Ok, I have my mbp in clamshell mode and hooked up to a 23" ACD.. but when I take the magsafe connector off the 23" ACD display shuts off and the mbp goes to sleep... is this normal????
My Macbook works flawlessly with my 24" (same resolution as a 23" ACD). It is supposed to sleep when unplugged (with an external display) to conserve battery.macbook isnt going to run a 23" ACD as well as the MBP will (when working right)
do you have all of the software updates installed?
