The tp_smapi kernel module exposes some features of the ThinkPad hardware/firmware via a sysfs interface. Currently, the main implemented functionality is control of battery charging and extended battery status. The tp_smapi software package also includes an improved version of the HDAPS driver. The underlying hardware interfaces are SMAPI and direct access to the embedded controller.

This driver uses undocumented features and direct hardware access, so it may work unreliably or even damage your hardware; but so far no such damage has been reported.

If you are installing on a recent Thinkpad that has an Ivy Bridge or newer processor (X230, T430, T530, etc.), tp_smapi will not work. You will be mostly limited to thinkpad-acpi capabilities. You can however set battery charge thresholds with tpacpi-bat.

Features

tp_smapi driver
- Battery charge/discharge control
- Battery status information
hdaps driver (compared with the standard hdaps driver)
- Improved stability
- Improved model support
- Improved functionality

Project Homepage / Availability

Project page: http://tpctl.sourceforge.net/
Download page: http://sourceforge.net/projects/tpctl/files/tp_smapi, a newer version 0.41 is available in a fork at https://github.com/evgeni/tp_smapi which is also available in Debian
You need to download only the tp_smapi package.

Installation

Installation from source

You will need the kernel headers and makefiles corresponding to your current kernel version. On Fedora, this means # yum install kernel-devel-$(uname -r) .

# tar xzvf tp_smapi-0.40.tgz

# cd tp_smapi-0.40

Then, either compile and load the driver within the current working directory (for testing):

# make load

OR compile and install into the kernel's module path:

# make install

If you use the HDAPS driver, add HDAPS=1 to also patch the hdaps for compatibility with tp_smapi (this requires a kernel source tree matching the current kernel). Again, either load the driver within the current working directory:

# make load HDAPS=1

OR install into the kernel's module path:

# make install HDAPS=1

To prepare a stand-alone patch against the current kernel tree (including a patch against hdaps and new Kconfig entries):

# make patch

To delete all autogenerated files:

# make clean

The original kernel tree is never modified by any these commands. The /lib/modules directory is modified only by # make install.

Installation in Gentoo

The Gentoo portage system carries a tp_smapi package, which follows the latest version pretty closely. On a Gentoo system, you can install and load as follows.

If you use the HDAPS driver, do this first:

Disable the hdaps module in your kernel configuration (Device Drivers → Hardware Monitoring Support → IBM Hard Drive Active Protection System)
Rebuild and install the kernel
Add the hdaps use flag in /etc/make.conf
# rmmod hdaps

Then:

# emerge tp_smapi (or install tp_smapi with hdaps support manually, as above)
# echo "tp_smapi" >> /etc/modules.autoload.d/kernel-2.6
# echo "hdaps" >> /etc/modules.autoload.d/kernel-2.6

Then reboot, or run:

# modprobe tp_smapi
# modprobe hdaps

NOTE: If # modprobe fails and dmesg says something about __stack_chk_fail(), you probably just compiled your modules with -fstack-protector and/or -fstack-protector-all without having a kernel that supports it. You can either configure your kernel to have CC_STACKPROTECTOR enabled (in Processor type and features if you use # make menuconfig) or edit your make.conf (or, if you're using paludis, your /etc/paludis/bashrc) and remove -fstack-protector and -fstack-protector-all from your CFLAGS. If you choose to enable it in the kernel, be aware that you need a patched GCC for it (and I do not know if the gcc in stage3 is patched).

Installation on Debian and Ubuntu

Since Debian 7 Wheezy and Ubuntu 12.04 Precise you can use 'dkms'. (Note: If installation seems ineffective, confirm you have the linux-headers of your kernel installed, purge tp-smapi-dkms and reinstall.)

# apt-get install linux-headers tp-smapi-dkms
# modprobe tp_smapi

Hint:

This appears to be the ideal solution. A description of DKMS, from Dell: "DKMS stands for Dynamic Kernel Module Support. It is designed to create a framework where kernel dependent module source can reside so that it is very easy to rebuild modules as you upgrade kernels."

Installation on openSUSE

openSUSE provides rpm packages. Look for them at the package search: [1], search for the package named "tp_smapi".

A step-by-step guide on how a relative linux newbie installed tp_smapi on a Thinkpad W500 running openSuse 11.1 using YAST Software Manager is available here

In case you are taking the hard way around, while compiling on 11.0, make complained about not being able to locate the kernel sources. It worked for me after I did this:

cp /usr/include/linux/aio_abi.h /lib/modules/`uname -r`/build/include/linux/

Battery charge control features

NOTE!

Not all Thinkpad ECs support these charge control features. If you get the message "Operation not supported" when trying to cat for the status of a given parameter, it means your controller does not support that feature.

To set the thresholds for starting and stopping battery charging (in percent of current full charge capacity):

# echo 40 > /sys/devices/platform/smapi/BAT0/start_charge_thresh

# echo 70 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh

# cat /sys/devices/platform/smapi/BAT0/*_charge_thresh

Hint:

Battery charging thresholds can be used to keep Li-Ion and Li-Polymer batteries partially charged, in order to increase their lifetime.

To prevent charging for 17 minutes (regardless of thresholds):

# echo 17 > /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes

Hint:

Charge inhibiting can be used to reduce the power draw of the laptop, in order to use an under-spec power supply that can't handle the combined power draw of running and charging. It can also be used to control which battery is charged when using an Ultrabay battery.

To cancel charging preventation:

# echo 0 > /sys/devices/platform/smapi/BAT0/inhibit_charge_minutes

To force battery discharging (even if connected to AC):

# echo 1 > /sys/devices/platform/smapi/BAT0/force_discharge

Hint:

This can be used to choose which battery is discharged when using an UltraBay battery. For example, see the tp-bat-balance (download) script.

To cancel forced discharge:

# echo 0 > /sys/devices/platform/smapi/BAT0/force_discharge

Hint:

TPBattStat-Applet is a gnome applet for integrating battery balancing with a graphics and/or text display of both batteries in a panel. Battery balancing improves battery life by not leaving one battery empty while the other discharges. For the latest alpha release, see https://github.com/teleshoes/tpbattstat-applet

Making the settings permanent on reboot

If you always use the same type of battery, then you may want the same settings to be configured each time you boot the machine.

If you use various types of battery, then you may want to consider writing some scripts to detect the battery type and apply the appropriate settings.

Debian

It is not necessary to create your own init.d script or modify /etc/rc.local - you just need the package sysfsutils:

# apt-get install sysfsutils

Now, put your desired settings in /etc/sysfs.conf:

# cat >> /etc/sysfs.conf << EOF
# For a LiIon battery in a Thinkpad
devices/platform/smapi/BAT0/start_charge_thresh = 50
devices/platform/smapi/BAT0/stop_charge_thresh = 80
EOF

The init script supplied by sysfsutils will load these settings on each boot.

Battery status features

To view extended battery status such as charging state, voltage, current, capacity, cycle count and model information:

# cat /sys/devices/platform/smapi/BAT0/installed
# cat /sys/devices/platform/smapi/BAT0/state       # idle/charging/discharging
# cat /sys/devices/platform/smapi/BAT0/cycle_count
# cat /sys/devices/platform/smapi/BAT0/current_now # instantaneous current
# cat /sys/devices/platform/smapi/BAT0/current_avg # last minute average
# cat /sys/devices/platform/smapi/BAT0/power_now   # instantaneous power
# cat /sys/devices/platform/smapi/BAT0/power_avg   # last minute average
# cat /sys/devices/platform/smapi/BAT0/last_full_capacity
# cat /sys/devices/platform/smapi/BAT0/remaining_percent
# cat /sys/devices/platform/smapi/BAT0/remaining_running_time
# cat /sys/devices/platform/smapi/BAT0/remaining_charging_time
# cat /sys/devices/platform/smapi/BAT0/remaining_capacity
# cat /sys/devices/platform/smapi/BAT0/design_capacity
# cat /sys/devices/platform/smapi/BAT0/voltage
# cat /sys/devices/platform/smapi/BAT0/design_voltage
# cat /sys/devices/platform/smapi/BAT0/manufacturer
# cat /sys/devices/platform/smapi/BAT0/model
# cat /sys/devices/platform/smapi/BAT0/barcoding
# cat /sys/devices/platform/smapi/BAT0/chemistry
# cat /sys/devices/platform/smapi/BAT0/serial
# cat /sys/devices/platform/smapi/BAT0/manufacture_date
# cat /sys/devices/platform/smapi/BAT0/first_use_date
# cat /sys/devices/platform/smapi/BAT0/temperature # in milli-Celsius
# cat /sys/devices/platform/smapi/ac_connected

The raw status data is also available, including some fields not listed above (in case you can figure them out):

# cat /sys/devices/platform/smapi/BAT0/dump

In all of the above, replace BAT0 with BAT1 to address the 2nd battery.

Note that the battery status readout conflicts with the stock hdaps driver, so if you use hdaps you will need to load tp_smapi using # make load HDAPS=1 (see Bundled hdaps driver below).

On ACPI-enabled systems, most of above information is also available through the files under /proc/acpi/battery. However, the ACPI interface does not include the instantaneous power and cycle count readouts, and does not work well when hotswapping UltraBay batteries.

Scripts

Some scripts can make it easier to grep the information you need from tp_smapi

battery.rb

Other features

There is also sysfs attribute for making direct SMAPI requests to the SM BIOS firmware. Don't touch it unless you really know what you're doing. Example:

# echo '211a 100 0 0' > /sys/devices/platform/smapi/smapi_request; cat /sys/devices/platform/smapi/smapi_request
211a 34b b2 0 0 0 'OK'

The "4b" in the 2nd value, converted to decimal, is 75: the current charging stop threshold (stop_charge_thresh).

Bundled `hdaps` driver

The tp_smapi package includes a modified version of the hdaps Linux kernel driver used by the HDAPS system. It has remained outside the mainline kernel for a few years for several reasons, [2] including the upstream maintainer's assertion that the new code's anonymous author was under a NDA. (Although this would not normally expose the kernel team to litigation.) [3] [4] [5]

To use tp_smapi and hdaps concurrently, you must use the modified version.

To build the modified version, simply append the HDAPS=1 parameter to the make command (see Installation above):

# make load HDAPS=1

or

# make install HDAPS=1

If you don't do that, you will not be able to load tp_smapi (and its support module thinkpad_ec) when hdaps is loaded, and vice versa. You can use rmmod to switch between these modules.

Note that some of the battery status is also visible through ACPI (/proc/acpi/battery/*), independently of tp_smapi.

The modified hdaps has several changes:

The hdaps driver in mainline kernels conflicts with the extended battery status (they use the same IO ports). The modified hdaps coordinates this access through the bundled thinkpad_ec driver.
The modified hdaps driver fixes reliability and improves support for recent ThinkPad models (*60 and newer), since unlike the mainline driver, it correctly follows the Embedded Controller communication protocol.
Several other improvements, such as the ability to control the polling rate.

Troubleshooting

`thinkpad_ec: cannot claim io ports 0x1600-0x161f`

The "thinkpad_ec: cannot claim io ports 0x1600-0x161f!" error message is printed when loading the thinkpad_ec module on some recent ThinkPad models. This occurs because the ACPI BIOS DSDT is reserving ports used by tp_smapi.

As a workaround, add the force_io=1 module parameter to thinkpad_ec in /etc/modprobe.conf (or your distribution's equivalent). Add the line:

options thinkpad_ec force_io=1

For transient testing, load the modules as follows:

# make load HDAPS=1 FORCE_IO=1

Note: force_io option was added in tp_smapi v0.40 (released 2008-12-16).

Models which need this option include: T400, T500, X60s, X61, X301

More information:

`thinkpad_ec: no ThinkPad embedded controller!`

If you get "thinkpad_ec: no ThinkPad embedded controller!" when trying to load the module on a supported model listed below, you should upgrade your BIOS. Some early BIOS (like 1.x on the X31) don't handle the embedded controller.

`T60p writing to start_charge_thresh/stop_charge_thresh does not work!`

Writing to /sys/devices/platform/smapi/BAT0/start_charge_thresh succeeds, but the older value does not change. Solution: unknown. If you know a solution please update here.

UPDATE: Failure to effectively change sysfs values sometimes happens at boot time (through sysfs.conf OR etc/local.start for instance) when the values have never previously been changed manually (ie using echo from a shell). Try initializing the values manually before including them in boot-time scripting.

Model-specific status

Tip: The thinkpad-acpi module reports both the BIOS and EC firmware versions when it loads.

SL series and IdeaPad
The ThinkPad SL series and IdeaPad series have firmware that is completely different from other ThinkPad models. Neither tp_smapi nor thinkpad-acpi support these models.

SMAPI capabilities may depend on the BIOS version as well, so upgrading to the latest version of the BIOS might provide more SMAPI functions (especially true for long-lived BIOS with lots of releases, like the TP-1R).

Please update the above and report your experience on the discussion page. If the module loads but gives a "not supported" or "not implementeded" error when you try to use some specific file in /sys/devices/platform/smapi/, please report the dmesg output and whether the corresponding functionality is available under Windows - maybe your ThinkPad just can't do that.

While at it, you may also want to add your laptop to the list of DMI IDs.

HDAPS axis orientation

¹ The HDAPS axis orientation is set using the invert module parameter (at load time) or sysfs attribute (at runtime). The hdaps driver of tp_smapi supports all 8 possible sensor orientations (inversion and swapping). You can use hdaps visualisation to check if the settings is correct.

The invert parameter is an integer between 0 and 7, whose meaning is defined below. (This is confusing. Most people will find it easier to just try all 8 possibilities.)

Let X and Y denote the hardware readouts. Let R denote the laptop's roll (tilt left/right), and let P denote the laptop's pitch (tilt forward/backward). The possible values are as follows:

   invert=0:   R= X  P= Y   (same as mainline)
   invert=1:   R=-X  P=-Y   (same as mainline)
   invert=2:   R=-X  P= Y   (new)
   invert=3:   R= X  P=-Y   (new)
   invert=4:   R= Y  P= X   (new)
   invert=5:   R=-Y  P=-X   (new)
   invert=6:   R=-Y  P= X   (new)
   invert=7:   R= Y  P=-X   (new)

Tools using this driver

The driver's interface can be accessed directly through the files under /sys/devices/platform/smapi, or via the following tools:

KThinkBat - display battery status on the KDE kicker panel.
gkrellm-ThinkBat - battery status plugin for Gkrellm2
thinkpad-smapi.sh (download) - script to display various SMAPI information using tp_smapi module.

+This driver uses undocumented features and direct hardware access, so it may work unreliably or even damage your hardware; but so far no such damage has been reported.
-{{WARN|This driver uses undocumented features and direct hardware access. They thus cannot be guaranteed to work, and may cause arbitrary damage (though so far none was reported)..}}
+If you are installing on a recent Thinkpad that has an [[Ivy Bridge]] or newer processor ({{X230}}, {{T430}}, {{T530}}, etc.), tp_smapi will not work. You will be mostly limited to [[thinkpad-acpi]] capabilities. You can however set battery charge thresholds with [[tpacpi-bat]].

-:{{cmdroot|cd tp_smapi-0.17}}
+:{{cmdroot|tar xzvf tp_smapi-0.40.tgz}}
+:{{cmdroot|cd tp_smapi-0.40}}
+Then, either compile and load the driver within the current working directory (for testing):
 :{{cmdroot|make load}}
+OR compile and install into the kernel's module path:

 The original kernel tree is never modified by any these commands.
 The {{path|/lib/modules}} directory is modified only by {{cmdroot|make install}}.
+====Installation in Gentoo====
+The {{Gentoo}} portage system carries a [http://packages.gentoo.org/package/app-laptop/tp_smapi tp_smapi package], which follows the latest version pretty closely. On a Gentoo system, you can install and load as follows.
+If you use the [[HDAPS]] driver, do this first:
+* Disable the <tt>hdaps</tt> module in your kernel configuration (Device Drivers &rarr; Hardware Monitoring Support &rarr; IBM Hard Drive Active Protection System)
+* Rebuild and install the kernel
+* Add the <tt>hdaps</tt> use flag in {{path|/etc/make.conf}}
+* {{cmdroot|rmmod hdaps}}
+Then:
+* {{cmdroot|emerge tp_smapi}} (or install tp_smapi with hdaps support manually, as above)
+* {{cmdroot|echo "tp_smapi" >> /etc/modules.autoload.d/kernel-2.6}}
+* {{cmdroot|echo "hdaps" >> /etc/modules.autoload.d/kernel-2.6}}
+Then reboot, or run:
+* {{cmdroot|modprobe tp_smapi}}
+* {{cmdroot|modprobe hdaps}}
+'''NOTE:''' If {{cmdroot|modprobe}} fails and dmesg says something about <tt>__stack_chk_fail()</tt>, you probably just compiled your modules with <tt>-fstack-protector</tt> and/or <tt>-fstack-protector-all</tt> without having a kernel that supports it. You can either configure your kernel to have <tt>CC_STACKPROTECTOR</tt> enabled (in ''Processor type and features'' if you use {{cmdroot|make menuconfig}}) or edit your <tt>make.conf</tt> (or, if you're using paludis, your <tt>/etc/paludis/bashrc</tt>) and remove <tt>-fstack-protector</tt> and <tt>-fstack-protector-all</tt> from your <tt>CFLAGS</tt>. If you choose to enable it in the kernel, be aware that you need a patched GCC for it (and I do not know if the gcc in stage3 is patched).
+====Installation on Debian and Ubuntu====
+Since Debian 7 Wheezy and Ubuntu 12.04 Precise you can use 'dkms'. (Note: If installation seems ineffective, confirm you have the linux-headers of your kernel installed, purge tp-smapi-dkms and reinstall.)
+* {{cmdroot|apt-get install linux-headers tp-smapi-dkms}}
+* {{cmdroot|modprobe tp_smapi}}
+{{HINT|This appears to be the ideal solution. A description of DKMS, from [http://linux.dell.com/projects.shtml#dkms Dell]: "DKMS stands for Dynamic Kernel Module Support. It is designed to create a framework where kernel dependent module source can reside so that it is very easy to rebuild modules as you upgrade kernels."}}
+====Installation on openSUSE====
+openSUSE provides rpm packages. Look for them at the package search: [http://software.opensuse.org/search/], search for the package named "tp_smapi".
+A step-by-step guide on how a relative linux newbie installed tp_smapi on a Thinkpad W500 running openSuse 11.1 using YAST Software Manager is available [http://forums.opensuse.org/hardware/laptop/417254-tp_smapi-lenovo-thinkpad-t400-t500-w500-step-step.html#post2005932 here]
+In case you are taking the hard way around, while compiling on 11.0, make complained about not being able to locate the kernel sources. It worked for me after I did this:
+<pre><nowiki>cp /usr/include/linux/aio_abi.h /lib/modules/`uname -r`/build/include/linux/</nowiki></pre>
 ===Battery charge control features===
+{{NOTE|Not all Thinkpad ECs support these charge control features. If you get the message "Operation not supported" when trying to cat for the status of a given parameter, it means your controller does not support that feature.}}

 :{{cmdroot|cat /sys/devices/platform/smapi/BAT0/*_charge_thresh}}

+====Making the settings permanent on reboot====
+If you always use the same type of battery, then you may want the same settings to be configured each time you boot the machine.
+If you use various types of battery, then you may want to consider writing some scripts to detect the battery type and apply the appropriate settings.
+=====Debian=====
+It is not necessary to create your own init.d script or modify /etc/rc.local - you just need the package sysfsutils:
+:{{cmdroot|apt-get install sysfsutils}}
+Now, put your desired settings in /etc/sysfs.conf:
+<pre><nowiki># cat >> /etc/sysfs.conf << EOF
+# For a LiIon battery in a Thinkpad
+devices/platform/smapi/BAT0/start_charge_thresh = 50
+devices/platform/smapi/BAT0/stop_charge_thresh = 80
+EOF</nowiki></pre>
+The init script supplied by sysfsutils will load these settings on each boot.

+The "4b" in the 2nd value, converted to decimal, is 75: the current charging stop threshold (stop_charge_thresh).
+===Bundled <tt>hdaps</tt> driver===
+The tp_smapi package includes a modified version of the <tt>hdaps</tt> Linux kernel driver used by the [[HDAPS]] system. It has remained outside the mainline kernel for a few years for several reasons, [https://lists.ubuntu.com/archives/kernel-team/2009-April/005565.html] including the upstream maintainer's assertion that the new code's anonymous author was under a NDA. (Although this would not normally expose the kernel team to litigation.) [http://lkml.org/lkml/2008/9/15/126] [http://lkml.org/lkml/2008/10/7/403] [http://lkml.org/lkml/2008/10/7/428]
+To use <tt>tp_smapi</tt> and <tt>hdaps</tt> concurrently, you '''must''' use the modified version.
+To build the modified version, simply append the <tt>HDAPS=1</tt> parameter to the <tt>make</tt> command (see [[#Installation|Installation]] above):
+:{{cmdroot|1=make load HDAPS=1}}
+or
+:{{cmdroot|1=make install HDAPS=1}}
+If you don't do that, you will not be able to load <tt>tp_smapi</tt> (and its support module <tt>thinkpad_ec</tt>) when <tt>hdaps</tt> is loaded, and vice versa. You can use <tt>rmmod</tt> to switch between these modules.
+Note that some of the battery status is also visible through ACPI ({{path|/proc/acpi/battery/*}}), independently of <tt>tp_smapi</tt>.
+The modified <tt>hdaps</tt> has several changes:
+* The <tt>hdaps</tt> driver in mainline kernels conflicts with the extended battery status (they use the same IO ports). The modified <tt>hdaps</tt> coordinates this access through the bundled <tt>thinkpad_ec</tt> driver.
+* The modified <tt>hdaps</tt> driver fixes reliability and improves support for recent ThinkPad models (*60 and newer), since unlike the mainline driver, it correctly follows the Embedded Controller communication protocol.
+* Several other improvements, such as the ability to control the polling rate.
+===Troubleshooting===
+==== <tt>thinkpad_ec: cannot claim io ports 0x1600-0x161f</tt> ====
+The "<tt>thinkpad_ec: cannot claim io ports 0x1600-0x161f!</tt>" error message is printed when loading the <tt>thinkpad_ec</tt> module on some recent ThinkPad models.  This occurs because the ACPI BIOS DSDT is reserving ports used by tp_smapi.
-To control the speed of the optical drive:
+As a workaround, add the <tt>force_io=1</tt> module parameter to <tt>thinkpad_ec</tt> in {{path|/etc/modprobe.conf}} (or your distribution's equivalent). Add the line:
-:{{cmdroot|echo 0 > /sys/devices/platform/smapi/cd_speed # slow}}
+: options thinkpad_ec force_io=1
-:{{cmdroot|echo 1 > /sys/devices/platform/smapi/cd_speed # medium}}
-:{{cmdroot|echo 2 > /sys/devices/platform/smapi/cd_speed # fast}}
-:{{cmdroot|cat /sys/devices/platform/smapi/cd_speed}}
-=====Enabling this feature=====
+For transient testing, load the modules as follows:
-Changing the drive speed when a disc is being accessed will hang your computer. This feature is thus '''disabled by default''', but can be enabled using by adding <tt>#define PROVIDE_CD_SPEED</tt> at the top of <tt>tp_smapi.c</tt>. The safe way to set the drive speed is using <tt>hdparm -E num</tt> or <tt>eject -x num</tt> for CD-ROM, and <tt>speedcontrol -x num</tt> (sourcecode [http://safari.iki.fi/speedcontrol.c here]) for DVD. For kernels older than 2.6.15, this may require the [[Problems_with_SATA_and_Linux#No_SMART_support libata pass-through|libata pass-through patch]].
-===Features not yet implemented===
+: {{cmdroot|1=make load HDAPS=1 FORCE_IO=1}}
-Other things that can be controlled through SMAPI, but are not supported in this version of the driver, include PCI bus power saving, CPU power saving control and fan control (the latter is available through an [[How to control fan speed|alternative method]]). See the included README file for more information.
-===Conflict with <tt>hdaps</tt>===
+Note: force_io option was added in tp_smapi v0.40 (released 2008-12-16).
-The extended battery status function conflicts with the [[HDAPS|hdaps]] kernel module (they use the same IO ports).
-The <tt>tp_smapi</tt> package includes a patch against <tt>hdaps</tt> to make it compatible with <tt>tp_smapi</tt>. To build the patched version, append the <tt>HDAPS=1</tt> parameter to the <tt>make</tt> command, for example: {{cmdroot|1=make load HDAPS=1}} (see [[#Installation|Installation]] above).
+Models which need this option include: {{T400}}, {{T500}}, {{X60s}}, {{X61}}, {{X301}}
-If you don't do that:
+More information:
+* http://bugzilla.kernel.org/show_bug.cgi?id=12221
+* http://www.nabble.com/thinkpad_ec-fails-to-load-on-Thinkpad-T500-td19932985.html
-If you load <tt>hdaps</tt> first, <tt>tp_smapi</tt> will disable its battery status functions (and log a message in the kernel log). If you load <tt>tp_smapi</tt> first, <tt>hdaps</tt> will refuse to load. To switch between the two, <tt>rmmod</tt> both and then load one you need.
+==== <tt>thinkpad_ec: no ThinkPad embedded controller!</tt> ====
+If you get "<tt>thinkpad_ec: no ThinkPad embedded controller!</tt>" when trying to load the module on a supported model listed below, you should [[BIOS_Upgrade|upgrade your BIOS]]. Some early BIOS (like 1.x on the X31) don't handle the embedded controller.
-Some of the battery status is also visible through ACPI ({{path|/proc/acpi/battery/*}}).
+==== <tt>T60p writing to start_charge_thresh/stop_charge_thresh does not work!</tt> ====
+Writing to /sys/devices/platform/smapi/BAT0/start_charge_thresh succeeds, but the older value does not change. Solution: unknown. If you know a solution please update here.
-The charging control files (<tt>*_charge_thresh</tt>, <tt>inhibit_charge_minutes</tt> and <tt>force_discharge*</tt>) don't have this problem.
+UPDATE:  Failure to effectively change sysfs values sometimes happens at boot time (through sysfs.conf OR etc/local.start for instance) when the values have never previously been changed manually (ie using echo from a shell).  Try initializing the values manually before including them in boot-time scripting.
 ===Model-specific status===
+Tip: The <tt>thinkpad-acpi</tt> module reports both the BIOS and EC firmware versions when it loads.

-Please update the above and report your experience on the [[Talk:tp_smapi|discussion]] page. If the module loads but gives a "<tt>not supported</tt>" or "<tt>not implementeded</tt>" when you try to use some specific file in {{path|/sys/devices/platform/smapi/}}, please report the <tt>dmesg</tt> output and whether the corresponding functionality is available under Windows - maybe your ThinkPad just can't do that.
+SMAPI capabilities may depend on the BIOS version as well, so upgrading to the latest version of the BIOS might provide more SMAPI functions (especially true for long-lived BIOS with lots of releases, like the TP-1R).
+Please update the above and report your experience on the [[Talk:tp_smapi|discussion]] page. If the module loads but gives a "<tt>not supported</tt>" or "<tt>not implementeded</tt>" error when you try to use some specific file in {{path|/sys/devices/platform/smapi/}}, please report the <tt>dmesg</tt> output and whether the corresponding functionality is available under Windows - maybe your ThinkPad just can't do that.
+While at it, you may also want to add your laptop to the [[list of DMI IDs]].
+=====HDAPS axis orientation=====
+<sup>1</sup> The HDAPS axis orientation is set using the <tt>invert</tt> module parameter (at load time) or sysfs attribute (at runtime). The <tt>hdaps</tt> driver of tp_smapi supports all 8 possible sensor orientations (inversion and swapping). You can use [[HDAPS#Visualisation_of_ThinkPad_orientation|hdaps visualisation]] to check if the settings is correct.
+The <tt>invert</tt> parameter is an integer between 0 and 7, whose meaning is defined below. (This is confusing. Most people will find it easier to just try all 8 possibilities.)
+Let <tt>X</tt> and <tt>Y</tt> denote the hardware readouts. Let <tt>R</tt> denote the laptop's roll (tilt left/right), and let <tt>P</tt> denote the laptop's pitch (tilt forward/backward). The possible values are as follows:
+    invert=0:   R= X  P= Y   (same as mainline)
+    invert=1:   R=-X  P=-Y   (same as mainline)
+    invert=2:   R=-X  P= Y   (new)
+    invert=3:   R= X  P=-Y   (new)
+    invert=4:   R= Y  P= X   (new)
+    invert=5:   R=-Y  P=-X   (new)
+    invert=6:   R=-Y  P= X   (new)
+    invert=7:   R= Y  P=-X   (new)
