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.

Sleep mode is a reduced power consumption mode that turns off the user interface while the rest of the device "sleeps".

When "asleep" a Windows 8 / 8.1 tablet will still poll WiFi connections and do some background processes.

My Surface Pro 2 seems to have daily updates. It quickly empties my data download quota on a 3G connection (via WiFi router). Had to change the Settings to prevent it downloading updates when on 3G.

The only way to stop my Surface Pro 2 from doing anything is to Shut down when not needed and is being carried. I only use Sleep when it is connected to the mains power and is sitting on a desk.

Shut down with a Surface Pro is similar to the old Hibernate on earlier versions of Windows in that it saves current configurations to a file so that it rapid boots when switch back on. It is very quick to boot up from a Shut down state.

So: Do not use Sleep when the Surface is bagged and being carried. Use Shut down instead.

In a way, it is by design; it is not a defect.

Should also note that before the Surface Pro 2, I owned an ASUS Smart Tab tablet that I upgraded from Windows 8 to 8.1. It showed the same battery drain on sleep that the Surface has. It would go flat in about 3 days if left to sleep alone.

So, I have the same problem with my Surface Pro 3, I7, 256GB.

Processe System Interrupts are using about 8-9% of processor usage.

In idle situation, my machine is using around 25% total CPU ...... it's insane.

If I disable the Realtek audio driver it seem to solve my problem.

My CPU returns to 2-4% of total CPU usage.

So, cleary it's related with Realtek Audio driver,

Microsoft please solve this probelm.

Thanks!
