If this is in the wrong category I apologize. I have tried to research this problem myself but there is a surprising lack of information available about keyboards. Anyways, I spilled water on my keyboard and it caused keys to stop working, is there a better solution than buying a new keyboard?

Details: I bought the keyboard second hand so no chance of warranty. I have spilled water on it before this time I just forgot to give it time to dry. The keys not working are the Space Bar, M, N, and right Shift. I took it apart, the inside is spotless. All other functions work. Logitech support had me uninstall their software and drivers to try and reinstall, did not solve the problem.

IMPORTANT: When I plugged it in after drying it, it worked flawlessly. I restarted computer and that is when the keys quit working.

My Thoughts: Where is the gap in the circuit? I also noticed that the Space Bar, M, and N all share the same wire path on one of the layers.

I can get pictures.

By pinching the plastic layers together on the wiring circles (where a key would press) I can make it type all other letters, when I pinch together the keys mentioned above, nothing happens.

If a extreme cleaning doesn't do it. It is probably not going to be fixable.

Sounds likes one of the input channels is bad, not a lot you can do about that as most keyboards chips are potted. You can get down to them, but it is a messy affair, and finding a replacement chip can be tricky, as the potting will have removed the labels from many chip types. If the runs in the membrane are bad, you can try to bridge any visible gaps. Other options would be to locate a G110 with a bad display on ebay or something and start swapping parts. They just don't want you to repair these things.

Aside from stripping the whole thing down and checking for physical signs of an electrical short, not really. The keyboard's membrane circuitry is more or less waterproof, but if you've gotten water under some of the contact pads that would cause keys to stay pressed or act if they have been pressed. Most general keyboards only let you press so many buttons together, though I think the G110 can handle quite a few. If the chip itself is damaged, you may as well write it off, and that is harder to determine.

A mechanical keyboard might be more time consuming, but easier to repair.

I left my window open when i went to work and there was a snow storm. When I came back my keyboard was covered in snow but the lights where still on o_O After freaking out I faced it up side down to dry out. At this moment there are tiny drops in between the keys and it still works. same for my mouse G100s Ligitech. Though Im happy I dont know how this is possible. Its it water proof?

Arise thread!

Membrane keyboards are more or less waterproof, yes. Cheaper ones can even be put in dishwashers with a reasonable chance of surviving.

G series ones with the screens less so, but a little bit of snow shouldn't be too bad. That will just pool on the plastic chassis between the keys on both the inside and outside before getting inside to get to the circuitry.
