Re: Lenovo G560 problem with fans

2011-09-16, 13:33 PM

Was idle in safe mode for about 10 mins, CPU usage between 0 and ~7% (Win7 x64)... same deal with the fan. Mine came with the latest BIOS (1.07). The drivers and apps (like Energy Management) I'm using are the latest, as provided by Lenovo on the website. I believe it's not driver or O/S related, probably BIOS, just my $0.02, but I'm no expert. I've been thinking... Since it's an E-350 APU, even with the fan always on temp never drops under 46*C. I guess they just run hotter than other chips so the fan not ever stopping would make sense, but I don't know what the safe temp is for this chip... Core Temp reports a Tj. Max. of 115*C. A *tad bit* lower RPM would go a long way...

/offtopic: Also, it would be nice if the "Battery Runtime/Battery Health" feature would be incorporated into the BIOS, thus everyone could benefit from it, no matter what O/S they are running.

IMO fan problem is related to CPU and GPU, not only to CPU. It's because of the same heat-sink for CPU and GPU chips. Basically nvidia m310 never goes under 55C especially when win aero is on. It would be nice to have some "slowing down" option for the gpu and then, IMO, overall temps would go lower. I already tried newest nvidia drivers and slow down the chip, memory and gpu but it didn't really help.
I tried putting new a thermal paste on cpu and gpu and it lowered the temps by 2-5C each.
But anyway, the fan is always on, even when only Opera and basic system software is running.

Ok, so it makes sense for us peeps that run nVidia or AMD chips. But fans that don't slow/stop for Intel-equipped notebooks... =/

This problem happens on my g570 with bios 2.07 and 2.09.

 

I think this is a problem with the insyde EC, not the bios.

 

I installed an unlocked bios which opens all configuration options.  I modified the first fan trip point from 55c to 60c.  This changes the time the fan turns on, but not off.  The ACPI code (DSDT) does not receive any _OFF call backs ever, only when the laptop is put to sleep  (and then it gets _ON and _OFF sent one right after another)

 

After putting the laptop to sleep with the new 60c BIOS settings... after waking up the 55c setting takes over.  So, it's not the BIOS.  The BIOS settings are overwritten after a wake event and the ACPI code is largely ignored.  That only leaves the EC.

 

Also, after updating to 2.09 two of my active cooling trip points were removed from ACPI (not that they were honored by acpi at all anyhow)

mark2 - There is no one at Lenovo who can understand your message so it will be ignored. They probably outsource the BIOS and EC to a Amateur Engineering Company.

 

secouver - There are many before you and many after you who have returned their laptop. Smart move. However, Lenovo doens't care, and I don't know why. Maybe they don't get the message.One giant bureaucracy.

Re: Lenovo G560 problem with fans

Hi @ all,

 

a colleague of mine has the same problem with his G560. I have update his bios and EC to 2.15. Both Versions will be displayed in the bios screen but the fan doesn't run slow mode. The fan always run with full power.

 

I've read the complete thread (lot of work :-P) to get a solution but I can't find it.

 

Did Lenovo still work on the problem or do I have fail the solution in this thread?

 

Can someone give me some information about the status of the problem please.

 

EDIT:

 

Have nobody a solution?

 

Can someone give me some old Bios versions to try a downgrade? 2.03 or something else.

 

 

Thanks for your answers.

 

Best regards

erik
