My Surface Book 2 has let me down for the first time today.
It was working fine last I used it (2 days ago), but this morning, the Pen appears at least partly inoperative. The top button/eraser still seems to work, but the tip is not registered on screen and will not ink in any app (nor will it function to tap buttons, etc).
Fussing with unpairing/repairing the Pen in bluetooth settings, driver disable/reenable, reboots, enter UEFI and exit, etc... all the tips I've seen online... isn't helping. The Surface app and bluetooth settings still claim it has 85% battery left. Touchscreen still works with my finger. Surface Diagnostics app didn't find anything wrong (though it doesn't directly test the Pen itself).
I'm hoping despite the reported 85% battery in the Pen, it just needs a battery replacement. Will swap it when I get home. I also have a spare Pen which I'll try (thought I lost it on a business trip, bought another one, then found the one I lost).
If it's not the Pen's battery or the Pen itself, not sure what to do. If it's the screen digitizer, repairing the SB2 pretty much means replacing it and the Microsoft refurbished roulette I've read so much about doesn't sound like much fun. And the closest Microsoft store is about 2 hours away in Tyson's Corner, VA. Or I have to give it to my workplace's IT department to send in (which is worse than a 4 hour round trip to northern VA).
