My MacBook MagSafe charger is blinking orange—Reopening as new topic to give my workaround
I let my MacBook battery go so flat that the Mac wouldn’t boot. So, I plugged in the mag connector and got the blinking amber and no boot. It didn’t seem to be able to resolve itself.
Then it hit me that I hit this issue before, and it took me a while to remember that I solved the no-boot by plugging power in with a C type plug.
Ah! That trick worked again! So once the display showed the batter icon, I could then go immediately back to the Mag Plug. It shortly had 1% and booted.
So, that may be your best first effort to get the MagSafe plug and laptop to fall in love again. The C power plug seems to reset that fault and then it works fine as long as it keeps a charge.
