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

 330
 331           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 332           with a single read-only mixer control, which should be used for
 333           on-screen-display feedback purposes by the Desktop Environment.

 337           documentation for details.
 338
 339           All IBM models have both volume and mute control.  Newer Lenovo

 369           Overriding LED state on ThinkPads can mask important

 371           the user into damaging the hardware (undocking or ejecting
 372           the bay while buses are still active), etc.
 373
 374           LED control on the ThinkPad is write-only (with very few
 375           exceptions on very ancient models), which makes it
 376           impossible to know beforehand if important information will
 377           be lost when one changes LED state.
 378
 379           Users that know what they are doing can enable this option
 380           and the driver will allow control of every LED, including
 381           the ones on the dock stations.
 382
 383           Never enable this option on a distribution kernel.

 402           bad interactions with X.org.
 403
 404           NOTE: access to this feature is limited to processes with the
 405           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 406           where it interacts badly with X.org.

 416           Some thinkpad models benefit from NVRAM polling to detect a few of
 417           the hot key press events.  If you know your ThinkPad model does not
 418           need to do NVRAM polling to support any of the hot keys you use,
 419           unselecting this option will save about 1kB of memory.
 420
 421           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 422           unlikely to need NVRAM polling in their latest BIOS versions.
 423
 424           NVRAM polling can detect at most the following keys: ThinkPad/Access
 425           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 426           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 429           it is strictly necessary to do so.

 532
 533           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 534           ACPI firmware to userspace - this is done through various vendor
 535           defined methods and data blocks in a PNP0C14 device, which are then
 536           made available for userspace to call.
 537
 538           The implementation of this in Linux currently only exposes this to
 539           other kernel space drivers.
 540
 541           This driver is a required dependency to build the firmware specific
 542           drivers needed on many machines, including Acer and HP laptops.

 584
 585           On these machines, all system configuration is handled through the
 586           ACPI.  This driver is required for access to controls not covered
 587           by the general ACPI drivers, such as LCD brightness, video output,
 588           etc.
 589
 590           This driver differs from the non-ACPI Toshiba laptop driver (located
 591           under "Processor type and features") in several aspects.
 592           Configuration is accessed by reading and writing text files in the
 593           /proc tree instead of by program interface to /dev.  Furthermore, no
 594           power management functions are exposed, as those are handled by the
