  294. firmware alerts (like critical battery condition), or misled
  295. the user into damaging the hardware (undocking or ejecting
  296. the bay while buses are still active), etc.
  297. LED control on the ThinkPad is write-only (with very few
  298. exceptions on very ancient models), which makes it
  299. impossible to know beforehand if important information will
  300. be lost when one changes LED state.
  301. Users that know what they are doing can enable this option
  302. and the driver will allow control of every LED, including
  303. the ones on the dock stations.
  304. Never enable this option on a distribution kernel.

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

  428. ACPI-WMI is a proprietary extension to ACPI to expose parts of the

  430. defined methods and data blocks in a PNP0C14 device, which are then
  431. made available for userspace to call.

  460. for reporting mail and wireless status.
  461. Note: display switching code is currently considered EXPERIMENTAL,
