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.

    Just two items in the one year long Microsoft Surface Pro 3 CPU bug which can make this tablet unusable without the power supply:

    The only reliable way I have found to deal with this system software bug in the interim is to play music using the music app, put it an infinite loop, and mute the sound.

    To truly fix the problem, the press is going to need to be involved to raise the issue higher up the chain and raise the possibility that sales will be jeopardized.  

    The New York Times, and Wall Street Journal both have computing/technology sections and might be interested in this issue as an investigative journalism piece showing how a large tech company that's literally deaf to the problems experienced by their users. 

    Media, if a search engine has made this problem visible to you, please help!  Users, please forward this issue to your favorite investigative journalists!

    I have the same issue too. SYSTEM is around the 25-30 of high CPU. With Process Explorer we couldn't find anything related. We tried to reinstall the High Definition Audio Driver, but without hope.
