Re: Teardown: Inside Apple's iPad Air
Slightly concerned at the batteries being used as a heatsink.

Introduction:
Hello everyone, this topic is more of a knowledge sharing and look inside type of post, but for someone working on this model of display it might be useful. Recently I bought Acer Nitro XV273 XB MIIPRZX with busted electronic, but screen was intact, price was incredibly low, so I took a gamble and bought the unit and try to fix it. As I dug inside, I found out that my motherboard was not responding, although all voltages seemed fine.

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.

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,...
