	  Overriding LED state on ThinkPads can mask important

	  the bay while buses are still active), etc.

	  LED control on the ThinkPad is write-only (with very few
	  exceptions on very ancient models), which makes it
	  impossible to know beforehand if important information will
	  be lost when one changes LED state.

	  and the driver will allow control of every LED, including
	  the ones on the dock stations.

	  Never enable this option on a distribution kernel.

	  use, and need to control the important firmware LEDs.

	  Some thinkpad models benefit from NVRAM polling to detect a few of

	  need to do NVRAM polling to support any of the hot keys you use,
	  unselecting this option will save about 1kB of memory.

	  ThinkPads T40 and newer, R52 and newer, and X31 and newer are
	  unlikely to need NVRAM polling in their latest BIOS versions.

	  NVRAM polling can detect at most the following keys: ThinkPad/Access

	  Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

	 state = 0 (BIOS SMIs on)
	 state = 1 (BIOS SMIs off)

	  Intel Smart Connect is a technology intended to permit devices to

	  on suspend. In the absence of any userspace to support it, the system
	  will then remain awake until something triggers another suspend.

	  This driver checks to determine whether the device has Intel Smart
	  Connect enabled, and if so disables it.
