I think it's better to say 31 amps at 12 volts and 3 amps at 120 volts, both totaling to 375 watts.
Thank you for saying this, I think my head was about to explode from the people trying to figure out how it stuff works.
I make sure to maintain my keyboard being clean by making sure my hands are clean every time I use them. Sadly over time they can get dirty which just means I have to take it apart, and wash it. I've only gone though one keyboard, and the last time died because of a defect in the usb/ps2 aspect of it so I had to replace it. My roommate goes though keyboards every year I think it’s because he eats over it and basically lives at his desk while taking little or no care about it. His last keyboard was growing mold on it which is how that ended, I told his wife to stop buying wireless keyboards for him if he’s going to go though them every year.
Now if we were talking about mice, due to my gaming habits I think I've got though 6 of them, sadly the left clicker wears out, and I've tried many attempts to fixing them in the past with no luck, sadly my first mouse died for other reason but it could be the issues I have with mice now are because of the brand since I switched after that first one and had so many issues since.
Reference the NULL within NULL, it is the gateway to all wizardry.
