  286. the bay while buses are still active), etc.
  287. LED control on the ThinkPad is write-only (with very few
  288. exceptions on very ancient models), which makes it
  289. impossible to know beforehand if important information will
  290. be lost when one changes LED state.
  291. Users that know what they are doing can enable this option
  292. and the driver will allow control of every LED, including
  293. the ones on the dock stations.

  310. bad interactions with X.org.
  311. NOTE: access to this feature is limited to processes with the

  323. need to do NVRAM polling to support any of the hot keys you use,
  324. unselecting this option will save about 1kB of memory.

  414. This driver adds support for the ACPI-WMI (Windows Management
  415. Instrumentation) mapper device (PNP0C14) found on some systems.
  416. ACPI-WMI is a proprietary extension to ACPI to expose parts of the
  417. ACPI firmware to userspace - this is done through various vendor
  418. defined methods and data blocks in a PNP0C14 device, which are then
  419. made available for userspace to call.
  420. The implementation of this in Linux currently only exposes this to
  421. other kernel space drivers.
  422. This driver is a required dependency to build the firmware specific
  423. drivers needed on many machines, including Acer and HP laptops.

  445. /proc/acpi/events, and (on some models) adds support for changing the
  446. display brightness and output, switching the LCD backlight on and off,
  447. and most importantly, allows you to blink those fancy LEDs intended
  448. for reporting mail and wireless status.
  449. Note: display switching code is currently considered EXPERIMENTAL,
  450. toying with these values may even lock your machine.
  451. All settings are changed via /proc/acpi/asus directory entries. Owner
  452. and group for these entries can be set with asus_uid and asus_gid

  483. their lack of a BIOS setup menu and APM support.
  484. On these machines, all system configuration is handled through the
  485. ACPI. This driver is required for access to controls not covered
  486. by the general ACPI drivers, such as LCD brightness, video output,
  487. etc.
  488. This driver differs from the non-ACPI Toshiba laptop driver (located
  489. under "Processor type and features") in several aspects.
  490. Configuration is accessed by reading and writing text files in the
  491. /proc tree instead of by program interface to /dev. Furthermore, no
  492. power management functions are exposed, as those are handled by the
