After a recent update I've noticed that when I close the lid on my laptop and the system suspends that when I re-open the lid and the system restores non of my power management features work. The backlight is dim and closing the lid again will not suspend the system. The only way to get around this is to open the power management settings which seems to reset the APM system because the sreen brightness immediately adjusts and I'm able to suspend again. Of course rebooting solves this as well. I've checked the log and the only thing I can see after returning from a suspended session that looks suspicious is this:
pcieport 0000:00:04.0: wake-up capability disabled by ACPI
Has anyone else experienced this problem?
