Thanks for the link.

/proc/acpi/wakeup contains:

Device	S-state	  Status   Sysfs node
P32	  S4	 disabled  pci:0000:00:1e.0
UHC1	  S3	 disabled  pci:0000:00:1d.0
UHC2	  S3	 disabled  pci:0000:00:1d.1
UHC3	  S3	 disabled  pci:0000:00:1d.2

ECHI	  S3	 disabled  pci:0000:00:1d.7
EXP1	  S4	 disabled  pci:0000:00:1c.0
EXP2	  S4	 disabled  pci:0000:00:1c.1

EXP4	  S4	 disabled  pci:0000:00:1c.3
AZAL	  S0	 disabled  pci:0000:00:1b.0
MODM	  S0	 disabled  

there's nothing identifiable as a lid device, and nothing is enabled.

I've filed to track this, and we
can figure out there whether this is a bug or not.
