Poor Battery Life

If you find that your laptop's battery life is not up to scratch, it is likely that the problem lies in your power management settings rather than with the battery itself. While all batteries inevitably deteriorate over time, changing certain power settings can help you to get much more use out of your computer when you're on the move. Windows 7, compared to its predecessors, is relatively conservative when it comes to battery life and there are many settings and power plans provided for various situations. Follow these steps to increase battery life before you consider buying a new battery.

1 - Check Running Programs
If you constantly hear the fan inside your laptop, it's most likely that the processor is working at full load all the time. This drains battery power very quickly. Of course, various tasks, applications and video games use the processor to its maximum load. However, if you still find that the fan is humming when you're merely browsing the Internet or writing a document, there may be something else running in the background.
Right-click on the taskbar and click "Start Task Manager." Click the "Processes" tab and then click the "CPU" column so that the processes and running programs on your computer are arranged by the amount of processor power they're using. Take a look what is at the top, using all of the power. It could be a program which is not responding properly, a malicious piece of software or something else which you weren't aware of, such as antivirus software scanning the computer in the background.
You can close the process by right-clicking on it and clicking "End Process." If you're not sure what the process is, look it up on the Internet.

2 - Change Your Power Plan
Laptop computers have various power plans, including ones which are optimal for using when the computer is running off the battery. To access the settings, right-click on the battery icon in the system tray in the bottom-right of the screen and click "Power Options."
Choose the plan which best suits the situation. Clicking on the arrow beside "Show additional plans" will show any other pre-configured plans for your computer, such as the "Power Saver" plan. Choose this plan if you want to get the most battery time.
Alternatively, you can customize an existing plan or create a new one. You'll be able to choose different settings for when the computer is running off the mains power or for when it's running off the battery.

3 - Turn Down Your Monitor Brightness
The brightness of your monitor makes one of the greatest impacts on power usage. Screen brightness can also be configured within the Power Options control panel which is mentioned in Step 2.
You can also change the screen brightness by using the shortcuts on your keyboard. Most laptop keyboards provide a function key labelled "Fn" and two keys for increasing and decreasing the brightness. If this is the case, press and hold the "Fn" key and press the brightness keys as required.
