I upgraded my XPS to Windows 10 and have problem witch changing brightness ( same problem witch w8 when upgraded drivers).
Dell what can I do right now??!!
On Product page i get information:
Dell has tested this product to confirm that it can upgrade to Windows 10.
But it not working. Tested!!!! 100% brightness drain my battery!!!!
31.07.2015 - i seen new drivers on support page. Downloading ...
Solved! Go to Solution.
I found this solution on another thread regarding the same issue. I've confirmed that it works on the XPS 14 L421x with the latest Intel HD Graphics 4000 drivers (10.18.10.4276) for Windows 10. All you need to do is modify one registry value. Here are a few different methods you can use.
Method 1) Batch File (quickest/easiest)
Method 2) Elevated Command Prompt
Method 3) Registry Editor
Feel free to contact me if you run into any problems.
On a side note, Dell could easily release an official hotfix based on my attached batch file. It would mean a lot to customers who aren't comfortable with forums.
Essentially it's a bug with the Intel graphics drivers.
I just upgraded my own Dell L421x to Windows 10 and found two solutions, both of which are suboptimal. Pick one or the other - I went with #1 after finding #2 meant I couldn't get the Edge browser to start.
Workaround 1: Install very old Intel Graphics 4000 drivers: This gets you your brightness controls, but you will probably see some form of instability because the drivers are so old.
Workaround 2: Use Microsoft Basic Display Adapter This doesn't involve old software, but you end up losing a lot of multimedia options.
If you don't like either of these options, I did notice that the screen brightness ends up locked at the point when the broken Windows 10 Intel driver is installed. You can temporarily switch to the "Basic Display Adapter" to lower your brightness, and then reboot your computer. The brightness should be around the point where you rebooted your computer. e.g. If you set brightness to ~30% when the not-broken driver is installed, and then switch to the broken driver, your brightness will end up locked at 30% instead of 100%.
I know it's all ugly, so hopefully one of Intel or Dell gets the drivers fixed up.
Installed newest drivers from dell site - still brightness not working 😞
@patrickceg thank for solution but it cant look like this. We pay and we want working!
@pejot I was able to get brightness to work after installing the Windows 8.1 driver (10.18.10.3262). The 3262 driver will work even if you have already installed the Windows 10 driver.
The file is called Video_Driver_VJH9H_WN_10.18.10.3262_A00.EXE
You can download it directly from this Dell link.
I have the same laptop and the same issue. Previously with Windows 8.1 I had the same problem and I just installed the older Intel driver from the dell website, which worked for me, but now even downgrading doesn't help. Please do something. Maximum brightness hurts my eyes!
Same problem for me - I can't believe we have to deal with it! I don't want to choose between brightness and performance and I'm really unsatisfied for that!!! Does Intel knows about this, are they going to fix it?
Same problem here with my XPS 14:
- With Windows 10-Intel-Driver I can't change brightness
- Downgrade to Dell-Intel-Driver for Windows 8.1, I can change brightness again, but I always crashes after energy saving mode/ disabled screen
Beside, as soon as you downgrade a few minutes later Windows 10 automatically updates the driver. Only chance is to disable auto-updates for windows 10 - but than I get no updates at all anymore 😕
Dell, pls help with new drivers!
@Dennis2015, after Windows automatically upgrades the driver go to Device Manager, select Intel HD Graphics, right click and go to properties, then roll back the driver. It will roll back to the 8.1 driver and won't auro-update.
I have uninstalled all the graphic driver and the video cards (both Intel and Nvidia), deleting them all, then I restarded the pc. Now on Device Manager I see Nvidia GT 630M and Base Windows graphic video, but everything works well. I hope....
