> With regards to transporting your laptop, you must first turn the laptop OFF

This has been a problem for already quite long. 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. I go and disable the "fast start up" (Control Panel - Power Options - Choose what the power buttons do) to make sure the computer gets turnt of for real rather than using yet another flavour of hibernation. And it still starts very fast (a couple of seconds longer perhaps) so I see no reason for these "fast start up" and "modern stand-by" modes to even exist now as we have fast SSDs and everything.

Besides starting up fast, another important value standby modes add is freeing you from having to open, position and initialize (open the documents/locations in them) all your apps manually every time. But this seems trivial to be reached by adding functions to just save the list of opened apps, their windows positions and the actual documents which were opened in them. This will require some coordinated effort from both the OS and the apps developers though.

I've had hibernated laptops wake up for whatever reasons in bags before. They get super-hot and shut down. Come to think of it, they were Dells. Perhaps some switch is not properly debounced or something.

The Surface Pro 4 had that problem for months after its release. https://www.reddit.com/r/Surface/comments/4hnhuz/just_took_m...

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.…

Oh wow. i did NOT know that. Even worse...

>Switching between S3 and Modern Standby cannot be done by changing a setting in the BIOS. Switching the power model is not supported in Windows without a complete OS re-install.

and on Reddit

>Warning: if your laptop is newer than 2019, there is a high chance, your OEM removed any S3 code from the bios, and your laptop will crash entering S3 and you have to force hold power key to restart and then delete the registry entry again to revert back to modern standby.

so not only is microsoft screwing around.. its getting all the manufacturers to screw around as well?

Clickbait. What they actually say: " Under no circumstances should you leave a laptop powered on and in any sleep/hibernate/standby mode when placed in a bag, backpack, or in an overhead bin. The PC will overheat as a result of that action. Any resulting damage will not be covered by the Dell warranty. " Fair enough. A laptop that overheats because it's been left in an enclosed space whilst not off is not damage caus…

I don't think this is clickbait; I think any normal user would think that closing the lid puts the laptop into a state where putting it in a bag is entirely safe to do.

Microsoft seems to have decided to entirely break this expectation such that closing the lid of a laptop puts it into this weird not-really-suspended state, such that putting it in a confined space could cause it to overheat. It's... pretty user-unfriendly and IMO stupid.

I once investigated why a PC occasionally turned on all by itself and at first suspected that something on the network might be sending wake on LAN packets. It turned out that the PC was only in sleep mode and not hibernating and that Windows can wake it up from there, e.g. because of scheduled maintenance. What was even more surprising, it will go back to sleep once it is done.

You might want to check the event viewer in cases like that.

Funny enough, I actually had a plenty of issues with XPS and Linux. The machine would not go to sleep when I closed the lid and put it in the bag. The result - an extremely hot and loud laptop. I think that may have been a BIOS issue, as it stopped happening after a year or so.

The thing is, XPS laptop have issues going to S3 Sleep/Modern Standby. There are many threads about battery draining due to this.

The question is, why isn't the laptop shutting down properly when it begins to overheat inside a bag? In any case, this will probably not void the warranty in most countries.

In case anyone is curious I wrote up how I use suspend (amongst other things) with my XPS 13 running Debian: http://h2.jaguarpaw.co.uk/posts/how-i-use-debian-dell-xps-13...
