Ever been on a long flight, ready to hunker down and get some work done, only to discover that your notebook's battery is plunging toward the red zone an hour after takeoff? So have we. That's why we've gathered these simple tips that will preserve your notebook's juice and boost your productivity. Read them now. You'll thank yourself later.Battery for HP Pavilion dv5t-1000

1. Sleep Is Good
Use the operating system's power-management features (in Windows XP, under Power Options in the Control Panel; or in Vista, under Mobile PC in the Control Panel) to set aggressive targets for when the display will go dark (say, after five minutes of inactivity) and when the machine will slip into sleep mode (no longer than ten minutes of inactivity). And if you can spare the extra time it takes for the machine to resume, set the PC to hibernate, not just sleep, when you close the lid.Battery for HP Pavilion dv5z

2. Don't Be Performance Hungry
Unless you're running high-order mathematical calculations on that long plane ride, chances are you don't need all the processing power your CPU is capable of giving. So in Vista, select the "Power saver" power plan (found in the Control Panel, in the Power Options section) to extend battery life when on DC power, and leave the 3D gaming for when you're near an AC outlet.Battery for HP Pavilion dv6

3. Dim the Lights
Turn down the brightness of the LCD panel (via the Function-key combo, or in the Control Panel's Display Settings dialog) to the lowest level you can tolerate. The backlight sucks power like the Rockefeller Center Christmas tree.

4. Banish Non-Essential Components
When you aren't actively using the Wi-Fi, Bluetooth, and IR radios, turn them off (via the hard switch, if your PC has it, or in the appropriate utility set), so they don't trickle you dry trying to connect. Also, use USB-attached devices only when absolutely necessary. They aren't getting their power from positive ions in the air, you know.Battery for HP Pavilion dv6t

5. Watch Scheduled Tasks
Be sure that your periodic virus scan is set to a time when you're usually plugged in; running a full-disk virus check keeps the hard drive and CPU fully engaged for the better part of an hour.

6. Lay Off the Multimedia
A little in-flight music is nice while you construct that PowerPoint presentation, but streaming music from your hard drive (or playing a CD) means the disk (or disc) is always spinning.

7. Get More Juice
Let everyone else fight over that free AC outlet. Designed to sit underneath your notebook, the APC Universal Notebook Battery 70 ($149; www.apcc.com) can provide up to six hours of endurance using its lithium polymer technology. It comes with a variety of notebook tips and features selectable output voltages. The unit adds 1.8 pounds to your carry-on, but it's better than having your laptop run out of gas midflight.he year 2006 marked a fundamental shift in PC hardware sales as laptop computers (also called "notebooks") outsold desktop PCs for the very first time. As society becomes more mobile, laptops become ever-more powerful, portable, and affordable, and as wireless networks become ubiquitous, this trend will continue. Battery for HP Pavilion dv6t-1000

Obviously, the primary advantage of laptops is mobility. Naturally, however, laptops need power to run on. Even though electrical outlets are plentiful and can be found nearly everywhere, there are times when we have to resort to using the laptop's Battery for HP Pavilion dv6z - airplane trips, meetings, etc. I have also seen sudden power failures when I could have lost all my work had the laptop not had a charged 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. We can start by discussing what a battery is, how it works, and the different types of batteries in use today.Battery for HP Pavilion HDX16t

In simple terms, a Battery for HP Pavilion dm4 is chemical energy stored in a container. The chemical energy is then converted to electrical form. A battery has two terminals, negative and positive, that must be connected for the current to flow. This connection is usually provided by a liquid or solid electrolyte that is a conductor; it has the ability to transfer current. Cathode and anode are two electrodes, an electrical conductor that makes contact with the metallic part of a circuit, present in a Battery for HP Pavilion dm4t . Current flows from the cathode to anode inside the cell or device.In contemporary portable electronic devices, especially given environmental concerns, batteries must not only store energy in a compact form, they must be rechargeable. Battery for HP G62

Batteries are usually named based on the metal used to make either the electrodes or the electrolyte. A lithium-ion battery (LIon) has a lithium anode, a zinc-carbon Battery for HP G62x has a zinc anode, and a nickel-metal hydride battery (NiMH) or a nickel-cadmium battery (NiCD) has a hydrogen-absorbing alloy for the anode.Early rechargeable batteries were composed of Nickel-Cadmium (or "NiCad"). NiCads were great because they were rechargeable, but early NiCads held comparatively small charges as well as suffering from "Memory Effect" - if the battery was only partially drained and then recharged, it lost its ability to be fully recharged.Most portable devices these days use Lithium-Ion Battery for HP G72 . Lithium is the lightest metal and the one with the highest stored ("potential") electrochemical energy. These qualities, along with the fact they do not contain poisonous metals (such as cadmium) make lithium-based batteries the most widely used to power portable devices such as laptops.Battery for HP G72T
