great now I'm at 2.09 because the stupid program didn't make a backup for some reason. I followed the guide and it didn't back anything up once my laptop started back up. Well back to hoping Lenovo will get off it's lazy ass and release the already out bios

I've been asked to report input to lenovo but no answer yet ...

The odd stuff is that we know the solution to this problem ,

there is a DSDT bug in the bios and have the fix to be integrated (for free) ... 

 

Do you know alternative place to make us heard ?

Does that ACPI/DSDT fix really fix your fan noise problem?

 

T420s users are having the same fan speed problem! 982 forum posts on this problem, and very few details coming back from Lenovo: http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T420s-Fan-noise-Issue/td-p/443569

Re: Replacing G570 fan

Hello,

I took 3 days with the lenovo G570. The version of BIOS you have is 2.14. Watching, I could realize that my computer connect and turns the fan off. The range of values ​​is:

Fan On: 59 º C-60 ° C
Fan off: 38 ° C-39 ° C.

This range also varies with time. For example, is often not yet reached the value to turn (59 º C-60 º C) if you spend about 10 minutes "standing" is turned on again and stops again until it reaches 39 º C.

Another thing I've seen is that the CPU is always busy, the laptop runs on Windows 7 64 bits, the process "system" always takes values ​​between 7% and 20% of the CPU.

Sorry for my English I am Spanish
