I am using a remote switch to cycle system power. What bios setting would allow me to cycle power and not shut down after ten seconds?]]> Wed, 12 Feb 2020 19:14:07 +0000 https://forum.asrock.com/forum_posts.asp?TID=7512&PID=72753&title=turning-on-then-off-by-itself-when-powered#72753 <![CDATA[Turning On Then Off By Itself When Powered : To prevent the computer from turning...]]> https://forum.asrock.com/forum_posts.asp?TID=7512&PID=65823&title=turning-on-then-off-by-itself-when-powered#65823 Author: rocky

To prevent the computer from turning off, I'm letting the capacitors charge before turning on the computer.

I usually turned the computer on after the UPS is done performing its self-test, which only takes a few seconds.]]> Tue, 30 Jul 2019 20:25:42 +0000 https://forum.asrock.com/forum_posts.asp?TID=7512&PID=65823&title=turning-on-then-off-by-itself-when-powered#65823 <![CDATA[Turning On Then Off By Itself When Powered : Glad to know I don&#039;t have...]]> https://forum.asrock.com/forum_posts.asp?TID=7512&PID=44259&title=turning-on-then-off-by-itself-when-powered#44259 Author: rocky

Glad to know I don't have to remove the UPS, or anything. Smile

Have you noticed if the entire system starts the boot process, like the hard drive reading because it seems to stop abruptly?

Would be nice to have a feature like this mentioned in the manual, I thought I was going to have to disassemble the whole thing.

This is by design, when the capacitors discharge completely the "issue" will occur. It isn't anything to worry about, merely the board charging up it's capacitors in readiness for power on. This process reduces power spiking when the system is powered on and off and will increase the lifespan of your board. I would only be concerned if the system powered on with the UPS and remained on. My system does the same thing (X370 Taichi + R5 1600x) when I leave it unplugged for more than a few hours, I think there is a voltage threshold for this to trigger and it would seem that UPSes often cause this, it is just a safety feature doing it's job Wink

Enjoy your new build.

Replaced the CMOS battery and cleared the CMOS with jumper, but the problem continues.

If I turn off the UPS and wait some minutes when I turn on the UPS the PC turns on, too. The UPS continues with its checkups and the PC turns off. ]]> Wed, 31 Jan 2018 04:41:57 +0000 https://forum.asrock.com/forum_posts.asp?TID=7512&PID=44251&title=turning-on-then-off-by-itself-when-powered#44251 <![CDATA[Turning On Then Off By Itself When Powered : A recently built machine turns...]]> https://forum.asrock.com/forum_posts.asp?TID=7512&PID=44229&title=turning-on-then-off-by-itself-when-powered#44229 Author: rocky

A recently built machine turns on by itself when UPS is turned on (starting the day) then turns off after a few seconds.

After pressing the power button it turns on and works as expected.

In BIOS it is set to not turn on when powered (default).

There is no video card.

EDIT: Turning the UPS off and on doesn't cause the problem, but leaving the UPS turned off overnight seems to cause the problem (suspecting a faulty CMOS battery).
