Ideapad Z500 Touch Win 10 Brightness Problem

2015-07-29, 20:45 PM
Hello,
the Z500 Touch has/had the problem with the regulation of the brightness with Win 8.1, but reinstalling the intel video driver solved this problem.

Now - with Win 10 - I have got the same problem, but reinstalling the (intel) drivers doesn't help. I just can't regulate the brightness: The brightness sticks at the lowest level.

Does anybody know how I can solve this problem?

Peter :)
Solved! See the solution

My z500 (not touch) also has the same problem, it is very annoying.

I hope you solve this soon, as you are advertising Windows 10 everywhere in your web....

We're discussing the same problem on the spanish forum -> https://forums.lenovo.com/t5/Z/Z500-y-Windows-10/m-p/2130659#M4247

It seems modifing regedit can help this issue, as on W8.1 https://forums.lenovo.com/t5/Z/Solucion-al-problema-de-brillo-en-Windows-8-1/m-p/1414649#M3567

Thanks! that worked for me, but just using this driver (beta for w10)

https://download.lenovo.com/pccbbs/mobiles/win10beta_g1dt001w.zip

 

Z500 is not in the compatibility list of this driver pack, but it works.

It's funny because both of the two options don't work on me hahaha

I have another issue. None of my internet explorers (edge, firefoz, chrome) open some webs like google, twitter or facebook. The only one which works is maxton. I think that could be a problem with the spybot, but I desinstalled before I updated, so I don't know. Any ideas?

I'll try that.

 [Edit: Doesn't work for my Z500 touch. I copied those files but it didn't help. In addition, I'm not ableto reinstall the Win 8.1 Intel Video driver, because Windows 10 tells me the Realtek bluetooth or something like that program doesn't run with Win 10 :/]

 

I've got another solution: Just set the driver of the on-board graphics to the previous version and the brightness problem is solved, but because of me having a graphics 4000 the performance with this "trivial" driver is just bad so that it's just a workaround.
