Ask: Lack of grounding may cause USB mouse to go nuts!


This is the third USB mouse that has gone nuts. After roughly what may be two, three months of buying and using, the mouse starts to frequently send two signals instead of one back to the CPU when the left button is clicked. The end result is that instead of a single click, a quick double quick operation is performed, which gets thoroughly annoying considering that your applications start to magically close, fail to minimise or maximise, or any number of other behaviours.

Blaming the USB mouse of being faulty and of inferior quality, I would have bought a new one, had it not been for the comment Tili made where he acknowledged having experienced pretty much the exact same behaviour before. He postulates that the cause was likely the lack of grounding in his case. He might not be entirely off-base with that theory. I don’t have grounding at home. Consequently, I can get bitten on my bad days by current dancing on metallic surfaces, not least computer chassis. Though I use the USB mouse in question with my laptop as an external device, I have felt charges on metallic portions of the laptop before. Could it really be the lack of grounding that is messing up the circuitry inside those mice?

What do you think? Have you had similar experiences? Or, do you think Tili and I have nothing better to do with our time?
