SB randomly stuck on low CPU frequency

[kltye]

So I'm having the opposite problem of the CPU scaling problem, where the CPU is stuck at its highest turbo frequency - mine randomly gets stuck on low frequencies, <700 MHz, no matter the CPU load. This seemed to happen after the last firmware update, which was to fix the stuck-at-turbo-speeds-all-the-time issue. This is annoying because apps randomly slow down, and multitasking becomes a real chore.

I've tried enabling and disabling SpeedShift from the control panel applet, and I've also tweaked the autonomous mode preference policy to 0% to try to force the CPU to turbo. It randomly happens, so after a period of time, it works at its usual speed (>1.5 GHz during regular usage).

Anyone else have a similar issue?

Did you get any resolution to this?

Nope, still facing this issue. I disabled Connected Standby (or Instant Go, or whatever it's called now), but the problem persists. Are you having the same problem as well?

I don't have the device actually but wanted to see if there was any update - have you tried contacting MS support? They can be helpful sometimes

It seems that I have the same issue. Everything - from file system manager to even typing the text - becomes to work very slow, and the CPU frequency is of order of < 1 GHz. This is the real issue for me, since for avoiding such problem I have to restart Surface Book.

I've got the same issue after latest firmware update JAN 2017.

My new Surface Book also has the same issue. I've noticed that in most cases the problem occurs when running Edge web browser. The frequency becomes normal when closing it. But since the Edge browser is very convenient for touch using, it is crucial for me to find the solution for this problem.

I am also having issues with the CPU running at a low frequency for no reason. This notebook has become so laggy.
