Logitech Wireless Mouse M235

view story

http://askubuntu.com – I bought a Logitech M235 mouse. This works perfectly under Windows.Basically, it works on Ubuntu and is identified as M305. This problem only occurs when the laptop is running on battery power: When I don't use the mouse longer than 5 seconds, it does not works for a few seconds. How can I stop this? (HowTos)
