    iPad Gen 3 - Plugged in, continuously beeps as though disconnecting/reconnecting

    The actual port is clean, and it is taking a consistent 930 mA, no dips.

    Just did a battery replacement, the iPad did not work before either -- plugging in previously did a charging loop but went up to 930mA and down to 0, cycling, but it wasn't beeping at all. That battery is VERY dead, measured something like 24mV or something. So perhaps my replacement battery just has enough charge to make the beep, and the actual problem persists. Could this be a PMIC issue? It is not a Tristar on these but rather an Apple branded IC I believe.

    Not that I suspect this matters, but I did tear the WiFi flex antenna when opening it.

    Thanks

    Scan with a thermal camera to see if anyone is glowing from heat. A fixed current is often a shorted part. Check Alex’s YouTube videos on iPad repair.

      Thank you sir, I will give that a try, there is definitely a hot spot underneath some of the shielding, I’ll have to remove it and check!

        Apple iPad Pro 3rd Generation 12.9" (A1876) No Power/Charge When Screen Is Connected
        by grimacelord
        Hello.

        Working on an Apple iPad Pro 3rd Generation 12.9" that has a weird issue. When the display is NOT connected, the iPad will charge and power on normally. I know it's on because I can hear notification sounds and the charging notification sound.

        If I connect a brand new display to the logic board, the iPad will not turn on at all. When I connect the iPad to an 18W wall charger and a USB-C ammeter, I can see that the iPad is attempting to charge, but constantly "resets" after just a moment or two.

        For example, when I connect the iPad to...

        iPad Air A1475 Boot loops after replacing battery
        by trepachka
        This iPad was working fine except the battery was not holding charge for more than 40 minutes. I replaced it with a new battery. I haven't glued the battery yet, just inserted it into the slot and held it with battery screw.

        The iPad was powered on with the new battery and I am getting white screen with Apple logo for about 10 seconds, then the screen turns dark. It then cycles like this forever.

        I know the battery is working because the iPad continues to boot loop without the charger until it depletes to 0% and the message displays I need to plug in the charger.

        ipad pro 9.7" blew a SMD component while replacing the screen 🤦‍♂️
        by ipatch
        i have an ipad pro 9.7" (1st gen) A1674 where i replaced the screen, but never attached the screen to the frame/chassis (glued down) due to the ipad being previously dropped so the new screen would never fit in the frame properly. so i need flex/bend the chassis to eventually fix the new screen in properly. so i temporarily just applied blue tape around the edges of the screen to keep it in place. when watching videos with the ipad the screen started flicker, so i though maybe the new quasi cheap amz screen i purchased was going out. so i disconnected then reconnected with power still on,...
