .1% percent load which is what it is supposed to be...if I enable the driver back the systems and systems interrupt percent start to take a hit on the cpu.

I downloaded the latest realtek drivers from their website and the problem looks to be fixed....however it needs more testing on my side. If you have this issue and disabling and enabling the audio driver above fix the issue i recommend to download the latest driver from realtek and test it. If not it may be other driver that is causing the issue. The driver that im using is dated 5/14/2014 however in the website appears as 5/21/2014

http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=24&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false

You can download the driver at that link. If this driver doesn't work for you, you can roll back the driver

Hi Luigi,

The only solution I've found is unplug the usb for a while (1 minute, until the system interrupts process calms down) and conecting it again later. This is not happening all the time, so I can do it when it hapens 8·)
