New Bios and embedded controller are available for t43/t43p

http://www-306.ibm.com/pc/support/site. ... 58597#bios

Bios: "(New) A new BIOS setup option, that allows system startup without pressing an ESC key on POST 2010 warning message."

Embedded controller: "(Fix) CPU thermal sensor adjustment. "

I installed the embedded controller update and... my fan is STILL always on at the highest level with CPU temp around 42 degrees.

Not much change here either.

System still comes up after reboot with a fixed level of 7. After waking up from hibbernation it's auto bios. With auto fan still kicks for the 0xC1 at 43°C as before (CPU was 39°C, GPU 41°C).

I can't say if the pulsating fan noise is probably gone, too loud at the office here. The RPM meter in my latest version (will release that later today) may indicate a more stable fan speed, but I'm not sure.

i done both.
fan is working non stop here with temp of 37degrees right now.

Fan just switched off at CPU 37°C and C1 at 41°C. That may be a new thing. (I think in earlier tests the C1 needed to be below 38 and that never happened).



Markus

Tried again and now it took the C1 down to 36 (all others around 33 ... I had put the machine outside the window at freezing weather).

Odd...

Link's dead.

Works here (clicked just a moment ago). But I guess you may just go to the download site and check the stuff for the T43. Two releases of today, Bios V1.24, EC V1.04


Markus

Yup, just updated... we'll see how it does. So far I think it's quieter!

*****Expletives removed by Moderator*****...but not for the t42...

I think the embedded controller update is just a placebo pill.

No improvement, fan is running all the time at 42 °C (T43 2668, 2 GHz, 14´ TFT, 300x, 1 GB RAM).

Verified no change.

Looks like my computer was on just to little before to give an accurate judgement.

Sounds just like it did before.

has anyone confirmed the 2010 error going away yet?

I can verify the option exists in the BIOS. No drive to test with.

Did anyone get rid of that pulsing problem of fan for T43? I haven't upgraded yet.

To Shimodax,
How can you know temperature of all sensors? I am one new guy and want to compare the change after upgrading. Thanks!

After a couple more hours here's my impression:

I think it got rid of the worst fan (when it's really high for no good reason well after it should have throttled down).

It's still on, a bit more than the T42's I've seen around. But it is an improvement.

Perhaps I'm looking to closely... I don't know. Just my observation after a few hours.

Hmmm... for some reason I am unable to install the update for the embeded controller. After restarting and following the instructions in the text based interface nothing happens. It is just trying to read some kind of program.

Does anybody have similar problems? I would really like to fix some of the fan problems with my T43P (2668-G2U).

Can't believe it... They put an option that allows you to choose that the boot process has to continue after the 2010 error msg but you can't disable it !!!

AFAIKT the option disables the error.

my fan runs continiously since i did the upgrade, but at low speed which doesnt bother me. cpu temp is around 36degrees almost all of the time something that i havent seen in the past.

Absolutely no change regarding the fan. It still goes up to high speed when turning the system on. It still triggers at the same levels and still pulses every few seconds while on.

Hi,

If I'm not wrong, what the BIOS option does is to allow the system to continue booting uninterrupted after displaying the "2010" error.

This is what I gather from interpreting the BIOS option..

Can anyone with a "2010" drive test this out?

And by the way (as best I can see no one has asked this question) what exactly does error 2010 mean? This may be internal to IBM, oops Lenovo. But that would simply make the information harder to get, not impossible.

I think what the engineers are telling us (being an engineer myself) with this patch (the 2010) and the form that it takes (passing over the error) is that the error is not material. And it was easier, in a short time-frame, to simply pass over the apparent error than fix the underlying problem(s). The underlying will fix will probably take the form of the T44 (alas).

Of course it would go a long way in explaining the materiality of 2010 if we knew what it meant.

I may be an engineer, but this is not just my first Thinkpad but this is my first laptop. a) what (where) does one need to learn the details of the fan stuff and b) how does one measure the so-called 'levels' etc? Is there a piece of software to do this?

Won't it jump to the T60 next Year?
Take a look at Shimodax's Fan Control...that gives you all the information you need for the Fan and Temperature Probes.

Hit 36 degrees C, fan stopped!!! T43 users somewhat can be happy about what IBM did on this now

FWIW, Shimodax's fan utility seems to run more slowly on my T43p after ths bios upgrade..

and i get the occasional "RESULT: could not set fan state" then after a few seconds, it usually DOES set the fan state..
for inswtance i just set the fan to "Level #4" or "7" and while it did give the error message and thereafter said RESUT: OK"

all the while the fan does not seem to change speed, much..

will have to try a reboot to see what happens..

edit:
the fan seems to behave itself, now..
lower speed, much more quiet..

I updated the BIOS and the EC, haven't noticed much of a difference when it comes to Shimodax's Fan Control Utility; but I have noticed that the fan has changed its behavior somewhat. Stops at lower temperatures and some other things, I will post back once I have had time to experiment further with everything.
