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.

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-unfri…

Exactly. I would personally consider damage caused by an unreliable suspend mode (whether an issue of software or hardware) to be an example of manufacturer defect.

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.

Often it's a problem with the Linux ACPI settings. I had to write a script that checks entries in /proc/acpi/wakeup and disables them as the laptop will otherwise often immediately come back from sleep due to being woken by the ethernet card or another device. That's not specific to Dell devices. Otherwise checking syslog often reveals why going to sleep failed, sometimes it's a particular program that refuses to freeze.

Here's the script btw for those that have the same problem, you'll need to modify the identifiers based on your hardware after identifying which devices cause the problem

    #!/bin/bash
    (cat /proc/acpi/wakeup | grep "GLAN" | grep "enabled") && echo "GLAN" > /proc/acpi/wakeup 
    (cat /proc/acpi/wakeup | grep "XHC" | grep "enabled") && echo "XHC" > /proc/acpi/wakeup

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…

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 sleep" that is not actually working, as it does not actually turn the computer OFF. This is SO infuriating - who thought it smart to REGRESS on a solution that has worked so well for DECADES?

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.…

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.

The problem is that Windows defect breaks laptops not under warranty by Microsoft. Getting refund would be tricky, and voiding Dell warranty in such case seems justified.

What does "never wakes up" mean? I thought I had the same problem but then I discovered that closing and opening the lid is the only way to get it to wake. Neither the power button (it turns it off) nor keypresses (they do nothing) work.

Closing the lid does not necessarily turn the laptop off at all (by design). I think most people have had that experience. In fact the lid may be closed with the laptop fully on.

In any case, they make is explicit and clear exactly to avoid any such assumption.

The title is obviously clickbait because of course you can put your Dell laptop in a bag and of course that does not void the warranty.

Hardly relevant to the topic at hand, but I'd simplify this to

  grep 'GLAN.*enabled' /proc/acpi/wakeup && echo GLAN >/proc/acpi/wakeup
  grep 'XHC.*enabled' /proc/acpi/wakeup && echo XHC >/proc/acpi/wakeup

XPS15 owner here. Had this exact problem during the first year of ownership. Somehow Windows updates changed this behavior and I haven't had any more battery draining / overheating in bag since. But I will not buy Dell again. Too many little problems. I haven't had ONE problem of this kind with ThinkPad's, in maybe 25 years of use.
