Clock is Bad - Replace PROM battery?
My clock is not keeping time when the laptop is off or in standby. I suspect a failing PROM battery. How do you replace a PROM battery in a 2015 13'“ MacBook Pro?

There is no backup battery as Apple dropped it once they went to a sealed system. An iMac still uses a PRAM/NVRAM coin cell battery.

I’m suspecting the one and only battery your system has is failing or defective as it has a trickle feed for the NVRAM logic so its settings aren’t lost.
