And it’s crap across the OSes. On Linux laptops don’t wake up from sleep, on Windows they keep waking up when nobody asks for it.
In our home office room there’s three laptops. My private one running Fedora, my work PC that sadly runs Windows and my wife’s laptop also running Windows.
My work laptop and my wife’s laptop keep waking up wasting electricity, and my private laptop needs a hard reset to wake it up every second time.
That feature should be stupid simple, yet it doesn’t work across the board.
Rant over.

My laptop uses 0.07w sleeping, draining about 1.8% of the battery per hour. I would say that’s acceptable with 32GB RAM s2idle
Framework 16 on NixOS
Hell, why is sleep so hard for most humans?
Stop judging, at least I made it to bed. It’s not my fault sleep can’t find me.
Sleep is easy, you just prioritized that 30 minute YouTube video
And it’s crap across the OSes.
Never had these problems with MacBooks. It’s probably one advantage of the OS and hardware being made by the same company.
Agreed. For all the downsides people point out with Mac’s, they handle this and battery life quite well. My daily driver is a Mac, and everything I connect to runs some flavor of Linux. Then there’s the Windows 11 thing my work foists upon me.
That’s fair, never had one, so I can’t judge that.
I never had problems with sleep. Neither with fedora nor suse nor arch
I wonder if the hardware you use is better supported for/by Linux.
The problem is it’s not stupid simple, it’s actually fairly complicated. Each piece of hardware and its driver must be suspended. The GPU is a particularly tricky one. Its processor must be suspended, and the state saved. In the kernel, the driver must suspend its execution, and likewise save its state. Then on resume, each half has to reload and begin execution again. And if there’s any mismatch in the resumed states, the GPU and/or driver crash and probably take the kernel with it.
Now do that for the Wi-Fi, Bluetooth, sound card, USB, disk controller, and every other device.
This guy sleeps.
What are you talking about? This guy dies and comes back alive every time!
No, that would be hibernation
I researched this in (checking notes) 2009 or so… things may have slightly changed since (and my memory is fading away)
At the time there was a standard for sleeping. Microsoft was part of the standard… and then they decided to implement in a different way (classic Microsoft, of course).
Hardware producers then adjusted to windows because… well… we were dozens of us using Linux on laptops.
This created issues in Linux because there were some purist developers that wanted to follow the standards, others that were more pragmatic and wanted to implement the windows way. In the end nothing worked.
Fast forward to today, windows waking up constantly I guess it’s broken as expected because it wants to allow background processes to do stuff. Linux not waking up sounds still the issue from 2009: there are multiple levels of sleep and the deepest was the most problematic. If I have to guess your laptop wakes up just fine if the battery is full and you left closed for few minutes… while it doesn’t when the battery is low-ish and/or you left sleeping for a longer period
It’s waking up because another device on the network (probably router) is pinging it
Disable “Wake on Magic Packet” and the Windows sleep issue goes away
This kind of stuff must happen at hardware level… wake on lan is in hardware.
Ethernet cards keep in getting packets (arp at very least) even if they are not directed for them. If the OS needs to check all packages it would be always on
That said… wake on lan is also a waste of energy if you don’t need (why powering the Ethernet cards?)
The setting I am suggesting gets disabled keeps the card powered during sleep so Wake on LAN can work on a hardware level.
The OS isn’t checking the packets. The NIC gets a packet and wakes up the OS.
I am not defending it, just explaining how to stop it from happening. A lot of people who know what Wake On LAN is don’t know about Wake On Magic Packet
I have an old Dell XPS 13 sleep works great on for Linux probably can sleep a week or two and still have charge left when I open the lid. I have a newer framework and it’s dead in 2 days while “sleeping.”
Newer Dells have removed the s3 deep sleep. I believe the cutoff is between Intel 11th gen and 12th gen in (at least) Latitudes. I have a i7 12th gen that sucks at sleep, but an i5 8th gen that sleeps well.
First thing I do on any OS, but especially linux, is turn off every sleep-related option permanently. I don’t care anymore. I won’t fight with it.
In 35 years of experience I’ve never got it to work correctly on any OS except IOS. I’ve only met ONE tech who claimed it worked for them, and that was in the 2000’s. He couldn’t demonstrate how exactly.
I do the same thing, turn that shit off because it does not work.
Yeah I don’t bother with sleep either, I just turn all my stuff off when I’m done with it. With the advent of SSDs and M.2 drives, it takes about 10 seconds for my desktop to boot from fully powered off. I can wait that long lol
Trouble is you’ve then got to re-open all of your apps again. As a developer I have about 10 different things open (including zellij sessions and panes). I’ve started just leaving my computer on 24/7. How much does it cost me per month? Better not think about it!
wakes up when nobody asks for it.
Wrong. You might not have asked for it, but it is not your computer, it’s Windows’ computer. Microsoft decides when it wakes up.
Fair.
my guess is because the CPU power levels are fucking trashed because of all the patches they have to run at runtime. before Intel went all “wild west” with their security practices to improve performance, sleep worked just fine for me.
keep in mind, this was before uefi too, so it might also have a hand in the problems.
In my case its because Sony messed up the bios in more ways than one and refuses to correct the problems. They work around it with their own drivers witin Windows and leave it like that, but it also breaks Linux functionality as a result.
on Windows they keep waking up when nobody asks for it
Good to hear.
weirdly i have the windows problem on linux with my laptop: never have I had it not wake from sleep, but sometimes it starts overheating while on sleep and drains the battery super quick
many times ive put my laptop on sleep in my pouch, taken it out and hear the fans blasting, the laptop is burning hot and the battery lost 40% in 20 minutes
Never had I problems with sleep. Neither with arch, suse, fedora nor ubuntu. Neither with Gnome nor with kde.
Not even with windows.
Must be the hardware (brand).
The laptops are Lenovo LOQ, HP (work laptop) and Gigabyte.
My system76 wont even go to sleep anymore. It just pretends, then if i put it in a backpack for a bit it is burning hot.
System76? Shouldn’t they have support for such a case?
No idea how system76 configures their builds.
I’d check awiki if nothning else helps.

Possibly, tbh I spent a few hours on it and gave up, the laptop is due for a replacement anyways. It has other problems too, the touchpad connector is very flaky. Not sure I would go with them again…
Good to know, so far their on my buy list. Maybe not anymore :D My laptop is old but still works very good
ACPI is weird and sometimes hardware dependent, so it’s really hard to support it on every device. that’s my current understanding at least.
