Still stuck at max brightness

2019-12-07, 14:50 PM

I am so upset with Lenovo for making spend 2 hours on the phone with tech support over this.  Not for an almost $3k machine, this is insane :(

Re: P1 Gen2 brightness control not working

Should I be able to load DCH drivers off the Intel site or does Lenovo whitelist drivers? I keep getting "operating system not supported" errors when attempting to install new Intel GPU drivers.

I am new to Lenovo and new to this forum, I joined plurely due to the fact my virtually brand new P1 gen 2 is experiencing the same issue.

 

I am unable to change the brightness dispite having tried a few of the fixes listed here. The issue started right after installing Intel Graphics Command Centre.

 

Looking forward to Lenovo fixing this asap as the laptop is virtually unsuable is many enviroments due to this simple problem.

Here is the new driver to fix the brightness problem:

n2odr09w.exe

 

It will be released to the website later this week but I wanted to put it here for now.  I confirmed, after installing this driver and reboot, the brightness control starts working again.

Did you previously try installing some driver from Intel website?  Can you post a screenshot of the error?

As of today, there's an updated Intel graphics driver in the P1 Gen2 driver list:

readme - https://download.lenovo.com/pccbbs/mobiles/n2odr09w.txt
driver - https://download.lenovo.com/pccbbs/mobiles/n2odr09w.exe

 

HTH.
