+Docking / undocking -- /proc/acpi/ibm/dock
------------------------------------------
Docking and undocking (e.g. with the X4 UltraBase) requires some
when originally booted. This is due to the current lack of support for
hot plugging of devices in the Linux ACPI framework. If the laptop was
booted while not in the dock, the following message is shown in the
-logs: "ibm_acpi: dock device not present". No dock-related events are
-generated but the dock and undock commands described below still
-work. They can be executed manually or triggered by Fn key
-combinations (see the example acpid configuration files included in
-the driver tarball package available on the web site).

+manually or triggered by Fn key combinations (see the example acpid
+configuration files included in the driver tarball package available

When the eject request button on the dock is pressed, the first event
above is generated. The handler for this event should issue the
UltraBase docks and "dumb" port replicators like the Mini Dock (the
latter don't need any ACPI support, actually).
-UltraBay Eject -- /proc/acpi/ibm/bay
+UltraBay eject -- /proc/acpi/ibm/bay
------------------------------------
Inserting or ejecting an UltraBay device requires some actions to be

This is due to the current lack of support for hot plugging of devices
in the Linux ACPI framework. If the laptop was booted without the

The contents of the /proc/acpi/ibm/bay file shows the current status
of the UltraBay, as provided by the ACPI framework.
-Experimental Features
----------------------
+EXPERIMENTAL warm eject support on the 600e/x, A22p and A3x (To use
+this feature, you need to supply the experimental=1 parameter when
+loading the module):
+
+These models do not have a button near the UltraBay device to request
+a hot eject but rather require the laptop to be put to sleep
+(suspend-to-ram) before the bay device is ejected or inserted).
+The sequence of steps to eject the device is as follows:
+
+ echo eject > /proc/acpi/ibm/bay
+ put the ThinkPad to sleep
+ remove the drive
+ resume from sleep
+ cat /proc/acpi/ibm/bay should show that the drive was removed
+
+On the A3x, both the UltraBay 2000 and UltraBay Plus devices are
+supported. Use "eject2" instead of "eject" for the second bay.
-The following features are marked experimental because using them
-involves guessing the correct values of some parameters. Guessing
-incorrectly may have undesirable effects like crashing your
-ThinkPad. USE THESE WITH CAUTION! To activate them, you'll need to
-supply the experimental=1 parameter when loading the module.
+Note: the UltraBay eject support on the 600e/x, A22p and A3x is
+EXPERIMENTAL and may not work as expected. USE WITH CAUTION!
-Experimental: CMOS control - /proc/acpi/ibm/cmos
-------------------------------------------------
+CMOS control -- /proc/acpi/ibm/cmos
+-----------------------------------
This feature is used internally by the ACPI firmware to control the
-ThinkLight on most newer ThinkPad models. It appears that it can also
-control LCD brightness, sounds volume and more, but only on some
-models.
+ThinkLight on most newer ThinkPad models. It may also control LCD
+brightness, sounds volume and more, but only on some models.
The commands are non-negative integer numbers:
echo 2 >/proc/acpi/ibm/cmos
...
-The range of numbers which are used internally by various models is 0
-to 21, but it's possible that numbers outside this range have
-interesting behavior. Here is the behavior on the X40 (tpb is the
-ThinkPad Buttons utility):
+The range of valid numbers is 0 to 21, but not all have an effect and
+the behavior varies from model to model. Here is the behavior on the
+X40 (tpb is the ThinkPad Buttons utility):
0 - no effect but tpb reports "Volume down"
1 - no effect but tpb reports "Volume up"
13 - ThinkLight off
14 - no effect but tpb reports ThinkLight status change
-If you try this feature, please send me a report similar to the
-above. On models which allow control of LCD brightness or sound
-volume, I'd like to provide this functionality in an user-friendly
-way, but first I need a way to identify the models which this is
-possible.
-
-Experimental: LED control - /proc/acpi/ibm/LED
-----------------------------------------------
+LED control -- /proc/acpi/ibm/led
+---------------------------------
Some of the LED indicators can be controlled through this feature. The
available commands are:
- echo <led number> on >/proc/acpi/ibm/led
- echo <led number> off >/proc/acpi/ibm/led
- echo <led number> blink >/proc/acpi/ibm/led
+ echo '<led number> on' >/proc/acpi/ibm/led
+ echo '<led number> off' >/proc/acpi/ibm/led
+ echo '<led number> blink' >/proc/acpi/ibm/led
-The <led number> parameter is a non-negative integer. The range of LED
-numbers used internally by various models is 0 to 7 but it's possible
-that numbers outside this range are also valid. Here is the mapping on
-the X40:
+The <led number> range is 0 to 7. The set of LEDs that can be
+controlled varies from model to model. Here is the mapping on the X40:

1 - battery (orange)
All of the above can be turned on and off and can be made to blink.
-If you try this feature, please send me a report similar to the
-above. I'd like to provide this functionality in an user-friendly way,
-but first I need to identify the which numbers correspond to which
-LEDs on various models.

-Experimental: ACPI sounds - /proc/acpi/ibm/beep
------------------------------------------------
+ACPI sounds -- /proc/acpi/ibm/beep
+----------------------------------
The BEEP method is used internally by the ACPI firmware to provide
-audible alerts in various situtation. This feature allows the same
+audible alerts in various situations. This feature allows the same
sounds to be triggered manually.
The commands are non-negative integer numbers:
- echo 0 >/proc/acpi/ibm/beep
- echo 1 >/proc/acpi/ibm/beep
- echo 2 >/proc/acpi/ibm/beep
- ...
+ echo <number> >/proc/acpi/ibm/beep
-The range of numbers which are used internally by various models is 0
-to 17, but it's possible that numbers outside this range are also
-valid. Here is the behavior on the X40:
+The valid <number> range is 0 to 17. Not all numbers trigger sounds
+and the sounds vary from model to model. Here is the behavior on the
+X40:
- 2 - two beeps, pause, third beep
+ 0 - stop a sound in progress (but use 17 to stop 16)
+ 2 - two beeps, pause, third beep ("low battery")
3 - single beep
- 4 - "unable"
+ 4 - high, followed by low-pitched beep ("unable")
5 - single beep
- 6 - "AC/DC"
+ 6 - very high, followed by high-pitched beep ("AC/DC")
7 - high-pitched beep
9 - three short beeps
10 - very long beep
12 - low-pitched beep
+ 15 - three high-pitched beeps repeating constantly, stop with 0
+ 16 - one medium-pitched beep repeating constantly, stop with 17
+ 17 - stop 16
+
+Temperature sensors -- /proc/acpi/ibm/thermal
+---------------------------------------------
+
+Most ThinkPads include six or more separate temperature sensors but
+only expose the CPU temperature through the standard ACPI methods.
+This feature shows readings from up to eight different sensors. Some
+readings may not be valid, e.g. may show large negative values. For
+example, on the X40, a typical output may be:
+
+temperatures: 42 42 45 41 36 -128 33 -128
+
+Thomas Gruber took his R51 apart and traced all six active sensors in
+his laptop (the location of sensors may vary on other models):
+
+1: CPU
+2: Mini PCI Module
+3: HDD
+4: GPU
+5: Battery
+6: N/A
+7: Battery
+8: N/A
+
+No commands can be written to this file.
+
+EXPERIMENTAL: Embedded controller reigster dump -- /proc/acpi/ibm/ecdump
+------------------------------------------------------------------------
+
+This feature is marked EXPERIMENTAL because the implementation
+directly accesses hardware registers and may not work as expected. USE
+WITH CAUTION! To use this feature, you need to supply the
+experimental=1 parameter when loading the module.
+
+This feature dumps the values of 256 embedded controller
+registers. Values which have changed since the last time the registers
+were dumped are marked with a star:

+This feature can be used to determine the register holding the fan
+speed on some models. To do that, do the following:
+
+ - make sure the battery is fully charged
+ - make sure the fan is running
+ - run 'cat /proc/acpi/ibm/ecdump' several times, once per second or so
+
+The first step makes sure various charging-related values don't
+vary. The second ensures that the fan-related values do vary, since
+the fan speed fluctuates a bit. The third will (hopefully) mark the
+fan register with a star:

+embedded controller registers - e.g. make sure nothing else changes
+except the charging or discharging battery to determine which
+registers contain the current battery capacity, etc. If you experiment
+with this, do send me your results (including some complete dumps with
+a description of the conditions when they were taken.)
+
+EXPERIMENTAL: LCD brightness control -- /proc/acpi/ibm/brightness
+-----------------------------------------------------------------
+
+This feature is marked EXPERIMENTAL because the implementation
+directly accesses hardware registers and may not work as expected. USE
+WITH CAUTION! To use this feature, you need to supply the
+experimental=1 parameter when loading the module.
+
+This feature allows software control of the LCD brightness on ThinkPad
+models which don't have a hardware brightness slider. The available
+commands are:
+
+ echo up >/proc/acpi/ibm/brightness
+ echo down >/proc/acpi/ibm/brightness
+ echo 'level <level>' >/proc/acpi/ibm/brightness
+
+The <level> number range is 0 to 7, although not all of them may be
+distinct. The current brightness level is shown in the file.
+
+EXPERIMENTAL: Volume control -- /proc/acpi/ibm/volume
+-----------------------------------------------------
+
+This feature is marked EXPERIMENTAL because the implementation
+directly accesses hardware registers and may not work as expected. USE
+WITH CAUTION! To use this feature, you need to supply the
+experimental=1 parameter when loading the module.
+
+This feature allows volume control on ThinkPad models which don't have
+a hardware volume knob. The available commands are:
+
+ echo up >/proc/acpi/ibm/volume
+ echo down >/proc/acpi/ibm/volume
+ echo mute >/proc/acpi/ibm/volume
+ echo 'level <level>' >/proc/acpi/ibm/volume
+
+The <level> number range is 0 to 15 although not all of them may be
+distinct. The unmute the volume after the mute command, use either the
+up or down command (the level command will not unmute the volume).
+The current volume level and mute state is shown in the file.
+
+EXPERIMENTAL: fan speed, fan enable/disable -- /proc/acpi/ibm/fan
+-----------------------------------------------------------------
+
+This feature is marked EXPERIMENTAL because the implementation
+directly accesses hardware registers and may not work as expected. USE
+WITH CAUTION! To use this feature, you need to supply the
+experimental=1 parameter when loading the module.
+
+This feature attempts to show the current fan speed. The speed is read
+directly from the hardware registers of the embedded controller. This
+is known to work on later R, T and X series ThinkPads but may show a
+bogus value on other models.
+
+The fan may be enabled or disabled with the following commands:
+
+ echo enable >/proc/acpi/ibm/fan
+ echo disable >/proc/acpi/ibm/fan
+
+WARNING WARNING WARNING: do not leave the fan disabled unless you are
+monitoring the temperature sensor readings and you are ready to enable
+it if necessary to avoid overheating.
+
+The fan only runs if it's enabled *and* the various temperature
+sensors which control it read high enough. On the X40, this seems to
+depend on the CPU and HDD temperatures. Specifically, the fan is
+turned on when either the CPU temperature climbs to 56 degrees or the
+HDD temperature climbs to 46 degrees. The fan is turned off when the
+CPU temperature drops to 49 degrees and the HDD temperature drops to
+41 degrees. These thresholds cannot currently be controlled.
+
+On the X31 and X40 (and ONLY on those models), the fan speed can be
+controlled to a certain degree. Once the fan is running, it can be
+forced to run faster or slower with the following command:
+
+ echo 'speed <speed>' > /proc/acpi/ibm/thermal
+
+The sustainable range of fan speeds on the X40 appears to be from
+about 3700 to about 7350. Values outside this range either do not have
+any effect or the fan speed eventually settles somewhere in that
+range. The fan cannot be stopped or started with this command.
+
+On the 570, temperature readings are not available through this
+feature and the fan control works a little differently. The fan speed
+is reported in levels from 0 (off) to 7 (max) and can be controlled
+with the following command:
-(I've only been able to identify a couple of them).

-If you try this feature, please send me a report similar to the
-above. I'd like to provide this functionality in an user-friendly way,
-but first I need to identify the which numbers correspond to which
-sounds on various models.

- "Power Management" means that parts of your computer are shut
- off or put into a power conserving "sleep" mode if they are not
- being used. There are two competing standards for doing this: APM
- and ACPI. If you want to use either one, say Y here and then also
- to the requisite support below.
-
- Power Management is most important for battery powered laptop
- computers; if you have a laptop, check out the Linux Laptop home
- page on the WWW at <http://www.linux-on-laptops.com/> and the
- Battery Powered Linux mini-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>.
-
- Note that, even if you say N here, Linux on the x86 architecture
- will issue the hlt instruction if nothing is to be done, thereby
- sending the processor to sleep and saving power.
