Re: Z500 brightness problems Windows 8.1

Hi Guys,

 

Looks like I can now safely upgrade from Win 8 to 8.1 on my Z500. My previous upgrade from Win 8 to 8.1 in early Oct caused my Microsoft Store Icon and some other apps to malfunction and the solution I got from forum was to revert (downgrade) back to Win 8.

 

Now that I read all the posts of brightness issue with Win 8.1 upgrade and issues resolved, I will proceed with my upgrade. Any comments on the upgrade would be appreciated.

Hello, Im having the same problem with the P400 touch. Do you know, since they are "sister" products, if downloading the driver will help solve the problem?

Thank you. it works!.

however, it is worth to note that this is still an older version, at least identified by the system as "older than exsiting" during installation.
