Adam@PCTorque: Are you really sure that you activated
PowerNow! in Windows XP when you did the battery test?
It dosen't seem to me like you did, so you should ativate it by selecting Portable/Laptop in Control Panel>>Power Options>>Power Schemes that looks something like this:

Then you should be able to use AMD's PowerNow! Dashboard to monitor your system and to make sure that PowerNow! really is active and it looks something like this:

You can download the AMD PowerNow! Dashboard from here:

Also make sure that you've installed the latest AMD Athlon 64 Processor Driver for Windows XP that you can download from here:

Enabling this should extend the battery life significantly, and reducing CPU heat dissipation and thus providing an even cooler and quieter-running system
