Surface Book 3 Throttling at 0.19 GHz

Also, the easy way to get to Power Options is to right click the battery icon and then select Power Options!  Not the messy way I described.

Hi,

No, what I'm talking about is found by going to Start Menu, Settings (the gear-shaped thing), System, Power & Sleep, Additional Settings (it's near the bottom, under Related Settings).  That should get you to Choose or Customize a Power Plan.  There you will see some options.  The first one is generally Balanced; the one you want is High Performance--that seems to do it.  I've seen it suggested that Best Performance after clicking the battery does the same thing, but for me it didn't.  The machine still throttled way down as the battery went down.

The funny thing is that I didn't always have the High Performance option, maybe because I had created a custom plan.  After I reset Windows, which re-installed it, and did a bunch of updates, my custom plan was gone and High Performance was there.  If you don't have it, Google "how to get high performance power plan windows 10" and you'll find lots of stuff.  The entry from help.ableton is very good, though I don't know who or what ableton is.  I'm going to do the suggested Regedit thing myself.

I hope this does it for you.  Let me know.

BTW,

--my machine still throttles down, but not to the dreaded 0.19GHz, and it always remains useable.

--I only did the reset at the suggestion of MS support.  They did not have a clue, and I don't think they even knew what throttling is.  The first suggestion to me was "remove your temporary files"!  Hopeless.

You mean, by adjusting the performance when, for example, you click on the battery icon and you set it to "Best Performance"?

I found a power plan called 'High Performance' on my Surface.  Changing to that, solved the problem--no more throttling down to 0.19Ghz.  Even with battery at 7%, it was still around 1 GHz.  I'm not sure yet what the effect will be on battery life.

Hi, so today I have been playing some games: Shadow of the Tomb Raider and Alien Isolation. There were no problems with the CPU throttling. In Shadow of the Tomb Raider, when I'm in the village with a lot of people, the game really slows down, but not due to CPU trhottling. Alien Isolation runs perfect.

I was also doing some Zoom videoconference, and sharing screens and audio with some friends. Then, the CPU started to throttle and it came down to 599MHz. I didn't even reach very high temperatures (max 89degC) and when the CPU was at 599Mhz the temperatures were not even 60degC. It's true that the computer didn't stay locked at that CPU speed and it came back to normal speeds. See image below with the tempertatures and CPU speeds.

Now, my question is: is this normal? Does it happen to you too? Is this an issue with the SB3, or is it a bad optimization of Zoom?

I highly doubt its a Zoom issue. I have .40 ghz throttling issues with my SB2 running Microsoft Outlook and Chrome web browser.
