I'm having issues with my PC where it refuses to boot up again after I shut it down or put it into hibernation/energy saving mode. Once the PC is powered down, it doesn't respond to the power button at all. The only way to get it to start again is to completely disconnect the power for about an hour. If I try to power it on too soon, I find I have to wait for another hour. Interestingly, if I jumpstart the PC via the pins, it starts right up, but that's not a practical solution for me.
Here are my specs: TUF Gaming Z690-Plus D4 and Intel Arc. I've already tried several troubleshooting steps including disconnecting my audio card, testing with both Windows and Linux (no OS error found), adding an external power button, updating the BIOS, and even taking it to a computer repair shop where they couldn't find any issues. It worked fine at the shop, but the problem persisted when I got it back home. I've also tried different power sources and disconnecting my graphics card.
I've noticed that when the PC shuts down, there's a brief moment where it seems like I could turn it back on, but afterward, it doesn't respond at all. This issue has been ongoing for about six months, and I'd appreciate any guidance or insights since the advice I've received so far has been inconsistent.

I've always turned off sleep and hibernate modes. They can lead to quirky issues that are tough to track down. I prefer waiting the extra time it takes to boot my PC without those features. Honestly, I think it's one of the worst things Microsoft ever introduced.
Does the PC completely shut down each time you try to wake it up? Just making sure I understand your situation. You mentioned it only boots back up after leaving it off for a full hour, right? Do you have any overheating issues? Let me know if it’s working fine otherwise.
Exactly! When I hibernate or shut it down, it doesn’t respond at all until I've cut off the power for about an hour. I even tested the power button with an external one, but no luck. There’s no overheating—everything runs smoothly otherwise, including when I took it to the shop.

I understand your approach. I’ve already tried disabling those features, but the issue persists, even with a complete shutdown. It’s baffling, especially when the system crashes.
