After Windows 10 upgrade, my laptop appears to be running flawlessly except one major annoyance: the screen no longer auto-rotates when in tablet mode. This is a convertible PC, so this basically renders tablet mode useless.
Fully updated system prior to installation of Win10
After upgrade, I updated all of dell's applications, drivers (one exception, see below)*, and bios.
Display settings - "Lock Position" is turned on permanently (greyed out, cannot adjust)
*When I try to upgrade the video driver, it fails because the recommended driver update for my system (July 23rd, 2015) says its older than the current version.
I suspect this is a driver issue. Should I go ahead and install the older driver? I know Win10 just rolled out so I expected a few hiccups but I was surprised to find very little info about this issue as of yet. I use my laptop as a tablet quite frequently, so I would like to find a solution to this problem quickly. Thank you all for your help!
Thank you so much for this solution!
Also as a side note for others with this issue: Obviously, this is not a video driver issue like I initially suspected. However, if you believe you do have a driver issue, the driver which controls auto-rotation will be a Dell Application driver for your 3 axis accelerometer. This different from the video drivers for your system.
Good luck all and thank you again!
My rotation lock is also greyed out in laptop mode. Switch to the easel mode (keyboard under) and the rotation lock button in the action center should be ungreyed out.
Apparently, Windows 10 thinks you should not be clicking on the rotation lock while in laptop mode.
