Hi. I have a brand new, i7 256 Surface Book 2 with an annoying problem. The trackpad and keyboard both exhibit huge lag when running on battery power, with anything less than "Better Performance". Even then, it's not perfect unless you go for the 'Best Performance' setting.
When running in battery mode, it's easy to appreciate that more people might be using the trackpad rather than a mouse (for portability) so why this won't function properly on the lower power saving modes, is confusing to say the least. One would expect the keyboard to work cum-what-may.
I've never experienced this issue with my Surface Pros and feel rather disappointed given the cost or the Book 2.
Any fixes please, other than disabling the two-finger pinch to zoom function?

One thing that is significantly different on my machine vs the average user's Surface Book 2 is that I use Hyper-V a lot. The Hyper-V role changes the structure of the OS pretty significantly.
Is everyone else running Hyper-V? Is it possible that this is actually a Hyper-V problem?

Neither of the SB2s that I'm using right now have Hyper-V installed, and both experience the issue.

Anecdotally, seems a bit better lately but it's erratic... Sometimes working OK but usually still with lag. On low power use, keyboard lags too and it's not just the track pad but a Bluetooth connected mouse as well. It's just not good enough for this type of machine at this price point.
@Microsoft, please advise and issue a fix. Never had this issue on my SP4 so don't expect it on a laptop costing twice as much.
I agree. This issue predates the meltdown/spectre stuff. I've had this problem from the moment I lifted the SB2 out of the box.
Definitely not related to the Meltdown/Spectre mitigations...
I got my SB2 15" on 11/16 and this issue was there day 1. Others online have also seen this well before the shinanigans recently.
I suppose it's possible that I only started noticing the lag, so I won't dispute that. The bottom line remains that it's a huge issue and Microsoft neds to address it.
I took back what I wrote earlier. On battery, it's not just as bad as before I disabled the Metldown/Spectre mitigation.
