Hi everyone, looking for some help. I have a mid-2009 MBP 13" running ML. For a couple of months its been connected to a 27"cinema display (non TB) and working fine. I disconnected it today and find out that it will not charge (NO light on charger, amber or green) with a normal mBP charger, of any variety. When I connect it back to the display, it charges fine. I have reset the NVRAM and the SMC. Any other ideas?
