Getting the most out of your Dell laptop battery can take some careful planning and lateral thinking. The important thing to remember is that laptops, although powerful, do not have an endless amount of power and should only be used to perform essential tasks and save the multitasking for a computer that has unlimited resources.
Turn Down The Brightness
Computer screen brightness, especially on laptops, is simple to turn down. Often, all that is required to do so is pressing a built-in keyboard key, or pressing a shortcut for your operating system. Reducing the brightness of the screen means that the computer does not have to use as much power to make the light output brighter, therefore saving power.
Staying organized and working on only one task at a time can help your battery last longer. This is because the greater number of programs running at any one time causes the computer to work harder. By closing down all but one application, you ensure that you are getting the most from your HP laptop battery. Consider also the programs that are running without you knowing. Things such as searches, widgets and gadgets can eat into your battery life without you noticing. Shut them down when not in direct use.
The fewer external devices you use in conjunction with your laptop the longer the battery will last. Things such as flash drives, mouse, keyboard, and anything else that is plugged into your laptop, all drain extra power. Unless you absolutely need them, do not use external devices with your laptop.
Go It Alone
Staying disconnected from the Internet can make your laptop battery last a lot longer. Even when you are not actively browsing, your laptop constantly monitors the connection and performs connectivity checks. When you are not using the Internet, disconnect your wireless option. You can always turn it back on when you need it. The same applies for Bluetooth capabilities.
Make sure that your battery gets regular exercise. It is important that your battery is not left uncharged for long periods of time. Apple macbook battery, recommends not leaving a battery uncharged for more than three weeks. Older batteries may also suffer from what is commonly known as the "Memory Effect," which occurs if a laptop battery is not allowed to charge up and it runs down. For example, if it is always plugged into a socket and not used on the move. Not allowing your battery to run down fully often results in it being unable to hold a charge. This is not an issue with modern Li-ion batteries.
