I have had my Axim since March 2003 but this is only my second day at this website. Someone else has the same problem and posted their thread in the main X5 forum area. Here is what I wrote in that thread:
I started having that problem back in December. I replaced the backup battery and a few days later I would get the warning that it was at 0%. Then the next day it would be back at 100%. Unfortunately on one of the days that it was at 0%, I removed the main battery and I lost all of my information so, as a warning, do backups regularly.
The next thing that you may start to notice (if it hasn't started to happen already) is that your touch screen doesn't respond correctly. I would tap the OK in the top right hand corner of the screen to close a window and the keypad menu at the bottom right hand corner would pop up. I would have to play around with it for a while before it would work right again.
I never seemed to have the time to check this problem out so, after a few months of this, I found myself (on more then one occasion) tempted to throw my Axim at a wall. It wasn't until just 2 weeks ago that I did a search on the internet and found out what the problem was (half way down the page of this URL read, "QUOTE DELL USER MARKINS".

There is a flex cable that connects the touchscreen to the motherboard and it may be starting to short out like mine was. I followed the instructions on the website and now my Axim works just like it did on the first day that I bought it. No more low backup battery warnings and the touchscreen works great.
