Re: Replacing G570 fan

[ Edited ]

AS stated before the fan does cuts off at 43C ... but during normal use temps never go that down .. similarly if put system to sleep even for 2 secs and power on .. fan goes off ..it reactivates @ 56C and then never stops until temps drop down to 43-42C

 

I urge other users to please check if their fan cuts at 43C or not OR try the sleep/awake to see if fan goes off like mine,

 

AND i urge lenovo support to release a BIOS fix to solve this problem

Re: Lenovo G570 Fan issue

Fan turns off when to sleep and power it back.
Then turns on when the temperature reaches 56 ° C

Re: Replacing G570 fan

I want to confirm this exact behavior on my g570.  The fan has been noisy and constant since I got this laptop many weeks ago.  I thought it was a problem with Linux power management software, so today I went and installed lm-sensors and powertop and found that the cpu temps were in normal range.  This laptop has never been booted into Windows so it is definitely not a software problem.  The exact behavior specified happens under at least 3 different Linux distros: Fedora 13, OpenSuse 11.14 and Linux Mint 12, using two different kernels, 2.6.* and 3.0.*

 

The problem is that having the fan run *constantly* severley shortens the battery life.  At full charge I can only get about 2 hours.

 

fan turns on at 56c, fan never turns off (because normal running temps never fall to 44)

sleeping stops fan until 56c is reached again.

 

I feel that 50c should be a good cut-off for the fan, or at least a break point to turn it to low.

 

# sensors

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +50.0°C (high = +80.0°C, crit = +85.0°C)
Core 0: +48.0°C (high = +80.0°C, crit = +85.0°C)
Core 1: +41.0°C (high = +80.0°C, crit = +85.0°C)

 

This is definitely a BIOS bug.
