Helo guys.. Eee PC 1015PEM user reporting in..

Just purchased this unit days ago from a non-forumer, everything seems fine its just that there's a notification at the batt status that say 'consider to replace your battery'.. and i've fully charge the batt 100% but its drain to 40% in just an hour! This is opposed the spec sheet says this model can hold up to 10hrs of operation.. even set to power save doesnt cure the prob.. suspected the batt is passing out already..
Do i need to replace the batt? How much the cost?
TQ!
