 286           Some thinkpad models benefit from NVRAM polling to detect a few of
 287           the hot key press events.  If you know your ThinkPad model does not
 288           need to do NVRAM polling to support any of the hot keys you use,
 289           unselecting this option will save about 1kB of memory.
 290
 291           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 292           unlikely to need NVRAM polling in their latest BIOS versions.
 293
 294           NVRAM polling can detect at most the following keys: ThinkPad/Access
 295           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 296           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 332
 333           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 334           ACPI firmware to userspace - this is done through various vendor
 335           defined methods and data blocks in a PNP0C14 device, which are then
 336           made available for userspace to call.
 337
 338           The implementation of this in Linux currently only exposes this to
 339           other kernel space drivers.
 340
 341           This driver is a required dependency to build the firmware specific
 342           drivers needed on many machines, including Acer and HP laptops.

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

 354           support some Medion laptops (such as 9675 for example).  It makes all
 355           the extra buttons generate standard ACPI events that go through
 356           /proc/acpi/events, and (on some models) adds support for changing the
 357           display brightness and output, switching the LCD backlight on and off,
 358           and most importantly, allows you to blink those fancy LEDs intended
 359           for reporting mail and wireless status.
 360
 361           Note: display switching code is currently considered EXPERIMENTAL,
 362           toying with these values may even lock your machine.
 363
 364           All settings are changed via /proc/acpi/asus directory entries. Owner

 390           their lack of a BIOS setup menu and APM support.
 391
 392           On these machines, all system configuration is handled through the
 393           ACPI.  This driver is required for access to controls not covered
 394           by the general ACPI drivers, such as LCD brightness, video output,
 395           etc.
 396
 397           This driver differs from the non-ACPI Toshiba laptop driver (located
 398           under "Processor type and features") in several aspects.
 399           Configuration is accessed by reading and writing text files in the
 400           /proc tree instead of by program interface to /dev.  Furthermore, no
 401           power management functions are exposed, as those are handled by the
 402           general ACPI drivers.
