Prevent all wakeups except lid

Hello,

I've had issues with echi_hcd and xhci_hcd preventing sleep, so I wrote a /usr/lib/systemd/system-sleep script to rmmod/modprobe them on sleep. This has worked okay except today my laptop started and ran for 2 hours while in it's laptop bag. It was very hot once I noticed.

I'd like a way to prevent anything at all from waking the laptop while the lid is closed.

I've looked at /proc/acpi/wakeup and disable the two items there:

Device	S-state	  Status   Sysfs node
P0P1	  S4	*disabled
GLAN	  S4	*disabled
EHC1	  S3	*disabled  pci:0000:00:1d.0
EHC2	  S4	*disabled
XHC	  S3	*disabled  pci:0000:00:14.0
HDEF	  S4	*disabled  pci:0000:00:1b.0
RP01	  S3	*disabled  pci:0000:00:1c.0
PXSX	  S3	*disabled  pci:0000:01:00.0
PEG0	  S4	*disabled
PEGP	  S4	*disabled
PEG1	  S4	*disabled
PEG2	  S4	*disabled

Still when I 'systemctl suspend' the system I can wake it with any keyboard key.

Can anyone tell me how to prevent the laptop from running while the lid is closed.

As a secondary query, I'd also like to know if there's some way to get a log of why the system actually awoke. It doesn't seem to be kept anywhere so I'd like to know how to enable these logs.

Thank you.

You might have to change the files in /sys/bus/usb/devices/*/power/wakeup from 'enabled' to 'disabled'.

Re: Prevent all wakeups except lid

Thanks, I tried that, but the keyboard can still wake the machine while closed. The screen is also a touchpad and I'm not sure if that'll wake it either.
