Maximize battery life

Maybe you use your laptop for a long time,but maybe you don't know how to make your battery have a long life.Just like HP Pavilion dv4 Battery.

One surefire way to ensure that your laptop is always ready for action is to plug it into an AC outlet whenever possible. Keeping the machine fully charged makes it far more likely that you will always have the juice you need to complete your work. Purchase at least one extra AC adapter, so you’ll always have one in your office and one in your laptop bag for travel. If you work at home frequently, consider buying a third adapter to leave there.
"Terminate the offending process by right-clicking it and selecting ‘Kill Process’."

A common misconception about laptops is that leaving the system plugged into AC power continuously will overcharge or shorten the life of its battery. Given that the lithium cells used in modern laptops will either catch fire or explode if overcharged, this is obviously not true. Lithium ion batteries stop charging once they reach full capacity, and keeping the battery charged reduces wear and tear on the power source, lengthening its useful life span.

Modern displays with LED backlights are a major improvement over the CCFL (cold cathode fluorescent tube) backlit displays of yesteryear, in terms of both picture quality and power efficiency. Still, a laptop’s display claims a significant percentage of the power that the system consumes. As such, keeping the screen backlight low can increase your laptop’s run time noticeably. You should also take care in choosing where you work: A low backlight setting will be far more comfortable in a café with soft lighting than in a brightly lit room. Another way to reduce the power the display consumes is to tweak the automatic backlight controls in Windows. Open Control Panel, choose Hardware and Sound > Power Options, and click Change plan settings for the active power plan. Choosing an aggressive timeout of 1 to 3 minutes under the ‘Dim the display’ and ‘Turn off the display’ options while the machine is operating on battery power will eke out more battery life by dimming or switching off the screen after the specified amount of inactivity. You can also click the Change advanced power settings option to set the level of brightness when the laptop is in the dimmed state. Maybe you can test the battery APPLE A1175.

One culprit often responsible for draining the battery ahead of its time is the presence of errant software applications that suck up disproportionate processor cycles. Unnecessary utilities running in the background, or an app that is hanging, can also cause this effect. Web browsers are particularly prone to the latter problem, due to the multiple plug-ins, rendering engines, and scripting engines embedded within them.  Modern CPUs save power by dynamically scaling back their clock speed to the minimum possible, but they can do so only when apps aren’t active. If you fail to deal with rogue apps, they will not only drain battery power—they might also slow down your entire system. One clue to the existence of an errant app is if your laptop fan frequently kicks into high gear when the machine should be idle.

Resolving the problem is relatively straightforward: Press the Ctrl-Alt-Delete key combination, launch Windows Task Manager, and use it to identify processes that are showing unexplained high utilization. If a program won’t exit normally, terminate the offending process by right-clicking it and selecting Kill Process. For Web browsers, shutting off all instances usually works. Should all else fail, perform a system restart.

Errant apps aside, applications that make intensive use of the processor or network should remain closed when your laptop isn’t plugged in. Peer-to-peer software such as BitTorrent clients and computationally intensive applications such as distributed-computing projects are out. You can also confirm that Windows Update and other software updaters are not attempting to download large software patches.Disabling automatic Windows Update functions outright is too draconian (particularly if you forget to reinstate the feature later), but periodically checking on your network usage for unexplained spikes will allow you to identify and stop large file transfers before they gobble up precious minutes of battery life. If you have a sony laptop,the VGP-BPS27 Battery is good.

You can disable unneeded hardware devices or ports to squeeze out a few more minutes of power, although this option isn’t possible with every laptop. Start by disabling unneeded wireless capabilities, such as built-in data modems and Wi-Fi and Bluetooth radios (many laptops have hardware switches for this purpose).The optical-disc drive is another power guzzler that can drain batteries fast, so don’t leave a DVD or Blu-ray disc in the drive if you don’t need it. Finally, many laptops these days come with backlit keyboards; these are great when you’re in a dark environment, but you can save precious power by doing without the feature when your laptop is running on battery power.

If your battery have already can't support your laptop for long time,you should have a new one or buy a new charger.You can go http://www.batteriescenter.com.au/.

The lenovo touch notebook

With the popularity of Windows 8, users start to use finger to a new way of manipulation. Now the mainstream mobile devices, mobile phones, tablets and laptops are inseparable with the touch operation, even the user will use fingers to click as soon as they see the screen, it's enough to explain touch mode already allows users to form a habit.

New notebook market  has been pre-loaded with Windows 8 this year, and the vast majority of laptop support touch operation, users click on finger operation also gradually replaced the touchpad and the mouse, in web browsing, query information, or see high-definition video, use finger sliding operate more quickly and directly touch the notebook in future will be more and more popular, used in the share will be accompanied by the user and climbing.

Lenovo is active in touch laptop, before the launch of the Yoga series are welcome, and 360 ° freedom turn also is deeply rooted in the hearts of the people, the concept of 360 ° rotating screen set to make a regular laptop computer become more flexible. In the second half of this year lenovo launched a Flex 14, a touch of notebook continue the Yoga design essence, flexible manipulation of the natural as a whole.

Edit after a week of trial experience, found that Windows 8 touch way is very convenient, especially the support way of touch screen, no different finger operation and tablets, and the advantage of large size laptop screen is more obvious. With Windows 8 app store constantly enrich, users can download software is also increasing in number. Personally, the following 12 of the latest application of editors are often used to, if your touch laptop haven't installed the software, might as well can try. In many cases, the touchscreen to provide help or good.

Samsung GALAXY Round

Flexible screens samsung GALAXY Round attract the attention of a lot of people, but if you plan to purchase the machine in the future, may be more difficult. Of course, this is not a samsung to make what hunger marketing,DELL XPS M1330 battery but it is just a prototype to test the product, and only limited release in Korea market, launched the international version is unlikely.

According to focus on samsung overseas websites Sammobile of information disclosure, according to the samsung GALAXY Round will be a prototype to test the product, will not be mass production and large market share, even in Korea is limited, so future launch international version is unlikely. In fact, this is not a samsung to small range of small-scale production, for the first time. Such as in the past, samsung launched a models for SCH - W850 models, its main function is to test the latest AMOLED technology at that time.DELL PT6V8 Battery

In addition, there are some relatively well known to us the samsung GALAXY SII HD LTE, is used to test the HD AMOLED technology.MEDION MD97460 Battery As a result, the samsung GALAXY Round appeared from the previous model, should also specifically for test and flexible screen technology, could not be sold in overseas market.

5.7 in the flexible screens
Obviously, if the news is true, it means the samsung GALAXY of Round launched in fact more is for head. Because after it emerged that LG will be released in November, the first curved surface screen smartphone G - Flex. From the unique features of this machine is equipped with flexible screen at the same time, also seems to be more a gimmick, and imagination have a larger gap.APPLE A1405 Battery
In spite of this, the samsung GALAXY Round or can use its surface features make the user more comfortable while talking on the phone, and at the time of horizontal mobile phone, the user press the phone side, mobile phone screen will light up automatically, display unread messages, time and other information.

For millions of the won
Samsung GALAXY Round the other configuration with samsung GALAXY Note 3 almost don't have much difference, is equipped with a 5.7 -inch flexible screen also supports FHD full hd resolution, and is equipped with 3 gb of memory, and 2.3 GHz qualcomm Xiao dragon 800 quad-core processors, Android4.3 system and a built-in carrying 13 million pixels in the main camera. However, it did not provide S - Pen, and equipped with a 2800 mah battery only, life wants relatively a few less.

High-energy battery in the future

Last month Panasonic announced two high-energy batteries(Acer Aspire One 532h Battery,Acer Aspire One D250 Series Battery) for electric vehicles. These new batteries store as much as 30 percent more energy than its previous lithium-ion batteries, and this increased storage could, in theory, increase a vehicle’s range by a similar amount, thereby addressing one of the main problems with electric cars. Tesla’s Roadster currently has a range of 244 miles and takes three and a half hours to charge with a special charger.

The other major challenge with electric vehicles is the cost of the battery packs. Tesla isn’t announcing the potential cost savings with future batteries, but JB Straubel, Tesla Motor’s chief technology officer, says  costs have been steadily declining at about 8 percent a year.

Tesla plans to incorporate Panasonic’s cells into its battery packs, and will work with Panasonic to develop cells fine-tuned for use in cars, Straubel says. To do this, Tesla will draw on data gathered from the 1,000 cars it has made so far, which have been driven for over a million miles. Tesla currently gets its batteries from a variety of manufacturers.

Those driving Tesla cars won’t immediately see the added range from the new high-energy battery cells, Straubel says, since there is a lengthy process for validating the performance of new cells. What’s more, the actual range increases can vary. (For example, electronic controls keep a battery from completely discharging to help improve safety and reliability–complete discharges can harm some DELL Studio 1747 Battery materials. The way the battery is controlled depends upon its chemistry and other details of the cell design.)

One of the new cells in particular will require extensive testing, since it relies on silicon-based electrodes. In theory, silicon electrodes can hold much more energy than the carbon electrodes they replace, dell studio 1558 battery, but silicon electrodes tend to swell and break apart. They’ll need to be tested to make sure these problems have been overcome.

The Difference Between 6 Cell & 12 Cell Laptop Batteries

To best understand the differences between 6-cell and 12-cell batteries, you should have a basic understanding of how batteries work. A cell is simply a battery in its simplest form. The cell consists of three main parts: an anode and a cathode, which are separated by an electrolyte. In a standard Lithium-Ion battery, a reaction at the anode turns Lithium into a cation, which also creates a free electron. The cations move through the electrolyte to the cathode, while the electrons move through the wire to the cathode, where the ion and electrons will meet up again. Any motor positioned along the wire can use the electrons for power. Batteries are made up of a number of these cells, along with a small control board that ensures the battery is operating safely. Laptop batteries are rechargeable, which simply means that the chemical reaction can be reversed,moving the Lithium atoms back to the anode.

Power Differences

Each cell in a battery can be positioned in a series with, or parallel to, the the other cells. When the cells are aligned in a series, the voltages are added together allowing 3.6 Volt lithium-ion cells to be part of a battery that has a much higher voltage. When the cells are aligned parallel to each other, the voltage isn't added together, but the overall capacity of the battery is increased. Because of this, a 12-cell battery has twice the capacity of a 6-cell battery, while maintaining the same amount of voltage.

Size and Weight Differences

Because the 12-cell battery has six cells that a 6-cell battery does not have, the battery does have some physical differences. First, the 12-cell battery is twice the size of a 6-cell battery, making it bulge out from the bottom of many kinds of laptops. This isn't always a bad thing, as the extra space it creates will help keep the laptop running cooler when you use it on a desk or table. Second, the 12-cell battery will have twice the weight of a 6-cell battery. The battery is normally one of the heaviest components in a laptop, so this consideration should not be taken lightly if you plan on carrying the laptop around.

It takes extra components to create a 12-cell battery, as compared to a 6-cell one, so there is naturally a higher cost associated with the 12-cell battery. Additionally, 12-cell batteries cost more due to the extra capacity being regarded as superior to the 12-cell battery's drawbacks. While prices will vary wildly based on the battery's manufacturer and model, the 12-cell is rarely priced at more than twice the price of the 6-cell, making it a judgement call for the individual whether or not the 12-cell battery is worth the extra cost.

Repair Laptop Battery Chargers

Sometimes maybe your laptop battery can not charging,the battery is good.So you need to check the charger,A laptop battery charger often becomes worn because it is constantly being pulled and plugged in and out of the laptop and an electric outlet. Without the charger, you won't be able to use the laptop when the battery dies. Laptop battery charger repair can be done if you are adept in repairing computer parts.Then there are some advice to repair it.

Shut down the computer and pull out the charger from the laptop and the electric outlet.

Plug the soldering iron in an electric outlet and turn it on. Allow it to reach 80 degrees Celsius (176 degrees Fahrenheit).

Remove the screws that hold the base of the computer to the chassis of the computer. Use a screwdriver to take out the screws. Mark each screw so you know exactly where to put them back.

Remove the laptop motherboard and carefully blow off any dust. Place the motherboard on an antistatic mat.

Look for the power jack, which is usually to be found at top right hand corner of the motherboard. It is a small, silver-color piece. Check if the soldering on the jack is broken or misaligned.

Place the de-soldering pump on the soldering and start removing all the old solder by holding the iron on the solder until it runs into the pump.

Detach the contacts from the jack on the motherboard by removing the old solder as you did in Step 6. Once all the solder is removed, gently remove the jack off from the motherboard.

Observe the receptacle on the circuit board that should be clearly visible with the jack out of the way. Remove any flux, debris or dirt around the receptacle using a small brush or a toothbrush.

Clean out the jack using a small eyeglass screwdriver or a tiny penknife. Solder the contacts using as little solder as possible.

Solder the input jack back on to the motherboard. Resolder any contacts you have unsoldered. When the solder is dry, re-assemble the computer base onto the chassis placing each screw right where it was removed.

The most simple advice is you need a new charger,you can find it on http://www.batteriescenter.com.au/.

Optimize Your laptop Battery Performance

In the process of using laptops at daily times, the battery will continue to loss, how to make a longer battery life?We need to maintain it regularly, there will be some way below to protuct it.

If you are going to take a lot of time without using the battery for Dell Inspiron 1564 and your laptop, you need to store it correctly. The MEDION MD-97460 battery is made of special cells that tend to discharge even when the machine is not running. This ultimately results to complete discharge which can destroy the battery. You should charge the battery fully and store it separately from the laptop in a cool and dry area.

Make sure to condition the battery once a month
Conditioning the APPLE A1405 battery is important in increasing its performance especially working off the mains. Conditioning involves complete discharge of the battery by leaving it on until it dies off. Then, charge it to full capacity before starting the laptop. This method is also effective in telling how your battery for APPLE A1405 battery is aging and wearing down in order note the right time to go for replacement. Make sure to only do this once every month because frequent conditioning can stress the cells.

Handle battery replacements and new ones with great care
When you purchase a new battery for Asus K52J battery, it is important to take good initial care to avoid cells and ions destruction. You are advised to charge it fully before starting to use it or putting the laptop on. When you put the battery in the laptop and plug it for the first time, it indicates to be fully charged within a few minutes. You should remove the battery from the laptop and let it settle for 20-30 minutes and the resume charging.

Do not leave the battery plugged on the mains
As you charge the laptop using your Asus K52J battery, it tends to get hot over time. This heat can reach levels that burn the adapter circuit. The charging system also causes overheating of the battery because of continued wearing and tearing away. You should therefore only charge the battery when you are around because you can note when the adapter is hot or laptop temperatures goes too high.

The common sense about laptop battery

We can see the Voltage and Capacity on the laptop battery.Such as Laptop Battery APPLE A1417.The voltage is 10.95V.The capacity is 95WH/8460MAH.That is just the input voltage. The 100-240V says the power supply is a universal supply that will automatically adjust to the input (wall) voltage, depending on what your country uses. And the 1.2A is how much current it may draw. If the output voltage is the same, the 1.2A vs the 1.5A means it will take longer to fully charge your battery. It could however, be a bit stressed if you use the notebook while a deeply discharged battery is being charged (batteries draw the most current when deeply discharged).

However, it is CRITICAL the output voltage and plug configuration are the same. So that is where you need to concentrate your research.Think of a 12V car battery. If you connect a 9V charger to it, the battery will never fully charge. If you connect a 24V battery to it, the battery will likely over charge, and may catch fire. And if you connect the positive lead of the charger to the negative post on the battery, sparks WILL fly!

The current (output amperage) does not really matter for charging a battery. Low current will "trickle" charge - it will take a long time, but will fully charge. High current will "quick" charge but because batteries will only take what they need, there really is no such thing as too much charging current.Plug configuration matters because there are many different types. And even the same type plugs may be wired with different polarities with + on the center pin with this plug, and - on the center pin with that plug.

What you could do is what I did for my toolbag when I make "housecalls" is get a Universal Automatic Power Supply. Then all I have to do is make sure I select the correct connector and the "intelligence" in the supply determines the correct voltage and plug polarity. This Rosewill is a bit more expensive than most universal supplies, but it supports ASUS, ACER, Sony, DELTA, IBM, DELL, Compaq, HP, NEC, Lite on, Toshiba, Gateway, Delta, and Sharp notebooks (and probably many more), and I don't have to fiddle with output voltage jumpers or switches.
