    Ipad 5 help please

    I'm stuck! 🤣

    IPAD came in working requiring a home button replacement, after open digitizer unscrewing battery and replacing button it is now dead, no idea why, done it a million times

    I have an iPad 5 a1822 that has no signs of life.

    I have replaced the charging port and done a diode check everything's perfect

    I have replaced the battery with new one

    I have replaced Tristar with known good.

    I have checked everywhere for shorts but can't find any.

    I have connected to the bench power supply to the battery terminals and there is no current draw at all.

    Any ideas?

      What is the exact current draw if powering by the standard lightning to USB cable?

      Suggest to flux and confirm the soldering of the charge port cable to the main logic pcb.

      What is the exact current draw if powering by the battery connector?

      Do you have a thermal camera?

      If the current draw here is low at the USB charge cable, usually a fault of the TriStar chip.

          Apple iPad Air 2 (A1566) - Seems to be power cycling, no display, new battery/Tristar
          by Aimbit
          Using an ammeter, original battery was only taking 90mA or so... then down to 0, up to 90mA, down to 0, etc, in a repeatable pattern. This iPad was very old, so first thing I did was swap the battery for a good one, and it came pre-charged. The old battery had negligible voltage.

          Now the iPad go up to about 1.5-1.6amps charge, then it drops to 0 after a few seconds... rinse/repeat as before. I tried changing the Tristar chip to see if that would help (and also my first real BGA chip!) but it seems to make no difference. Where should I look next?

          I should poke around the...

          I tried searching the forum for whether this has been uploaded already, but couldn't find them (as a collection).
          Here's a dump of a bunch of iPads, I've split into 2 archives to get under file limit

          A2197 / Ipad 7th Gen / 2019 - No Power / Low Current Draw
          by willis6732
          Hello,

          Ive been working on this ipad for a little while now. CPU reballing is a common issue needed on this model.

          I wanted to try and verify there is not a PMIC Problem before reballing the CPU.

          Powering 4.2V at the battery gives a 0-1ma Draw
          Pressing the power button it jumps to 18+ma and settle at 15ma

          Ive attached my Readings for many of the power rails.
          THis is how the columns are layed out:
          Ohms/ Diode / Voltage After power button Press / Injecting Voltage Reading



          In the second...

          Ipad 5 (2017 A1822) Need help identifying component
          by Papa Gleb
          Hello all,

          I have an ipad 5 that came in for home button repair. Issue fixed and return to the customer who then stated it also has battery/charge issues. The battery seemed fine however the ipad would acknowledge the charger every other time. The port looked fine but considering that it would work than not, I decided to change the port. Port changed and yet it draws zero amps. Removed the shield and found this burned component. Tried to find a board view but seems like the ipad 5 is the only ipad for which board views don't exist.

          Yes I should have definitely done...

          IPAD 6 (2018) A1893 No power
          by SolderNewbie
          Hi all,
          I'm trying to fix an IPAD 6, 2018, A1893 WIFI.
          It does not turn on and does not enter recovery or dfu mode.

          History
          The device was working before, but did intermittently reset.
          I gathered two panic logs:
          "panicString" : "Attempting to forcibly halt cpu 0\ncpu 0 failed to halt with error -5: halt not supported for this configuration
          "panicString" : "panic(cpu 0 caller 0xfffffff020e14724): nvme: "AppleEmbeddedNVMeController. Controller fatal bit set. Write.
