and while on battery it will not uise battery power to work, it will only use wapda, so no extra cost of elctericity..
Are you sure it will not use battery power? because someone from the computer shop told me that all battery-powered devices always use battery to power the device, no matter they are connected to electricity or not.
When they are connected to electricity, first the battery gets power and then it transmit the current to the device, so battery will always be in use until you fully take it out.
