2. Which Registry Settings Extend Battery Life?
Well, the whole premise here is that by default, Windows XP and Vista is very aggressive on increasing the speed of the processor and conservative on lowering the speed. This spells bad news for the battery life because you tend to overspend the battery than save it.
So here's what you do. Go to the Start Menu and click on Run. Type regedit into the
dialog box and press Enter. This brings you into the Windows Registry Editor (be careful here).
Search (Ctrl-F) for a registry key called KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager.
Next, create a new key called Throttle. Inside this Throttle key add these dword decimal values.
