My 1st generation Apple pencil won't write. It's weird. I left it for a few weeks and when I picked it up it was dead, so I charged it up and paired the thing with the 10.5 iPad Pro it came with. It pairs fine, shows up in iOS and Bluetooth, but when I write on the screen I get nothing. I've tried rebooting the iPad, trying it on another iPad Pro where it also pairs but does not write. Also tried swapping the pencil tip and still nothing... I took it to the Apple store and they wouldn't even try to diagnose it. They just offered to sell me a refurb for $79 (vs. $99 for a new one with warranty) so I walked out. It's considered a disposable item by Apple, so they don't do anything. Does anyone have any suggestions for what I could do or is this pencil RIP?
