With win7 I had about 4hrs battery life. My battery was fully charged and I had my laptop plugged in during the entire install of ubuntu. However, about 15 minutes after unplugging my laptop I get a message that says I only have 19 minutes of battery left. So now instead of 4 hours of battery I only have 45 minutes max. WTF?
Everything I've researched so far seems to say things like "change your power settings" "dim your screen" etc. But none of these 'solutions' would in anyway account for a missing 3 hours of battery life.
So is this an issue with the battery monitor itself? How do I fix this? I came to Ubuntu because I'm starting to learn some programming and my win7 was gettting too buggy. I really don't want to go back now that I've seen what ubuntu is, but I can't function with only a half hour battery that I KNOW will last at least 3 hours. Please help!
