    Macbook Pro A1989 820-00850 No Power
    by rarinpear
    Hi all!

    I have a Macbook A1989 820-00850 that completely died out of the blue.

    I have used a usb tester and the computer is (not) drawing 5v 0amp.

    I have now taken the board out and there are no visual clues of components going bad.


    Can you help me diagnose the problem?...

    Philips 40PFT4009/12 bootloop (TPN149E)
    by RethoricalCheese
    Started after unplugging power cable when TV was turned on. (remote control was lost and user didn't know where power button is located)
    So my first thought is firmware corruption.

    Tried autorun.upg and upgrade_loader.pkg on 16GB FAT32 MBR formatted USB stick but neither did anything. Maybe I just don't understand how to start them.
    When USB inserted and TV plugged in, it just starts up and continues bootlooping. When USB plugged in and I hold down power button when plugging TV in, it just doesn't do anything.

    Attached boot dump (at the end it just restarts...

    by sam_sam_sam

    Which laptop battery pins are used for charging?
    by Klevjetack
    I have a laptop battery and I am curious on which of the pins are responsible for charging the battery and which ones are responsible for outputting power to your computer. Are there any websites that I can use to find this information or manuals that will tell me?

    Hello folks,

    I hope you are doing well.

    I have had a macbook Air, from 2013 with 8GB 1.7GH one day (almost 1 year ago) it had failed, so you know as a human being, I had to try to fix it, but then i caused a lot of more trouble by shorting PPDCIN_G3H with PP5V_S4RS3 by mistake, which I then fixed to a good extent (macboook was powering up three times then normal boot, into internet recovery (which was not working) but booting into ubuntu via a usb stick went halfway, etc... so after so much time spent on this logic board replacing stuff to get it to that working state,...

    Hi again all. Picked the above model up a couple of days ago. Information was that it just stopped working all of a sudden. Was from a nice house with no kids or pets and no reason to think it's suffered impact damage.

    Working my way through it. I get a flashing silver light on the front which indicates an attempt to start?? Then it turns off and doesn't attempt to reboot.

    Had the back panel off and with the plugs disconnected to the backlights, on the connectors I'm getting 63v DC on CN 6801 and 4.0v DC on all pins on CN 6802. All except the not connected ones I should...
