Happened over night, worked fine yestreday.

No green light on the adapter plug, only blinking between green and orange. what does that mean?

I can't figure out what is to blame here; is it the connector from the cable at fault, or is it the connector inside the laptop, or the battery?

Also now, the connector only charges the battery if I fiddle with its position a bit.

Any input into the matter would be much appreciated:

Thank you!

oh and does anyone know how I can safely dismantle the MagSafe connector? I'd like to check the wiring, before buying a new charger.

I've tried plugging my iPhone, iPod and iPad into this adapter, but none of them have acknowledged being plugged in at all.

I'd sadly left this too late so it's out of warranty now.

As a bit of experience, I was thinking about opening the adapter myself and trying to get it working.

So I was wondering if anyone else has actually done this before and if there is a best way of going about it?

Failing that, I can easily take it to an eWaste disposal facility.

Thanks very much!

You would think there would be some type of testing software.

(because all my work friends uses new MS2 gear, but i use older MS1 MBP.)

so anyway, i heard MS1's output voltage is ~16.4v(maybe max 18v?), but MS2 is ~20v.

i tried uses not-their-own power adapter of other things, 10~15% of over voltage is not a problem so far. but this time is over 20% difference. i'm not sure about working well this time too.

assume i can make magnet 5 pin connector thingy, could i use 20v pin to pin? should i use a regulator like 7818? or couple of diodes?

I am not sure whether it is a special filling paste or something (capacitor?) leaked. I was not able to find any obvious sorts of leakage.

recently I repaired my magsafe adapter because the wire to the end of the power adapter got broken. I repaired it by opening the case and rewired it. My the wiring was it bit loosely and the connection was broken again. Now I wanted to rewire it but, I don't remember which wires belong together.

Here you can see a photo of the adapter. Which of these (the left or the right) belongs to the inner and outer wire of the cable?

Thanks!

Connected it like you said and checked it with a voltmeter. All works fine :)

At first I though its my pc problem, did SMC reset but still nothing. Tried with my girlfriend pc, its the same. Its not charging at all only holds the power.

Does anyone got the same problem and what should I do with charger?

I have a typically frayed magsafe charger. It frayed at the end and became useless so I replaced it. Since I have been getting better with a soldiering iron, I deciede to take the razor knife and cut into the plastic part to open it up and see if I could Frankenstien it back together.

Guess what? It worked!!

You've heard "if it ain't broke, dont fix it." Yeah, well I decided not to follow that advice because I wanted to make it look pretty.

Murphy's law kicked in and it won't work any more.

Which wire goes on which soldiering point of the tiny PCB under the plastic cover? One goes opposite the chip, and one goes other end but I am unsure of myself since I messed with it too much. I de-soldered everything and I am starting with clean wire from the brick.

There is the inside wire and the outside wire and I need to know where each one goes.

Or did I fry the PCB or chip or whatever by heating too much?

Thanks in advance for the responces.

Frank

Would appreciate your help

@geirandersen I set a multimeter at the setting (see pic) and the it showed 3.1

Specifically I would like to use my old MacBook Pro 85W MagSafe2 power adapter from a MPB Retina that was stolen from me as a backup charger for my new MBP 16-inch.

There is even an adapter that does this (ELECJET AnyWatt), but it is not compatible with the MBP 16-inch.

Thanks in advance.

Its adapter suddenly stopped doing half of the work: it can maintain the battery at its percentage, but not increase its charge.

The OS icon says "Battery is not charging", with a lightning logo. The LED is off.

The same Macbook with a different adapter works perfectly. The same adapter on another Macbook displays the same behavior.

Thus it seems pretty clear that this is specific to the adapter.

Any idea what is wrong and how to fix it ?

Thanks in advance

SOLUTION : I replaced the cable and now it's working
