apple macbook pro a1286 first come out date

( so, yes, I borrowed my brothers perfectly good macbook, same model, and blew the fuse - he was very grateful ) I'm pretty sure the target board's WLED is good too, I've got readings that agree with posted measurements indicating all OK. Is it possible for a faulty Magsafe to cause the 2A fuse to blow? I've replaced the fuse twice now, both times the the resistance is 0 and connections good, then when I assemble the board with magsafe and apply power, no backlight - when I test the fuse again it is blown.Īny links or advice on how to check if the magsafe connector is functioning correctly?Įdit: sorry, should have mentioned - this has happened on 2 different boards (both 820-2533-B), one of which I know the WLED is good and was working fine before I tried it with the macbook I'm trying to repair. Except, on an Apple board(or any modern board), don't assume something is a fuse, capacitor, or resistor based on the color of the head of the device. Sorry I didn't have anything useful to contribute. The people who don't care will likely be onto their next job by the time their work blows up in someone's face, and it won't be their problem. Patch it up with the least amount of work, skills, or equipment necessary, and be on their way. People who care if someone sees what they did 30 years later. It's hard to find people who care about basic workmanship. Now, I look for the value of the fuse, and replace it with a proper fuse. Not that this is any less ghetto than putting a strand of ultra high gauge wire between the pads. I couldn't bring myself to solder over a fuse.

Soldering over the fuse seemed too ghetto, the ball would have to be large and heavy to go over the fuse.

I lacked the equipment to do good SMD rework, the best I could do was solder a jumper after removing the old fuse. I really thought this was limited to my live sound experience during my teenage years where the FOH guy would wrap the fuses of the amplifiers with tin foil from his lunch sandwich if they blew mid show, but this crap happens all the way up the ladder.ģ and a half years ago before I had a clue I'd use a featherweight wire, something even skinnier than a strand of wire in an IDE cable, after removing the fuse. Some of the biggest reverse logistics providers in the country that large shops send their customer's boards to do this as common practice. If it wouldn't lose me a lot of LCD wholesale business, I'd love to tell you how many professional shops that claim to do board level repair solder over the fuse.
