Hi,
I've installed Archlinux on my laptop a few days ago. I've noticed a problem when my laptop is shutdown : I loose battery (between 2% - 5% during a full night).
When my computer is shutdown, I can hear a little noise coming from my computer, so I think that a component is not fully shutdown.
I've got an Acer Swift 1 (SF114-31-P9N8), with the latest kernel (4.17.4-1-ARCH), and I've also installed manjaro, but I've got the same issue.
I've read that it could be because of WoL, but the option doesn't appear in my BIOS, so I think it's not linked.
However, I've found a workaround : when I hit "shutdown' in KDE, the system launch a script that runs the command "halt". Then I just have to press the power button until the computer turns off. I know it's not a good solution, so I'd like to fix this problem using the right way.
I hope someone will be able to help me,
Thanks!

Two things I would check that might be drawing power
- WoL. Even if there is no bios option, check whether it is enabled for your adaptor https://wiki.archlinux.org/index.php/Wa … figuration
- wake on usb. Look for EHC or XHC in /proc/acpi/wakeup

Thanks for the anwser.
I've ran the command cat /proc/acpi/wakeup*, and it gave me :
XHC1 S3 *enabled pci:0000:00:14.0
BRCM S0 *disabled
BRC1 S0 *disabled
HDEF S4 *disabled pci:0000:00:1b.0
RP01 S4 *disabled pci:0000:00:1c.0
PXSX S4 *disabled
RP02 S4 *disabled
PXSX S4 *disabled
RP03 S0 *disabled pci:0000:00:1c.2
PXSX S4 *disabled pci:0000:02:00.0
RP04 S4 *disabled
PXSX S4 *disabled
LID0 S4 *enabled platform:PNP0C0D:00
So I've seen that "XHC1" is enabled, so this might be at the origin of the issue.
But I don't know how to disable, anyone have an idea?
Thanks

echo "XHC1" > /proc/acpi/wakeupwill toggle it.
Might also be worth checking whether there is a BIOS option for this. There is on my dell laptop.

Sorry for the late reply, but I was on holidays in another country far from my computer.
I've run the command, but it didn't change anything.
But I'm not sure that it's the origin of the issue, as it says that it is active in S3 state, so when the laptop is on standby.
Anyway, I didn't find any option linked to Wake Up on USB in my BIOS.
Thanks !
