A customer brings his MacBook Pro (15-inch, Mid 2012) in for servicing. It is not functioning
correctly and you suspect the machine has been damaged by the customer. As you inspect
for accidental damage, you should open the lid and confirm that the hinges are working
smoothly and inspect the LCD for cracks in the glass. Which of the following should you
also do? Select two.
Disassemble the SuperDrive to check for debris or dust inside.
Look for cracks, dents, or scratches on the exterior of the system.
Connect the system to external speakers to check for sound output.
Erase all of the customer’s data and reinstall OS X to test the hard drive.
Check for any unusual odors coming from the system, which might indicate spill damage.
