Is there any way to fix without switching logic board? Im especially interested, because i bought a 8bugs replacement cable for my original cable but using your code to read out the adress I end up getting weird output instead of a useful adress containing all the nesesarry informations best regards Leon hi, I purchased a used 60 magsafe 1 power supply and I opened it. I've a new 60w MagSafe I got from the guy who fixes my laptop. Re-installing the old battery shows the same symptoms. I opened up an other one too this came from a suspicious store and I have to replace the magsafe cord anyway This looks more similar to yours, this one made by Delta. The problem having been, as so many other people have found, that some of the pogo-pin springs were no longer strong enough to push all 5 pins out through that thin white plastic block. Lots of in-depth info here, but haven't been able to apply it successfully.Next
All information comes from a free public manufacturer database. First, there's the part that features the two prongs that fit into electrical sockets. Use of these names, logos, and brands does not imply endorsement. I didn't disassemble the transformer, but I expect it also lacks the necessary insulation. Do upvote interesting questions and helpful answers. However, there may be more » » items available. New battery still no charging.
If you are running a beta or developer preview, head over to. What information you can get from Serial Number Lookup Function? Ops un hooked it and rushed it out side ,,Still determined i thought of wiring to the board for the batt and , Then was trying to find the pin-out for mac side and didn't understand the the data sense center if it was neg or pos pulsing or needed a resistor. After exactly one second, the charger switches to full voltage 14. The Magsafe connector introduced by Apple in 2006 is very convenient. I would be thankful for any help on the issue.
Most the time I'm running my mac from a small dc-dc booster from solar battery bank. A real Apple charger is packed full of complex circuitry, while this charger had a fairly low density board that implemented a simple flyback switching power supply. Check the underside of your adaptor to see if it is affected by the recall. The switching transistor sends pulses into the flyback transformer center , which produces the low voltage output left. Update: a clever reader identified the chip as the. The chip uses the , which is a clever system for connecting low-speed devices through a single wire plus ground. I tried covering the middle 'adaptor sense' pin with a sticky piece of paper post-it note clip the light has actually gone out it's a miracle.Next
There is no data communication via the adapter sense pin with the charger unit itself. If the system is not able to detect your model, please submit any information you have on it, and we'll add it to our database. That charger with the flashing green doesn't charge the MacBook pro at all; if I connect a different charger I get the normal first orange and finally green indications. Normal legal limitations like remoteness of damage can apply but, those aside, potential liability is uncapped. It has most control circuitry I've seen. It snaps on magnetically and disconnects if you pull on it. For a Serial Number lookup, be sure to enter the entire serial number.Next
Could you guys help me identify if it is a fake or not? Not really, but hopefully you found it interesting. Does a working Magsafe output any voltage with no load connected? I figured once you've removed the casing and have the flat cells in a stack, its quite smallish and would be good for a robot project. I'm on a power adaptor crash course at the moment. I've went to official Polish Apple service and there they couldn't say if the adapter genuine or not. At least it gives the same serial number all the time. I wish someone had done similar teardown of mbp preunibody batteries, the genuine one, and the fake one. Peter Moon is a technology lawyer with Cooper Mills.Next
The Arduino program cycles through the three colors and off, as you can see from the pictures above. More filtering inside the charger reduces these voltage spikes, but would cost more. The devices actually consist of two parts. The immediate issue is to audit, and replace any potentially dangerous Apple duckhead. Apple's website advises that in very rare cases, the two prong wall plugs designed for continental Europe, Australia, New Zealand, Korea, Argentina and Brazil can break and create a shock hazard. Should I try putting more solder onto the pins if I can get them out again and pushing them down with heat to make them stick? According to the lawsuit, once Apple alerted Amazon to the fake chargers supplied by Mobile Star, the company turned over its entire inventory. Seems there are at least 3 kinds now.Next
It still isn't clear to us whether notebooks are affected. Procedure To clean the Mac mini case, do the following: 1. Don't try this at home Warning: I recommend you don't try any of these experiments. With your information and the circuit diagram of the Macbook we will keep on working. I then plugged in my formal Apple power adapter and nothing either! The counterfeit power supply has all the same safety indications as a real power supply.Next
Place the new thermal pad on the bottom housing as shown. I'm puzzled as to why counterfeit chargers never manage to have sufficient clearance distances. Only the Apple adapters detect the load and only come on once they see the load provided by a 68k resistor in the MacBook. The Mac and charger both have various protection mechanisms, but they won't take care of everything. Here is a guy who looked into the communication signal info in Japanese. About the Author Based in California, James Wright has been writing since 1998. Service allows you to get all information about all Apple devices.Next
The switching power supply operates at about 60 kilohertz, producing large voltage spikes in the output. Thanks for all the valuable info - just one thing missing for me, how does the charger detect and respond to disconnect? Also note that the middle adapter sense pin is much smaller than the pins, unlike the Magsafe 2. I started to test the charger on an other mac where it worked fine leds shining bright and suspected the small magsafe board inside the mac. Unplug all cables from the computer. For a list of subjects inappropriate for , see Guideline 2 above. A new thermal pad is included with the logic board and the bottom housing, and the pads can be ordered separately as a kit part number 922-6749. Should there be a direct connection between the spring-loaded pins and the two wires that go to the brick?.Next
