@rzrfreefr,

The G470 fan is running at 100% all the time? or just running normally all the time?

Have you tried updating the BIOS?

so we will try to work it out

yes I did update BIOS couple of days ago

from 40CN22WW(V1.09) 02/18/2011)

to 40CN23WW(V2.09) 06/20/2011

Can anyone confirm that issue ? I also noted some reports about those fans at :

hi

I did install hwmonitor_1.18-setup.exe 

but the fans RPM are not gathered

I suspect this is a BIOS restriction

I think there is a bug on some sensor : TZ00 report 0C 

Are there any G740 owners who can check if hwmonitor also report temp=0 ? 

anyway the fan seems to run slower than on linux but I dont think it ever stop ... 

If it maters I made a screenshot at :

Can we hope a BIOS release that monitor fans speed and fix other ACPI glitches reported by fwts :

Hey me too, the TZ00 is at 0°C.

Lenovo G470 model 4328-2CY

[rzrfreefr]

hi

where did you get this "4328-2CY" number ? tell also your BIOS version ? do you run gnu/linux too ?

I think about creating an other thread specific to this "TZ00 bug" , or may the admin do that

looks that it is also affecting others see screenshots at :

hi

my BIOS is  40CN23WW(V2.09) 06/20/2011 and i'm running Ubuntu 10.11. 

the $sensors throws me this:

acpitz-virtual-0
Adapter: Virtual device
temp1:         +0.0°C  (crit = +127.0°C)

and nothing else... Do you know any program that can control the temp. and fan speed?
