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

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

 372           Overriding LED state on ThinkPads can mask important

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

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

 535
 536           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 537           ACPI firmware to userspace - this is done through various vendor
 538           defined methods and data blocks in a PNP0C14 device, which are then
 539           made available for userspace to call.
 540
 541           The implementation of this in Linux currently only exposes this to
 542           other kernel space drivers.
 543
 544           This driver is a required dependency to build the firmware specific
 545           drivers needed on many machines, including Acer and HP laptops.

 594           under "Processor type and features") in several aspects.
 595           Configuration is accessed by reading and writing text files in the
 596           /proc tree instead of by program interface to /dev.  Furthermore, no
