How can I determine why my MacBook will not boot?
Based on my intermediate knowledge, I believe it is either the logic board or the topcase that is malfunctioning. Would anyone be able to help me determine how to pinpoint the problem piece of hardware?
EDIT: Sorry, I forgot to mention that there is no response at all when I try to power up. No chime, the screen doesn't turn on, nor does the white LED. Also, I've tried resetting the SMC.
Thanks in advance,
Nathan
