Identification of Logic board part (Picture attached)
I would really appreciate help identifying the part in the attached picture (Square component with "4.7 UH 1015BE" inscribed on it).
Reasons and history below:
Symptoms: Computer will not power on. When Magsafe charger plugged in, light on L shaped connector is initially green, then shortly starts blinking between orange and green (still no power to notebook).
Suspected issue: Power circuit issue caused either by corrosion, a voltage fluctuation, or both combined.
Description:Recently the Macbook Pro of a friend suddenly shut off, and refused to start up again. The Apple store quoted an financially un-viable replacement of the logic board as the only solution, as it would be more logical to purchase a new mac. However they did indicate that it would be a power related issue (most likely a surge in voltage I presume).
I have successfully disassembled the mag safe charger (which does not seem to have any issue from an initial inspection) and then went on to remove the DC-in board and the logic board. The only issue I would spot was some corrosion on the component shown in the picture (to surface of the logic board). I want to find out the component, in order to determine whether this is the issue.
Further images- (sorry, bad quality. Phone camera!:( )
Is this a good question?
