Still no solution.

I have formated the computer downloading the OS from Dell tool.

Tried with latest intel drivers from Dell (13-Jan)-->Brightness slider stop working, brightness always at 100%.

Tried with intel drivers from intel website-->The same problem.

Only solution is to revert intel drivers.

Please fix this.

Is always the Dell support so useless? I have had to report this issue to intel, due to your incompetence...

I have the same issue, any fixes?  @jlmcr87 how do I roll back to previous driver?

jlmcr87 · Answer

Device manager-->Intel xe--> select go back to previous driver

jlmcr87 · Answer

I received a private message from Dell support where they say i had to select intel HD 4000 and install microsoft basic driver. First of all, this computer doesn´t have the ancient intel HD4000. It´s an intel Xe.

Second: why i should unistall a graphic driver to install the microsoft basic driver?

Please Dell support, be professional, be serious. Report this problem to your engineers.
