 367
 368           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 369           with a single read-only mixer control, which should be used for
 370           on-screen-display feedback purposes by the Desktop Environment.
 371
 372           Optionally, the driver will also allow software control (the

 374           documentation for details.
 375
 376           All IBM models have both volume and mute control.  Newer Lenovo
 377           models only have mute control (the volume hotkeys are just normal
 378           keys and volume control is done through the main HDA mixer).

 409           the bay while buses are still active), etc.
 410
 411           LED control on the ThinkPad is write-only (with very few
 412           exceptions on very ancient models), which makes it
 413           impossible to know beforehand if important information will
 414           be lost when one changes LED state.
 415
 416           Users that know what they are doing can enable this option
 417           and the driver will allow control of every LED, including
 418           the ones on the dock stations.
 419
 420           Never enable this option on a distribution kernel.

 434           display state, video output devices in use, whether there is a X
 435           server running, phase of the moon, and the current mood of
 436           Schroedinger's cat.  If you can use X.org's RandR to control
 437           your ThinkPad's video output ports instead of this feature,
 438           don't think twice: do it and say N here to save memory and avoid
 439           bad interactions with X.org.
 440
 441           NOTE: access to this feature is limited to processes with the
 442           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 443           where it interacts badly with X.org.

 453           Some thinkpad models benefit from NVRAM polling to detect a few of
 454           the hot key press events.  If you know your ThinkPad model does not
 455           need to do NVRAM polling to support any of the hot keys you use,
 456           unselecting this option will save about 1kB of memory.
 457
 458           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 459           unlikely to need NVRAM polling in their latest BIOS versions.
 460
 461           NVRAM polling can detect at most the following keys: ThinkPad/Access
 462           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 463           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 570
 571           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 572           ACPI firmware to userspace - this is done through various vendor
 573           defined methods and data blocks in a PNP0C14 device, which are then
 574           made available for userspace to call.
 575
 576           The implementation of this in Linux currently only exposes this to
 577           other kernel space drivers.
 578
 579           This driver is a required dependency to build the firmware specific
 580           drivers needed on many machines, including Acer and HP laptops.

 857           This driver provides support for modifying paramaters on systems
 858           equipped with Intel's Rapid Start Technology. When put in an ACPI
 859           sleep state, these devices will wake after either a configured
 860           timeout or when the system battery reaches a critical state,
 861           automatically copying memory contents to disk. On resume, the
 862           firmware will copy the memory contents back to RAM and resume the OS
 863           as usual.

 869           Intel Smart Connect is a technology intended to permit devices to
 870           update state by resuming for a short period of time at regular
 871           intervals. If a user enables this functionality under Windows and
 872           then reboots into Linux, the system may remain configured to resume
 873           on suspend. In the absence of any userspace to support it, the system
 874           will then remain awake until something triggers another suspend.
 875
 876           This driver checks to determine whether the device has Intel Smart
 877           Connect enabled, and if so disables it.
