Today, I found my Windows 10 date and time too far ahead by about 26.5 hours. The time zone is fine, and I corrected the problem by clicking on a "Sync" button to sync with a Microsoft server.
Googling indicates that the problem might be caused by a dying CMOS battery. This page describes a number of ways to check the BIOS battery from "System Information". I don't see any of the things described, including:
- A "Batteries" entry under "Components"
- A BIOS section under "System Information"
- A "Battery" section under "System Information"
Below, I capture a screen shot of what I actually see instead.
My next step is to reboot and go into the BIOS, but I really don't like doing that because it is a very foreign environment in which I can mess things up.
Can the CMOS battery actually be checked when Windows 10 is operating, or is this old functionality that has been removed from modern versions of Windows 10?
