Hi,
My laptop wakes from suspend on lid open - even if I disable suspend on lid close in KDE. Some research revealed that waking cues are controlled by /proc/acpi/wakeup. I disabled the lid event by doing “echo LID0 > /proc/acpi/wakeup”, after which cat /proc/acpi/wakeup gives:
Device S-state Status Sysfs node
P0P1 S4 *disabled
GLAN S4 *disabled
EHC1 S4 *enabled pci:0000:00:1d.0
XHC S4 *enabled pci:0000:00:14.0
HDEF S4 *disabled pci:0000:00:1b.0
PEG0 S4 *disabled
PEGP S4 *disabled
PEG1 S4 *disabled
PEG2 S4 *disabled
LID0 S3 *disabled
PWRB S4 *enabled
Which looks successful, but it didn’t work: opening the lid still wakes the device. Disabling PWRB and the others doesn’t change this either. Feels like /proc/acpi/wakeup is being ignored somehow.
Help? 
Systemd is taking care of this. Check /etc/systemd/logind.conf file. The settings in logind.conf look like this:

I would try changing LidSwitchIgnoreInhibited=yes to no.
**
LidSwitchIgnoreInhibited**
This means that the lid switch does not respect suspend blockers by default, but the power and sleep keys do.
Check man logind.conf 5 for more information.
Hi, thanks for the suggestion, but I’ve also tried that before already. My logind.conf:
~> cat /etc/systemd/logind.conf

So far no dice 
You really need to submit more info about your hardware. What brand and model of laptop are you using?
Check your BIOS or UEFI. Perhaps there is a setting that can be toggled.
Sorry bout that. I’m on a Lenovo Yoga 11s, haswell version. I did check my bios settings and didn’t find anything useful yet
I found this small Bash script on linlap.com/lenovo_ideapad_yoga_2_proThe original blog report is provided by an Ubuntu user here https://www.csslayer.info/wordpress/linux/yoga-2-pro-on-linux/**
Resume immediately after Suspend**
If there is a problem with the laptop waking up after you close the lid -- This script might be helpful. Add it to an Autostart folder. You must chmod +x script
#!/bin/bash
echo XHC > /proc/acpi/wakeup
echo EHC1 > /proc/acpi/wakeup
Closing the lid doesn’t always send the laptop to suspend, this is how to fix
This is a different script by an Ubuntu user. The blog recommends adding the lines below (NB - The numbered lines are just for your reference) to /etc/rc.local:
1 # Disable wake up on anything for Yoga Pro 2, otherwise it sometimes wakes from suspend
2 cat /proc/acpi/wakeup |
3 grep '*enabled' |
4 cut -f 1 -d ' ' |
5 xargs -n 1 -I {} sh -c 'echo Disabling wake up on {}... && echo {} > /proc/acpi/wakeup'
We should see a patch by the time kernel 3.17 comes out later this year.
For now, I would try kernel 3.16. Update available http://download.opensuse.org/repositories/Kernel:/HEAD/standard/
