Some of the ThinkPad LEDs indicate critical conditions that can cause data loss or cause hardware damage when ignored (e.g. force-ejecting a powered up bay; ignoring a failing battery, or empty battery; force- undocking with the dock buses still active, etc). On almost all ThinkPads, LED access is write-only, and the firmware usually does fire-and-forget signaling on them, so you effectively lose whatever message the firmware was trying to convey to the user when you override the LED state, without any chance to restore it. Restrict access to all LEDs that can convey important alarms, or that could mislead the user into incorrectly operating the hardware. This will make the Lenovo engineers less unhappy about the whole issue. Allow users that really want it to still control all LEDs, it is the unaware user that we have to worry about.

LED control on the ThinkPad is write-only (with very few

the hot key press events. If you know your ThinkPad model does not

need to do NVRAM polling to support any of the hot keys you use,

ThinkPads T40 and newer, R52 and newer, and X31 and newer are

|
This driver adds support for the ACPI-WMI (Windows Management

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

It is safe to enable this driver even if your DSDT doesn't define

This driver provides support for extra features of ACPI-compatible

support some Medion laptops (such as 9675 for example). It makes all
|
|
the extra buttons generate standard ACPI events that go through
|
|
/proc/acpi/events, and (on some models) adds support for changing the
|
|
display brightness and output, switching the LCD backlight on and off,
|
|
and most importantly, allows you to blink those fancy LEDs intended
|
|
for reporting mail and wireless status.
|
|
|
|
Note: display switching code is currently considered EXPERIMENTAL,
|
|
toying with these values may even lock your machine.
|
|
|
|
All settings are changed via /proc/acpi/asus directory entries. Owner
|
|
and group for these entries can be set with asus_uid and asus_gid

parameters.

More information and a userspace daemon for handling the extra buttons

This driver adds support for access to certain system settings

their lack of a BIOS setup menu and APM support.

|
ACPI. This driver is required for access to controls not covered

by the general ACPI drivers, such as LCD brightness, video output,

|
etc.
|
|

This driver differs from the non-ACPI Toshiba laptop driver (located

|
under "Processor type and features") in several aspects.
|
|
Configuration is accessed by reading and writing text files in the
|
|
/proc tree instead of by program interface to /dev. Furthermore, no
|
|
power management functions are exposed, as those are handled by the
|
|
general ACPI drivers.
