Well, I performed a hard reset of the x50v.
After about three weeks of no issues, the problem has surfaced again. Whatever is happening

, I can say that it seems to go into a mode where the battery is being drained. I can tell because it gets warm and even though I have not used it (I can't see anything on the screen when I try to turn it on), it will need a recharge.
I'm looking for any advice. It is rather annoying to have it go into this mode and need to rebuild from scratch. Admittedly, I don't have much extras on there, but I rely on what is there.
See details in former threads for content of machine.
BTW, I've checked for the usual suspects, like the lock button being accidentally turned on, or the battery door not being locked. Oh, can't do the 'fake server' trick on WM 2003 SE either.
I'm at a loss (and of course the Axim is out of warranty).
