Keeps restarting after battery replacement
A customer has just brought an iPad 3 4G into me a company had replaced the screen for him.
The screen had come away & the LCD was pushed out also the iPad would no longer power on.
He did take it back to the company that replaced the screen but they basically said there was nothing they could do so he approached me.
When i looked at it what had happened was the battery all 3 cells had expanded which was causing the LCD up & it had forced the screen off.
The customer said there was what looked like an oily residue under the screen before the screen came off.
I inspected it as i suspected the battery had leaked but i could not fine any signs of leakage.
I did notice who had replaced the screen not only used the adhesive that comes with the screens but they also used LOCA adhesive also not sure if this has any effect i was always told never use any other adhesive other than the pre cut strips provided.
I replaced the battery & the iPad started up OK.
I noticed when i was putting it back together the motherboard where it joins just above the 2 parallel screws it had come apart normally this stays together so not sure if this could be anything to do with the issue?
After reassembling & starting up there was less than 20% battery in it it all stayed on no problems.
I put it onto charge & left it overnight on a wall charger not my Mac. it had only charged up to 58% & it was starting up for a few minutes then it restarts i powered it off & it then charged up to 100%.
I took it off charge but it now powers on for about 4 to 5 minutes then restarts.
Has anyone had this issue before if so how did you resolve it?
Could this be a fault with the new battery i only have the one battery so don't have another to test it.
Or any ideas or suggestions would be greatly appreciated
With regards to the motherboard coming apart i'm uploading an image.
I'm guessing this is going to be a big problem?
Ist dies eine gute Frage?
Thank you for your suggestions guys.
I have tried 2 new batteries in the iPad both with the same result it just keeps restarting.
The motherboard is in the original housing it came with so it can't be that.
I didn't think that module at the top would be the cause of the issue but i needed to ask
its puzzling that when the battery gets down to 20% or less it doesn't keep restarting over & over.
It may be possible that the original battery had leaked i may try cleaning with alcohol.
