No light on charger, and no power

問題

My mac did not charge, and would not boot up when the battery was disconnected.

修理

I browsed the web and found out that there was a part called the magsafe board betweeen the charger and the other components. I followed IFixit instructions and replaced the magsafe board.

The only problem I have discovered is that my camera isn't working.

アドバイス

Use force to put the keyboard ribbon back in its socket. I struggled with this for some time.
