 64           MEDION, JVC or VICTOR laptops. It makes all the extra buttons generate
 65           standard ACPI events and input events. It also adds
 66           support for video output switching, LCD backlight control, Bluetooth and
 67           Wlan control, and most importantly, allows you to blink those fancy LEDs.

229           <> .
231           This driver was formerly known as ibm-acpi.

243           Say N here, unless you were told by a kernel maintainer to do

250         ---help---
251           Enables extra debugging information, at the expense of a slightly
252           increase in driver size.
254           If you are not sure, say N here.
257         bool "Allow control of important LEDs (unsafe)"
258         depends on THINKPAD_ACPI
259         default n
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.
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.
271           Users that know what they are doing can enable this option
272           and the driver will allow control of every LED, including
273           the ones on the dock stations.
275           Never enable this option on a distribution kernel.
277           Say N here, unless you are building a kernel for your own
278           use, and need to control the important firmware LEDs.

285           Allows the thinkpad_acpi driver to provide an interface to control
286           the various video output ports.
288           This feature often won't work well, depending on ThinkPad model,
289           display state, video output devices in use, whether there is a X
290           server running, phase of the moon, and the current mood of
291           Schroedinger's cat.  If you can use's RandR to control
292           your ThinkPad's video output ports instead of this feature,
293           don't think twice: do it and say N here to save some memory.
295           If you are not sure, say Y here.

299         depends on THINKPAD_ACPI
300         default y
301         ---help---
302           Some thinkpad models benefit from NVRAM polling to detect a few of
303           the hot key press events.  If you know your ThinkPad model does not
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.
307           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
308           unlikely to need NVRAM polling in their latest BIOS versions.
310           NVRAM polling can detect at most the following keys: ThinkPad/Access
311           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
312           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
314           If you are not sure, say Y here.  The driver enables polling only if
315           it is strictly necessary to do so.

350           This driver adds support for the ACPI-WMI (Windows Management
351           Instrumentation) mapper device (PNP0C14) found on some systems.
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.
358           The implementation of this in Linux currently only exposes this to
359           other kernel space drivers.
361           This driver is a required dependency to build the firmware specific
362           drivers needed on many machines, including Acer and HP laptops.
364           It is safe to enable this driver even if your DSDT doesn't define

372           This driver provides support for extra features of ACPI-compatible
373           ASUS laptops. As some of Medion laptops are made by ASUS, it may also
374           support some Medion laptops (such as 9675 for example).  It makes all
375           the extra buttons generate standard ACPI events that go through
376           /proc/acpi/events, and (on some models) adds support for changing the
377           display brightness and output, switching the LCD backlight on and off,
378           and most importantly, allows you to blink those fancy LEDs intended
379           for reporting mail and wireless status.
381           Note: display switching code is currently considered EXPERIMENTAL,
382           toying with these values may even lock your machine.
384           All settings are changed via /proc/acpi/asus directory entries. Owner
385           and group for these entries can be set with asus_uid and asus_gid
386           parameters.

392           driver is still under development, so if your laptop is unsupported or

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.
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.
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.
423           More information about this driver is available at
424           <>.
426           If you have a legacy free Toshiba laptop (such as the Libretto L1
