Some Ways to Save Laptop Battery Power when you really need batteries

You have a five-hour flight from Los Angeles to New York, and a battery on your laptop. You work to do, to watch movies, and games to play. How will that make the battery last? Well, hidden inside (and outside) your computer a lot of tricks to help you.

Darkening of your screen

Your screen and hard drive use more battery than other parts of your computer. You can turn the screen down to a point in your eyes still feels comfortable, but also save energy. In most laptops, first dim screen, hold down the "Fn" key (go ahead and find, because you may never have used before). Then you look for a key on your laptop or have a picture of a sun or half moon. (On my Sony Vaio that key happens to be F5.) If you find it, go ahead and hit him while holding down the Fn key. A brightness adjustment box should appear on your screen. If you can not find a key with a sun and crescent on it, try to hit your arrow keys while holding several Fn, to see if it works.

Hide full screen

If dimming your screen is good for saving battery life, turn it off when not in use, is still best. To turn off the screen, we'll have to go to some adjustments in the control panel. Soon we will see these values are not only good to turn off the screens, carrying out a whole series of battery saving functions.

Click Start, then Control Panel. If your control panel shown in the "View" first click Performance and Maintenance, then Power Options. If Control Panel is in Classic View, click the Options icon energy. Click Next on the Power Schemes tab. Below where it says running on batteries and the other side where it says Turn Off Monitor, choose the speed that you want your monitor power down when you're not actively using it.

That picture of the Power Options Properties, we just opened brings us a lot of other attractive options that we can use in our cross-country flight!

Selection of a power

Windows XP offers two power systems suitable for laptops on the go. This is portable equipment and maximum battery life. Both can be chosen on the Power Schemes tab of the Properties box Power Options. Both power schemes conserve battery power. But laptop notebook complies with retaining the amount of energy needed at the time, while Max battery is much less flexible. Keeps your PC at a rate far low constant power regardless of what you can do. So if you plan to watch a DVD on that flight, which uses a lot of battery power, not recommend using the combination of battery power Max. You may not give enough power.

Each power scheme also has its own settings for when the monitor and hard drives must be turned off. Remember that both are voracious consumers of enormous energy, and that both the monitor and the hard drive stay longer in portable equipment do so at the top of the battery.

The power scheme you choose also determines how long the team will wait to enter Standby or Hibernate after remaining idle. Standby conserves energy by turning off the hard disk and monitor. But whatever he was working at the time stays in memory (RAM) instead of being held securely to your hard drive. The side Sleep positive, however, is that when a key is pressed the computer goes out as quickly.

Hibernation saves even more energy because it saves your work on the hard drive and then shuts your computer almost the whole way. By itself, of course, this means the team now needs to raise to normal, but when everything comes back, looks the same as before. For the device to Standby mode manually, click Start, click Shut Down, then Standby. To make your computer from hibernation manually, click Start, Turn Off Computer again, this time holding down the Shift key after. The expected key switches to "Hibernate". Click on it and his team will go to hibernate mode.

Create Their own profiles

Maybe you do not like the two power-saving options Windows gives. You may want to create custom reports to meet their own needs. You can do that! I created one for "Long Plane Rides." I adjusted the settings in the Properties box Power Options. For example, I indicated that I wanted my monitor turns off after only 2 minutes of downtime, and my hard disk after 3 minutes. Then I clicked on Save As, name of my profile, and click OK. Now maybe the battery will last longer in flight.

Let's review some other options in the box Power Options Properties. In the Alarm tab, you can check the boxes to either be alerted when your battery is low and / or when the battery is critical. You can even use the control slider to make your own determination of what is low and what is critical. Then you can click on Alarm Action to tell your computer to, for example, sound an alarm or go into standby mode when those moments are reached.

On the Advanced tab, you can choose what you want your laptop to do when you close the lid. You can choose to go into standby, hibernation, or even do nothing if desired. You can also choose what they would like the team then when you hit the power button.

If you are interested in using his laptop's Hibernation feature you should check box on the tab that says Enable hibernation hibernation.

Disable wireless network card

Your wireless card can also be a burden on the resources of your battery, so turn it off if not required. (No need, of course, on a plane, for example.) If your laptop has a wireless card, simply take it out. If your laptop has wireless built in, you can disable Windows XP, click "Start" and go to Control Panel. In Category View, click Network and Internet Connections, then Network Connections. In Classic view, click Network Connections. Once there, right click on the wireless connection you are using, and click Disable. You can also disable your wireless network card via Device Manager. Right-click My Computer and left click on Properties. Click the Hardware tab and then click the button Device Manager. Then click the small black cross next to where it says network adapter. Find the wireless network adapter, right click on it and left click on Disable.

You can also left click on Properties instead (after you right-click on the adapter network), click the Power Management tab and check the box that says "Allow the computer to turn off this device to save power.

Some newer laptops with Intel Mobile Pentium ® is a button somewhere on the laptop itself, for example in the front, so you can convert easily or disable your wireless network. You may have to check your laptop manual to see if you have a button and if so, where found.

CPU Throttling

The Mobile Intel Pentium ® Laptops also sport a feature known as CPU throttling (and the name of Intel SpeedStep ™), which actually slows the processor when running on the battery. When connected to AC, your processor runs at full speed. But when you unplug the cable, switch to a lower gear. A processor operates at a speed less and less voltage saves your battery until the juice more.

So now we have a set of tools to implement to save precious energy from your computer. But perhaps instead on that next long distance flight, you might want to think ahead and reserve a seat with an outlet.
