MacBook only charges when shut down
I have an Early 2011 MacBook Pro 13" which has developed a problem were it will only charge when shut down.
With the MacBook turned on and the MagSafe connected it intermittently switches between high and low screen brightness, the LED on the MagSafe adapter is not illuminated but sometimes flashes green, and the battery indicator states "Battery is not Charging" "Power Source:Power Adapter", although this is incorrect as the Battery is discharging.
I have the same issue with 2 different batteries fitted in the Mac.
I don't know if it is related but also one of the USB ports does not work, and the Backspace, Volume Up, Volume Down and Eject keys do not work on the keyboard.
(I can deal with alll these issues though)
Thanks for any help.
