 422           Overriding LED state on ThinkPads can mask important

 424           the user into damaging the hardware (undocking or ejecting
 425           the bay while buses are still active), etc.
 426
 427           LED control on the ThinkPad is write-only (with very few
 428           exceptions on very ancient models), which makes it
 429           impossible to know beforehand if important information will
 430           be lost when one changes LED state.
 431
 432           Users that know what they are doing can enable this option
 433           and the driver will allow control of every LED, including
 434           the ones on the dock stations.

 453           your ThinkPad's video output ports instead of this feature,
 454           don't think twice: do it and say N here to save memory and avoid
 455           bad interactions with X.org.
 456
 457           NOTE: access to this feature is limited to processes with the
 458           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 459           where it interacts badly with X.org.

 469           Some thinkpad models benefit from NVRAM polling to detect a few of
 470           the hot key press events.  If you know your ThinkPad model does not
 471           need to do NVRAM polling to support any of the hot keys you use,

 474           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 475           unlikely to need NVRAM polling in their latest BIOS versions.
 476
 477           NVRAM polling can detect at most the following keys: ThinkPad/Access

 587           ACPI-WMI is a proprietary extension to ACPI to expose parts of the

 874           This driver provides support for modifying paramaters on systems
 875           equipped with Intel's Rapid Start Technology. When put in an ACPI
 876           sleep state, these devices will wake after either a configured
 877           timeout or when the system battery reaches a critical state,
 878           automatically copying memory contents to disk. On resume, the
 879           firmware will copy the memory contents back to RAM and resume the OS

 886           Intel Smart Connect is a technology intended to permit devices to
 887           update state by resuming for a short period of time at regular
 888           intervals. If a user enables this functionality under Windows and
 889           then reboots into Linux, the system may remain configured to resume
 890           on suspend. In the absence of any userspace to support it, the system
 891           will then remain awake until something triggers another suspend.
 892
 893           This driver checks to determine whether the device has Intel Smart
 894           Connect enabled, and if so disables it.
