If you know your ThinkPad model does not 312 need to do NVRAM polling to support any of the hot keys you use, 313 unselecting this option will save about 1kB of memory. 314 315 ThinkPads T40 and newer, R52 and newer, and X31 and newer are 316 unlikely to need NVRAM polling in their latest BIOS versions. 317 318 NVRAM polling can detect at most the following keys: ThinkPad/Access 319 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute, 320 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12). 321 322 If you are not sure, say Y here.

As some of Medion laptops are made by ASUS, it may also 378 support some Medion laptops (such as 9675 for example). It makes all 379 the extra buttons generate standard ACPI events that go through 380 /proc/acpi/events, and (on some models) adds support for changing the 381 display brightness and output, switching the LCD backlight on and off, 382 and most importantly, allows you to blink those fancy LEDs intended 383 for reporting mail and wireless status. 384 385 Note: display switching code is currently considered EXPERIMENTAL, 386 toying with these values may even lock your machine. 387 388 All settings are changed via /proc/acpi/asus directory entries. Owner 389 and group for these entries can be set with asus_uid and asus_gid 390 parameters. 391 392 More information and a userspace daemon for handling the extra buttons 393 at <http://sourceforge.net/projects/acpi4asus/>. 394 395 If you have an ACPI-compatible ASUS laptop, say Y or M here. This 396 driver is still under development, so if your laptop is unsupported or 397 something works not quite as expected, please use the mailing list 398 available on the above page (acpi4asus-user@lists.sourceforge.net). 399 400 NOTE: This driver is deprecated and will probably be removed soon, 401 use asus-laptop instead. 402 403config ACPI_TOSHIBA 404 tristate "Toshiba Laptop Extras" 405 depends on ACPI 406 depends on INPUT 407 depends on RFKILL || RFKILL = n 408 select INPUT_POLLDEV 409 select BACKLIGHT_CLASS_DEVICE 410 ---help--- 411 This driver adds support for access to certain system settings 412 on "legacy free" Toshiba laptops. These laptops can be recognized by 413 their lack of a BIOS setup menu and APM support. 414 415 On these machines, all system configuration is handled through the 416 ACPI. This driver is required for access to controls not covered 417 by the general ACPI drivers, such as LCD brightness, video output, 418 etc. 419 420 This driver differs from the non-ACPI Toshiba laptop driver (located 421 under "Processor type and features") in several aspects. 422 Configuration is accessed by reading and writing text files in the 423 /proc tree instead of by program interface to /dev. Furthermore, no 424 power management functions are exposed, as those are handled by the 425 general ACPI drivers. 426 427 More information about this driver is available at 428 <http://memebeam.org/toys/ToshibaAcpiDriver>. 429 430 If you have a legacy free Toshiba laptop (such as the Libretto L1 431 series), say Y. 432endif # X86_PLATFORM_DEVICES 433
