Hi everyone,
I was wondering if anyone has a solution to the 0.40 GHz throttling problem that was supposedly solved about a year ago.
My CPU speed goes down to 0.4 GHz unless I have it plugged as shown in this video:

Clearly, many people are having this problem, even when they exchange their devices their new devices had the same issue, but Microsoft agents have no solution other than canned responses that don't help with anything. They just blame your device and make you run a bunch of diagnostics to make you give up instead of finding a solution.
I wasted my time trying all the solutions I found online, here are the solutions that didn't work:
Non-solution 1: "It is a firmware issue that Microsoft fixed with an update (according to this Microsoft agent and many others)".
My SB2 is up to date on Windows updates. I have installed updated drivers and firmware here and manually forced everything in the device manager to check for updated drivers from those folders.
Non-solution 2: "It is a thermal issue".
No, it is not. See my temps below. Besides, if it was, it wouldn't throttle up when I plug it and down when I unplug it immediately.
Non-solution 3: "It is a battery-saving feature, put it on Best performance" (according to a Microsoft agent).
No, it is not. See the medium battery level and performance mode with the 0.40 GHz clock speed on the screenshot below.
Non-solution 4: "It is an issue with the dedicated GPU driver. Microsoft fixed it."
No, it is not. My SB2 is the base version without the dedicated GPU, the specs are below. Many other people with dedicated GPUs have been having similar issues but those are/were a separate issue and can't be applicable to mine.
Non-solution 5: "Use the System File Checker" (according to a Microsoft agent).
No, it still happens after doing that.
Non-solution 6: "Run the Surface Diagnostic Toolkit." (according to a Microsoft agent).
Non-solution 7: I formatted and reinstalled Windows 10 and it didn't help.
Am I missing something obvious or are we sold an overpriced laptop that doesn't work without a power cord?
Thank you in advance for any advice.
