 283           This driver was formerly known as ibm-acpi.

 285           Extra functionality will be available if the rfkill (CONFIG_RFKILL)

 287           Note that if you want ThinkPad-ACPI to be built-in instead of
 288           modular, ALSA and rfkill will also have to be built-in.

 302
 303           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 304           with a single read-only mixer control, which should be used for
 305           on-screen-display feedback purposes by the Desktop Environment.
 306
 307           Optionally, the driver will also allow software control (the

 309           documentation for details.
 310
 311           All IBM models have both volume and mute control.  Newer Lenovo

 341           Overriding LED state on ThinkPads can mask important

 344           the bay while buses are still active), etc.
 345
 346           LED control on the ThinkPad is write-only (with very few
 347           exceptions on very ancient models), which makes it
 348           impossible to know beforehand if important information will
 349           be lost when one changes LED state.
 350
 351           Users that know what they are doing can enable this option
 352           and the driver will allow control of every LED, including
 353           the ones on the dock stations.
 354
 355           Never enable this option on a distribution kernel.

 370           server running, phase of the moon, and the current mood of
 371           Schroedinger's cat.  If you can use X.org's RandR to control
 372           your ThinkPad's video output ports instead of this feature,
 373           don't think twice: do it and say N here to save memory and avoid
 374           bad interactions with X.org.
 375
 376           NOTE: access to this feature is limited to processes with the
 377           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 378           where it interacts badly with X.org.

 388           Some thinkpad models benefit from NVRAM polling to detect a few of
 389           the hot key press events.  If you know your ThinkPad model does not
 390           need to do NVRAM polling to support any of the hot keys you use,
 391           unselecting this option will save about 1kB of memory.
 392
 393           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 394           unlikely to need NVRAM polling in their latest BIOS versions.
 395
 396           NVRAM polling can detect at most the following keys: ThinkPad/Access
 397           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 398           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
 399

 506
 507           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 508           ACPI firmware to userspace - this is done through various vendor
 509           defined methods and data blocks in a PNP0C14 device, which are then
 510           made available for userspace to call.
 511
 512           The implementation of this in Linux currently only exposes this to
 513           other kernel space drivers.
 514
 515           This driver is a required dependency to build the firmware specific
 516           drivers needed on many machines, including Acer and HP laptops.

 541           the extra buttons generate standard ACPI events that go through
 542           /proc/acpi/events, and (on some models) adds support for changing the

 544           and most importantly, allows you to blink those fancy LEDs intended
 545           for reporting mail and wireless status.

 590           On these machines, all system configuration is handled through the
