T14 Gen 1 BIOS update to 1.17 made fan work loud all the time

2021-02-18, 17:32 PM

The latest BIOS update (N2XET27W 1.17) made my T14 Gen 1 fan work loud all the time. With or without any load. I go crazy a bit because of this noize.

 

I know there were some issues related to BIOS update reported some time ago. For different Lenovo series. And the best advice was to downgrade BIOS.

However the current version 1.17 states it's impossible to downgrade.

 

Any advice here?

 

Thanks,

I think the model is not the same. Mine has 1.17 as the latest version. See screenshot for more info: https://prnt.sc/100456e

Good day.

From your prior posts, it looks like you may have a T14s gen1. That is a different device than what this thread describes, a T14 gen1. Hence there is no correlation between BIOS packages/versions. It is important to keep these differences in mind.

 

Thanks.

Just mentioned that on a battery the laptop works fine and silently. Same as before.

 

Only AC mode got constant fan noise - right after the BIOS update.

 

I've also Checked BIOS confg. 

 

Intel SpeedStep Technology: Enabled

Mode for AC: Maximum Performance

Mode for Battery: Battery Optimized

 

Adaptive Thermal Management:

Scheme for AC: Maximize Performance

Scheme for Battery: Balanced

 

This config was not changed manually for sure.

 

Could someone share the default values for Mode for AC and Scheme for AC, please?
