Wireless mouse erratic behaviour

We recently received a call from a customer that the brand new wireless mouse that they had received for Christmas, was acting erratically.

It seemed to have a mind of its own. The cursor would either lag behind or jump in front of their hand movements and was driving the customer batty.

Upon arrival at the customer’s home, I saw that the wireless mouse transmitting device, was plugged into the USB port on the front of her desktop computer.

I have discovered in my years of working in the ICT field, that having a transmitter so close to the desktop box can cause problems, because the electrical signals being emitted by the computer itself can swamp the mouse signals.

Luckily I had a short 12″ USB extension cable in my toolbox. Plugging the mouse transmitter into this extension cable immediately cured the problem.

Needless to say, the customer was very happy as this was a present from her daughter and she didn’t want to have to try to tell her daughter that her very thoughtful gift didn’t work.

Happy New Year everyone!
