When the Travel keyboard is not in use, the battery continues to deplete until it is in a state of deep discharge.
When the Travel keyboard reaches this states of deep discharge, the tablet is not able to determine the battery status of the keyboard. It does not show it in the BIOS under General and then Battery Information. It does not show it in the Windows Operating System, neither does it charge the keyboard battery.

Where the battery of your Travel keyboard dock has been completely drained of a charge (deep discharge), or has been depleted below 5% charge. Your tablet is unable to determine its battery status. For charging to occur, we require a minimal charge (5%) to be present on the battery.
Under the following conditions you must go through the steps in the next section before you can use plug and play with the keyboard: :
To resolve this:
Connect an AC adapter directly to the Micro-USB port in the hinge of the travel keyboard dock.
Leave it connected for at least for 20 to 30 minutes to ensure the battery charge is above 5%.
The travel keyboard battery fully charges using a direct connection to the Dell AC adapter in approximately 2 to 4 hours.
You are now able to connect the travel keyboard to your tablet with no issues.
