Charger light green but macbook pro doesnt power on

As of yesterday my Macbook Pro was fine, the battery died cause I was using it. So I plugged it in as always, and the charger led turned green to red so I thought its because the battery is completely drained. I let it be like that overnight, the LED on the charger turned green as you can see in the pic indicating the battery is charged. However its not powering on. All these time I had an older MacOS version but updated the OS two days ago to the latest. I wonder that has something to do with it? I know the charger cable looks bad and this is because I tore it more to see the cable, its only the shield that broke partially so as an Electrical Engineer I wouldn't think that would be the cause of a problem. I took my multimeter at work so cant check the voltage though. Tried the usual remedies like reseting the power management unit, (press and hold alt, control, shift and power ) to no avail. At this point need sone help from the experts.

Hi,

this is just a suggestion, but I think it may solve the problem. Considering you know electronics, and as and engineer you did everything right. I am also a engineer like you, so I feel secure to propose you this:

If you have the right tools, and by the picture you will need because this model has an internal battery.


Disconnect the charger cable.

Open it by removing the botton alumimium cover, and disconnect the battery internally (just near the battery it has a retangular connector easy to pull)

Let the battery disconnected inside it

put back the botton aluminium cover

close the lid

plug the charger

open the lid


I am pretty sure it will power on


(Did you remember how many cycles had you battery before the upgrade?)


I will folow this thread to be notified about your reply, and I am pretty sure it will work.. than we can talk about it [I have already seen it similar]

:)
