After you removed the RTC (Real Time Clock - aka CMOS) battery did you power refresh the laptop at all? (I assume when you say the “motherboard battery” that this is the one you meant).

Try the following:

If not, try the following:
Disconnect the charger if connected.
Remove the main battery from the laptop.
Remove the RTC battery from the motherboard.
''Press and hold'' the laptop’s power button operated for a ''full 30 seconds'' and then release it.
Reinsert the RTC battery, reassemble the laptop, reinsert the main battery and connect the charger.
Try to turn on the laptop. If it turns on there ''may'' be a message that the Date and Time are incorrect. This is normal as the BIOS has been reset by the removal of the RTC battery and the Power refresh. Once it has been corrected, the message won’t appear the next time that the laptop is started.
What voltage did you measure on the RTC battery? If it was <2.5V replace it.
