Step. 11 Disabling "USB Selective suspend setting"
Some customers experience that touch is lost after 15 minutes. This is because the i3TOUCH
touch sensor is feeded by the power supplied from the USB-port of the computer and some
computers have "USB selective suspend setting" enabled to save power. Go to Control
Panel\All Control Panel Items\Power Options\Edit Plan Settings. Click "change advanced power
settings".
For each power plan used (!) click USB Settings -> USB selective suspend settings -> disable
both "On Battery" and "Plugged In"
