Lenovo G460 Update Bios ?

2017-08-22, 0:39 AM

Good evening.
I have a Lenovo G460 20041 its cooler turns 100% on any task up to idle.
Reading some texts on the internet some people recommend to upgrade to Bios and give unofficial source links do not like to use this type of link
Would you like to know why Lenovo does not provide update for Bios of this notebook?
Update to Bios is solution for the cooler to turn 100% full time up in Idle
Could someone give me a tip of what to do
Thanks for listening.
 

 

Bios update is not required for this product - Notebook, Desktop

I would not expect your machine to flip pancakes.

I would not expect any BIOS update.

Do you have a 460 or 460E?

See Majestic post below for BIOS update in EOL support.

Good afternoon
G460 only has no Letter E on its label.
I at the official site also can not find Bios to update in Find Your Product
Only has G460e that is not my model.
Reading some tutorials on high rotation of the cooler in the model g460 is indicated the downgrade of Bios or update so that cooler does not keep working at maximum speed all the time.
I would download the Bios file from the Official site.
Thanks for listening.

I would download HW monitor from here and check sensor temps.

http://www.cpuid.com/news/55-hwmonitor-1-32.html

 

Due to the age of your machine (circa 2010), you may have other issues.

(1)dirt inside fan

(2)thermal paste has worn out

(3)something causing high machine temps, etc. 

(4)defective sensor

 

I do understand SOME BIOS updates fix excessive FAN ON.

See post below for latest BIOS.

Welcome to the Lenovo Community Gave !

 

Along with Sclexman's advice there is a BIOS update available for the G460 model.  Due to the age of the laptop all the downloads for that model have been moved to the Legacy EOL Support area which can be found at the link below.....

 

https://download.lenovo.com/eol/index.html

 

BIOS version 38 is the upgrade available for download  and it includes the following fix.....

 

Summary of changes
==================
General Information:

29CN38WW

Fixed fan always running after waking up from sleep

 

For your reference, the BIOS upgrade's README can be found at the link below....

Majestic is my fan to run full time after this update you deserve a prize
I removed a doubt this repository where this Bios file is from official source ie from Lenovo I can download without fear right
Thanks for listening.
 
 I stress that I cleaned the cooler and changed the thermal paste in June of 2017
I even broke the fan of the cooler trying to open to lubricate the bearing of the cooler to reduce the noise.
I will turn on the machine to put the new cooler and post the tests here the temperature with old cooler was not more than 38 ° in idle plus I will run hw monitor and post the result here.
I'm going to run the HW monitor with the new cooler that bought a 5v 0.40 adda to reduce the noise.
I stress that I bought a new cooler to reduce the noise.
Thanks for listening.

The Legacy EOL download section is an official Lenovo Support site.  No need to worry.

Being with NIWEx215_X64 downloaded is just running on the right machine need to be connected to the web to do the update?
One last doubt is it possible to do the update for the bios itself outside the windows or in some qflash programs ?
If you have correctly entered this NIWE file, it downloads the BIOS so it is not necessary to have a hash test to verify the integrity of the NIWEx215 file.
Thanks for listening.
