 235           Overriding LED state on ThinkPads can mask important

 238           the bay while buses are still active), etc.
 239
 240           LED control on the ThinkPad is write-only (with very few
 241           exceptions on very ancient models), which makes it

 303           need to do NVRAM polling to support any of the hot keys you use,
 304           unselecting this option will save about 1kB of memory.
 305
 306           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 307           unlikely to need NVRAM polling in their latest BIOS versions.
 308
 309           NVRAM polling can detect at most the following keys: ThinkPad/Access

 347
 348           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 349           ACPI firmware to userspace - this is done through various vendor
 350           defined methods and data blocks in a PNP0C14 device, which are then
 351           made available for userspace to call.
 352
 353           The implementation of this in Linux currently only exposes this to
 354           other kernel space drivers.
 355
 356           This driver is a required dependency to build the firmware specific
 357           drivers needed on many machines, including Acer and HP laptops.

 373           and most importantly, allows you to blink those fancy LEDs intended
 374           for reporting mail and wireless status.
 375
 376           Note: display switching code is currently considered EXPERIMENTAL,
 377           toying with these values may even lock your machine.

 407           On these machines, all system configuration is handled through the
 408           ACPI.  This driver is required for access to controls not covered
 409           by the general ACPI drivers, such as LCD brightness, video output,
 410           etc.

 412           This driver differs from the non-ACPI Toshiba laptop driver (located
 413           under "Processor type and features") in several aspects.
 414           Configuration is accessed by reading and writing text files in the
 415           /proc tree instead of by program interface to /dev.  Furthermore, no
 416           power management functions are exposed, as those are handled by the
 417           general ACPI drivers.
