I've recently got a MacBook at work (after years of Windows/Linux usage) and was amazed by one feature. When I close the lid of the laptop and leave it for 2 days, its battery is not drained to 0, yet all the apps are still open when I open it again. Magic.

I wonder if non-Apple manufacturers will some day in the future add this killer feature to their offering.

My Lenovo ThinkBook 14 G2 ARE (Ryzen 7 4700U) does exactly the same. Close the lid, wait two days, open the lid - the battery is drained about 10% and... Magic.

This is on Linux, and the only reason for reboot is if there is an updated kernel. I once postponed the reboot for more than 3 months.

Same here. Different hardware (much older) and Windows 11.

Haven't rebooted that machine in weeks either.

Does it support S3 sleep state? Most of recent laptops have removed it

> leave it for 2 days, its battery is not drained to 0, yet all the apps are still open

Isn’t that normal behaviour? Mine thinkpad T14 still has battery after a couple days sleeping.

Unfortunately, it's not normal these days. How old is your T14? It seems like it's becoming increasingly a problem for Thinkpads as well (e.g. https://forum.thinkpads.com/viewtopic.php?t=134241 )

It's a windows bug with S3 sleep. Microsoft is supposedly currently trying to fix it since LTT made a video about it

I doubt MS is honestly trying to fix it, since it was MS who introduced Connected Standby as a replacement for S3

And I don't think it's just a software bug - many laptops now don't offer S3 at all, some only after toggling a BIOS option. Even then, it's often buggy on Linux as well.

> Microsoft is supposedly currently trying to fix it since LTT made a video about it

Certainly not because, if that's the implication. Maybe since then in time.

Well, they said that a VP called LTT in response to their video, which is why I said supposedly.

Mine is T14 Gen1 AMD with Alpine on it so I'm off the hook as it seems.

My P14s Gen1 AMD (very similar to T14) with Debian still has this problem. 2 days unplugged will drain the whole battery and turn off. Maybe it's because I kept a Windows partition around?

Updating the BIOS via fwupd fixed it in my case, running Debian testing on a P14s Gen1 AMD.

Protip for Linux users:

1. Configure your system so that hibernate works. 2. Set `HandleLidSwitch=suspend-then-hibernate` in `/etc/systemd/logind.conf` 3. Optionally change `HibernateDelaySec=120min` in `/etc/systemd/sleep.conf` to something that suits you better.

You can now close the lid of your laptop and leave it for _months_ without the battery draining to 0, and still resume your work from where you left it.

I wonder, will "protip" can be used by "pro" users who for sure don't have `systemd` on their uniq and so special needs setup? ;)

My work provided Lenovo Thinkpad T490s (2019) running Windows 10 does this. It is called "sleep mode"

My desktop from 2014 does the same.

Yes, I have heard problems with "modern standby" but have not experienced any issues.

Meanwhile, when I let my iPad lying around unattended for 20 seconds, the thing immediately feels lonely and drains its battery to zero...
