So my MacBook Pro decided not to turn on this morning; well, the light turns on, it just shows a blank screen (no start up chime comes on, doesn't even boot into the OS). The Genius said the issue isn't the NVIDIA card as the computer doesn't even fully boot on. So my MacBook Pro is 2 years out of warranty, and they decided to give me a new Logic Board free of charge. This is some great customer service. Anyways, what to expect with Logic Board replacements? Is it more likely that the Logic Board won't fail again now? Or is it more likely that this will turn into a vicious cycle of repairing? Thanks.
