Laptop battery goes flat, when powered off, only on Debian (lemmy.ml)

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.

Jesus Christ, there is something very wrong going on in there lmao. So, if you just turn it off (no unplugging) I'm guessing it's chugging your electricity for no reason? Does it have any logs of something it could be doing while it's "off"?

Nope, nothing. And only on Debian. It never did this on Fedora. Madness, but, I have no time to further spend on it. So, unplug, send shutdown signal, and happy life. haha, weird!
