What do I do my oculus wont turn on at all!

@romeo1234567891 you got a bit of a problem here. As you probably know water and electricity do not mix. For now I would treat it the same way as as I treat all liquid immersed devices.

You must stop continuing to try to charge, sync or otherwise use your headset. This potentially can make a bad situation worse.This may further damage your headset. The next thing to do is to clean it.

The very first step I would take is to disassemble your Quest 2. Use these guides Meta Quest 2 to help you disassemble it. Take a close look at all components and connectors to assess the damage. Look for corrosion, evaluate the pins in the connectors etc, (it'll appear black this early in time). Take a look at all connectors as well as cable ends. You will have to remove the EMI shields of the motherboard. If you do not remove the shields, you are not cleaning the board. Once you got the gross contamination cleaned, use +90% isopropyl alcohol and clean your parts some more. For a proper cleaning, use this guide. It was written for an Apple iPhone 3G but it is still pertinent to your device as well. I can not stress the importance of a good cleaning enough, so do it over and over while replacing the alcohol after each cleaning. Do not use compressed air for the cleaning since that can drive liquid as well as corrosion particles into areas that will cause trouble later on.

The importance here is the cleaning. It would of course be best to get it professionally cleaned with an ultrasonic cleaner, but if you do not have access to one, this will at least help. Do not forget to replace the battery. This is a must and not an option. It will fail if you do not take care of it now. After that, reassemble your headset and re-evaluate. For as long as you have not cleaned your board and replaced the battery, everything is just a guess. Keep in mind that water damage is the hardest to troubleshoot and to repair. It does not matter if is was exposed for 2 seconds or 2 hours, what matters is where the water (particulates) did the damage. As for your mother, I doubt she will end you but I think it's time for you to inform her of the mishap. It's the right thing to do!
