Hi all,

I had this laptop (Lenovo Carbon X1 Gen 6), and when it had Debian, it would just go flat on sleep, and even when powered off. So strange. I checked all BIOS settings etc, but could never figure it out.

I moved it to Fedora, and it was perfect. Battery life was boosted like crazy, acted as it was meant to.

However, I have tomove away from Fedora, due to them dropping X11 (it’s an accessibility issue I’m facing with my tools) and I forgot about said issue with Debian.

Back on Debian now, woke up, powered on laptop, which was fully charged last night, and it’s flat again.

What is it, that Debian is doing differently, that is making it go flat, when powered off?

Please note, I am doing a proper shutdown. Not just closing lid, sleep, hybernate, etc.

Any advice greatly appreciated. Thanks so much!

UPDATE: I booted into a fedora live disk, and shutdown. This time the battery did not go flat at all when shutdown, indicating that it is absolutely debian related, not BIOS or anything else.

    Just an update, for interests sake, for those that helped me. Get this, it’s if I have the laptop plugged into power as I turn it off. I then unplug it, and it drains like crazy when OFF. But, if I unplug power, then power down, it keeps its battery beautifully. How strange.

      so what you’re saying is that the firmware powers off when on battery and just suspends if on AC? I have to say I’ve never heard of such a thing. could be a setting in the DE; e.g. Plasma has a buncha stuff to set up separately for when on battery and when on AC, maybe your issue is there. does it behave the same when you power down from terminal (sudo shutdown -h now)?

      also, not to hamper your impressive research, but what’s with the powering down of things? all my hardware (desktops and laptops) get powered down or restarted like never or rarer. when it’s time for bed, they get suspended and then woken in the morning, ready to go as I’ve left em. the one laptop that spends days without power, ready to go when I have to leave, has the suspend-then-hibernate thing implemented so its power drain iz zero.
