I bought a Toshiba Notebook soon after Windows
Vista was released and was wondering about the huge
battery drain whenever I was using the Notebook without a power source. The battery drain is
apparently caused by the Aero theme and the power settings for the wireless adapter. I was not even sure at the beginning if I was running
Windows Aero or just a different interface but soon found out that the Aero interface, one of the few new things in
Windows Vista, was active and draining battery life like crazy. I decided to disable the Aero interface because I could not see the use of it after all. Sure, it offers some nice looking effects but that is not the main purpose that I’m using the notebook after all.
To disable the Aero theme do the following:
Right-click on your desktop and select Personalize from the menu. Choose Windows Color and Appearance and click on Open Classic Appearance Properties for more color options. Select a different theme from the list (non Aero) and click on Apply.
The second battery drainer could be a wrong power setting. If you left-click the little battery icon in the system tray you see which power setting is currently used. I suggest you select the power saver option if the notebook is not connected to a power source. All other settings drain the battery pretty fast.
