Tips to extend your IBM battery life

Sleep Is Good
1.Use laptop's power management features to set targets for when the machine will slip into sleep mode(say,after 2 minutes of inactivity) and set the notebook to hibernate when you close the lip.This will help you save IBM battery power during the business trip or vacation. 
Dim the Lights
2.Turn down the brightness of the LCD panel or use function key (Fn), and the corresponding key to lower the resolution on your screen as low as you can.
Banish Non-Essential Components
3.When you aren't using the Bluetooth, Wi-Fi and IR devices,just turn them off.It's crucial when you're on IBM battery power,especially when your aren't close to a power source.
Turn Off the Autosave Function
4.MS-Word’s and Excel’s autosave functions are great but because they keep saving regular intervals, they work your hard driver harder than it may have to.Disabling the autosave feature from these applications will help you save power and prolong the IBM battery life.
