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

 319           Note that if you want ThinkPad-ACPI to be built-in instead of

 334
 335           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 336           with a single read-only mixer control, which should be used for
 337           on-screen-display feedback purposes by the Desktop Environment.

 341           documentation for details.
 342
 343           All IBM models have both volume and mute control.  Newer Lenovo

 373           Overriding LED state on ThinkPads can mask important

 375           the user into damaging the hardware (undocking or ejecting
 376           the bay while buses are still active), etc.
 377
 378           LED control on the ThinkPad is write-only (with very few
 379           exceptions on very ancient models), which makes it
 380           impossible to know beforehand if important information will
 381           be lost when one changes LED state.
 382
 383           Users that know what they are doing can enable this option
 384           and the driver will allow control of every LED, including
 385           the ones on the dock stations.
 386
 387           Never enable this option on a distribution kernel.

 420           Some thinkpad models benefit from NVRAM polling to detect a few of
 421           the hot key press events.  If you know your ThinkPad model does not
 422           need to do NVRAM polling to support any of the hot keys you use,
 423           unselecting this option will save about 1kB of memory.
 424
 425           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 426           unlikely to need NVRAM polling in their latest BIOS versions.
 427
 428           NVRAM polling can detect at most the following keys: ThinkPad/Access
 429           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 430           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 536
 537           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 538           ACPI firmware to userspace - this is done through various vendor
 539           defined methods and data blocks in a PNP0C14 device, which are then
 540           made available for userspace to call.
 541
 542           The implementation of this in Linux currently only exposes this to
 543           other kernel space drivers.
 544
 545           This driver is a required dependency to build the firmware specific
 546           drivers needed on many machines, including Acer and HP laptops.

 593
 594           This driver differs from the non-ACPI Toshiba laptop driver (located
 595           under "Processor type and features") in several aspects.
 596           Configuration is accessed by reading and writing text files in the
 597           /proc tree instead of by program interface to /dev.  Furthermore, no
