Sure, just send me a private mail.  But the discussion might be
interesting to others, so I really don't see the problem keeping it on
the list.  Anyone not wanting to see it can just kill/ignore the thread.

Any chance I can contact you directly somehow ? using the list is a bit
bulky, im somewhat tech savy, to the extent that I managed to replace the
LCD screen myself, so I should find my way around my x301, but still a
couple of areas are somewhat shady.

hey man ! 

Thanks for your reply , I've been activelly using hardware mainenance manual
in the past, so very well familiar with the document, but as far as Im
concerned there were no detailed information regarding antennas. 

I will try to follow your tips, hope fully that should do the trick .

As you may know, the support for the touchpad part of this keyboard has
just been incorporated into Linux-3.4.  The author of that driver also
has/had a tentative driver for the trackpoint part, making it appear as
a joystick.  I've used his touchpad driver for many years, but have
never tried his trackpoint driver, but you may want to contact him to
see if it might provide the features you need.

Hey man ! 

Great job on replacing the card. I'm looking to do exactly that, however I'm
confused with a couple of things. Do you think you could possibly help me
out a little bit here ? 

I currently have intel wimax-wi-fi card, which I would like to keep, since
sierra card does not have wi-fi capability. But then here is the problem, I
need to be able to plug in both card and both should be connected with
antennas one way or the other. 

I looked through the other thread regarding using unauthorised cards, and
no, im not doing any modification to my BIOS, I d rather use TAPE for that
matter, but I'm still confused which slots is which, so if I want to keep my
intel wimax-wi-fi card, and have all the antennas connected correctly, which
slots should both cards go ? And how antennas should be connected ? I
understand that there are more antenna contacts which is normally in use,
from the looks it there are 6 actually (if im not wrong), which means I
should be able to connect both cards comfortably and use bo

I put what I got here: http://www.mork.no/~bjorn/thinkpad-lte/

Not much, but it might give some clues wrt antenna cable routing etc.
If you look closely at the pictures of the wlan card and the wwan card,
you will see the cables for the wlan card being routed through a hole in
the mainbard next to the wwan card.  So moving any of the cards to the
other socket should not be difficult if you want to try the tape trick
before modifying the BIOS.

I recommend downloading the "Thinkpad X301 Hardware Maintenance Manual"
from Lenovo. It explains a lot of details, including where to find the
different slots.


I believe that should be no problem.  There are 3 mini-PCIe sockets in
the X301:

 a) wlan (full size)
 b) wusb or Intel "Turbo Memory" (half size)
 c) wwan (full size)

Socket a) and b) are located behind the same cover as the memory slots.
Socket c) is located under the upper left part of the keyboard.  There
are 6 antennas.  In my X301, 3 of these were connected to the Intel wlan
card, 2 were connected to the Ericsson wwan card and 1 was not in use,
taped in place between the memory sockets.  But do note that the two
locations are both in the upper left part of the PC.  Any of the antenna
cables can easily be rerouted to either location by simply pulling it
through to the other side of the main board.

I assume your wimax card replaces the wlan card in my setup?  And I
assume it uses maximum 3 antennas?  If so, then you should have no
problem k

Powertop tunables

Sergi Pons Freixes — 2012-05-18T09:26:08

Hi All,

PowerTOP 2.0 has been recently released [1]. I've seen that it now has
a tunables section where you can turn on/off several optimizations.
When running only with battery, I don't hesitate to turn of all of
them on, but I'm not sure when I'm running on AC.

Do you know if any of the tunables can have an impact on the
performance of the laptop?

Regards,
Sergi

Hm, syslog does not record any attempt to shut down... How else can I

Yes, various threads point to power management, but what in my case the 
shutdown requests appear with or without battery and with or without 
mains adapter. Plus I tried to disable the advanced power management 
from the BIOS which had absolutely no effect.

Re: Unsolicited requests for shut down

/var/log/syslog  should have the request although it might not help. 
Notice that the overheat can still be the motive albeit the laptop is not 
overheating... but the sensors (or something else) are giving misreadings.

Re: Unsolicited requests for shut down

Athanasios Velios — 2012-05-16T12:31:57

I had Psensor installed for a while and the temperature readings did not 
seem to make sense. For example, as soon as I turned on the computer and 
the temperature was still low, I would start compressing files and the 
Shut Down request would come up. By cancelling and carrying on, the 
temperature would increase but no other request would come up. I do not 
think that the temperature ever went over 60 degrees C anyway and the 
cooling fan seems to be working as expected. Plus the motherboard has 
been replaced on this laptop for a different reason and the problem is 
there with both old and new.

Would any of the logs record the shutdown request, so that I can trace 
it back?

Re: Changing sensitivity ThinkPad USB Keyboard with TrackPoint

Richard Neill — 2012-05-16T11:58:41


Yes, I did. Xinput allows for the X-server to tweak things once the 
signal reaches it. This allows for middle-button as emulate-wheel, and 
horizontal scrolling. But the trackpoint "pre-amp" gain is actually 
controlled in the hardware itself, and requires writing commands back to 
the keyboard.

For a Thinkpad, this is:
echo -n 255 > /sys/devices/platform/i8042/serio1/sensitivity

For the older USB keyboards, there is no way to do it (as yet)

For the new USB keyboard, the tpkbdctl program works.


[It's possible to fake it slightly using mouse-speed and acceleration, 
but this reduces fine-control. Turning up the analog gain is better]

Re: Unsolicited requests for shut down

overheat? what is reported by sensors, for instance? you can put a script 
running in the background, with watch, for instance, to dump sensors to a 
file every 1 min. when you reboot you can inspect and see what were the 
temps when you were shutdown.

from the top of my mind that is what your problem makes me think off

Unsolicited requests for shut down

Athanasios Velios — 2012-05-16T09:48:14

Hello,

Since February I have a strange problem on my Thinkpad X220 Tablet which 
runs Linux. When there seems to be a lot of activity (e.g. backing up or 
compressing files) the OS requests to shut down as if I chose Shut Down 
from the menu. This happens with different distributions (I have tried 
Ubuntu 11.10 and 12.04 and the current Fedora). I am not sure where to 
look for possible errors. The logs do not show something obvious, but I 
may not be looking at the right place.

Any ideas?

Thank you,

Thanasis

Just to make sure: You did try to configure it using xinput, right?

$ xinput list-props 'TPPS/2 IBM TrackPoint'
