Not powering after changing front glass
I recently changed the front glass and track pad on my MacBook Pro 13" mid 2012 (A1278). Now it won't turn on.
Retracing my steps
I used a heat gun to loosen the shattered glass and removed it.
I cleaned the glued area with a micro fiber cloth and a compressed air can and mounted the new glass.
when I tried to power it up and nothing happened. I plugged the power in and again no power. I noticed that the green light on the power plug can on for about 40 seconds and then it dimmed. I then tried a fully charged battery from my other MacBook and still no power.
I'm not sure what happened or how to figure this out. Can anyone help me with this?
Is this a good question?
