Mouse freeze on surface book 2 after the most recent firmware UEFI version 389.2268.769.0 update!!! especially when power adapter plugged in

Thank you sir!  I have done all the other fixes (first noticing that as long as I kept mouse polling below 500 it was fine), then with a few of the update fixes, it was fine at 500, but still would occasionally freeze at "Best Performance".  Doing the fix in the Reddit post finally solved my problem.

As the post mentioned, it seems Microsoft added a little too much overclocking to the processor.  As with all processors, some can overclock more than others depending on luck of the draw.  The person at work that has the identical Surface Book 2 as me has never had this issue even though he has updated his with all the latest updates, while mine was fine until the update that introduced the issue.

i have yet to see for myself or hear of a case where MS took feedback from feedback hub, realized there is a problem, investigated, and fixed it. i have submitted several critical issues. heck, i had a non-functioning power button for eight months and still having wifi issues. why waste time submitting if they dont do anything with the reports?

I've been watching this thread for a while and asked an internal contact to look into it. He has responded as follows:

"

I was able to reproduce this issue although not as easily as some say.  I have been running tracing and working with Windows engineering.  The best thing I can recommend that is customers report this issue via feedback hub.  Choose the input and language\mouse and include data about “Performance”.  Uncheck the screenshots of each step.

"

I would urge everyone to use the Feedback Hub and file this report and share the feedback and post a link here.

Thank you for the reply.

Jump to the conclusion first: I can 100% confirm that it is the issue caused by the UEFI firmware or the aggregator firmware, the reason was that:

1. I have eliminated all the other factors which may causing this issue, including resetting/restoring the system, clean installation, update any software/driver available etc...
2. the problem was never there before the firmware update.
3. all the mice tested have no problem at all on any other desktop/laptop except the surface book 2 with the 389 version firmware
4. the other (second one) surface book 2 with the 388.1932.769.0 firmware had no problem but problem started to appear immediately right after the firmware updated to 389.2268.769.0 and aggregator firmware updated. 

So the issue here is that I cannot revert back to the 388 version firmware anymore if there is no update provided by Microsoft. 

Speaking about the issue itself, yes G703 mouse is a gaming mouse. Switching to the other Microsoft touch explorer mouse made the freeze/lag frequency lower but it still happens.  When using the wireless mode of the G703, the mouse freeze/lag at random manner and frequency. But when using the wired mode (connecting to the surface book 2 using the usb cord), the mouse will totally freeze after a while even though the LED on the mouse is still on (meaning that the mouse is still physically connected but just not working).

Adjusting the power option from "recommended" to "better performance" make the problem worse, and "best performance" basically kills the mouse as it will freeze/lag almost every second.

At the moment,  such update makes the device to be very hard to use. I hope there is a way to revert the firmware back to 388 version as this is the fastest way to solve the problem. (as a matter of fact, the latest driver package downloaded from Microsoft now has the 388 version included, not 389 anymore, even though 389 is still mentioned on the update history page).

Hello skytulip33,

Thank you for bringing this up. There are some factors affecting the performance of your mouse on the Surface Book 2 like current OS version, hardware compatibility, updates that are not yet installed, etc. However, to be able to understand the issue better, let us know more details by answering the following questions:

• Were there any other changes made to your Surface aside from the firmware update?

• Can you confirm if those mice are gaming mouse? Did you check if those mice have any softwares/firmwares/drivers installed on your Surface? If so, is it updated as well?

• As for the Microsoft wireless mouse you include, which model? Did you check for the LED status (if available)? How about the battery?

• Also, we would like to know if the issue is noticeable while using it, or after you wake the device from sleep?

To help solve this issue, we'd like to make sure that the Surface is up to date by going to Settings > Update & security > Windows Update then Select Check for updates (Select "Restart now" if prompted). If you have difficulty installing updates from Windows Update, you can download and run the Surface Diagnostic Toolkit. It is a self-healing tool which looks for potential issues and fixes them, as well as ensures your device is completely up to date. The tool takes about 10-15 minutes to run. You can click this link to get started then follow the on-screen instructions.

To troubleshoot the Microsoft wireless mouse, we suggest that you check these steps:

1. Unpair then re-pair the mouse.
2. Run the Bluetooth Troubleshooter by going to Settings > Update & Security > Troubleshoot. In the list of available troubleshooters, select Bluetooth then click "Run the troubleshooter". Follow on-screen instructions.
3. If that doesn't work, proceed to download and run the Surface Diagnostic Toolkit.
4. In case that the wireless mouse have no power left, replace the battery. If it's rechargeable, plug in to the device via USB cable.

Keep us posted on the outcome.
