So I woke up this morning, and my mouse, a Logitech M705, was on my kitchen counter where I left it. I picked it up and placed it on the table where I would go to use it a few minutes later. When I sat down to use it, it was laying in a mouse-shaped puddle of water. There was no water on my counter, and no water had been on the table when I put the mouse down.
Before going to bed, I turned the mouse off using the switch underneath and rested it on the kitchen counter as I do every night. I don't leave it on the table because I have a cat, and I don't want to have to look for it on the floor in the morning (good boy stays off the counter).
The mouse powered on okay and clearly right-clicked without issue, but tracking was a problem as water had gotten inside. The batteries are 2 Energizer AA alkalines. They were undamaged and function normally, but there was a bit of water inside the compartment (underside of the mouse). The mouse has now dried out and works fine.
The question is how did water accumulate inside the mouse overnight? As I stated, it was not powered on, the switch was in the off position. Also, I'm in the Arizona desert where the humidity is currently only 18% with my humidifier on. Even overnight, it never gets above 50%. Any theories or explanations are welcomed.
