[FireSale]

This has happened to me on older computers. There is a separate dime sized battery that is responsible for charging the memory that keeps the date. If you have the nerve and a set of small screwdrivers, take the back off and look for a small removable battery. The one in my computer was a watch style one. Check the number on it first (if it's there) and check availability of a replacement before trying to remove/replace it. Some are soldered in.


Good luck.
