It's easy to check and see if the date/time when you boot it up is way off. Then you know you have a dead internal battery.
I get it now, and yes the clock has been way wrong in the recent past when starting up....
Off to google internal battery replacement. I'll update once I get this done and test.
Thanks for posting!
