I have been using lenovo, think pad T440p since November, 2014. Till before 3 month it had battery back-up around 5-6 hours and gradually started decreasing up to 2 hours on last week. But, then a message' The Battery has failed due to normal wear. The battery can not be charge. Replace the batter' occurs. Now the battery is not working.
Should i have to replace the battery or it is only software problem ?
