Sony Vaio Pro doesn't work without charger

[ribagorza]

Recently my Vaio stopped working on it's battery. It only works with the charger connected. On the battery information it says that the battery is at 79% (at which it has been for a while now), but when I take the charger out the computer shuts down immediately. Does anybody know what the problem is?

Hi! 

After talking to sony, they decided to send me a new battery. After maybe a month I got the battery, but i didn't know how to change it. So I went here to ask for help and saw that you guys had come up with a solution. And it worked for me also, so thanks! Now I have a working battery in my vaio and a new battery from sony. So I'm thinking I'll save the new battery until the one I have starts getting bad. But the problem is I don't know how to change it, so I was wondering if anybody knew? My model is SVP1321C5E. Tried searching for it, but I didn't find anything.

Having the same problem with my vaio pro 13, battery indicator stopped at 73%.

Been using this unit for the past 2 years, is it my battery need to be replaced?
