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.
It was a couple hours. Just like on my desktop, wiggling the mouse wakes it from sleep, but not so in whatever that second state is when it’s left for longer. It definitely was something other than sleep. What it was - I’ll let you guys decide. Whether it behaves long term with fans in a laptop bag, that I don’t know - I haven’t had enough run time with it.
I’m just sharing a positive experience. If I see it misbehave I’ll be sure to update the thread with reality. But so far, it really is behaving much better than I expected.
Wake from hibernation usually requires to press the power button, because the computer is off.
Sleep is not disturbed by wiggling the mouse because this trigger is usually disabled on laptops, as it would happen involuntarily.
I did some more digging on this last night. I’m more confused now than I was before, and I don’t know what it’s doing.
The arch wiki defines three states, suspend to ram (sleep), suspend to disk(hibernate), and a hybrid suspend(presumably what my steam deck does).
First there is the “turn off the display” behavior. Doing anything brings the monitor back alive and I’m presented with the Lock Screen.
Second is what I believe to be sleep. This happens when I select “suspend” from the menu or leave it alone for a very long time. This mode doesn’t happen soon (maybe at all) if the computer is doing stuff. It appears to be in a lower power state-but I can’t say why I think that (maybe it’s just because the fans aren’t running? I dunno). Wiggling the mouse or doing anything wakes it back up.
Third is another state. It’s just like the above state, except it will not wake up with mouse movement, or clicking keys on a Bluetooth keyboard. I must push a key on the keyboard, the power button, or open the lid. It’s weird because it responds to things other than the power button.
Interestingly, my desktop behaves exactly the same way. But what’s interesting on the desktop is that I can hear a power relay clicking on from this third state. It’s distinctly different than the 2nd state - exhibiting power cutoff, but still responding to the keyboard.
Neither computer enters any other state even after days of being left alone.
So I dunno. Are modes 2 and 3 like two versions of sleep, and hibernate never activates? Or is state three hibernation but it responds to things it shouldn’t?
I have no idea. But now that I’ve played with it some more - I don’t want to say hibernate is working because I don’t know what it’s doing. All I know is that it has the above three behaviors which are consistent with my desktop machine.
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.
