This sort of trick will fix a lot of annoying little issues on most PCs, like if you have a USB device that you know works but your PC won't recognize it. Shutdown, unplug the power, then hit the power button on your PC a few times. Everything should be good. Works every single time I need it.
Once in a while after a resolution switch (e.g. exiting a game), one of my displays will go into its sleep mode and won't come back. Unplugging it and hitting the power button a few times fixes this, no PC restart needed. My friend had a TV that'd do something similar once in a while and this fix worked for him as well.
I'd be willing to bet the specific sequence in this article isn't really important, but rather that you're draining every capacitor in the PC by hitting the power button without a power source available (my understanding of what's happening with my fix).
- joezydeco 5y agoModern equipment usually has a power controller chip that sits between the power button and the actual "power on" signal that's sent to the power supply. There's no direct physical connection between the button and the PSU anymore. The one I usually work with (LTC2954) does have an RC circuit attached to it to determine how long to hold the button to force a shutdown. And I'd wager a guess that this is the capacitor you're discharging by kicking the controller a few dozen times. But there's no possible way I can see that you're discharging every cap in the system.
