We have just had a 3 week old HP probook returned to us as the display is both upside down and flipped!
We have reset the rotation settings, but the panel on the laptop is still reversed 180 degrees (like a projector set for back projection!).
It does this in bios as well as windows, and reseting the BIOS to defaults has not fixed it.
External displays are fine!
Any suggestions (other than throwing it through the window?)
