So a couple of nights ago I was pretty drunk and sleeping when I awoke to a loud noise, which I ignored. Then the next morning I woke up and realized that a glass of water had fallen over and onto the floor. I didn't think much of it until now, but I think you can guess where this is going.

My U9BLS suddenly stopped working properly. The space bar, escape, g, h, ', and up arrow keys no longer work. I unplugged the board and took it apart. This is where it gets weird, I tried shorting the solder points for some keys, and the keys that I mentioned still didn't respond. The other keys I tried did respond to this.

So the problem isn't with the switches themselves, but with something else. (unless my logic is flawed, shorting the solder points should bypass a faulty switch)

I'm at university so I can't really desolder the switches (which I don't think would matter based on the line above)

Relevant info:

1. it was water that spilled, and I don't know how much actually got on the board
2. there was about 48 hours between the time it spilled and the time it stopped working
3. the affected keys are not located near eachother on the board except for the g and h keys
4. I tried the board on a different computer and the same symptoms exist
5. same thing happens when plugged in with USB and PS2
6. all the LED's still work fine

I searched through the Wiki on here to no avail. The section about fixing keys seems to focus on the switches being faulty or corroded, which they don't seem to be (because of the issue with shorting the solder points)

Well, that is about as much as I can say for now. If anyone has any ideas I'd love to hear them

Thanks <3

If water spills into a keyboard, as long as you unplug it and dry it with a hair dryer and then let it dry for awhile, it should hopefully be okay. But since water spilled into the keyboard while you were sleeping and it was still on the entire time, it's probably done for.

OCN has a wiki?

I'd recommend opening up the keyboard. Might be as simple as water in the cable connector shorting it out.

I'd say the board is boned, because it was on for quite awhile with the water in it.

I dropped my Sansa Clip into a toilet bowl while peeing WHILE ON (it immediate fizzled out in the bowl) and it came back fine after blowdrying with my DataVac.

Ewwww.......

I'm always amazed how many keyboards DO come back fine but:

1. It's a backlit Xarmor.
2. It's Xarmor.

Lol, original thread was on geekhack. This is copypasta.

These are NO Momentary switches btw. I still suspect water in the switches.

NO means Normally Open.

And when drunk I do recommend drinking lots of water.

Yeah, that's why when you trip the solder points for the switches on the back of the PCB, it closes the circuit for that key and registers a keystroke. However, this was not the case for the keys that were effected by the spill, meaning the switches are not the cause for the problem. I suspect it is the diodes, but it's not so easy to tell which solder points are for the diodes :/

I'll keep messing with it and report back with my findings as well as some pictures. I'm hoping this is repairable, even though it will most certainly require everything being de-soldered in order to access the bad diodes on the top of the PCB (plate mounted switches can be a PITA lol).

Thanks for the replys

And *** why no ripster at geekhack? This makes me a very sad panda.

Actually it's more complicated than that because of the diodes. If you have MULTIPLE switches registered as closed you might be confusing the controller.

In other words it may yet fix itself. Shake your keyboard like a polaroid picture. Prop up sideways. Dry mild heat. Patience.

I think the moisture is all out of the board by now since it's been a couple days since it happened and it's been apart the whole time, but I'll give it a few more days and try it again.
