S2218 notebook Date not retained

[Goldflipflop]

For my S2218 notebook the Date/TIme is not retained after power off.     Does this machine have a replaceable CMOS battery?    If not, any suggestions for solving this?

Hi @Goldflipflop and welcome

According to this German contribution, she has a CMOS battery

Thank you to Fishtown for the pointer to another contribution.

My S2218 had been without power for about 6 months. I think the main battery was completely empty.  After the machine had received some charge it was able to run. It started with a default date. After a short run with network connection it received network time.  The S2218 realtime clock was then correct.  After a power down and restart the Date and TIme started correctly without any network update.   Problem gone away!

I think this means the Realtime clock is supported by the Main battery possibly indirectly via a rechargeable motherboard battery.
