As above - ive just bought this second hand....i always clean build my laptops/pc's with an oem image so i know its clean. Ive just built with 1903 and used all of the dell drivers and it will not auto rotate or go into tent mode. The device manager is clear (everything installed) and the latest sensor driver is installed also. I think it sees the laptop as, just a laptop as the auto rotate function in the quick list isnt there. Ive also tried the registry to forcefully activate those options with no luck.
Ok - so after a reboot and i have no idea why....ive now got an auto rotate button in the quick find area on the right...but, its greyed out...anyone have any idea how to sort that???
So, moving on....if i flip the screen over the auto rotate unlocks but then relocks if i flip it back round. Also randomly if i fold it back on itself it puts it to sleep. Rebuilt again, and now no rotation lock again. Not at all impressed with the fragility of this system. On this rebuild ive kept it off the net and used dell only drivers. Still no fix.
PM'd you but forgot to put my Tag in and...say hi and thanks very much for helping....in the meantime im going to try and older build of windows....
Just thought id update my thread. Ive still not got it working but, ive got a little further. Im working from an OEM build of windows (just so everyone knows)
Ive got the rotation lock to appear again in the quick find on the right. To get this (not necessarily in order) i did this...
1. Went to regedit to here...
In there i was missing the key REG DWORD SensorPresent - created the key and set the value to 1
Then i went to the services and (for me) all the sensor services were set to manual and off. I renabled the all services and set them to auto start. Rebooted the laptop and now i have the rotation lock button.
The problem i am now faced with is, if im in the normal mode as a laptop - the rotation lock is greyed out. If i then flip it into tent mode the rotation lock free's up, but, nothing happens....no auto rotate into portait for example. So, thats as far as ive got. Infuriating but learning all the time.
