Why is sleep so hard for laptops? (lemmy.world)

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.

@squaresinger@lemmy.world It's probably because my kernel version is very old (5.14.11-arch1-1, haven't updated since 2019, even though it's Arch, a rolling-release distro) and my Acer laptop is old as well (Intel Core 7th gen), but I rarely have problems regarding laptop sleep. After I wake the laptop up, the video (including every VT#) may get frozen and I have to remotely SSH and request a reboot (and when this happens, sometimes the reboot gets stuck as well, so I have to do a hard power-off). But it's very rare, as stated, and I daily put my laptop to sleep without issues, sometimes the system uptime stretches to weeks (currently, my system was booted almost four days ago).

It does work fine too on my 2010 EEE PC running Antix running on a 5.10.x kernel. Seems to be more an issue with newer devices, since every single laptop I own that's newer than maybe 2013 has these issues.
