 262           Overriding LED state on ThinkPads can mask important
 263           firmware alerts (like critical battery condition), or misled
 264           the user into damaging the hardware (undocking or ejecting
 265           the bay while buses are still active), etc.
 266
 267           LED control on the ThinkPad is write-only (with very few
 268           exceptions on very ancient models), which makes it
 269           impossible to know beforehand if important information will
 270           be lost when one changes LED state.
 271
 272           Users that know what they are doing can enable this option
 273           and the driver will allow control of every LED, including

 291           server running, phase of the moon, and the current mood of
 292           Schroedinger's cat.  If you can use X.org's RandR to control

 304           the hot key press events.  If you know your ThinkPad model does not
 305           need to do NVRAM polling to support any of the hot keys you use,
 306           unselecting this option will save about 1kB of memory.
 307
 308           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 309           unlikely to need NVRAM polling in their latest BIOS versions.
 310
 311           NVRAM polling can detect at most the following keys: ThinkPad/Access

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

 353
 354           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 355           ACPI firmware to userspace - this is done through various vendor
 356           defined methods and data blocks in a PNP0C14 device, which are then
 357           made available for userspace to call.
 358
 359           The implementation of this in Linux currently only exposes this to
 360           other kernel space drivers.
 361
 362           This driver is a required dependency to build the firmware specific
 363           drivers needed on many machines, including Acer and HP laptops.

 376           the extra buttons generate standard ACPI events that go through
 377           /proc/acpi/events, and (on some models) adds support for changing the
 378           display brightness and output, switching the LCD backlight on and off,
 379           and most importantly, allows you to blink those fancy LEDs intended
 380           for reporting mail and wireless status.
 381
 382           Note: display switching code is currently considered EXPERIMENTAL,
 383           toying with these values may even lock your machine.
 384
 385           All settings are changed via /proc/acpi/asus directory entries. Owner

 417           This driver adds support for access to certain system settings
 418           on "legacy free" Toshiba laptops.  These laptops can be recognized by
 419           their lack of a BIOS setup menu and APM support.
 420
 421           On these machines, all system configuration is handled through the
 422           ACPI.  This driver is required for access to controls not covered
 423           by the general ACPI drivers, such as LCD brightness, video output,
 424           etc.
 425
 426           This driver differs from the non-ACPI Toshiba laptop driver (located
 427           under "Processor type and features") in several aspects.
 428           Configuration is accessed by reading and writing text files in the
 429           /proc tree instead of by program interface to /dev.  Furthermore, no
 430           power management functions are exposed, as those are handled by the
 431           general ACPI drivers.

 436           If you have a legacy free Toshiba laptop (such as the Libretto L1
 437           series), say Y.
