From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I just installed EndeavorOS on an HP Spectre360 that’s roughly 2 years old. I am honestly surprised at how easy it went. If you google it, you’ll get a lot of “lol good luck installing linux on that” type posts - so I was ready for a battle.

Turned off secure boot and tpm. Booted off a usb stick. Live environment, check. Start installer and wipe drive. Few minutes later I’m in. Ok let’s find out what’s not working…

WiFi check. Bluetooth check. Sound check (although a little quiet). Keyboard check. Screen resolution check. Hibernates correctly? Check. WTF I can’t believe this all works out the box. The touchscreen? Check. The stylus pen check. Flipping the screen over to a tablet check. Jesus H.

Ok, everything just works. Huh. Who’d have thunk?

Install programs, log into accounts, jeez this laptop is snappier than on windows. Make things pretty for my wife and install some fun games and stuff.

Finished. Ez. Why did I wait so long? Google was wrong - it was cake.

See what happens after actually running:

systemctl hibernate

Systems don't normally enter hibernate automatically unless they are at low battery. There is something called modern standby or s0 sleep, versus traditional s3 sleep. The "third state" you describe sounds very much like s3 sleep. I doubt it would switch between s0 and s3 sleep though, normally one or the other is enabled. Maybe it's going to hybrid suspend? In fact that would probably explain it. I believe hybrid suspend involves using s3 sleep state.

Also there are no power relays in modern ATX PSUs to my knowledge, you are describing something else. They use transistors to do all of the switching I believe, aside from the physical switch on the back which also isn't a power relay.

Excellent, that makes sense. I’ll try that command tonight at home, see what it does, and report back. I kind of want to know what it’s doing just because I’m curious.

I say a relay, but I agree with you - I couldn’t imagine a relay being used. But whatever it is on my desktop, it sounds just like a traditional ice cube relay clicking - and it’s quite loud. But I have no idea what it is. I’m not sure I’ve ever had a computer that made that noise before. My laptop makes no such noise obviously.

Could be the transformer, or the inductors. Those can move when in use and they can also make sounds like coil wine.
