laptop battery suking dik

i got a toshiba satellite laptop at home that is less than a year old.  lately the battery life has taken a nosedive. i usually leave the computer charging when i'm not using it.  google said others had similar problems..  am i pretty much fucked?

fuck, now my toshiba power saver thing is not even reading the battery level correctly.. it stays at 100% until it's almost out then it skips to 7%.. then it goes out after a little while.
