Re: G470 - fan running non stop

@rzrfreefr and ghertzan,

Appreciate if both can send me the following via private message so I may log a case to engineering on this.

Name:
Mobile:
Email:
Model Type:
S/N:

BIOS:
Win 7 Pro/Ulti/Enterprise:
Lenovo Energy Management:
Energy profile used:
Core #0 = 41c
Core #0 = 44c

AC and battery plugged in?

Also try booting up the laptop, leave it for 10 minutes, then check if the fan did slow down?

Re: G470 - fan running non stop

Hi everyone.

I bought a month ago a new G570. It looks great notebook accept for this problem. Fun never stops and it is really irritating. To be honest with you, the problem appear only at linux system. Not in windows. I have tried already two linux (ubuntu 11.10 and open suse 11) distributions and the problem is still there. If i wont find a solution soon i will try to sell my laptop and buy, perhaps a Dell one that support better linux.
