It took me a while to work up the courage to take this project on….after I’d received the part from eBay. I was concerned about finding a way to get my daughter’s photos and documents retrieved before taking it on. My dilemma was that there didn’t seem to be a way to charge the battery, which only had about 5% left. I used a 276gb flash drive to transfer the essential stuff using the remaining battery life. Then I took the project on. For a while, I still couldn’t get the bright green or amber light to come on, but just left the laptop plugged in with the dimmest green light showing on the magsafe charger. After a few days, the battery charged up (almost like a slow trickle charge). I fiddled with resetting few things, per several suggestions, to no avail. Today, however, out of a clear blue sky, I plugged the charger into the magsafe port and it turned green, then amber for the first time, and started charging pretty fast. It seems a bit finicky about how it rests in the socket. Go for it!
This one is really delicate, as pointed out. Be careful if using the pointed end of a spudger NOT to dig down and under ….there’s a layer of plastic-y insulation that can be torn. I accidentally gored it with the pointy end of a spudger and it was slightly ripped. Fortunately, I was able to press it down and there was no problem when the cable was reinserted.
