Question about HP iPAQ RX3715 Pocket PC
Unfortunately, I think you have a bigger problem.
1. In the interest of not costing you extra money, wait a few days to see if anyone has any last-ditch ideas.
2. Your battery is probably completely dead. Try purchasing a new one (Amazon.com is good).
DO NOT THROW AWAY THE OLD BATTERY!!! If the new battery still does not work, the old one has probably been shorted by the charger, but it might not have been, and you will now have two working batteries.
3. If that doesn't work, then like I said, you probably have a short in your charger. Refer to
For the solution.
You can try these solutions in either order, but this is the order i suggest.
