Re: Dell Precision M6600, Optimus and DVI/Displayport not initialed at boot time

A late update to my previous post above. My main problem have now gone. The HDD password dialog shows on the displayport screen during start up. However, the Dell logo do not show during start up and the computer refuses to enter BIOS setup even if the right key is pressed. When undocked and not connected to an external monitor the logo shows and I can enter BIOS setup.There are no problems waking up from system sleep.

I'm not sure what did the trick (the changes happened a couple of months ago). I have not done any hardware changes or manual driver updates...
