 422
 423           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 424           with a single read-only mixer control, which should be used for
 425           on-screen-display feedback purposes by the Desktop Environment.
 426

 429           documentation for details.
 430
 431           All IBM models have both volume and mute control.  Newer Lenovo
 432           models only have mute control (the volume hotkeys are just normal

 461           Overriding LED state on ThinkPads can mask important

 464           the bay while buses are still active), etc.
 465
 466           LED control on the ThinkPad is write-only (with very few
 467           exceptions on very ancient models), which makes it
 468           impossible to know beforehand if important information will
 469           be lost when one changes LED state.

 472           and the driver will allow control of every LED, including
 473           the ones on the dock stations.

 495
 496           NOTE: access to this feature is limited to processes with the

 510           need to do NVRAM polling to support any of the hot keys you use,

 513           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 514           unlikely to need NVRAM polling in their latest BIOS versions.
 515
 516           NVRAM polling can detect at most the following keys: ThinkPad/Access

 518           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 643
 644           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 645           ACPI firmware to userspace - this is done through various vendor
 646           defined methods and data blocks in a PNP0C14 device, which are then
 647           made available for userspace to call.
