Simultaneously turn on the uninterruptible power supply and desktop computer.

[grigtar]

Good afternoon!
I will be very grateful for your help !!!

I have  HP 690-0000NJ Gaming Desktop PC. Windows 11.I have a desktop connected to an uninterruptible power supply. When I'm not using my computer, I turn off the UPS by pressing the on/off button on the UPS.
Before I want to turn on the computer, I first press the on / off button of the uninterruptible power supply and I turn on both the uninterruptible power supply and the computer at the same time.
Attached a screenshot

This problem did not exist before. At first I turned on the UPS, and then I pressed separately, pressed the power button on the computer itself.
What can you recommend to solve this problem?

(So ​​that when you press the on-off button of the UPS, the computer itself does not turn on).
Thank you very much for your help !

@grigtar,

My first observation is to never turn your UPS off.  I have several UPS units online, and they usually last a couple of years -turned on 24/7.

Turning your UPS off and on will shorten the life expectancy of its battery.

Every night, with your UPS unplugged, the battery self-discharges. Every day, when you plug the UPS back in, the battery has to charge back up to compensate for the self-discharge. This daily partial discharge, full charge cycle will reduce the battery life.

Thank you!

But I have a question:
How to prevent the computer from turning on when you turn on the uninterruptible power supply?

@grigtar,

You have to check if your computer is in hibernation/sleep mode, and not in full shut-down mode -which is preferable in my opinion: https://support.microsoft.com/en-us/windows/shut-down-sleep-or-hibernate-your-pc-2941d165-7d0a-a5e8-....

Again, leave your UPS on.

@grigtar,

Btw, when you keep turning your UPS off and on, in exchange for said reduction in battery life, you may prolong the life of certain non-replaceable parts of your UPS. However, these parts rarely fail.

Perhaps you turn your UPS off to save energy/reduce your carbon footprint.  A lofty goal, for sure.

However, you will see increased electricity consumption whenever you turn your UPS back on.  A line-interactive UPS doesn't have much of its internal parts on when the input power is normal and the battery is fully charged -UPS energy consumption is minimal just to keep the battery charged.

Hope this was helpful.

Kind Regards,

good morning
just for information because, I have not seen mention of this despite several messages / response
So the problem indicated, could well correspond to what is mentioned here

https://support.hp.com/us-en/document/ish_4209641-3226345-16

Personally I would do a test without the device, computer connected directly to the power supply, and check if still the same problem

and check motheboard Battery

Thank you for your letter!
I have checked:
I connected the cord from the computer's power supply directly to the outlet and the computer turned on by itself
THANK YOU VERY MUCH FOR YOUR HELP!

I just wanted to share this HP document
now I'll leave you with @NonSequitur777  for the rest
But just one thing, if computer boots when plugged in, check options in bios, something like "boot after power loss", disable
Good luck
@NonSequitur777  I'll let you continue..
