>Description:
	When you close the lid on a HP nx6125 in VTY mode, the whole system
	pauses for almost exactly one second.  There is also a short pause
	when you open the lid.  This does not occur when running in X11
	mode with X.org 7.3 but occasionally occurs when switching between
	VTY and X11 modes.

	Relevant sysctl:
hw.acpi.supported_sleep_state: S3 S4 S5
hw.acpi.power_button_state: NONE
hw.acpi.sleep_button_state: S3
hw.acpi.lid_switch_state: NONE
hw.acpi.standby_state: S1
hw.acpi.suspend_state: S3
hw.acpi.sleep_delay: 1
hw.acpi.s4bios: 1
hw.acpi.verbose: 0
hw.acpi.disable_on_reboot: 0
hw.acpi.handle_reboot: 0
hw.acpi.cpu.cx_lowest: C1

>How-To-Repeat:
	Run "dd if=/dev/ad0 of=/dev/null" or similar to make HDD light go
	on and then close the lid.  The HDD light will go out for 1 second
	before continuing.

	Allow some time for NTP to poll.  "ntpq -p" will show a 1 second offset
