Re: Lenovo U41-70 brightnes level get stuck

Hi there, Jating –

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

try going to bios. Use the function keys to adjust the brightness. Can you make the adjustment?

 

Update us how it goes.

 

 

 

Regards,

Re: Lenovo U41-70 brightnes level get stuck

whenever the brightness button(f1 and f2) gets stuck i have to go through this hectic method and restart it. I use windows 8.1 and the brightness doesn't get fixed even from windows charm buttons

For getting the brighness buttonn work again i used these following steps.:-

 

a. Press Windows key + R

b. Type 'devmgmt.msc' and hit ENTER.

c. Expand “Display adapter” option.

d. Right-click on the “Display adapter" and click on “Update”.

e. Restart the computer once the driver is update.

 

kindly tell the solution ,really disappointed by my new machine.

Thank you

Can you just roll back drivers through device manager?
