I had this setup all nicely in Windows 10. After being forced to update to Windows 11, ive noticed my PC does not power up after it loses its power and the power is restored to the house. I cant really find anything online or anything in the BIOS settings. Can anyone help me out here?
Windows 11 - Powerup after Losing Power?

It is missing in Win11, It is a feature that is really from the Bois anyway. What Motherboard are you working with?
Going into your Bios, Might be under Advanced and would want to find something that has info about what to do after a power loss. Something like Power On, Enabled or Last State..

OK actually interesting enough....i found it does restart after power loss. I just tested it. However, i have it on a UPS and when the UPS battery is drained and then the power is placed back on afterwards....it wont restart. Im not sure how this makes sense though
Ok, For others, Here is a picture of my Bios, you can see it is setup in the Advanced and advanced area.. If you have a search do a search for power and should take you to the area you need..
@jelf4352 yeah if it is setup in your bios to restore power it will. However after your UPS goes offline some UPS are setup to not restore power to the outlets without that being enabled? If your UPS has that feature then it might need to be enabled. I know there are some out there that have a Serial connection that can be linked to send a pulse to the computer looking for it to have power restored.. If you don't have a Cold Start type UPS may need to upgrade to one..

No that one should have it. I would look to see if it is in the manual about how to enable if it came disabled by default. Might be a safety feature disabled..
Do you have the APC backup connected to your BI PC with the supplied interface cable, if not then it may not shut down gracefully and may not come back on when the power is restored, I have several APC backup units and all of them come back on after a power failure event!
Ok so I’ve tested out the UPS issue. After the battery has drained and power is restored, the PC actually powers back on. However, it shortly turns off. Is this because the battery is drained on the UPS and it’s telling the pc turn off because the battery is low? I don’t think I can change these settings . I am waiting to see if the PC will power on after the battery has fully charged.
There are some setting in the APC software that allow you to change how low the UPS battery will get before it preforms a shutdown!
I also noticed on the APC web site that that model was marked end of life in 2022, is it possible that the batteries in your UPS are just too old?
Is there a date of manufacture on the UPS, that might give you some idea what the actual age of the batteries are?
When the UPS is fully charged the display should give you the current load and an estimated run time number. you can test how long it will run by pulling the UPS plug and see if it lasts as long as the estimated run time!

Yes the settings say that it will turn off pc when battery is 5 minutes left. I did a test….it says 50 minutes but only gets around 25 minutes. Had the battery a couple of years so probably time for a replacement.
Should I just replace the battery or get a new ups? Even with a new battery, the settings say it will turn off a PC when theres only 5 minutes of battery left. So I feel like replacing the battery won’t really resolve the issue

If the UPS is only running half of the estimated run time, I would recommend replacing the batteries. As far as replace batteries or a new UPS, you should do some research on how to replace the batteries, as then are usually in a sort of battery pack which has to be taken apart and reassembled, not a difficult job if you are a bit handy! Replacing the batteries should be much cheaper than a new UPS, at least it used to be before the tariffs, but since both the batteries and the UPS are possibly made in China I have no idea!
I had the BR1500MS on my BI Server since I set it up back in May 2019. It always powers back up after an outage and the UPS batteries get drained. It finally crapped the bed back in February and I replaced it with a BN1500M2.
I do have three more BN1500M2 units that power the modem, some POE switches, and a NAS. They also come back on after a power outage and the batteries are drained. Had to replace one battery pack in July 2023 on one bought in September 2018.

I recently had a couple of CyberPower UPSes that did not restore output power after the input power was restored. Turns out if the battery is dead the UPS will not deliver power even with input power. Restart the UPS and everything is fine until the next power outage. Worse than useless.
My fault for not testing them. They were hidden away in closets or the garage and not connected to a computer. I had no easy way to run the selftest . Even after connecting to a laptop computer the PowerPanel software did not indicate any battery problems. Future plan is to unplug each UPS and time it until the battery drains and the UPS shuts down. I will then restore power and make sure power is restored.
I replaced one of the CyberPower units with a UPS from APC. After setting it up to power my Mac computer I discovered that their software does not run on MacOS. I may switch it to my Blue Iris PC. Or not.
The next UPS passed the selftest by the battery capacity dropped from 100% to 20%. Next selftest dropped it to 7%. Did not see the need for a third selftest. Replaced with OEM battery and it works fine now.
For the third UPS I wanted to get fancy and replace the battery with one that had more capacity. The original battery was a pair of 1270s - that's 12 Volts and 7 Amp-hours. Initially I was going to replace is with two 1290s - same physical size but larger 9 Amp-hours. This should work, just be longer to charge up and last longer than expected. Instead I tried using a pair of LiFePO4 batteries with built in battery management systems. Advantages would be 10 Amp-hour capacity and a 10 year battery life instead of 2-4 years like the OEM gel cels. First test worked great with the expected runtime. Second test after letting the UPS charge them for 2 days failed immediately. In spite of what the UPS said the batteries never charged up. Other people with the same batteries in their UPS have had better results.
