iPad pro keeps restarting
we will be working on an ipad pro 10.5 inches
The ipad would reboot every few minutes, so
we thought it was a software problem.
So we did a software update
It didn’t help.
The screen crashed the client did a software update
update or restore, which did not solve the
problem with the reboot, and the customer replaced the
the actual screen.
This is the right solution to see if
That would solve the problem, but it didn’t solve the problem.
What I want to do is a quick physical
inspection of the board to see if there is anything obvious
Since this tablet was suffering from a drip. We
Look for possibly broken coil parts.
I’ve seen this happen with coils and
A bell has broken and I’ve seen it more than once when a

we can still see the edge of the component here.
It’s not the soldering that’s broken, it’s the actual component that’s more of a

that we have, and we’re going to use
the coil with this one and put it on.
The first thing I want to do is distract.
These broken pieces and let’s also remove this
we’re going to add some solder.
What I want to do now is grab the
component from the donor board.
I have a donor board right here.
Let’s use hot air and solder that component
onto the client board.
All that’s left to do is assemble it and test it.
So, assembled the board and said this
The tablet is still rebooting, I’m going to
take another look at the board, just
to see if there’s anything else that we
might have missed.
Quickly saw that we are missing a

Now I want to continue the physical inspection.
The actual legs, pads, and solder
are very solid, but the component itself

Not as strong.
So if you hit it, you could lose the coil or
the bell can become loose or broken.
At this point, we haven’t seen the bell inside the
tablet, but that’s probably because the

most likely fell out without the customer’s attention
Without noticing that it’s a tiny component.
Examination of the IPAD
So I’m doing a more thorough physical inspection of the
board to see if we have
So far everything looks clean.
I want to check these calls, I’m going to
check every single coil
just to make sure we don’t have
This is the one we swapped.
The three missing coils on the same board.
This shows how important the physical
Okay, I won’t be able to place my
tweezers on this section of the board, so
let’s use our regular
Let’s start by preparing the overlays, just
Now we’re going to take the coil from the
the donor board, let me make sure
that we’re taking the right coil.
It’s on the right side of this chip and here it is.
Okay, that’s one. And let’s do the other

And let’s solder it to the client

It will work without rebooting great I never got to the
