The junction of the two resistors will be at 2.5V which will be read as a ON or high by a gpio port set as an input. On Windows 11, hibernation is a feature that can help preserve battery life when you are not using the device. The feature works by saving the data in memory onto the hard drive, allowing you completely shut down and resume where you left off without wasting power. I tested this using two RPi's on my home network and it seemed to work OK in terms of recognizing if the second RPi was live or not and showing the appropriate 'All is well' or 'Time for a restart message'. I wasn't able to test for a single missed ping response followed by a successful ping - but I'm sure you get the idea behind it. There you go, two simple methods to turning on your ATX power supply without having it connected to a motherboard. Being able to do this has been extremely helpful to me as a reviewer, however it also comes in handy if you run a high power Thermoelectric Cooler (aka TEC or pelt) that requires the use of a 2nd PSU.

I never thought of the pinging solution. Il have to work through that in my head and figure out the necessary commands to create a script (I can write that in batch in 30 seconds, but RPI doesn't run windows ) but it may be useful Note the stuff about 'today' is because I based this on a similar script I use for hardware monitoring and the script stops at midnight and a new copy is started just after midnight. Also if the RPi has to be rebooted, the script starts after bootup using @boot in the crontab, and I don't want two copies running when the new copy starts just after midnight. Standard" Toggle Switch used for turning On/Off Cooling fans or PC Lights. Type: On/Off 2 Pin Wire Connection. Power: 15A 250VAC / 20A 125VAC.I really want to do this without any extra hardware at all, just a Pi and the necessary connecting wires. Really hope some of the forum experts can lend a hand My PC won’t turn on” can mean quite a few different things. For the sake of clarity, we’re assuming that either your system isn't reacting at all when the power button on your case is pressed, or that it’s turning on for a second or so then shutting down again.

The first thing we want to do is to take a piece of wire, and strip off the coating on each end. Half an inch should be more than ample. The power switch you're referring to is for the power supply itself. This does not by itself turn on the computer; it merely allows the system to be powered on. JPWR1 (24 pins) is the main ATX power connector, while JPWR2 (8 pins) is the CPU power connector. These pins supply power to system components, and themselves do not turn the computer on.Momentary SPST (Single Pole, Single Throw) Switch - Your most basic momentary switch, press/flip/turn it to close the circuit, release and it opens.
