Time & Date won't sync on start-up

Hi
Since the big win 10 update last month I've been having trouble with time & date, it just won't sync anymore on start-up.I did google and it led me to the check service and change to automatic from manual, still doesn't help.When using laptop and I do the time manual it keeps correct while I'm on, but when I shut down and come back the next day the date & time are from the last time I was on laptop.
Thanks for any help on steps to fix
Also tried w32tm /resync

Win 10 Home
Ver 20H2
x64

It might be the CMOS [ Complementary Metal-Oxide-Semiconductor ] battery, which is basically a small amount of memory held on the computers motherboard that stores the BIOS settings, one of which is the Date & Time. They are relatively cheap to replace.

I hope this helps.

I will pick up a new battery and give it a try, would be nice if its that easy to fix.
Thanks.

I know. That would be my initial diagnosis. Please let us know how it goes.

Jack,

I have never seen any relationship between Startup & TimeSync - I monitor both in the Event viewer and TimeSync just seems to happen when it feels like it.

So I think your problem boils down to

- Does this problem happen even if you remain connected to AC power during the interval?
- Is your main laptop battery decently charged during the interval?
