locked screen

this ipad was found at my fathers work the owner has not locked it down with icloud is there anyway i can get into the home screen or if worse comes to worse factory reset if to stop it being a waste of a perfectly good ipad

When I put my ipad to "sleep / standby / lock screen" or whatever, if it is unplugged, it stays off. However if it is plugged in, it will blink every minute or so to let me know the battery is full. It is in a square stand, so it is going to be plugged in and on standby fairly often. My Ipad...
