according to my battery health,

""Your battery is able to charge normally. However it is reaching the end of its usable life. You can experience longer operating time with a new battery. You might want to consider purchasing a replacement battery now.""

What should i do? This coming July my Studio 15 going to be 1 year ONLY and the battery is reaching its end of life? Sigh... Most of the time i plug in the adapter together with the battery intact. When i put the laptop to sleep mode at night, i still ON the adapter until the next morning, with the battery intact as well... Is it cause by that??

how much is the replacement battery for studio 1555??? Mine almost 1 year. Sigh =(
