Maximize Your Laptop Battery

If you take the time to make a few adjustments to your laptop, while keeping battery conservation at the forefront of your mind, you can effectively extend the power of the battery's life and, until you can plug in your computer, avoid losing the use of it.

 Click on low-power settings, such as "sleep," "standby" or "suspend" when you close your computer, but don't want to completely shut it down. This works two-fold. It gives you the opportunity to resume your work quickly while saving power. "Hibernate" uses less power than "sleep." It shuts your computer down and saves everything to the hard drive. When you resume power, your desktop is exactly as you left it, saving you time.

  Remove any USB devices or PC cards you don't need to conserve battery power. If your computer uses a wireless card, remove it when you don't need the connection. Disable any devices, via your computer's device manager, that you aren't using, such as your modem, network card or DVD/CD-ROM drive.

  Dim the screen on your laptop. Check the keyboard for function keys that will allow you to do so, or consult your user's manual. A dim screen uses less battery power than a bright one. Set your computer screen to go blank after a certain period of time, such as five minutes of inactivity. If you are interrupted while working for longer than the period of time you select, the blank screen will appear and save power.

 Prioritise your work; if you don't have to multi task don't. Consider switching off the autosave functions in MS Word or other applications. They are great but as they keep saving at regular intervals, they make your hard disk work harder, eating up battery power. That said, we should add a word of warning: when your battery is low switch autosave back on so you don't lose work if the computer unexpectedly switches off when the battery goes flat.

Unplug unnecessary devices such as additional speakers, or things like DVD and hard disks that take power via USB from the laptop. Consider changing your screen resolution and brightness. The brighter the screen appears, the more electricity it is consuming. Work from your hard disk rather than the CD or DVD drive. On some laptops, you can even remove the optical drive.

  In this feature we'll give you hints and tips on how you can prolong the running time of your notebook's battery. On many netbooks, there may be fewer options to tweak, but you can still follow our tips to make your battery last longer.

A hybrid battery pack Squeezes More Miles Out of Gasoline

A hybrid battery pack combines an ultracapacitor, which bottles up a quick burst of power, with a conventional battery, which can store more energy.IoxusA hybrid battery pack combines an ultracapacitor, which bottles up a quick burst of energy, with a conventional battery, which can store more energy. 

On Monday I wrote about odd new devices that would help big trucks meet new standards for heavy vehicles' fuel economy that are expected to be issued any day now. Also expected imminently were new corporate average fuel economy (known as CAFE) standards for cars, pickups, minivans and S.U.V.'s.

Rules announced last year already required that cars get an average of 35.5 miles per gallon starting in the 2016 model year. And as with trucks, a variety of battery technologies are emerging from the labs to improve fuel economy.

For cars, one obvious strategy is to have the engine shut down whenever the car stops at a red light. That requires quickly starting the engine when the light turns green, and that means frequent discharges of large amounts of current.

This is a challenge for most batteries on the market. Most lithium-ion batteries can store lots of energy but cannot charge or discharge quickly. Lead-acid batteries can deliver the required amount of power, but not thousands of times over the lifetime of a car.

Ioxus, a start-up company in Oneonta, N.Y., says it is working with several automakers on testing a hybrid battery. The battery marries a device called an ultracapacitor, which bottles up something like a lightning bolt of power, with a conventional battery, which can store more energy but absorbs and discharges it at a slower rate.

The company is not alone in this area. AFS Trinity built an entire vehicle to demonstrate that ultracapacitors paired with batteries could meet the highly variable needs of a battery pack, both holding a lot of energy and accepting or discharging it quickly. The concept has not entered the commercial mainstream yet, though.

Ioxus's device involves using a carbon coating on a sheet of aluminum. One gram of the carbon, spread over a square meter of aluminum, has the surface area of a football field because it has so many pockets and pits, according to Mark E. McGough, the company's chief executive.

The technology has a second possible use on the road: in hybrid cars, for which power steering is a problem. In ordinary cars, the steering is powered by a belt connected to the continuously running engine. In a hybrid, of course, the engine is not always running. The solution is an electrically driven power steering system in place of the ordinary hydraulically driven one. The capacitor can run that electric system, Mr. McGough said.

This product is already embedded in a completely different part of the energy world: wind power. In case of a big wind storm, wind turbines need a way to change the orientation of their blades so they do not catch the wind and break. The blades are quite heavy, and pivoting them requires a big short burst of energy that they can call on even if there is a power failure. So some have turned to Ioxus's ultracapacitors, Mr. McGough said.
