BX1500M restore after power outage

[rgagarskiy]

I ran into very specific usecase with my recently purchased BX1500M UPS, curious if people here experienced anything similar and there are workarounds.

I have a windows PC powered through the mentioned UPS and connected with a usb cable to the data port of the UPS. When the external power goes down (tested with unplugging the UPS from the wall socket), the PC gracefully shuts down - no problem with that. if the power goes back again after some minutes - the PC starts normally.

However if the power goes back when UPS is in a cycle of shutting down the PC (it is about 1 minute), the UPS just keeps its sockets powered and the PC never gets a signal to start again because it never loses the power (the setting in BIOS only works for the cases when the power was lost).

Any ideas for a workaround?

The auto start function of the UPS relies when the computer is totally powered of and the bios of the Computer detects that the power is restored that means that you need to have a period where in the computer is totally turned off and the UPS will cut power and will restore power signalling your computer to start up.

So you need a power on delay which is not available on the Back- UPS line of APC and is only available on certain Smart-ups UPS such as the SMT SMX and SRT line of UPS

Another work around is setting up a watch dog device that will send signal to the  and when the computer is  not responding it will send a signal to the computer to wake up  and the computer must be setup to wake up on LAN

Thank you so much for the answer, very much appreciate the mentioning of particular models that do support the needed feature. However I would agree that for a home solution I would probably use a watchdog.
