I'd like to trim wakeup events of my laptop. Could someone please explain me these 4 letter codes - which devices do they actually represent?
$ cat /proc/acpi/wakeup Device S-state Status Sysfs node LID S4 *enabled platform:PNP0C0D:00 SLPB S3 *enabled platform:PNP0C0E:00 IGBE S4 *enabled pci:0000:00:19.0 EXP3 S4 *disabled pci:0000:00:1c.2 XHCI S3 *enabled pci:0000:00:14.0 EHC1 S3 *enabled pci:0000:00:1d.0 EHC2 S3 *enabled pci:0000:00:1a.0 HDEF S4 *disabled pci:0000:00:1b.0
I have documented some findings as an answer below. Seems that now only IGBE and HDEF are lacking from the picture.
