Logitech Bluetooth Keyboard

Trish's keyboard seems to randomly type letters and numbers when she's not touching it. Leo suspects the keyboard could have shorted out or the USB port it's plugged into is shorting out. She should try a different keyboard. If that doesn't fix it, then that would point to a different problem. Leo also suspects that the computer may still be paired to the wireless keyboard and her daughter is playing with it, causing the issue!
