    820-4924-A Water damage, PPBUS_G3H fluctuate

    I bought a soldering iron and a hot air station to try and put wires in place of R7152. I ended up screwing up U7100 with the soldering iron and couldn't get the pins to connect to the board again and then I fucked up the pads on R7152 as well. The hot air station couldn't even get a resistor of...

    Great. Thank you for all you help. I guess I can try to put wires there if it will work. Is it magnet wire that I should use or could I use any copper wire for this since it only a replacement for a component?

    Thanks. I just ordered a donor board. Will replacing these components fix the fluctuating voltage when the battery is not connected?

    820-4924-A Water damage, PPBUS_G3H fluctuate

    R7152 2.4 ohm R7152 5.8 Kohm So I'm guessing R7152 is shorted to ground/faulty here? When trying to measure R7152 I just touched C7150 and it broke of. So I will need to get replacements for at least R7152 and C7150 Is it possible to order these parts online somewhere like Mouser or do I have...

    Ah thanks. I can't find R7051 and R7052 in boardview though. I can find R7050 and that is exactly where the corrosion happened. I'm at work at the moment but I will check this when I get home tonight.

    820-4924-A Water damage, PPBUS_G3H fluctuate

    If I do this correctly I get 5.2 Kohms on 17/18 and on 27/28 I get 20 ohms I measured 17/18 on C7150 and 27/28 on C7120 if that is correct. I plugged in the mouse and it lights up both when power+battery is connected and also lights up when only power or only battery connected. When only...

    820-4924-A Water damage, PPBUS_G3H fluctuate

    No Title Is the ISL the U7100 or U7200? If I look in the schematics I only find these two with the name ISL that have up to 28 pins. And by 17/18 and 27/28 do you mean resistance between 17 and 18 or 17 and 27? My probes on my multimeter are two thick so can't seem to get an accurate reading...

    I have a Macbook Pro 13" Retina 2015 (A1502) with a 820-4924-A board. It got water damage and I got if for free from work to play around with. I've watched many of Louises videos and I'm very interested to learn board repair as a hobby. I get a green light (turns orange after a couple seconds)...
