I know that the MagSafe 1 charger works as the light illuminates when I use my older 2012 MacBook Pro and 2010 MacBook Air.

Is the light supposed to illuminate when using the adapter or is my adapter defective? I tried to clean both the MagSafe 1 plug and both sides of the adapter and the MagSafe port with isopropyl alcohol but that didn't seem to fix things.

There is no hint on Apple's site of it being a DAC also.

Thanks.

I have a Magsafe 85W with a broken T connector, and I have a Magsafe 85W with an L connector but a failing power supply.

So I want to replace the broken T connector with my other L connector.

It would be ok to join both cables in the same order, the inner cable of the T power supply, with the inner cable from the L connector, and the outside cable with the outside cable from the L connector?

Thank you!

Happened over night, worked fine yestreday.

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

I use it for my Early 2015 13" Retina MacBook Pro. The charger itself is the 60W version.

Recently I've noticed it's been shutting itself off often. As in, charge light turns off, and it stops charging the battery.

When it does this, upon noticing I unplug it, the first time I made the mistake of grabbing the charging block, (I have learned to NOT do that now as I gave myself a decent burn) whenever this happens the charging block is horrifically warm.

The first time this happened I had shrugged it off as an isolated event, as my cat had been sitting on it, and well, my cats pretty warm.

Then it happened 2 more times while having nothing covering it.

The most recent incident was about 5 minutes ago, I noticed a slight burnt smell, (I had also noticed this with the other incidents) my charger was still charging, but I unplugged it and briefly tapped the charger with my finger, it was overheating. I had likely noticed it just before it would've shut itself off.

The charger itself is in surprisingly good shape for it's age, (at least externally, I can't see the inside.) Wire is starting to turn yellow in places, and there is a small tear in the coating but the wires are intact.

I have also noticed that ONLY the block gets warm, not the cable.

My computer's battery is not the best, so I 80% I have it plugged in.

The only other charger I have right now is a Apple MagSafe 2 45W one, not entirely sure if using it would have some sort of negative effect though.

Battery temp showed as 31c before being plugged in, so it actually dropped a bit.

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.

---------------------------

Charger: 60W MBP MagSafe Adapter (A1344)

Laptop: MBP late-2011 13" A1278

Story: I plugged it into an old outlet in an old hotel in India, and I wake up to find the charger not working anywhere. Other chargers work okay and SMC reset done. CoconutBattery says the battery is okay. Culprit is the charger.

Diagnostics: I checked the primary fuse (the brown box near the AC input - apparently a "4A time-delay type fuse", and it had no continuity. With so much glue and padding and shielding everywhere, I really didn't risk probing much further. No swollen or blown capacitors.

Troubleshooting: Here's the fun part, I got some thick wire and bypassed the primary fuse by soldering it to the existing little prongs on the opposite side of the PCB. It kind of worked... I can get a green light, but it makes a buzzing noise sometimes depending on the position of the L-shaped DC laptop port.

Current status: The green light turns on. However the MBP isn't charging normally nor holding its charge. Occasionally I'll get the DC end in the some kind of position where an orange light comes but it's rare.

I attached a screenshot of iStatMenu's power stats. I don't really have a reference point, but I'm pretty sure that DC-In should be more than 0.08 amps. Though there are some intermittent spikes when charger is wiggled at the laptop-side and it buzzes. I found that by wiggling the DC charger end (which connects to the laptop), the buzzing will start and stop (kind of like when a your old earbuds don't get sound unless they're in the right position). Which is odd because that part of the charging cord was fine before and I didn't suspect any problems there, but I could be wrong. (see video and photos attached for demonstration).

Hey after some random wiggling - I have an orange light! Not sure if its actually pulling enough voltage/amps etc. though. Hard to reproduce. Yes okay I can get an orange charging light and get it to pull ~2a and charge but only when it's buzzing. Something's weird. Without the buzzing - there's not adequate charge.

i guess this can be done with a regular voltage meter with a bit of knowledge but I am looking for a specific module that can do this...... Something I can simply connect an L or a T-Type.to and get some sort of data from....

I change many power supply's cables, but it a new model. It has got yellow felt cover is soldered. I don't remember, I didn't look at it before I soldered it out. Should the soldering of the two points meet? I circled the picture. One is the black cable that goes to the magnet, and the other is the point of the copper covering.

Would appreciate your help

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