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):
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.
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:
Experimental: CMOS control - /proc/acpi/ibm/cmos
------------------------------------------------
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.
Note: the UltraBay eject support on the 600e/x, A22p and A3x is
EXPERIMENTAL and may not work as expected. USE WITH CAUTION!

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

his laptop (the location of sensors may vary on other models):

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:

Another set of values that varies often is the temperature
readings. Since temperatures don't change vary fast, you can take
several quick dumps to eliminate them.
You can use a similar method to figure out the meaning of other
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:
echo 'level <level>' > /proc/acpi/ibm/thermal

"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.
