"Just this week I have a friend who bought a brand new Alder Lake laptop who is desperately trying to install the latest available kernel and firmware seeing the HDMI port does not work, nor does the laptop go to sleep properly." Good to see that the good old "laptop doesn't go to sleep on linux" problem has never truly gone away.

To be fair to Linux, sleep doesn't work reliably on Windows either. The new Intel sleep states just don't seem to be reliable enough with modern software, to the point of at least one laptop manufacturer recommending customers to not carry a laptop in sleep mode in a backpack. The HDMI issue is ever present. Intel has lately been dropping the ball significantly with their drivers, but at least it's not Nvidia this time, so that's a change!

  I mean, yes, of course - I'm just making (a little bit of) fun out of the fact that "laptop sleeping reliably" has traditionally been a benchmark for how complete Linux support is for that specific laptop. But yes, I've had 4 Dell XPSes, all running windows, and all of them have had at least one episode of the laptop cooking itself inside a bag - I pull it out and it's literally burning to the touch, because some stupid event decided to wake it up, despite the lid being shut.

    I've had to switch to linux full-time on my latitude for precisely this reason. It sleeps perfectly and the battery life is a lot better on linux than on windows. The good thing about Dell is that they ship with linux on certain configurations, so linux installs are very robust with the caveat that you will not see the agressive fan curves or higher tdp limits that you can get on windows.

  Yeah my 6 year old i7 laptop just shuts down completely when told to sleep, both in Windows and Ubuntu (always has since I bought it). It's definitely some kind of firmware thing that Intel is royally messing up on a grand scale.

  Even on freshly imaged Microsoft Surface hardware, I have problems with Windows going to "sleep" (since it's connected standby, not sleep). About 25% of the time the IR webcam will get stuck always on, preventing the Windows Hello face-based unlocking to work and resulting in the IR blaster heating significantly. Reproducible even on an image with all the latest MS updates.

> Good to see that the good old "laptop doesn't go to sleep on linux" problem has never truly gone away. FWIW, I have a spare Windows laptop, just over a year old, whose WiFi does not recover upon waking from sleep about eleven times out of a dozen. OTOH, I have had both Windows and Linux laptops which have gotten uncomfortably warm when ‘asleep.’ And right now I have a Linux laptop which very rarely hangs on sleep and turns into space heater, not even turning off the monitor but becoming completely unresponsive. Sleep is apparently a lot trickier a feature than it looks.

  So it only works reliably on Macs?

    There are problems with Macs too as recently as the last release where the laptop would have a bit set preventing it from sleeping that you could only see from the terminal.

    No, it works reliably on many individual PCs as well. Comparing the entire PC ecosystem to a couple models made by a single company is a category error.

  Blame Intel, their power management code's an ever changing mess.

    I have 2 computers with AMD, sleep glitches on both. On desktop, sometimes there's no video signal after wake up. The laptop doesn't support sleep at all, it's either connected standby = not sleeping, or hybernate. Windows says none of the proper S1-S3 states are supported by the computer.

My desktop computer doesn't sleep properly thanks to the Nvidia driver. All my computers worked fine for years and I definitely should have done more research before "upgrading".
