Hi, Lynne here again about computer changing time/date. My computer was changing the date to July 4 and even August 15 2018, not “0”. It did not change the time.

No, we don’t suggest you to replace the battery. It seems like your CMOS battery is OK if the date & time doesn’t reset to zero (12:00). If your computer keeps changing the time instead of reset to 12:00, it seems like a software issue. Yes, the option “set date time automatically” could be the root cause of this problem.
