Weird battery problem, Aspire 5024

I have a problem that I am pretty lost about right now... I have always been getting about 3-3.5 hours of battery time from my Aspire (Undervolted). Yesterday I unplugged my computer and the battery gauge was only showing like 1.45 hrs. At first I was thinking that this was a display error, but it really is draining fast %-wise. So, I let it drain to 1% and charged it all the way to 100% hoping that it would return to normal, but no such luck.
The battery is showing 0% wear, so its not a battery problem, my computer is just draining more power than it used to it seems...
Anyone have any idea how to fix this? I don't know exactly when it happened, but I haven't really installed anything that would affect it in this way...

Thanks

 

check your clockspeed with CPU-Z or a similar app, if it's at its maximum, it might also be running the fan constantly, hence the lower battery life. i'm just speculating though.

 

I should have made this clear in my first post I guess, but was in a rush.
The CPU is correctly speedstepping, it is undervolted and has been working just dandy up until recently. Notebook Hardware Control shows a battery drain of around 26-28 W. Can someone check what their computer is draining while on battery? Preferably someone with a Turion ML-34, but any kind of indication would be great!
