Fan spins, but will not power up.
I received a White Unibody MacBook (A1342), and it is not powering on. The MagSafe adapter does not illuminate on plugin, but every third or fourth time I plug it in, the fan will spin up really loud until I unplug the MagSafe again. However, there is no response to pressing the power button. First I thought the issue was a bad MagSafe board - so I replaced it - same behavior as before. My next instinct would be to replace the logic board, but thought I would ask the question here before doing so.
In case the MagSafe adapter itself is at fault, I've ordered another which is on it's way.
The RAM slots are populated with 4 GB of compatible RAM.
I've followed countless guides on how to reset the SMC and PRAM, all to no avail.
Not sure what to do next.
Thanks in advance for any help you may provide!
