Why does the long version of the power adapter turn the MacBook on?

This question is about the black 2006 MacBook. The power adapter plug that flips out had bent prongs. I don't know how the prongs got bent. I wondered if the brick that plugs in was so big and heavy that the prongs were falling out of the electrical outlet. When plugged in, there were sparks. So the plug was recycled. Then, I had to use the long cord version of the power adapter. I would plug in the power adapter, then attach the magnetic plug to the MacBook. That made the MacBook turn on without me pressing the power button.


Does anybody know why this would happen? Thank you in advance.

Depending on the underlying factor in this issue, you may have to see if

a reset of 'system management controller' could have positive effect here.

A companion reset that seems to affect other things within Intel-macs

and older PPC pre-Intel models, goes by the name(s) NVRAM or PRAM

reset. Uses a four keys-held down from power-off, then let Mac restart..

it may Chime two/three times; and let go of all those keys. (Each reset

has its own cycle. Restart with further 'troubleshoot efforts' as needed.)

And there is another magic thing to attempt, start in Safe mode; while

there you could try Disk Utility, check disk permissions etc. Then restart

normally; without the Shift key held (which initially starts Mac to Safe.)


Expect this Safe mode effort to take at least 20 minutes; it does some

repair stuff during what seems like idle-time; but it's working then.

These may or should be of use to correct errant behaviors in your Mac.

To get & try a different known-good MagSafe power adapter is advised.
