[Q] Keyboard battery problem

[ChrisTheDBA]

Help! My keyboard battery seems hung. It won't discharge, it won't charge and it won't xfer power to the tablet. The other day I noticed that my keyboard battery was stuck at 55%. Odd. It fully charged the tablet however.

After doing some reading I tried draining the tablet with the keyboard attached. I got to 3% on the tablet, 54% on the keyboard. Again I charged the tablet and nothing has changed.

Question
1. Does this appear to be software or hardware?

2. If it's software can I flash the latest Cyanogen with having to reinstall or do I need to wipe the system

3. If it's hardware, can I replace the battery in the keyboard or is better to just order a new keyboard off Amazon?

Thanks

Just to clarify, the dock is still charging, but not updating? If so, that is most likely a software problem.

Are you using ASUS stock firmware or CyanogenMod custom ROM? Older versions of CyanogenMod (as well as some other custom ROMs) have known issue with keyboard dock battery charging and/or dock battery status report.

If your tablet is currently on a custom ROM, I would recommend flashing back the official stock ASUS firmware, just to test if the keyboard battery is still failing to charge your tablet.

As for alternative ROM, I would recommend trying CROMi-X (based on ASUS stock), Paranoid Android, AOKP, and etc... instead of CyanogenMod, as the official maintainers of CyanogenMod for TF300T have already abandoned Cyanogen and moved future developments to OmniROM.
