MagSafe charger LED turns from Green to AmberReset SMC, MagSafe LED change to Green and back to AmberPress power button for 10 seconds and press again still will not turn onOpen the back cover, disconnect the battery and still will not turn onCharged over night, the MagSafe LED stays Amber! Is it a logic board issue? Thanks for any helps.
Let’s give this a try. Disconnect the MagSafe as well as any other cord from the system. Then open the system and disconnect the battery again, this time press the power button a good 15 secs. Then plug in the MagSafe cord in the system should spontaneously start. Did it? If it did then the issue is your battery, if not then your logic board has issues.
