HP Ipaq 4155 not recognizing battery

I have an HP Ipaq 4155 and after a major battery drain I thought the battery was dead. I orderd a replacement battery, installed it, and charged it for the required amount of time turned it on and instantly got the "battery low" message. I charged it again and received the same error. I found my old cradle and took the battery out and charged just the battery and it charged fully. Installed the battery in the ipaq and still received the "battery low" message even though I know that the battery is indeed charged.

So, to summarize, here is the issue:

My Ipaq is not recognizing its battery at all and "thinks" it is always on system battery. My ipaq also may not be charging batteries but I can't say for certain because it doesn't see the battery.

Things I have tried without success of resolving the issue:
Manually charging just the battery in a cradle.
Resetting the Ipaq.
Reinstalling the latest bios.
