MacBook air doesn't power on. Shows no signs of life besides charge li
Tekst:
| Early 2015 11 inch macbook air |
| Macbook doesnt power on or show any signs of life besides charge light. I took it apart and saw no obvious signs of any damage. I was told that it needed a logic board replacement, but wanted to see if there is another option. |
| What I did find, is that the power button does nothing, but when I short the jumper inside the light goes from orange to green and then back to orange again after a second or 2 |
| I tried a pram and smc reset with no luck. Also tried disconnecting everything with no luck. I left it sit for a bit all unplugged with nothing either. Anybody know what might be wrong, or anything to test |
| Update: 8/9/19 Did some voltage testing on batt connector. Not sure if this is how it is supposed to be, or if this helps anyone. From what I can gather, 1 2 and 3 are negatives and 7 8 9 should be positive from the schematic, although it is switched where 7 8 9 are neg and 1 2 3 pos. But I have it looking at the connector, with the dc in on the right, going from left to right (pin 1 is far left) |
