Surface Book 2 throttles excessively, often down to 0.4 GHz

I've recently purchased a 15" Surface Book 2.

When compiling large projects in Visual Studio 2017, I find that the processor often throttles excessively, often down to 0.4 GHz. As a result, compilation takes several times longer than it does on my 5 year old MacBook Pro. 

The Core Temp app shows that the CPU at this point is at 50-55 degrees Celcius or so.

The following question touched upon this problem, but the proposed solution did not work for me:

Any ideas on how to fix this?

Thanks.

    Hi,

    This has been happening to me mid workstream and driving me up the wall. This is normally within my AC controlled office so no issue with temps. I'm using a SP6.

    Iv managed to confirm that this only seems to happen when I am using one of the older power bricks in a clients office. Whenever I connect the power supply the CPU immediately locks to 0.4ghz. The CPU in all of my power profiles are set to 100% for either battery or connected to power

    as soon as I unplug it the CPU shoots back up to normal. When I use the power brick that came with my SP6 and or a surface dock there is no issue.

    Iv gone through the support process with MS and they just keep asking me wipe and reimage my machine. I am very loathe to do this as this is my work machine and will take the whole day or two to get my software back on and sharepoint/dropbox all resynced.

    I'm trying to keep it going until hopefully a fix comes out.

    Regards

    try the second one. The first solution ceased to work somewhen, yet with the second solution, I've never met the problem anymore!

    Thank you for the response Zhan! I'll try it out! I had to replace my Surface Book because of unrelated issues with the base. In my experience this issue pops up a couple of weeks to a couple of months in to ownership. I agree with you that it seems to correlate with ambient temps though neither the processor nor the graphics card near the temps needed for thermal-throttling. If/as soon as it pops up I will let you know my results!

    All the best
