No S3 for LID in /proc/acpi/wakeup?

Since the last update my laptop (MacBook Air) does not wake up when I open the lid; I need to use the power button. It used to work fine before. Investigating the issue, I noticed that in /proc/acpi/wakeup the LID is in state S4 instead of S3. More precisely, here is my /proc/acpi/wakeup:

Device  S-state   Status   Sysfs node
PEG0      S3    *disabled
EC        S4    *disabled  platform:PNP0C09:00
HDEF      S3    *disabled  pci:0000:00:1b.0
RP01      S3    *disabled  pci:0000:00:1c.0
RP02      S3    *disabled  pci:0000:00:1c.1
RP03      S3    *disabled  pci:0000:00:1c.2
ARPT      S4    *disabled  pci:0000:03:00.0
RP05      S3    *disabled  pci:0000:00:1c.4
RP06      S3    *disabled  pci:0000:00:1c.5
SPIT      S3    *disabled  spi:spi-APP000D:00
XHC1      S3    *disabled  pci:0000:00:14.0
ADP1      S4    *disabled  platform:ACPI0003:00
LID0      S4    *enabled   platform:PNP0C0D:00

If I understand correctly, I need to have S3 instead of S4 on the last line. How can I do that?

Hi,
I do have the exact same problem. My proc/acpi/wakeup looks identical.

Did you find a solution by now?

Kind Regards
Michael

No, I was not able to find a fix. However, I downgraded a few packages that could have been the cause and now it works fine. More precisely, I ran the following command:

 sudo pacman -U /var/cache/pacman/pkg/linux-4.16.10-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/linux-firmware-20180518.2a9b2cf-1-any.pkg.tar.xz /var/cache/pacman/pkg/systemd-238.76-1-x86_64.pkg.tar.xz /var/cache/pacman/pkg/libsystemd-238.76-1-x86_64.pkg.tar.xz  /var/cache/pacman/pkg/linux-headers-4.16.10-1-x86_64.pkg.tar.xz 

Now it works but /proc/acpi/wakeup is still the same (still have S4 on the LID line). I will try to update again later.

S4 in the wakeup table means that the device can send wakeup signals in all sleep states up to S4, so it should also work with S1, S2 and S3.
