C3800 = 25UF, 6.3V, X5R, 0402 - part value is not super critical. Let me double-check this part as the part does not look like 0402 in size from the pictures.
Ok - the part location and size match the schematics = 0402. Just looks larger than 0402 to me.
If possible, please measure the size (length x width) of this capacitor with a micrometer to confirm. To me, this part looks like 0603 or 0805 in smd size. You can always purchase a few of each size = 0402; 0603; 0805 to be safe. Schematic states 0402 in body size.

by badboyzzzI have a strange problem with my iPad Pro 12.9 4Gen / A2229. When I start the device, it stays on the Apple logo, but when I heat the back of the device with a hair dryer, the device boots, but this time there is an interesting problem. The iPad is charging, but there is no USB data on the computer. The USB charging port has been changed and the chips seem normal, but I have given it to 2 different Apple services in Latvia, but the repair could not be done. Is there anyone who can help with this? Can someone support the repair by sending only the motherboard within Europe? Thank you.

by flat-eartherThe charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.
Windows also shows ''Plugged in'' when charger is not connected.
This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.

by AimbitI purchased some broken iPads (non-charging), trying to repair something a little trickier than retro consoles... I have all the necessary tools.
A1430 - Draws 930mA consistent, screen is black with red/empty battery icon, no charging symbol.
A1403 and A1416 - Draw 930mA, wait 3 seconds, dip to 0, repeat.
A1566 - Similar to the previous issue, it draws some power for a few seconds, then resets my ammeter, and repeats. Waiting for my lightning port tester to come to check the tristar.
Seeing as these are old, and likely have been dead for ages, is a battery... -
by waterchillHey folks, I have this iPad Pro 12,9" 4Gen A2232 here with no charging issue. The main fault was a crossed pins / faulty USB charging port due a bad cable.
So I started to replace this parts:
- replaced usb-c port -> no result
- replaced battery -> no result
- replaced usb-c chip CD3217B12A -> no result
- replaced 343S00326 -> no result
- replaced 343S00327 -> no result
- replaced 343S00328 -> no result
I have no more ideas for this issue. There is no short on the whole board, and the iPad is working fine... -
