I have no idea why but over the past two weeks or so i have noticed that my powerbook 1.5GHZ 1GB RAM has been losing a lot of battery life. I get it FULLY charged then unplug it and it says i have roughly 1 hour and 20 minutes left. My laptop is 4 years old, I'ts not a relic, it does everything i need it to do and I still love it, but I have no idea what brought this stinking battery life issue on, any help at all? I always hit better battery life at the top. Is there any way i can check the condition of the battery? I can't afford a Macbook Pro...yet.... thanks
