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

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

 374           Overriding LED state on ThinkPads can mask important

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

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

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

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