That's because they know how shitty is sleep function really. Ok, laptop is in a sleep mode successfully. But doing anything to it or even looking at it funny will immediately wake it. Moving mouse, switching off mouse, inserting or removing mouse dongle, inserting or removing headphones and so on. I simply stopped using sleep mode altogether.

Spoiler: I have an XPS 9500 under Linux, which sleeps fine under S3 but then it never wakes up. So the problem isn't with Windows.

So you’re actually "putting it to sleep", when you put it to sleep.

The issue is that Windows doesn't go into S3 sleep when you close the lid; it goes into a weird not-really-asleep state for... some reason that I don't agree with[0]. I guess that state is "hot" enough that you could damage the laptop by putting it in a bag while in that state. Fortunately I've been running Linux on my XPS 13, which I have put into a bag hundreds of times (maybe even over a thousand) while suspended.…

I have dell XPS, it had perfectly functional sleep and could be put in a bag. Then 'modern standby' was added in an update and it ruine the laptop - if I place it in the bag in the morning, by linchtime it will be crazy hot and the battery will be gone. And you cannot diaable this feature. I don't get wtf these people are smoking.

On my Dell, this problem happens when you suspend the laptop from software (either with pm-suspend or systemctl suspend). If you simply close the lid, it seems to enter in a different "mode" of suspend, the real one, where you can carry it without overheating and the battery lasts for weeks.

It's terrible. I remember being woken up one night because my laptop decided to wake up and resume the Netflix video I'd be watching earlier. No input devices connected, lid closed. Another time it cooked in my bag because windows wanted to do an update on shut down so I slept it instead.

I have a 2017 XPS model so I the firmware supports S3 sleep. There is no modal in the BIOS though. I had to trick windows into thinking it didn't support modern sleep.

Based on posts from others trying to do the same thing, it used to be a single registery key edit. Now it's convoluted and required fiddling with WiFi power controls. The end result it sleeps properly but takes anywhere from 10 seconds (good) to more than a minute (bad) to connect to WiFi when woken up.

Of course on Linux it just works.

Back when I was looking into this I found someone who'd found a way to patch the acpi table to enable it for the newer models (at risk of bricking the device entirely). Alas I can't find the link any more.

I won't buy another Dell until this is fixed.

My work laptop is an X1 carbon and it supports only S3 sleep so it just works.

I remember my very old laptop overheating if being put in the backpack in Standby mode. Nowadays I in fact don't just turn laptops Off the default way.

Wow, it's quite fascinating what you non-Mac people are willing to put up with. Or maybe it's fascinating how Mac JustWorks(TM).

So if I understand it correctly, you have to manually shut down these laptops if you want to travel/commute with them and reboot them again when you want to use them, and they call that "MODERN" standby? And not even an option to change it?

Are they planning to keep that obviously broken behavior as the forum post seems to imply, or they will fix it?

I have an XPS 9500 and have found this infuriating. I think there's two separate things going on: As others have noted, S3 sleep isn't supported, only S1 "sleep to idle" sleep. But I don't think this is the direct cause of the overheating. In S1 sleep, the laptop can average something like 900mW of power usage, which is enough to annoyingly knock a few percent off your battery overnight, but not enough to make the la…

I also have a 9500. I'm considering selling it, the hardware is just so buggy.

If I do I'll probably buy a framework laptop.

This is so infuriating, because this problem has already been solved once. It's called "Hibernation", and was added in Windows 95. This should write your MEM image to disk, power the laptop completely off and allow later restoring where you left when powering your laptop back on. But laptop manufacturers (including Apple) thought it somehow smart to remove true hibernation, and replace it with some botched "deep slee…

There’s some really interesting security challenges that pop-up with Hibernation. Not sure if they blocked Apple though.
