XPS 13 brightness has completely stopped working

I am completely unable to adjust the brightness of my XPS 13 laptop through either the keyboard buttons or the control panel slider. Repeated attempts to make the brightness keys respond will freeze the computer for a few seconds. Bizarrely the pop up slider that is displayed still works, it just in no way reflects what is actually happening.

g.becattini,

Reinstall the chipset drivers, reboot and then install the video card drivers back into the system. If that does not work roll back the previous windows update.

Choose your system from the link below to download the drivers.

Re: XPS 13 brightness has completely stopped working

I found a workaround that seems to get this working again.  I went into the BIOS and under the brightness setting increased the brightness setting for the screen to the maximum for when it was plugged into power.  Saved that and restarted and now I can adjust screen brightness again using the F12 and F11 keys.

I downgraded the driver to the old Intel-HD-620-and-Iris-Graphics-640_JK74J_WIN_22.20.16.4708_A06 and now it works.

I uninstalled the last Windows update and my brightness control is back. Hopefully forever. Simple fix here.
