Battery connector socket popped off

Block Image

My son dropped my wife's Switch into the toilet a few years ago, and the battery had been degrading ever since. I recently ordered a battery replacement kit and went about about replacing the battery as normal - but when I went to disconnect the battery cable from the motherboard, the cable socket itself popped clean out. I'm wondering if this is the result of corrosion from when it was dunked, even though I opened it up at the time and dried it out as best I could. Is there any way to replace / re-attach the socket, or am I SOL?

Answer this question I have this problem too

Is this a good question?

@kylekissinger Just to add to the excellent answer given by my colleague @tech_ni Yup, starting to look a little crusty there. I would treat it the same way as any other water immersed device. for now you want to stop continuing to try to charge, turning it on or otherwise use your Switch.This potentially can make a bad situation worse. This may further damage your device.

The next thing to do is to clean it. Disassemble your console using [these guides] . You must remove all EMI shields of the motherboard. If you do not remove those, you might as well not do anything. After you removed those, clean the whole board, connectors and all with +90% isopropyl alcohol. Follow this guide , and even so it was written for an Apple iPhone 3G all the points are still pertinent to your device as well. While you clean your board, check for any obvious damage, like burned or missing components etc. When it is properly cleaned, replace the battery. All these steps are to avoid delayed failure caused by corrosion (creeping up on your board already). Best thing to do would be to clean it with an ultrasonic cleaner, but if you do not have access to one, this will at least help. In your case it is the perfect opportunity to either resolder the connector or replace it with a new one.

Once all this is done, reassemble your device and reevaluate. Until it is cleaned, everything will only be a guess. Let's see what the traces look like where the connector solder to. You may need to run some jumpers etc. but let's get a closer look.
