H8s: /* Troubles encountered */

This page is a provisorium. It's a list of things that are going wrong after the update to help [[User:akw|Akw]] track and fix them.

== Troubles encountered ==

'''Problem with cmdroot'''

Following String is not handled correct by template cmdroot:
"fakeroot make-kpkg --initrd --revision=thinkpad.1.0 kernel_image"

see here:
{{cmdroot|fakeroot make-kpkg --initrd --revision=thinkpad.1.0 kernel_image}}

'''Can not open page to edit without introducing modifications'''

If I open the [[X31]] model page and without touching anything I hit preview, the div token is decomposed and appears in the preview page, and of course, the photo is not in the right place.

Is there a way to contact a registered user, for example to confirm information. I have found that AdamZ claims that the X20 is bootable via USB. My information indicates the contrary. Isn't there a way to contact a registered user through MediaWiki? --[[User:Rolf|Rolf]] 00:30, 9 September 2006 (CEST)

You can't (easliy do a multiline {{cmdresult|cmdresult}}, can you? See:

{{cmdresult|foo
bar
baz}}

or

{{cmdresult|foo
bar (after whitespace)
baz (after whitespace)}}

This works (but is not so nice)

{{cmdresult|foo

bar (after empty line)

baz (after empty line)}}

Any suggestions?

[[User:Pebolle|Paul Bolle]] 10:27, 24 January 2006 (CET)

I think the best way is to use single cmdresult calls for each line and prefix them with a colon. Like so:
<pre><nowiki>
:{{cmdresult|foo}}
:{{cmdresult|bar}}
:{{cmdresult|baz}}
</nowiki></pre>, which results in
:{{cmdresult|foo}}
:{{cmdresult|bar}}
:{{cmdresult|baz}}

Alternatively, you can use <br /> at the ende of each line within one call, like this:
<tt><nowiki>{{cmdresult|foo<br />
bar<br />
baz}}</nowiki></tt>
, which will result in

{{cmdresult|foo<br />
bar<br />
baz}}

I have just got a MySQL problem when I edited a page, a query was not to its liking. It is quite easy to reproduce, just edit any page ;-)

History did get updated, and the page was also updated, so I have no idea what broke when that query failed.

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:
(SQL query hidden)
from within function "SearchMySQL4::update". MySQL returned error "1062: Duplicate entry ' ' for key 3 (localhost)".

H8s: 5-way navigation

I was just wondering what was happening with this, it would be really great for this to work.

Slashdot posted about [http://linuxbiometrics.com/ linuxbiometrics.com], and I found [http://linuxbiometrics.com/modules/newbb/viewtopic.php?topic_id=8&forum=1 this forum post there].

--[[User:64.180.113.159|64.180.113.159]] 23:27, 10 Apr 2005 (CEST)

There is a possibility that a beta program will be occuring around August or Sept. this year '05. Keep your eyes (or news aggregator) on linuxbiometrics.com for the latest announcements.

== Fingerprint reader hiccups ==

any body else notice that the fingerprint reader doesn't work very well or doesn't work at all if you have been using the notebook for sometime?

I'm thinking because of the heat generated from the hdd

== 5-way navigation ==

The ''5-way navigation'' mentioned in the [http://www.upek.com/support/pdf/UPEK_flyer_TCS3_TCD4.pdf spec sheet] sounds interesting.

===Integrated Fingerprint Reader===
IBM released a second generation of T42 models in Autumn 2004 featuring Intel Pentium M 765 processors and an integrated fingerprint reader.

The fingerprint reader is produced by a company called UPEK, which specializes in the manufacture of fingerprint readers. It is integrated as an USB device, and does all the matching in hardware, making it rather easy to use. Furthermore, IBM states that there's an interface with the [[Embedded Security Subsystem]].
</div>

==Linux Support==

There is a new GPL driver here: http://pavelmachek.livejournal.com/25060.html

A closed source driver from the vendor has been released. It interfaces to the hardware as a user-space USB driver through {{path|/proc/bus/usb|}} and provides a BioAPI 1.10 device, which can then be interfaced to pam for authentication by user programs. The driver can be downloaded from http://www.upek.com/support/dl_linux_bsp.asp; see the [[How to enable the fingerprint reader|corresponding HOWTO]] for detailed instructions.

Thermal Sensors

2006-02-17T00:36:28Z

{| width="100%"
|style="vertical-align:top;padding-right:20px;width:10px;white-space:nowrap;" | __TOC__
|style="vertical-align:top" |
This page aims to summarize known information about the locations and properties of thermal sensors on ThinkPad laptops.
|}
==Accessing the sensors==
===ACPI system temperature sensors===
The primary means of accessing the thermal sensors is through the [[ibm-acpi]] module, which provides up to 11 thermal sensors (some of which may be inactive) when loaded with the <tt>experimental=1</tt> option. Up to eight thermal sensors are exposed at {{path|/proc/acpi/ibm/thermal}}:
:{{cmdroot|cat /proc/acpi/ibm/thermal}}
:{{cmdresult|temperatures: 44 41 33 42 33 -128 30 -128}}

On some models there are three additional sensors at Embedded Controller offsets 0xC0 to 0xC2, which can be read by parsing {{path|/proc/acpi/ibm/ecdump}}:
:{{cmdroot|perl -ne 'm/^EC 0xc0: .(..) .(..) .(..) / or next; print hex($1)." ".hex($2)." ".hex($3)."\n"' < /proc/acpi/ibm/ecdump}}
:{{cmdresult|40 48 43}}

===HDAPS temperature sensor===
The [[Active Protection System]] accelerometer also reports a temperature (but it is not certain that the sensor location is inside the HDAPS chip):
:{{cmdroot|cat /sys/bus/platform/drivers/hdaps/hdaps/temp1}}
:{{cmdresult|41}}

===Harddisks temperature sensor===
Finally, the hard disk temperature can be read through the disk's SMART interface:
:{{cmdroot|smartctl -A /dev/hda | grep Temperature}}
:{{cmdresult|194 Temperature_Celsius 0x0022 145 097 000 Old_age Always - 31}}

Or, for SATA-equipped models running a recent Linux kernel (see [[Problems with SATA and Linux]]):

:{{cmdroot|smartctl -A -d ata /dev/sda | grep Temperature}}
:{{cmdresult|194 Temperature_Celsius 0x0022 145 097 000 Old_age Always - 31}}

==Sensor locations==
This information is model specific.

===ThinkPad {{R51}}===
The [[ibm-acpi]] documentation includes the report by Thomas Gruber:
EC offset Index in "thermal" Location (estimated)
0x78 1 CPU
0x79 2 Mini-PCI
0x7A 3 HDD
0x7B 4 GPU
0x7C 5 Battery (main)
0x7D 6 Battery (device bay)
0x7E 7 Battery (main)
0x7F 8 Battery (device bay)
0xC0 none ?
0xC1 none ?
0xC2 none ?

===ThinkPad {{T40}}===
The location of one of the sensors is identified [http://forum.thinkpads.com/viewtopic.php?t=11574 here].
EC offset Index in "thermal" Location (estimated)
0x78 1 CPU
0x79 2 System board under rear left corner of Mini-PCI module

0x7B 4 GPU
0x7C 5 Battery
0x7D 6 n/a
0x7E 7 Battery
0x7F 8 n/a
0xC0 none n/a
0xC1 none n/a
0xC2 none n/a

===ThinkPad {{T43}}, {{T43p}}===
Found by Shmidoax using cooling spray to cool down components and observe the effect on the sensors.
EC offset Index in "thermal" Location (estimated)
0x78 1 CPU
0x79 2 Between PCMCIA slot and CPU (same as HDAPS module)
0x7A 3 PCMCIA slot
0x7B 4 GPU
0x7C 5 Battery (front left)
0x7D 6 n/a
0x7E 7 Battery (rear right)
0x7F 8 n/a
0xC0 none Bus between Northbridge and DRAM
0xC1 none Southbridge (under Mini-PCI card, under touchpad)
0xC2 none Power circuitry, on underside of system board under F2 key
