For anyone looking for a solution to at least the screen brightness setting being stuck at/defaulting to 40%. You need to uninstall Intel Dynamic Platform and Thermal Framework and then you will gain back control of your screen brightness
Also check these settings, Control Panel> Display> Change Display Settings ensure that the "Allow the screen to auto-rotate" is selected.
Kindly get back if there are any further queries.
For me to better assist in troubleshooting, please click my DELL-username and send me a Private Message with the Dell Service Tag number and your email address.
That's right. You will need to stick to version 8.1.10605.221 to maintain control of the brightness settings. I originally used the DPTF from Windows Update as an alternative to 8.2.10900.330 but that would cause various power and thermal management errors on the 5175. So just stick to 8.1.10605.221 until they fix it.
Sad thing is, I only had to do a factory reset, and install drivers one by one to find a solution to this (sarcasm intended). It's unbelievable that Dell does not have a solution cataloged for this issue as I assume many will be using version 8.2.10900.330 with the associated issues.
Your description of the fix was a bit thin on details but was enough to go on. I posted more details to make it easier for other people with the problem to fix it.
I spent a fair amount of effort trying to fix the problem (including a reset) and the machine was scheduled for another trip back to Dell.
If you are missing "Sensors" in "Device Manage", you need to install the drivers for that before updating/changing the "Intel Dynamic Platform and Thermal Framework" driver.
You can pick the driver (and select an older version) through the "Find it myself" tab on the "Drivers & downloads" page.
After the last BIOS/Firmware update, the auto-rotation button became unavailable. Now everything (BIOS, Firmware, drivers, Windows Update) is new. Today I ran Dell SupportAssit and WindowsUpdate.
