    A1278 820-3115B U7400 warming up

    Hi,
    I'm repairing an A1278 820-3115B and I notice that the U7400 is heating up...
    Already replaced the IC and transistors and the IC keeps heating up.
    Can anyone help to solve it?
    Thank in advance

    The best way to drive a heating element?
    by EasyGoing1
    I've got this circuit that I've been playing with on a breadboard. I'm not happy with it mainly because the MOSFET gets too hot and generally controlling the temp of the heating element with the Arduino has proven to be a little more cumbersome than I would like.

    What I would like to know, is what is the best way to set up a circuit like this? The heating element is just a PCB and its going to be mounted under a 3D-printed enclosure that a lizard will use to warm his belly.

    This is the general setup that I have now.



    This is what the...

    MacBook Pro A1707 Motherboard Diagnostic Help – CD3215 heating and Fluctuating Rails
    by Cemal Odabasioglu
    Hello everyone,

    I'm currently diagnosing a MacBook Pro A1707 motherboard that does not power on. I've gathered some data but am stuck and need expert advice.
    Note that i'm a beginner in electronics and i'm trying to learn while trying to repair this macbook that my work gave me. I'm really curious and love understanding how thing works and i already learned so much.

    Only one usb c port is taking 20v and have 12.5v on PPBUS_G3H. when trying other ports, 2 are not going to 20v and one is going to 20v but the CD3215 is getting really hot.

    Observations...

    MacBook A1278 (3115) No PPBUS_G3H Issue
    by pcbmaniac
    Subject: Help Needed: MacBook A1278 (3115) No PPBUS_G3H Issue

    Hello everyone,

    I'm working on a MacBook A1278 with the 3115 logic board and facing an issue with no PPBUS_G3H voltage. Here's what I've checked so far:
    1. U7000 Measurements:
      • Pin 3 has 0V, even though R7012 shows 16.5V from PPDCIN_S5_CHGR.
    2. Resistors:
      • I measured R7010 and R7011 with one leg disconnected, and both tested OK.

    Based on these findings, I believe U7000 needs to be replaced. However, I have a related question:
    • If I also decide to replace the SMC, do I need to order it pre-programmed,

    No display a1278 820-3115-B
    by dclass-pro
    Hi guys, I have this macbook a1278 which doesn't have any image on the display, but when I turn it on I hear the chime.
    I found the L9008 choke open and reset it.
    When I turn on the macbook I have about 3v on pins 3 and 4 of the display so everything is ok but I still don't have the image.
    On the backligt pin 21 and 22 I have 0v but the fuses are all ok.
    What can I check?
    I tried another display from a macbook a1278 but from the previous year and it still doesn't work.​
