 357
 358           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 359           with a single read-only mixer control, which should be used for
 360           on-screen-display feedback purposes by the Desktop Environment.
 361
 362           Optionally, the driver will also allow software control (the
 363           ALSA mixer will be made read-write).  Please refer to the driver
 364           documentation for details.
 365
 366           All IBM models have both volume and mute control.  Newer Lenovo
 367           models only have mute control (the volume hotkeys are just normal
 368           keys and volume control is done through the main HDA mixer).

 398           the user into damaging the hardware (undocking or ejecting
 399           the bay while buses are still active), etc.
 400
 401           LED control on the ThinkPad is write-only (with very few
 402           exceptions on very ancient models), which makes it
 403           impossible to know beforehand if important information will
 404           be lost when one changes LED state.
 405
 406           Users that know what they are doing can enable this option
 407           and the driver will allow control of every LED, including
 408           the ones on the dock stations.

 443           Some thinkpad models benefit from NVRAM polling to detect a few of
 444           the hot key press events.  If you know your ThinkPad model does not
 445           need to do NVRAM polling to support any of the hot keys you use,
 446           unselecting this option will save about 1kB of memory.
 447
 448           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 449           unlikely to need NVRAM polling in their latest BIOS versions.
 450
 451           NVRAM polling can detect at most the following keys: ThinkPad/Access
 452           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 453           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 560
 561           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 562           ACPI firmware to userspace - this is done through various vendor
 563           defined methods and data blocks in a PNP0C14 device, which are then
 564           made available for userspace to call.
 565
 566           The implementation of this in Linux currently only exposes this to
 567           other kernel space drivers.
 568
 569           This driver is a required dependency to build the firmware specific
 570           drivers needed on many machines, including Acer and HP laptops.

 621           Configuration is accessed by reading and writing text files in the

 814           Intel Smart Connect is a technology intended to permit devices to
 815           update state by resuming for a short period of time at regular
 816           intervals. If a user enables this functionality under Windows and
 817           then reboots into Linux, the system may remain configured to resume
 818           on suspend. In the absence of any userspace to support it, the system
 819           will then remain awake until something triggers another suspend.

 821           This driver checks to determine whether the device has Intel Smart
 822           Connect enabled, and if so disables it.
