Unfortunatley, the E series is way too heavy for my liking. At over 3.5 pounds, they are 50% more heavy than the X1.

No coil wine on my XPS 13 Ubuntu Edition. The only down side is that new Dell laptops don't support real sleep mode, so you'll open your laptop after a weekend with only 60% battery left.

  Which model of XPS 13? There have been so many different ones over the years. And what is real sleep mode? Suspend to disk?

    Sleep state S3, where the memory is still powered, but other chips including the CPU are not. This is the classic sleep state. These days we have "modern standby" instead, which keeps all things powered somewhat to allow for a quick wakeup by notifications for example. Just like your mobile phone. In theory, at least.

      What? This is disastrous! How do I check (from Linux) if the laptop can go into suspend to memory or not?

        Might mention ACPI state options in dmesg early on during boot, or you could probably poke at some ACPI diagnostics/options to see the capabilities. I think `cat /sys/power/mem_sleep` should tell you the desired modes; the active mode is selected and iirc changing one is done by writing the name of an option into the file. There are some related files next to `mem_sleep` in `/sys/power/`.

        If you are very lucky, you have an option in the BIOS to enable S3 sleep state. If you are moderately lucky, you may not have this _yet_, but you get it with a BIOS update. But even if you have it, Linux might be hit and miss - sometimes it works, sometimes not, usually crippling some device like the touchpad after a wake-up. You can try `cat /sys/power/mem_sleep` to see what states you have available. "deep" is what you want. "s2idle" and "shallow" are the ones that are just "low-power". EDIT: actually, after a bit of web browsing it turns out that Intel 11th gen and above do not have S3 support anymore. So don't wait for BIOS support, it won't happen...

        Yeah, only s2 here. Would switching to an AMD laptop fix it? Strange, that KDE still writes "Suspend to RAM" under the "Sleept" button when it cannot do that.

    The 2022 model. By real sleep mode, I mean suspend-to-RAM, or S3. A few years ago, Microsoft declared that they will no longer support sleep mode, and will just call S0 mode "Modern standby" so they can keep doing telemetry nonsense 24/7 when people think their laptop is asleep. Dell saw this and decided that they don't need to support S3 mode in the BIOS any more because they don't want to put in the effort just for Linux users. https://martinpoehlmann.com/posts/tech/2021-07-30-dell-s3-modern-sleep/ https://martinpoehlmann.com/posts/tech/2021-07-30-dell-s3-mo... https://libreddit.privacydev.net/r/Dell/comments/h0r56s/getting_back_s3_sleep_and_disabling_modern/ https://libreddit.privacydev.net/r/Dell/comments/h0r56s/gett...

      Crazy. I have my laptop in "Suspend to Ram" all the time when I don't use it. And I don't want it to be able to wake up from this or do anything unless I press a button.

    >Suspend to disk? Not even that. Suspend to RAM is gone. It was perfectly fine, until someone had this great idea that PCs should behave like cellphones: just turn the screen off, meanwhile stay awake and connected. Hopefully it means doing the minimum necessary to receive and notify emails, but in practice this means the laptop will decide it's time to run the antivirus scan, do your scheduled backup and perform all kinds of maintenance right when your laptop is in your backpack and you're on your way to work. Microsoft calls it Modern Standby. I think there's also a degree of pushing on the manufacturers' side, as it's not purely an OS thing: sleep states must be enabled at the BIOS level for the OS to use them. Lenovo allows enabling the "legacy" sleep state, Dell does not. See the previous shitstorm here: https://news.ycombinator.com/item?id=28646776 https://news.ycombinator.com/item?id=28646776 As far as I know, it's still no less of an issue to this day.

  I believe with dell, coil whine is somewhat of a lottery. I have it bad on the XPS15. Some people don't have it and they are lucky.
