Member: 2598526 Status: Offline Thanks Meter: 52 | I’ve had this happen on every single one I’ve gotten and I’m led to believe it’s the main power ic. But they’re an expensive part so I’m just going to piss all over these stupid iPads |

Member: 48755 Status: Offline Thanks Meter: 30 | that's the U2 issue i got few like that, replacing the U2 is not easy as it's too close to nand. so put kapton tape and even a small aluminium radiator used for microcotrollers or cpu, and try to clean all that ****ty glue under the chip, then try to clean all the old solder and try again some chinese refurbished U2 IC's, and especially the 1610U1 IC's are bad. i got 75% failure on one delivery from Aliexpress once .. |

Member: 48755 Status: Offline Thanks Meter: 30 | i fixed one like that recently. it was laying in my shop for almost a year after i lost hope to fix it because like you, i tried many different U2 chips. i just tried a new U2 IC, and got it to work as it should. no draining, no charging issues .. |

Member: 1732818 Status: Offline Thanks Meter: 532 | I had the same problem. Ipad Air not charging when powered on. 0.02a Not even charging symbol. But will charge when powered off. I got 5v on caps from usb to Tristar. So I changed Tristar with 1610A3.. didnt help. Then i took a 1610A1.. didnt help. Other battery didnt help. In my case the solution was to change the docking flex. After that the ipad was chagring pefectly. So dont get fooled if you have 5v on the caps neer your Tristar. Your docking flex can still be defect! |
