 430           Overriding LED state on ThinkPads can mask important

 433           the bay while buses are still active), etc.
 434
 435           LED control on the ThinkPad is write-only (with very few
 436           exceptions on very ancient models), which makes it
 437           impossible to know beforehand if important information will
 438           be lost when one changes LED state.

 441           and the driver will allow control of every LED, including

 464
 465           NOTE: access to this feature is limited to processes with the

 479           need to do NVRAM polling to support any of the hot keys you use,

 483           unlikely to need NVRAM polling in their latest BIOS versions.

 885           This driver provides support for modifying paramaters on systems
 886           equipped with Intel's Rapid Start Technology. When put in an ACPI
 887           sleep state, these devices will wake after either a configured
 888           timeout or when the system battery reaches a critical state,
 889           automatically copying memory contents to disk. On resume, the

 897           Intel Smart Connect is a technology intended to permit devices to
 898           update state by resuming for a short period of time at regular
 899           intervals. If a user enables this functionality under Windows and
 900           then reboots into Linux, the system may remain configured to resume
 901           on suspend. In the absence of any userspace to support it, the system
 902           will then remain awake until something triggers another suspend.
 903
 904           This driver checks to determine whether the device has Intel Smart
 905           Connect enabled, and if so disables it.
