Barb: Thanks so much for all the helpful instructions on fixing the issues I was having with my Surface Pen & for the wealth of info you'd provided on the different versions of the Surface Pens that have been released since I'd purchased my Surface Book- it's all very useful & therefore highly appreciated!
While replacing the AAAA battery, then pairing my Surface Pen's Bluetooth connection to my Surface Book again after doing a "hard reset" (pressing both power & volume +/- buttons in tandem) resolved the
issue temporarily, within hours of doing so, I was once again experiencing the same problem- with the top button being functional, but the stylus point once again becoming entirely nonfunctional.
I have since stopped/restarted the Intel Precise Touch Device service via the device manager interface as you'd so kindly described how to do step-by-step in your reply & so far since doing that, after
having put in that new AAAA battery previously, the pen has been working perfectly once again.
I do have the Fall Creator's update installed + every other available Win10/Driver/Security update released since then on my Surface Book (also have all newest updates on 2 other, older PC's w/o touchscreens), however, I utilize Microsoft's Windows 10 Update
App w/ each boot of my SB instead of checking for new/available updates via the update module within the settings user interface- either manually, or by relying on the OS to auto-update itself... I decided to use the Win10 Update App on my SB in place of
relying on Windows Settings to install the newest, fully-tested/commercially-ready Win10 updates because my online research indicated that short of joining The Window's Insiders Program (which I do take part in for use with both of my older PC's using a personal
M-soft account), that using the Win10 Update App would get me the newest updates for my SB as fast as they're publically available. I'm reluctant to join The Windows Insiders Program on my Surface Book because it serves both as my primary business
& primary recreational PC/tablet, so I cannot afford any systemic instability which could possibly result from installing a newly-developed Insider's update on it.
Given that fact, I almost always use a Microsoft Work Account to log in
on my Surface Book/M-soft products on the SB (I own a Small Biz so I have both a personal & a separate, work-related
Microsoft account which I use), as my work account is not
enrolled in the Windows Insider's program- the aim of that being to only download fully-vetted/stable updates which (hopefully) wouldn't lead to any serious instability on my SB serving as my primary machine these days... It seems that
by having downloaded & then regularly running the Win10 update app from Microsoft on my SB using the Microsoft work account not enrolled in the Insider's Program, that instead of relying on auto-updates or manual updates via Win10's settings, this method
continues to be the best method to obtain all the newest, yet (hopefully almost) entirely stable updates as soon as they're publically available.
As far as I could tell, before fixing the pen as described above,
I was not experiencing any pinch-initiated/related zoom issues, whether via touchscreen or trackpad input- in fact, all touch input was working perfectly as long as it wasn't via the pen. While I am unsure if that's a significant factor or not, given
this issue seems to be a widespread problem for those with the Fall Creator's Updates on their Surfaces/Surface Books, I wanted to provide as much info as possible on the nature of my problem, the steps I'd taken to remedy it & what fixes actually worked for
it- both temporarily & more permenantly (as appears to be the case now), because I had neglected to send any feedback to Microsoft before applying the fix you'd recommended, so I'd assume that any data sent at this point (after having fixed the issue) would
not reflect my system's status at the time I was having problems with my pen.
Since applying the suggested fix, all is running well once more, SO
AGAIN, THANKS FOR YOUR HELP BARB!
