Things You Can Do To Help Conserve The Charge In Your laptop's battery
I always find that mine runs out at the most inopportune moment. So here are some suggestions intended to help you get the most out of the charge in your laptop's battery thereby enabling you to get that important objective achieved or maybe just to give you enough time to finish the level in your favourite game.
1. Turn off Wi-Fi and/or BlueTooth when not needed. Note. Most laptops have shortcut keys to instantly enable/disable Bluetooth and wireless networking.
2. Playing games, music or DVD movies - Multimedia activities - tend to impose the highest load on a laptop's battery. Therefore unless these activities are essential try to minimise the amount of time spent on these until a mains power supply becomes available.
3. Disconnect all non-essential external devices. E.g. PC Card modems, Firewire, USB devices and optical drives. Use the notebook's built-in touchpad in preference to an external mouse.
4. Adjust your screen brightness - Dimming your display to the point where brightness is reduced but still bright enough to see without difficulty helps conserve battery power.
5. Check and, if possible, tweak your laptop's Windows power options - Choose a Laptop power scheme that turns off the notebook monitor and hard disk after 5 minutes of inactivity. Not sure whether to use sleep or standby modes? Take a look at the following explanation
Standby mode: Use standby to save power when you will be away from the computer for a short time while working - your monitor and hard disks turn off, all applications and open files are stored in RAM. When you want to use the computer again, it comes out of standby quickly, and your desktop is restored exactly as you left it.
Hibernation Mode: Use hibernation to save power when you will be away from the computer for an extended time while working - your computer shuts down to save power but first saves everything in memory on your hard disk. When you restart the computer, your desktop is restored exactly as you left it.
6. Reduce or, better still, mute speaker volume.
7. Turn off all non-essential scheduled tasks.
8. Turn off the auto-save features in Microsoft Office and other applications - Note. Only do this if you're aware of the implications of doing this.
9. Try to keep your laptop cool - Make sure you're not inadvertently blocking the cooling vents because the hotter the laptop and its battery get the less efficient they become.
10. Use the optical drive less - If you have programs or data that are normally stored on a CD or DVD investigate whether any or all of these can be copied to and run from the laptop's internal hard drive as a power conserving measure.
