[B216]Battery And Power Supply

by Roberto Sedycias, Rob

Depending upon the model, a notebook battery usually lasts from 1 to 8 hours. However, with efficient battery usage, an hour or two of battery power can significantly be increased. You can save battery power by using the built-in battery saving modes and by following good notebook battery-saving practices.

Built-in battery-saving modes are Stand By and Hibernate. In the Stand By mode, open applications are stored in the RAM, the hard disks power down, the monitor switches off, but the processor goes on running. When you again perform some activity of the mouse or the keyboard, then the hard disk powers up, the monitor switches on, and the data from the RAM is activated, restoring your notebook exactly the way you left it.

The Hibernation mode is used when the notebook is left unattended for a long time. The open applications are stored on the hard disk, which subsequently powers down, the monitor turns off, and the processor turns off going in for hibernation. On soft rebooting like a restart or wake up on LAN, the processor turns on, the laptop wakes up, and the same exact settings are restored. Both these modes should be used to conserve battery power. You can preset your preferences in the settings of your notebook, so that in case you doze off, or leave the device for a coffee or a snack, the notebook automatically goes into any one of these power saving modes.

Following battery-saving practices can also save notebook battery power. You should always adjust the monitor controls to suit the room lighting conditions. Dimming the contrast and brightness saves battery power besides providing relief to your eyes. Auto-save and auto-update features of applications start in the background without your knowledge and these should be disabled. External devices consume a lot of battery power, hence the usage of external mice, monitors, keyboards, optical drives, videocam, digital cameras, or any other device connected to the PC Card slot, VGA/ FireWire/ USB port should be avoided.

Increase the RAM memory, if an extra slot is available, as this puts fewer burdens on the hard disk, which consumes a lot of battery power. Avoid multimedia games while you are running your notebook on battery power. Similarly, avoid music or movies. Copy the CD/DVD on the hard disk and play it from there, instead of the optical drive. Disable WiFi and Bluetooth. Built-in wireless cards should also be disabled. Decrease or set to mute the notebook speaker volume. Turn off all preprogrammed scheduled tasks. All unused open applications should be closed. The general guideline is that when your notebook is on battery power, you should perform only such operations, which are the need of the hour. Rest of the applications can be performed, when your notebook is connected to the mains.

Keeping good care of the battery also prolongs its life. To maximize performance of nickel-metal hydride batteries, they have to be completely drained off before they are recharged. However, lithium-ion batteries do not need cycling/ conditioning, and they do not suffer from memory effects. Hence, they need not be fully drained off before recharging. When the notebook is not in use for an extended period, the battery pack should be removed to avoid battery leakage. Before removing the battery pack, you should charge it fully and then remove it, as all kinds of batteries should always be stored in a fully charged state. Do not store your battery pack along with metal parts, as this will short-circuit your battery.

Utilizing the built-in battery saving options and other means, you can significantly add one to three hours more in the total capacity of your notebook battery. Sometimes, in critical situations, like an important meeting, this extra hour of notebook battery power can help you clinch your desired deal.

Obviously, the primary advantage of laptops is mobility. Of course, however, laptops need electricity to operate on. Even though electrical outlets are plentiful and can be found nearly everywhere, there are times when we have to fall back to utilizing the laptop's battery - airplane trips, meetings, etc. I have also seen sudden power failures when I could have missed all my work if the laptop didn't have a loaded battery. Despite the ongoing evolution of battery technology, there are limits to their usage, and that leads to a discussion of ways to preserve and improve battery functionality.

Just as appropriate consumption and upkeep of your automobile will result in longer life and better performance, adopting certain steps with your portable electronics? batteries will result in longer use per charge, and a longer whole battery life. With replacement laptop batteries ranging from anywhere between $100.00 and $300.00, getting all the consumption you can out of your battery will save you lots of aggravation and keep more money in your pocketbook longer.

As soon as your portable gadget goes out of the maker's location, its battery starts losing capacity to store a charge. In some cases, it may indicate a lot more power stored than there really is. You may end up draining the available power without being aware of it, and the computer may end up shutting down and cause you to lose the work you've already finished. Now that is not a situation you want to find yourself in. It is inevitable after a certain period of time, as the battery goes through gradual degradation. Nevertheless, there are means to stretch your battery life.

If your gadget always (or usually) functions on outside power, you may be inadvertently decreasing your battery life. At least once a month, let the device consume all the battery power. In other words, let the battery drain until the computer rests ("hibernate mode") and then let it re-charge. This can help avoid capacity degradation.

Some laptops have a ?recondition? feature built into their systems, using a blend of specialized hardware, intelligent batteries, and special programs running in the background. This feature will automatically prompt you to condition your battery and then attempt to do so in the background. If you are reminded by your system to condition your battery, you should probably allow it to do this.

Operating temperature is another important factor when we talk about battery life. Exceedingly high temperatures can cause your laptop batteries to break down faster, just as extreme low temperatures can damage batteries, so don't leave your notebook in your car for extended periods on hot days or overnight on cold nights.

Some people just plug their laptops into an electrical outlet and use them without a spare battery in the bay. It is recommended that you do not use your laptop without a battery in the bay, since the electrical terminals in the battery bay of your laptop may get filthy or get rusted. It should be averted for these grounds, plus the fact that you may lose your work since there is no backup power supply.

Despite the fact that advanced monitors do not eat up a lot of electricity, monitors, hard drives, and the CPU are the three biggest electricity consumers on your laptop. Big, brilliant LCD monitors with backlights call for relatively considerable quantities of electrical power, as do the gyrating motors and actuators within hard drives. It is a good idea to shut your monitor off when you are not using it.
