If water got in my xbox series s and i got it all out and dried the inside of it,would it...

Depends on how much. Water contains impurities, even if your console starts working, there is no guarantee it won't still fail later.

Hi there,

I'm afraid there is only one way to find out and that is by turning it on when it is dry

Some of the people replying have not read your description.. Fingernail polish is different from other liquids because it will harden. Nail polish is typically non-conductive so if it got inside your Xbox, it should not short anything once it is dried up,
unlike water for example. My best advice would be to make sure it is completely dry before powering it back on, if it got inside the Xbox. If it doesn't work properly, there is probably nothing that you would be able to do since the polish would be hardened
onto the components at that point...

This is all just my best guess, so I could be wrong about any of it. Best of luck.

Just opened it and the water seems to be under the fan area.

Could it possibly be condensation? Dried it all out with a hair dryer.

If the water got inside the console and you tried turning it on then unfortunately the console is now completely dead, water damage will only affect the console if it is on or attempted to be turned on when water gets inside.

Your only option would be to send it in for repair now.

The xbox one and xbox one s do not have any water inside them atall, The heatsinks are solid aluminium with copper cooling pipes running through them, These copper pipes do contain a liquid but it is not water and it is only a few drops.

The xbox one x however uses a vapour chamber on its heatsink to help disperse heat but the amount of liquid inside of that is miniscule and could not leak causing a puddle.
