 284           For more information about this driver see

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

 307
 308           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 309           with a single read-only mixer control, which should be used for
 310           on-screen-display feedback purposes by the Desktop Environment.

 314           documentation for details.
 315
 316           All IBM models have both volume and mute control.  Newer Lenovo

 346           Overriding LED state on ThinkPads can mask important

 349           the bay while buses are still active), etc.
 350
 351           LED control on the ThinkPad is write-only (with very few
 352           exceptions on very ancient models), which makes it
 353           impossible to know beforehand if important information will
 354           be lost when one changes LED state.
 355
 356           Users that know what they are doing can enable this option
 357           and the driver will allow control of every LED, including
 358           the ones on the dock stations.
 359
 360           Never enable this option on a distribution kernel.
 361

 373           This feature often won't work well, depending on ThinkPad model,
 374           display state, video output devices in use, whether there is a X
 375           server running, phase of the moon, and the current mood of
 376           Schroedinger's cat.  If you can use X.org's RandR to control
 377           your ThinkPad's video output ports instead of this feature,
 378           don't think twice: do it and say N here to save memory and avoid
 379           bad interactions with X.org.
 380
 381           NOTE: access to this feature is limited to processes with the
 382           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 383           where it interacts badly with X.org.

 393           Some thinkpad models benefit from NVRAM polling to detect a few of

 395           need to do NVRAM polling to support any of the hot keys you use,
 396           unselecting this option will save about 1kB of memory.
 397
 398           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 399           unlikely to need NVRAM polling in their latest BIOS versions.
 400
 401           NVRAM polling can detect at most the following keys: ThinkPad/Access

 511
 512           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 513           ACPI firmware to userspace - this is done through various vendor
 514           defined methods and data blocks in a PNP0C14 device, which are then
 515           made available for userspace to call.
 516
 517           The implementation of this in Linux currently only exposes this to
 518           other kernel space drivers.
 519
 520           This driver is a required dependency to build the firmware specific
 521           drivers needed on many machines, including Acer and HP laptops.

 549           and most importantly, allows you to blink those fancy LEDs intended
 550           for reporting mail and wireless status.
