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

 304           need to do NVRAM polling to support any of the hot keys you use,
 305           unselecting this option will save about 1kB of memory.
 306
 307           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 308           unlikely to need NVRAM polling in their latest BIOS versions.

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

 352
 353           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 354           ACPI firmware to userspace - this is done through various vendor
 355           defined methods and data blocks in a PNP0C14 device, which are then
 356           made available for userspace to call.
 357
 358           The implementation of this in Linux currently only exposes this to
 359           other kernel space drivers.
 360
 361           This driver is a required dependency to build the firmware specific
 362           drivers needed on many machines, including Acer and HP laptops.

 375           the extra buttons generate standard ACPI events that go through
 376           /proc/acpi/events, and (on some models) adds support for changing the

 378           and most importantly, allows you to blink those fancy LEDs intended
 379           for reporting mail and wireless status.
 380
 381           Note: display switching code is currently considered EXPERIMENTAL,
 382           toying with these values may even lock your machine.

 407           This driver adds support for access to certain system settings
 408           on "legacy free" Toshiba laptops.  These laptops can be recognized by
 409           their lack of a BIOS setup menu and APM support.
 410
 411           On these machines, all system configuration is handled through the
 412           ACPI.  This driver is required for access to controls not covered
 413           by the general ACPI drivers, such as LCD brightness, video output,
 414           etc.
 415
 416           This driver differs from the non-ACPI Toshiba laptop driver (located
 417           under "Processor type and features") in several aspects.
 418           Configuration is accessed by reading and writing text files in the
 419           /proc tree instead of by program interface to /dev.  Furthermore, no
 420           power management functions are exposed, as those are handled by the
 421           general ACPI drivers.
 422

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