I tried a hair dryer and it now appears to be charging up at least from zero !Try it, you have nothing to lose. Mine recently died (wouldn't connect or charge) and the usual fixes didn't work. I read one place about using heat to help fix it. I used a hair dryer for a few minutes to warm up the pencil. I didn't get it hot, only slightly warm. I immediately connected it to my ipad and it connected right away. It then charged pretty quickly and has been good since then.
