HATs and other add-ons • Re: Rpi 5 built-in power switch ("PSW"), and the ATX Watchdog hat

Is that an advertising post or a request for support?

Think it's advertisement as the power button on Pi5 is well sescribed in the documentation https://www.raspberrypi.com/documentati ... wer-button

The J2 jumper is located between the RTC battery connector and the board edge. This breakout allows you to add your own power button to Raspberry Pi 5 by adding a Normally Open (NO) momentary switch bridging the two pads. Briefly closing this switch will perform the same actions as the onboard power button.

So what additional info would you get from a schematic? Measure them and see if pushing the actual button impacts on their levels (any logic analyzer/scope/multimeter should do).

..
It controls an ATX supply, and needs a switch connected to two of its pins for powering everything on. With a jumper (that isn't part of the kit, but has a mounting location present on the PCB), it will provide regulated 5V power to the pi via the GPIO header. (It will provide whatever max current the connected ATX power supply can do.)
..

Think about that after you've read https://www.raspberrypi.com/documentati ... wer-supply; seems like you've misse something.
