Problem with fan noise

2005-05-09T09:13:05Z

UW(e): Minor suggestion for example script.

Information about the fan noise problem in Thinkpad models from 2003/2004.

==Problem description==

There seem to be two different occurances of the problem (or two different problems).

===acceleration problem:===
The Thinkpad Fan accelerates in regular intervals, making an annoying noise.

===always on problem:===
The Fan is always on, even though the processor is rather cool.

==Affected Models==

===acceleration problem:===
*Thinkpad T40, T40p, T41, T42(?)

===always on problem:===
*Thinkpad T40, T40p, T41, T41p, T42, T42p, T43
*Thinkpad R50, R50p, R51, R52, R32
*Thinkpad X40
*Thinkpad A31p
*Thinkpad 770X

==Affected Operating Systems==

===acceleration problem:===
*Linux, all flavours

===always on problem:===
*Linux, all flavours
*FreeBSD 5.3
*Windows XP
*Windows 2000 pro

==Status==

===acceleration problem:===
IBM released an update to the embedded controller program that seems to at least partially solve this problem:

Version 3.03 - 1RHT70WW
NOTE: This version of Embedded Controller Program will only work with BIOS Version 3.06f (or higher).
* (Fix) Reduced Fan noise in some models.

The update can be found here: http://www-306.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-50279

===always on problem:===
The problem is yet unsolved. But see the partial fix below.

IBM made a statement regarding this on their homepage:
http://www-307.ibm.com/pc/support/site.wss/MIGR-56504.html

It seems that it's a feature of centrino - http://mailman.linux-thinkpad.org/pipermail/linux-thinkpad/2004-September/019737.html
Perhaps it's fixable by adding the fans and temps to the dsdt?

==Solutions==

===acceleration problem:===

====Replacing the fan====
Some people reported that they replaced the original fan against one of a similar notebook without the problem has worked for them,
i.e. changing a T41s fan against one from a T41p.

====BIOS upgrade====
You can try upgrading your embedded controller program to version 3.03 or newer.

The update can be found here: http://www-306.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-50279

===always on problem:===

It seems like for some people a combination of enabling dynamic frequency scaling and using the most recent radeon drivers (from xorg 6.8.x) with the DynamicClocks option enabled helped lowing the fan rotation and hence making it more quiet.

Also the fglrx driver from ATI is said to show the same effect when used together with dynamic frequency scaling.

On a 770X the fan can be fully controlled through ACPI. Thermal Zone THM5 (possibly the battery/charging circuit, it's definitely warmer when using 5v PCMCIA cards and AC) triggers it to turn on and not ever off by design. Can be solved by a custom DSDT, which also makes use of the variable-speed features of the fan (will release this once I've finished tweaking and testing it).

====partial fix:====
When loading [http://ibm-acpi.sourceforge.net/ IBM ThinkPad ACPI Extras v0.11] with experimental switch (modprobe ibm_acpi experimantal=1), it is possible to read and write the status of fan:

'''#cat /proc/acpi/ibm/fan'''
status: enabled
speed: 3580
commands: enable, disable

'''#echo disable > /proc/acpi/ibm/fan'''

'''cat /proc/acpi/ibm/fan'''
status: disabled
speed: 0
commands: enable, disable

But the fan will then '''never''' wake up. So, we need a small script witch is constantly checking the temperature and setting the fan on/off when needed. (deamon? cron job?) If anyone has an idea please post it here.

'''sh script example'''

<pre>
#!/bin/sh

MAXTEMP=50

while [ 1 ];
do
fan=no

for temp in `sed s/temperatures:// < /proc/acpi/ibm/thermal`
do
test $temp -gt $MAXTEMP && fan=yes
done

command='disable'
test "$fan" = "yes" && command='enable'
echo $command > /proc/acpi/ibm/fan

sleep 20
done
</pre>

'''sh script example with more features'''

<pre>

#!/bin/sh

# fan control-script
#
# based upon ibm-acpi 0.11 (experimental=1 !)
#
# eliminates anoying "fan always on" in battery mode
# works with hysteresis (DELTA) so that always-turn-on/turn-off is avoided
# fan acivates at MAXTEMP and cools down CPU, GPU etc. to MAXTEMP-DELTA than the fan is turned off
# furthermore detects if AC is on and gives back fan control to default behaviour than
#
# one can change MAXTEMP and DELTA to individual values
# but take care of your THINKPAD don`t melt it!
#
# have fun!
# mk 05.05.05

MAXTEMP=51
DELTA=4

SWITCHTEMP=$MAXTEMP

while [ 1 ];
do
for ac in `sed s/state:// < /proc/acpi/ac_adapter/AC/state`
do
if [ "$ac" = "off-line" ]; then
fan=no
for temp in `sed s/temperatures:// < /proc/acpi/ibm/thermal`
do
test $temp -gt $SWITCHTEMP && fan=yes
done

if [ "$fan" = "yes" ]; then
command='enable'
SWITCHTEMP=`expr $MAXTEMP - $DELTA`
else
SWITCHTEMP=$MAXTEMP
command='disable'
fi

else # ac-adapter on -> set fan control to standard behaviour
command='enable'
fi

echo $command > /proc/acpi/ibm/fan
sleep 15
done
done

</pre>

{{HINT| For a little bit additional security, I would suggest to add the following line. This *might* help to enable the fan, in case the script gets killed.}}
<pre>
trap "echo enable > /proc/acpi/ibm/fan" EXIT
</pre>
{{WARN|However, no guarantee from me about that. Be careful and use at your own risk!}}

'''daemon script example'''

<pre>
#! /bin/sh

N=/etc/init.d/fan

set -e

case "$1" in
start)
# make sure privileges don't persist across reboots
if [ -d /var/run/fan ] && [ "x`ls /var/run/fan`" != x ]
then
touch -t 198501010000 /var/run/fan/*
fi

echo "Usage: $N {start|stop|restart|force-reload}" >&2

'''If the ATI driver works only without the hardware acceleration''', take into consideration that fglrx_dri.so was linked
against libstdc++.so.5 which may not be present if your system uses gcc-3.4. To fix this, compile gcc-3.3.5
and copy libstdc++.so.5* to /usr/lib and update the dynamic linker cache.

'''Troubles using software suspend''' : when the computer comes back of suspend, X only displays a garbaged image and the computer is frozen. You have to install [http://www.srcf.ucam.org/~mjg59/vbetool/ vbetool] and use it to save/restore the video card state. If you use swsusp2 scripts you just have to uncomment ''"EnableVbetool yes"'' in ''/etc/hibernate/hibernate.conf''. Tested with kernel 2.6.10, Debian packaged ATI drivers and [http://www.suspend2.net swsusp2] patch on a IBM Thinkpad T42p.

==Lithium-based batteries==

*store them at about 40% charged state
*never store them fully depleted/charged
*keep them cool and dry, deeply frozen is best as long as it is dry
*the battery lasts longer with partial rather than full discharges
*avoid charging if the battery is nearly full

Problem with high power drain in ACPI sleep

2005-01-13T11:59:25Z

UW(e): /* Status */

Information about the problem of too high power drain in ACPI sleep mode.

==Problem description==
Several people realised that their ThinkPads eat up too much power while suspended to ram via ACPI. Compared to APM suspend to ram the power drain is experienced to be about 10 times as high, 2-5 Watts. This empties the battery within one or two days.

==Affected Models==
*Different symptoms have been reported for different models. In some models the origin of the power drain is obvious (backlight on during suspend), in other models there is no obvious reason.
*On some models/configurations the higher power drain couldn't even be realized or was at least significantly lower.
*The T4x thinkpad series (T40, T40p, T41, T41p, T42, T42p) suspends to ram just fine, and there are no components that are obviously left powered up. The ultrabay and network light is on, but that is the same under windows (but under APM sleep to RAM those lights are OFF).
The following table gives an overview of the models suffering from the mysterious power drain. To find out about your model, you may use the following [[ACPI sleep power drain test script | script]]. It creates a file <tt>/var/log/battery.log</tt> which will tell you if you are affected or not.

==Affected Operating Systems==

*Linux, all flavours.

==Status==
The cause of the problem is not really clear, yet.

A faulty DSDT might be responsible for the phenomena. The thinkpad T4x DSDT has a few small bugs, none of which should cause the extra power drain. (Interesting to note: The DSDT from BIOS 3.13 (Nov 04) for the T42p compiles without bugs.)

There is a interesting discussion taking place in the [http://bugme.osdl.org/show_bug.cgi?id=3022 OSDL Bugzilla].

None so far.

Modem Devices

UW(e): /* Internal Thinkpad Modem */

== Internal Thinkpad Modem ==

Linux drivers for the various internal Thinkpad modems.

=== scanModem script ===

To identify your internal modem, it is always a good advice to start with the scanModem script from:

http://linmodems.technion.ac.il/#scanmodem

Grab a current version and have a look at its output.

=== Agere (T40p) ===

Give the drivers for Agere Softmodems from Smartlink a try:

http://www.smlink.com/main/item.php?ln=en&item_id=84&main_id=32

=== Conexant (T42p) ===

Although, the Smartlink driver for Agere modems (see above) is able to communicate with the modem via AT commands, it cannot dial out (contradicting reports welcome!).

If your favourite distribution does not include a hsfmodem driver (search for "hsfmodem" or "Conexant"), you can try the one from Linuxant:

http://www.linuxant.com/drivers
