 277           Some thinkpad models benefit from NVRAM polling to detect a few of
 278           the hot key press events.  If you know your ThinkPad model does not
 279           need to do NVRAM polling to support any of the hot keys you use,
 280           unselecting this option will save about 1kB of memory.
 281
 282           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 283           unlikely to need NVRAM polling in their latest BIOS versions.
 284
 285           NVRAM polling can detect at most the following keys: ThinkPad/Access
 286           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 287           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 323
 324           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 325           ACPI firmware to userspace - this is done through various vendor
 326           defined methods and data blocks in a PNP0C14 device, which are then
 327           made available for userspace to call.
 328
 329           The implementation of this in Linux currently only exposes this to
 330           other kernel space drivers.
 331
 332           This driver is a required dependency to build the firmware specific
 333           drivers needed on many machines, including Acer and HP laptops.

 343           This driver provides support for extra features of ACPI-compatible

 346           the extra buttons generate standard ACPI events that go through
 347           /proc/acpi/events, and (on some models) adds support for changing the
 348           display brightness and output, switching the LCD backlight on and off,
 349           and most importantly, allows you to blink those fancy LEDs intended
 350           for reporting mail and wireless status.
 351
 352           Note: display switching code is currently considered EXPERIMENTAL,
 353           toying with these values may even lock your machine.

 381           their lack of a BIOS setup menu and APM support.
 382
 383           On these machines, all system configuration is handled through the
 384           ACPI.  This driver is required for access to controls not covered
 385           by the general ACPI drivers, such as LCD brightness, video output,
 386           etc.
 387
 388           This driver differs from the non-ACPI Toshiba laptop driver (located
 389           under "Processor type and features") in several aspects.
 390           Configuration is accessed by reading and writing text files in the
 391           /proc tree instead of by program interface to /dev.  Furthermore, no
 392           power management functions are exposed, as those are handled by the
 393           general ACPI drivers.
