Cannot adjust screen brightness on Dell laptop? Simple solution.

I have this issue on my Dell Inspiron 13 7000 series for very long time. I tried searching Google and Dell support community and I did:

Control Panel > Device Manager > Display Adapters > Intel HD Graphics 5500 > Driver > Update Driver > Search Automatically.

It fixed.

18:35 on 25-Dec-2016: Sorry bro, I did as above; it fixed but when I try pressing the brightness button then It come back problem again: can not adjust the brightness. Hic hic

19:00 on 25 Dec 2016: I even try downloading and installing the latest Intel Graphic Driver (issued on July 2016), but just after a while, the screen comes back very dim.

I accidentally discover this: Setting --> Display --> uncheck the box "Adjust my screen brightness automatically".

Sorry, but stupid Windows!!!!

I had a problem that my screen was very dark when on battery, ie not plugged in   Despite exhaustive searching on microsoft, dell and throughout my computer, I was unable to find a slide bar that nearly every support blog says is there!  Finally, after nearly a year of frustration, my IT contractor told me to do the following:  immediately when powering on the computer, begin tapping the Fn F2 key.  Continue this for about 5-10 seconds until the screen shows up with a brightness bar that you can then adjust.  So simple, yet nowhere have I seen this posted.

Hope it helps others!  (Inspiron 5000 series)

Thanks, I had a similar problem (Latitude E6540, IPS display, stuck at brightest level) and reinstalling the driver in Device Manager solved the problem.

With regard to automatic brightness adjustment, I have also found that to be troublesome on a Windows laptop (HP, in my case).  The display would slew from bright to dim or vice versa in a few seconds, for no apparent reason.  It would be very frustrating to live with that for an extended period of time.

This worked for me! Dell Latitude E6540 and Nov, 2019. But updating the driver was the solution.

I had the same issue and the suggestion to update the driver under Device Manager didn't work for me (it would simply say the driver was up-to-date).  Installing Intel Graphics Command Center and adjusting the brightness from there worked (the brightness range goes from -60 to 100).  Also, I would recommend to install Dell's SupportAssist because it found newer updates to the graphics driver that a simple Windows update missed.

Letting it auto-update driver did nothing for me. 

My brightness buttons worked fine. But then recently, either the Dell or Windows auto-updates caused it to stop working.
