I did not see a reference to an internal battery but I would look on the motherboard for that and check it's voltage.

T.

There is no internal battery on the main pcb. Its prettry simple internally.   appears to get its power for the rechargable lead acid battery. That has been changed a few months ago. tested the battery this morning and it is fine. Load tested and I have an awesome battery tester.

Firmware versions are there newer version currently on 1.21.00

I am thinking is a pcb issue.

Everything else is working though?  I would call Mortara (Hillrom) before I replaced the board.  Might save you some bucks.
