Good question. Never thought about it. Doesn’t it just get time from internet (NTP) or are you off line?  Tell us if it works.

Well, yes my Windows 10 is set to get the time and date automatically and it does. However on bootup I have Windows set up to connect to my home network for internet access, load ARC and and run my INT script automatically. When I boot, windows still reports the time and date of the last shutdown of the SBC because there is no CMOS power provided to keep it active. My setup of Windows 10 seems to check the time and date and make the adjustment well after ARC starts up. Thus ARC says there is a system clock issue and wont start.

I'm getting the Cmos battery today so this should solve this issue.

OK, I got the COMS battery installed. It solved my system time problem completely and ARC starts after a successful OS boot.

However a new problem has popped up because of the battery install. UGH! No good deed is ever gone unpunished. LOL.

Before the battery install the Rock Pi X used to boot up into Windows right away when power was applied to the SBC. Now that I have a COMS battery attached as soon as I power up the SCB it flashes a bright blue LRD and stops booting with a dim blue and green LED. Now to boot up into Win 10 I have to push the Rock Pi x's power button. I've contacted Support and checked in with the forum and there seems to be no way to change this behavior. No setting in the bios that I can find that will change this.  Support got back to me in a very short time and suggested to reload the bios default values. This didn't work.

This is an imbedded SCB in a place of the robot that is hard to access. I won't be able to (and don't want) to push the SBC power button each time I turn on the robot. Unless there is a solution to an automatic boot into Win at SBC power up I need to figure something else. I'm thinking I can wire into the RTC port on the back of the Rock Pi X, extend the wires to a time delayed relay that will close at power up and then release a few seconds after the SBC starts to boot. I still need to find something or learn how to build a switch or circuit like this.

One thing I'll need above else when I find a time delay switch is to find the proper connector that will plug into the Rock Pi x's external power button port. The CMOS battery I mentioned above did not have the proper connector. I had to steal one from a different accessory that I had that did fit and splice and solder it onto the battery wires. Now I need another one for the power button.

Does anyone know where I can find a connector that will fit the little ports on the Rock Pi X? They call the connector a XH1.25mm. Ideally I guess I could get a battery like I show in post #1 above and cut the wires and use that.

Also if anyone has an idea of where I can get a time delayed switch or circuit relay I can use on the start button I'd welcome the help. I'm going to start digging and asking around now.

Any other ideas are welcome.

maybe you should just ditch the battery and put a timer in to wait until Windows has the time from the internet before it starts ARC using task scheduler

Thant's a thought. I'll try it to see what happens. The only thing I don't like is this will make the load time longer until my robot is operable. Well see if there is a huge difference.

Is this what you are looking for?

Sorry the link was to Australia?

Yes. That's them! Thanks. Now I just need to find them in in the USA. LOL.
