find more mystery of batteries

the article from : http://www.shoppingmag.net/2010/the-mystery-of-batteries-05-06

Batteries are filled with mystery, and for good reason¡ªeveryone’s use of their battery is different, and some batteries are built differently. Some laptop owners still get decent life out of their three-year-old standard latitude d505 battery , while others can barely live through a rapid un-packing of their charging cord once their charge icon turns red.

To thicken this mysterious brew of battery knowledge, modern operating systems are pushing the use of “Sleep”¡ªalso labled “Suspend” or “Standby”¡ªover the “Shutdown” we’ve come to know more of latitude d630 battery . It doesn’t draw nearly the same kind of power as a fully operational computer, but it does allow you to start your system back up and get back to the things you had open in a few seconds on a relatively new system, rather than wait for everything to get back to stability.

By dividing the milliwatt-hours by the voltage of the latitude d610 battery computer they were measured from, though, you get the milliampere hours. Voltage varies in a device¡ªbetween 11.2 volts on a Sony Vaio and 12.4 volts on a ThinkPad at its peak¡ªso the lowest voltage was used when there were discrepancies; we figured we’d tend toward a worst-case battery use scenario.

Windows Vista has sleep as its default action on the “Power” button, but changed it back in Windows 7, likely due to (valid) user complaints. And the huge, 7-8-hour latitude d830 battery being packed into MacBooks are certainly due in some part to the preference of many users to close the lid rather than shut down.

We used two free battery monitoring utilities that offer extensive power details: BatteryCare for Windows, and coconutBattery for Mac. Both are great applications to grab if you’re interested in how much your battery holds, how much it used to hold when it came out of the factory, and other data points.

Your mileage will vary with hibernation, though¡ªI’ve found it not as reliable, and slow, on my main laptop.In all cases, actively open programs were shut down before a sleep or shutdown. latitude d600 battery Batteries lose charge even when they’re not doing anything¡ªjust sitting in a shut-off computer¡ªso the strain of shutting down and starting up a system doesn’t make it an obvious choice, as you’ll see below.

Changing your laptop battery

The piecture Via battery blog

Changing a laptop battery is a relatively simple process. Normally, a new lithium-ion laptop battery will give satisfactory performance through approximately 500 charge-recharge cycles of use.

The first laptops will run on standard AA batteries. However, it consumes so much power that could run on a set of batteries for only a few hours. The first commercial notebook computers compatible with IBM were small and light enough to be carried in a backpack, and could run on lead acid batteries, the type used in automobiles.

The latest generations of batteries used in laptops are called “smart batteries. This is because the battery’s ability to communicate with the laptop user. Unfortunately, the definition of a smart battery” is not universal, but varies among different manufacturers and regulatory authorities. Some vendors call their batteries ’smart’ because their XPS M1310 battery incorporate a preprogrammed chip that sets the charger as standard requirements.

Most “smart” battery chargers are controlled by the parameters of chemical cells. Once the chemical cell has degraded, the laptop battery needs to be changed. In some cases, the chemistry of the battery can be fully restored, but the fuel gauge may be inaccurate or other data may be corrupted. In these cases, although the digital readout becomes inaccurate due to a malfunction, the battery fully charged yet and can operate for some time.

At the end of its useful life, reversible chemical processes inside a XPS M1710 battery degrades considerably. This leads to a state where the battery can not power the laptop unless it is connected to the main 110-volt source through an adopter. This means that effectively turns the laptop on a desk.

When it comes time to replace your laptop battery is better to buy a replacement Dell Latitude D820 Battery for the agency, which sold the laptop. It is also advisable to ask suppliers of batteries to replace the battery, it would be more familiar with the proceedings.

Customer Review

“I bought a second laptop battery as I am often at client sites and need the time 2 batteries will give me. The original battery (18 mos old) is starting to show some signs of reduced life. The backup (1 year old) still gives me 2-3 hours. I make it a point to unplug my machine and cycle the batteries a couple of time a week. There is no faster way to kill a battery than to leave it plugged “for 99.5% of the time” as some of the reviewers admit doing. I learned that lesson on previous machines. There’s nothing wrong with either of Pavilion DV2000 batteries pavilion DV6000 battery I have - I am very satisfied. I think the problem with the other reviews is user error. BTW - you should expect to replace the battery every 18 months - shorter if you abuse it by leaving it plugged in. I’ve been using laptops exclusively since 1995 and I have never had a battery that didn’t completely die within 2 years. That’s just how they work. Cycle the battery all the way to 0 at least once a week. That will give you the maximum life from it. These are no worse than any other battery.”

“I have had my dv9000 laptop for 2 years, this past December. So that is roughly 26 months now and I leave my laptop battery in my computer ALL the time and it still runs. It all depends on what power setting I am using. On high performance, the battery will still last about 45 min to an hour and on power saver it will last roughly 2-2 1/2 hours. I try to take care of my computer, but it has over heated on numerous occasions (all my fault for not using a cooling pad) and the battery is still going. (Wish HP had better design to cool the laptops) To bad the replacement batteries are so expensive.”

“My business partner bought the Pavillion DV9000 battery as more useful office computers for the company in 2004. The HP laptops have been wonderful. The first battery that came with the laptop lasted about two years. The second about 18 months. The third barely made it through a year. I have had to park the laptop because it is eating up our media budget. The other laptop does not use batteries as quickly, but it is not used as often. No, the laptop does not stay plugged in all the time. It stays in its case, battery in a separate compartment. I was told that is the best way to store the laptop. So today, I am finally ordering battery number 4. At these battery replacement prices, we may have to go back to another brand, which I liked much less. What a shame.”

“Both the original battery and a replacement spare battery only lasted about 1 year before reduced run time made them only useful for moving from one AC outlet to another. I’m ordering another with hopes that the battery has been improved. I think my mistake has been to leave the battery in the computer and on AC most of the time. HP should have software on the computer to prevent destruction of the battery due to overcharging.”

Make your laptop battery last longer

The laptops allow us to work anywhere, even use that spare time we travel to advance some work, but sometimes we do not have a power source nearby and we must make use of laptop battery which. .. is not eternal!. With these tips you can save energy in your laptop and make your battery last longer.

Unplug everything that did not use.

all devices connected to your laptop consume energy, but the consumption is very low, if we can save power disconnected:
• Unplug any device connected to the USB ports you’re not using (pendrive, mini mouse, etc).
• Remove any DVD or CD you have on the reader, since these can be turned regularly to read the disc and this consumes much VGP-BPS10 energy.
• If you do not use, turn off the Bluetooth and Wireless adapter.
• Turn off the LEDs on your laptop (some laptops have that option).

Use only the necessary programs.
Each program opened consume CPU resources and in turn it uses energy, which is why it is advisable to only have open the programs we’re using. Even we can close those programs that are in the system tray and run in the background that using your VGP-BPS10/S power .

By reducing the amount of free memory processes also prevent Windows from RaM and use the hard disk virtual memory, which will help us save VGP-BPS10/B energy, since the disc has a high consumption.

The state of your PC to their use.
When you use your laptop for a few minutes or put it in Stand By Sleep, and when you do not have to use for a while longer place your laptop in hibernate mode.

Monitor ONSUMPTION

Know Your Laptop Battery

When given this question to any user of the laptop or notebook, they will get confused. This happens to me once when someone asks me about the battery of my laptop. As you can see, before replacing the laptop battery is very important to know a little about the field again in the first place. There are several types of laptop batteries that I will share in this post.

The article Via Battery blog

The types of laptop batteries:

1. Alkaline - This is a common battery around, but only a few use laptops and the ruling on alkaline Dell Inspiron 6400 Battery is not rechargeable. You have to shoot once to deflate.

2. Lead Acid - One of the most common uses of this kind is for laptops. It is durable, resistant and rechargeable, but unfortunately the Dell Inspiron 640m Battery is heavy and full of lead: P.

3. Lithium-Ion - The type of Vostro 1510 battery that you want to have for your laptop. The quick-charge effect is good for users moving (no need to wait a while for the battery is fully charged.) It is also environmentally friendly as well.

4. Nickel Cadmium - Ni-Cd is one of the oldest types and improved performance of rechargeable Vostro 1310 battery , but has a serious problem. After prolonged use (several years), the battery will be affected by the dreaded memory effect. This means that the use of battery life deteriorates over time.

5. Nickel Metal Hydride - Ni-MH is considered the successor to the Ni-Cd batteries, but unfortunately, the dreaded memory effect is as bad as well. However, comparison of the Ni-Cd and NiMH batteries, it lasts longer compared to its predecessor.

The chances of using lithium-ion Vostro 1520 battery is 99% (that is if you are using the new breed of laptops:)). Just check the abbreviation says Lion or Li-Ion batteries in laptop battery label. There are still some laptops that use Ni-MH batteries these days and you may want to check with the manufacturer if you can make an update of Ni-MH Li-Ion. The unauthorized use of batteries could lead to dire consequences …. so do be very careful about this. If you have a larger budget you might want to check the SMART batteries. It has a power management circuit and also tells the user which is the current condition of the battery.

free software package for Mac computer users

Amazon introduced a free software package Thursday that gives Mac computer users access to the online retailer’s Kindle e-book store in more than 100 countries of Dell inspiron 1300 battery . Called Kindle for Mac, the beta e-reader completes Amazon’s goal of offering consumers access to e-books and other digital content across a wide spectrum of electronic devices .

Kindle books can now be read on dedicated Kindle and Kindle DX devices, BlackBerry handsets, and PCs, as well as Apple’s Mac, iPhone and iPod touch , Amazon said for Dell inspiron 1501 battery . Moreover, the company’s e-reader software is expected to work on Apple’s forthcoming iPad .

The system requirements for Kindle for Mac include a Mac computer with a 500-MHz Intel processor or faster, a minimum of 512MB of RAM, and 100MB of available disk space for iBook G4 12 inch Battery, . The beta release, which is compatible with Mac OS X 10.5 (Leopard) and 10.6 (Snow Leopard), also requires a minimum screen resolution of 800×600 pixels.

Just like Amazon’s other e-reader platforms, Kindle for Mac integrates the company’s homegrown Whispersync technology, which automatically saves and synchronizes bookmarks — and the last page read — across multiple Toshiba PA3399U-2BRS battery devices . As a result, customers who begin reading an e-book on any compatible device will never lose their place when they switch to another platform.

With Kindle for Mac, readers will be able to choose from 10 different font sizes as well as adjust words on a per-line basis of Sony VGP-BPS8 battery . The new beta release also will enable users to view notes and highlights previously marked on the Kindle, Kindle DX, and Kindle for iPhone platforms.

Amazon’s launch of Kindle for Mac in advance of the iPad’s rollout next month enables the online retailer to claim full compatibility across the most popular products in Apple’s portfolio of Dell inspiron 1520 battery . Though Apple has been touting the iPad as a device to use alongside a PC and the iPhone, iPad customers must use a cable to sync digital content with a PC or Mac, noted Ian Fogg, a principal analyst at Forrester Research .

“While the iPad has genuinely innovative software and hardware, Apple has done little new to make the device easy to use in tandem with existing devices, beyond what is already in the iPhone of MacBook Pro 17 inch Battery ,” Fogg wrote in a blog.

By contrast, Amazon’s Whispersync technology maintains a person’s reading position automatically between multiple devices running Kindle apps, Fogg noted. “The same issue hits multiple areas on iPad, from game scores and progress of Dell inspiron 1100 battery , the reading position on Apple’s own e-books, and the preferences of apps downloaded from Apple’s App Store , e-mail, calendar and contacts,” Fogg observed.

MySpace Will put as much weight on games

“We initially embraced games a few years back with a gaming platform, but at the end of the day it was fairly isolated in certain parts of MySpace,” MySpace co-president Mike Jones told AFP at a Game Developers Conference here for Sony VGP-BPS9/B battery .”MySpace is going to put as much weight behind games as we put behind music.”

MySpace sees its prime demographic as Internet users between the ages of 14 and 36.The social network claims more than 100 million users, about 30 percent of whom rack up about a total of a billion minutes of online game play each month for Sony VGP-BPS8A battery . MySpace is striving to reclaim lost glory and expand its popularity in a social networking world dominated by Facebook, which boasts more than 400 million users.

“MySpace is not falling off a cliff but, at the same time, they see gaming as a ladder to find their way into more people’s lives and get back on the radar ,” said analyst Scott Steinberg, author of Get Rich Playing Games of Sony VGP-BPS9A battery .After being eclipsed by online social networking star Facebook , MySpace made itself into an Internet community for people who make or love music.

“Facebook has left them crowded out. At the edge of the spotlight is still out of the light.”MySpace unveiled a new games gallery at myspace games and began automatically recommending games to new members along with song and friend suggestions based on profiles of Sony VGP-BPS8 battery ,Sony VGP-BPS9A/B battery .Chris DeWolfe , Colin Digiaro, and Aber Whitcomb said they will spread MindJolt to more websites and smartphones as well as work with game developers to create tools for online play.

Jones promised game developers that the website will make it easier for their creations to spread “virally” by “very gently and slowly” modifying how friends share news of fun titles for Sony VGP-BPS9/S battery .”I really want to make sure we solve the problems of 13 to 34 year-olds and a big part of that strategy is games,” Jones told developers at GDC. “It will be easier for you to bring games over to MySpace.”

UsbCharger to provide USB communication capabilities

In an advisory, the US-CERT warned that?he installer for the Energizer DUO software places the file UsbCharger.dll in the application¡¯s directory and Arucer.dll in the Windows system32 directory of Sony VGP-BPS9 battery .

When the Energizer UsbCharger software executes, it utilizes the UsbCharger.dll component for providing USB communication capabilities. UsbCharger.dll executes Arucer.dll via the Windows rundll32.exe mechanism, and it also configures Arucer of 14″ apple ibook g4 battery .dll to execute automatically when Windows starts by creating an entry in the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run registry key.

Energizer has issued a statement acknowledging the issue.The company said it has?discontinued sale of this product and has removed the site to download the software of 15″ apple powerbook g4 aluminum battery . In addition, Energizer is directing consumers that downloaded the Windows version of the software to uninstall or otherwise remove the software from your computer.

According to US-CERT, the backdoor component of the Energizer UsbCharger software can be removed by deleting the Arucer.dll file from the Windows system32 directory of 17″ apple powerbook g4 battery . Because the backdoor hosted by rundll32.exe continues to run after the software has been uninstalled, the Windows may need to be restarted before this file can be removed.

This may be achieved with network perimeter devices or host-based software firewalls. The Energizer UsbCharger software does not automatically add an exception to the Windows Firewall for 7777/tcp or the backdoor application of 12″ apple ibook g4 battery . Users of an Energizer USB-powered battery recharger may find themselves infected with malware. The solution? You can use the product perfectly well without the software.

USB-powered nickel-metal hydride battery recharger has been discontinued

According to researchers at US-CERT (United States Computer Emergency Readiness Team), software that accompanies the Energizer DUO USB battery charger contains a Trojan horse that gives hackers total access to a Windows PC for Sony VGP-BPS9 battery .

The Energizer DUO, a USB-powered nickel-metal hydride battery recharger, has been discontinued, said Energizer Holdings, which late Friday confirmed that the software contains malicious code for 12″ apple powerbook g4 battery . The company has not said how the Trojan made its way into the software, however. “Energizer is currently working with both CERT and U.S. government officials to understand how the code was inserted in the software,” Energizer said in a statement.

Energizer’s DUO was sold in the U.S., Latin America, Europe and Asia starting in 2007.Energizer said it has removed the software from its download site of 15″ apple powerbook g4 aluminum battery , and added that although it had offered similar software for Mac OS X, only the Windows version had been infected.The Trojan automatically executes each time the PC is turned on, and remains active, even if the Energizer charger is not connected to the machine.

The Windows software included with the charger is designed to show battery-charging status. When the software is installed, it creates the file “Arucer.dll,” which is actually a Trojan that listens for commands on TCP port 7777. Upon instructions, the Trojan can download and execute files of Sony VGP-BPS13 battery , Sony VGP-BPS8A battery transmit files stolen from the PC, or tweak the Windows registry.

This isn’t the first time that a hardware company has planted malware on unsuspecting customers’ PCs. In 2007, Seagate Technology admitted that an unknown number of its hard drives left an Asian manufacturing plant with Trojan horses of 13″ apple macbook pro battery, , while the year before that Apple warned iPod owners that some of the music players carried a Windows virus.
