Hello,
Just bought a dead MacBook a1304 (emc 2334) that has cracked screen no power and swollen battery. The battery is only swollen a little, but I am going to replace it. If it is still dead, where would I test for voltages like pp5v0, pp1v8, etc. and does anyone have a schematic I could use?
Ist dies eine gute Frage?

Honestly, I would not recommend putting the time in to fix this model, just resell it on eBay as is. For a start, the price of a new LCD and battery will set you back, and if you replace the screen, you might as well replace the hinges whilst open (these usually break on this model).
The main reason I would recommend against fixing this, is since this model is notorious for developing CPU, GPU and RAM (which is soldered on this) issues. Chances are, if you get this working, it will beep at you, or will develop this fault shortly after being sold.
I have a regular who buys broken MacBooks from eBay and sends them my way to repair. Last year, I told him I am not repairing these models anymore, since I would get them working to find a CPU/GPU/RAM issue, which was a waste of time, or he would get it returned from his customer within 2 months with this fault and have to refund them.
If for some reason you do decide to repair this, find the board number on the logic board and Google "820-XXXX schematics", which will give you some results. I would recommend taking my advice though :)
War diese Antwort hilfreich?
Thanks, this was a little project and was the cheapest one on eBay except the a1181. Was only like 40$ and how would I find the board number?
@gigabit87898 it will be somewhere on the logic board, on some models it is under tape, the location changes from model to model.
I don't know whether you get MacBooks from customers to repair, but if you do and you come across an issue you can't fix, offer to buy it from the customer. I would recommend staying away from eBay, people bid way too much for broken MacBooks, and most of them have had repairs attempted before, meaning they likely have CPU/GPU/SMC issues, i.e. will be a nightmare.
I do this, if a customer wants to sell it to me, great. If not, oh well. I bought a 2015 13" Macbook Pro Retina from a customer back in April for £125 which wasn't reading the SSD (board issue), managed to fix this recently by replacing a bad resistor for SSD_RESET_L, and now I have something I can sell on. If I had bought this from eBay at the time, it would have easily cost over £400, and would have probably been messed with.
Just my 2 cents ;)
@reecee good point, they showed a pic of inside it and it looks fine. I should ask around my school and see if anybody has broken stuff, usually there a lot of things that break in my school.
@gigabit87898 if the logic board looks fine, that is a bad sign usually, since either liquid damage has cleaned (so you lose all visual aids), or it's something more serious.
Yes, contact people you know, selling something out of eBay means no fees and usually less hassle for the seller. This is definitely the best way to buy broken electronics, since eBay is a huge marketplace full of people wanting to buy a specific product, and therefore pushing the price up by bidding.
@reecee is there a LCI on this MacBook so I can check?
