Hello Everyone, I received a Macbook Pro Retina Display - 13" - Early 2013. I ran an Extended AHT on it and at the the end of it reported an error of 4SNS/1/40000000:icor- 10.996. Can someone help me with this error as to what it needs to be looked into. The computer trackpad is laggy and the screen shifts from its desktop to the widgets screen. Also if left of battery power the computer shuts down on its own.
