	5 - UltraBase battery slot

	6 - (unknown)

	7 - standby

	8 - dock status 1

	9 - dock status 2

All of the above can be turned on and off and can be made to blink.

The ThinkPad LED sysfs interface is described in detail by the LED class

documentation, in Documentation/leds-class.txt.

The leds are named (in LED ID order, from 0 to 7):

The LEDs are named (in LED ID order, from 0 to 12):

"tpacpi::power", "tpacpi:orange:batt", "tpacpi:green:batt",

"tpacpi::dock_active", "tpacpi::bay_active", "tpacpi::dock_batt",

"tpacpi::unknown_led", "tpacpi::standby".

"tpacpi::unknown_led", "tpacpi::standby", "tpacpi::dock_status1",

"tpacpi::dock_status2", "tpacpi::unknown_led2", "tpacpi::unknown_led3",

"tpacpi::thinkvantage".

Due to limitations in the sysfs LED class, if the status of the LED

indicators cannot be read due to an error, thinkpad-acpi will report it as

"timer" trigger, and leave the delay_on and delay_off parameters set to

zero (to request hardware acceleration autodetection).

LEDs that are known not to exist in a given ThinkPad model are not

made available through the sysfs interface.  If you have a dock and you

notice there are LEDs listed for your ThinkPad that do not exist (and

are not in the dock), or if you notice that there are missing LEDs,

a report to ibm-acpi-devel@lists.sourceforge.net is appreciated.

ACPI sounds -- /proc/acpi/ibm/beep

----------------------------------

display backlight brightness control methods have 16 levels, ranging

from 0 to 15.

There are two interfaces to the firmware for direct brightness control,

EC and UCMS (or CMOS).  To select which one should be used, use the

brightness_mode module parameter: brightness_mode=1 selects EC mode,

brightness_mode=2 selects UCMS mode, brightness_mode=3 selects EC

mode with NVRAM backing (so that brightness changes are remembered

across shutdown/reboot).

For IBM ThinkPads, there are two interfaces to the firmware for direct

brightness control, EC and UCMS (or CMOS).  To select which one should be

used, use the brightness_mode module parameter: brightness_mode=1 selects

EC mode, brightness_mode=2 selects UCMS mode, brightness_mode=3 selects EC

mode with NVRAM backing (so that brightness changes are remembered across

shutdown/reboot).

The driver tries to select which interface to use from a table of

defaults for each ThinkPad model.  If it makes a wrong choice, please

report this as a bug, so that we can fix it.

Lenovo ThinkPads only support brightness_mode=2 (UCMS).

When display backlight brightness controls are available through the

standard ACPI interface, it is best to use it instead of this direct

ThinkPad-specific interface.  The driver will disable its native

procfs: /proc/acpi/ibm/fan

sysfs device attributes: (hwmon "thinkpad") fan1_input, pwm1,

			  pwm1_enable

			  pwm1_enable, fan2_input

sysfs hwmon driver attributes: fan_watchdog

NOTE NOTE NOTE: fan control operations are disabled by default for

to work on later R, T, X and Z series ThinkPads but may show a bogus

value on other models.

Some Lenovo ThinkPads support a secondary fan.  This fan cannot be

controlled separately, it shares the main fan control.

Fan levels:

Most ThinkPad fans work in "levels" at the firmware interface.  Level 0

	which can take up to two minutes.  May return rubbish on older

	ThinkPads.

hwmon device attribute fan2_input:

	Fan tachometer reading, in RPM, for the secondary fan.

	Available only on some ThinkPads.  If the secondary fan is

	not installed, will always read 0.

hwmon driver attribute fan_watchdog:

	Fan safety watchdog timer interval, in seconds.  Minimum is

	1 second, maximum is 120 seconds.  0 disables the watchdog.

0x020300:	hotkey enable/disable support removed, attributes

		hotkey_bios_enabled and hotkey_enable deprecated and

		marked for removal.

0x020400:	Marker for 16 LEDs support.  Also, LEDs that are known

		to not exist in a given model are not registered with

		the LED sysfs class anymore.
