How to Ensure your Laptopís Battery Lasts Longer

In recent times, laptops have become an essential part of day-to-day life. Mobile technology has progressed so much that laptops outsell desktops. Though mobile technology has advanced, the average laptop battery life is still a bit on the low side, between two to four hours if the laptop is used continuously. It isnít all that much, especially if you are regularly on the move.

Therefore, unless you have extra battery packs, conserving your batteryís life while you are on the move is crucial. So, how can you prolong the life of a laptop battery while youíre on the move? The answer lies in:

- Using laptop resources conservatively, and...
- Configuring your laptop for optimal power saving.

Use Laptop Resources Conservatively
All resources require power. However, some resources require more power than others. To get the most out of your battery while on the go, you should ensure resources that use substantial power are not used or are used only when needed. The following list contains some examples:

- CDs and DVDs: Playing CDs and DVDs is an energy sapping action. While on the move, eject CDs/DVDs out of the drive.

- Wi-Fi: Not always do you need a connection to the Internet. Switch Wi-Fi off.

- External Connections: Devices that connect to the laptop, such as an iPod or an external hard drive need power. Unplug external connections.

- Speakers: Using any sound effects, such as when you receive a mail, requires power. Mute your speakers.

- Software Installation: While installing software, the laptop extensively uses three key resources Hard Drive, CD/DVD Drive, and Microprocessor. Each of these resources drains the battery. Donít install software while on the move.

General Rule: Donít use any resources for actions that can wait till you have plugged in the laptop to the mains power supply.


Configure your Laptop for Optimal Power Saving
Windows enables you to control the dimness of the screen and set power consumption settings for optimized performance.

Optimize Power Options
If miserly power consumption is your top priority, ensure the settings in Power Options reflect this. Hereís how:

1) Click Start and then Control Panel.


2) Double-click Power Options.


3) Set the Power Schemes to Laptop.

4) Click Advanced.


5) Select the appropriate option from the Power Buttons section.


6) Click OK to save changes.

Congratulations! Youíve set the power options for your laptop. Though this does help in maximizing the life of your battery, it does not help reduce the load taken by the most power-intensive component - the laptop screen. You obviously canít do without the screen so switching it off while working is not an option.
You can, however, reduce the power consumption by setting the dimness to a lower level. By using the default Power Options that comes with Windows (which weíve just shown you), it is not possible to set the dimness of the screen. To set the dimness, you need download Power Management software. Most laptops nowadays come with one pre-installed. The Power Management software provides more power management options and also changes the look and feel of the Power Options dialog box. So, donít be alarmed.
By following these tips, you should be able to get maximum battery life while youíre on the move.
