Tip & How-To about Computers & Internet
There are certain elementary rules for getting more
from your laptop battery. Make it a
point to turn off Wi-Fi and BlueTooth. You are aware that most
laptops have shortcut keys to instantly disable wireless networking.
Completely avoid playing computer games, music or DVD movies as
multimedia activities tend to drain laptop batteries.
Disconnect all external devices like PC Card modems, firewire, USB
devices and optical drives. It is advisable to use the notebook
touchpad instead of an external mouse. It will also help to adjust
your screen brightness as dimming your display saves battery power.
You'll certainly need to see your screen, but just how bright do you
need it to be? Screens lighted at full strength eat up 15 percent more
battery life than if your battery was at 50 percent brightness. So,
be sure to squeeze more life out of your laptop by reducing the
brightness of your monitor a great deal.
Select a laptop power scheme that turns off the notebook monitor and hard disk after 10 minutes of inactivity. Remember to decrease or mute the laptop speaker volume. Lastly, programs that are run from a CD or DVD can be copied and run from the hard drive, which typically consumes less power than an optical drive. Some games offer you the choice to install to the hard drive, so choose this option, as you will get more life out of your laptop than using the CD-ROM or DVD player, which are massive battery consumers. There are also some more tips to improve your laptop battery life. If you do not use your laptop for extended periods of time like a few days or a week, then remove the battery pack from the laptop. Never expose the battery to high heat or extreme cold conditions. For instance, do not leave your battery in your car during the summer months. Hot batteries discharge very quickly, and cold ones can't create as much power. Make it a point to plug your laptop charger adapter into a UPS and not directly into a power outlet or surge protector. Fully charge new battery packs before use. New pack needs to be fully charged and discharged (cycled) a few times before it can qualify to full capacity. Leaving a battery in a laptop while using an electrical outlet for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.
Energy management has been a problem since the earliest days of mobile computing. Drains on a battery include virtually every component on your laptop, including the screen, the hard drive, the CD-ROM and DVD-ROM, and other peripherals. The biggest villain is DVD movie, which cause the screen to run at full power for the life of the movie. Make sure you have no devices plugged into the laptop that can drain its power, such as a webcam, USB thumb-stick, or wireless PC card. According to laptop manufacturers, connected peripherals can impact battery life by up to 12 percent (depending on the peripheral), so get used to the touchpad instead of using an external mouse when you're away from an electrical outlet. As a ‘Prevention is better than cure’ philosophy, it is worth mentioning that air travelers should make it a point to recharge the battery before a flight. Find an electrical outlet while you're waiting for your flight at the gate, a restaurant, or departure lounge.
