Why Dell Studio 1555 Laptop Battery Exploding
In general, the current battery of Dell Studio 1555 have good comprehensive protection. Not only are multiple series / parallel battery circuit board itself also contains two modules: protection module PCB Board Module and smart battery indicator, a set of design includes battery protection IC protection (to prevent battery in the prime nivelsobre the discharge, short circuit), the second-level protection IC (to avoid a second surge), fuses, LED display, temperature control and other components.
In the mechanism of multiple layers of protection, including the charger, computer in an anomalous situation, the battery can only be converted to automatic protection status, if the situation is not serious, often working after re-plug, no explosion. The first is the most severe, a short circuit will directly and very hot, resulting in vaporization of some of the electrolytes, slice battery cover.
According to analysis, Dell 1555 battery explosion caused by a short circuit or overload, probably manufactured lithium batteries, because the manufacturing process is deficient, leaving the existence of product safety problems can occur at any time, as the two poles should be insulated but metal powder or sheet copper and aluminum foil membrane drilling burr among them, resulting in micro short circuit.
There is also a very special situation, the charger or equipment due to special reasons, lithium battery instantly provides the high voltage / strong currents that leads to severe stress, such as charging voltage v mbm1260 suddenly rises to 12.9 v is greater, then it would produce a high flow, should be cut in the circuit charge current to recharge the battery, but action due to battery voltage lithium, depending on the design of current protection is very weak This can lead to damage of IC, battery protection.
Studio 1555 battery to lose the protective function and extremely damaged, after crystallization overload around lithium metal needle piercing points ahead of several micro chip short circuit, causing the battery temperature gradually raised, until finally battery explosion, fire phenomenon, which is now a lot of main reasons for the “mess” of portable batteries.

Some Knowledge That You Don’t Know About Laptop Battery
A battery has two essential characteristics, the voltage in volts (V) and the amount of electricity expressed in Ampere-hours (Ah) or milliamp hours (mAh). The battery power is calculated as follows: Voltage (V) x amount of electricity (Ah) = Energy (Wh). For example: 19.5 V x 4400mAh = 85.8 Wh. Thus we speak of capacity for energy instead of power as general.
What type of batteries used in laptops?
At present, all the batteries that come with laptops are made using Li-Ion technology. These are a type of lithium in the lithium ion remains in the state. These batteries are expensive and that lithium is an expensive material. Its main advantage is the amount of energy we can store in a small volume.
Key Benefits
* No memory effect or very low
* Excellent amount of energy / volume due to the physical properties of lithium.
* Auto-download (natural discharge when the battery is not used) minimum.
* Much safer in relation to the first lithium batteries (in the metallic state) thanks to an integrated electronic circuit.
The main drawbacks
* Price, because of the complexity of manufacture and the material used (lithium)
* Significant deterioration when the battery is discharged below 10% (can lose up to 20% capacity at once!).
* Current limited load because of their internal technology and the danger of lithium, so the burden may seem slow.
* Low temperature resistance: It is recommended to use at a temperature between 20 and 25 ° C, and should not exceed 40 ° C if they can not hurt. Never be achieved at elevated temperatures in the range of 75-80 ° C because they may explode.
* As all these batteries deteriorate over time and nothing can reverse this process.
But you should pay attention to. The overall battery (batteries, lead acid batteries or lithium batteries, etc..) Pollute the environment so it should never be thrown away. They should be recycled (in some countries will find in supermarkets and computer stores where you can leave them for recycling). Never attempt to open a battery to repair it because you can burn or severely intoxicated.

Myths Rechargeable Batteries For Laptop And Mobile
It is often said that the first time we use a device equipped with a lithium battery (as I say, they are often called Li-ion) should be allowed to charge for eight or ten hours, but two or three hours (typical load one of these batteries) this device tell us that the battery is fully charged. This really was recommended when using Ni-MH batteries, but with the Li-ion is not absolutely necessary: a lithium battery always carries an overload protection circuit which is responsible for turning off the power once detects that the cells that make the battery has reached its standard level (usually from 4.2 volts).
Therefore, once the device says “full charge” does not enter more current to the battery and has no effect whatsoever on the leave her more time with the charger connected. Also they say that should do complete cycles of loading and unloading to avoid the “memory effect”, that Ni-MH batteries was that if we put in charge a completely discharged was not missed part of the capacity of the battery from overcharging some of its cells.
In Li-ion batteries this is not necessary, and even more frequently as recommended and load cells are less time with current flowing through them. Li-ion batteries have no memory effect either and therefore we can load them better we come without having to wait until they are completely sold out as it did with the old batteries.
There are a number of things that are the worst thing that can make a lithium battery:
· The Heat: Li-ion battery loses capacity if stored in hot areas. Best suits them cold, but with keeping them below 25 degrees Celsius is more than acceptable. This is why batteries degrade some laptops very quickly if the design has not been taken into account that the area of the battery should be cold, ie, away from the hard drive and microprocessor.
· Store fully charged for a long time: it is best to keep a battery at half load, if we do so with the battery fully charged your battery cells suffer and will deteriorate over time. It should be stored fully discharged for a long time what we will see in the next point.
· Leave the battery to discharge completely, if a Li-ion battery becomes completely lost its charge will not load. This point is reached when the device is off because the battery has a very low level of energy, since that is responsible for the above-mentioned circuit protection. Over time the battery is losing charge itself (self-discharge rate) and if we can load many months to lower the minimum threshold needed to start charging and the battery unusable.
To extend the battery life:
* Reduce heat: The Li-Ion are highly susceptible to high temperatures, so use your devices in a cool environment will extend its functionality.
* Turn off wireless transmissions: Infrared (IrDA), Bluetooth and Wi-Fi are real vampires electricity, being equivalent to maintaining a cell at any given time. Turn off these features when necessary.
* Avoid using your CD or DVD: The spending not only borne by the laser, but also the motor that spins the disc. Better not to mention the writers?
* Reduce the brightness of the screen: Some teams do it automatically, generate less light, less energy demand.
* Remove memory cards or USB keys: Do not let its small size fool you, energize it requires an additional flow of electricity. This is especially true for small devices such as phones or PDAs.
* Avoid using audio applications: Even with headphones, the sound generation requires a constant expenditure of energy. Worse still if they feed external speakers.

LG Kompressor: The Vacuum That Follows You!
A new line of vacuum cleaners from LG is launched with great particularity that is we will, LG Electronics announced last week at the IFA 2011 technology fair held in Berlin to launch a product in its line of vacuum cleaners. This Sony vgp-bps2c has the Follow me, this system gives the team can follow the steps of the user during the cleanup effort avoiding the cable or pull the weight of the machinery.
LG Kompressor line with smart sensors location has three sensors on the body and another on his fist that give the user the ability to avoid those jerks always end cables at break or break the cable or the same tube suction. According to user movement of the vacuum cleaner body moves automatically. Thinkpad t400 battery once again creates a new niche market and changes the way customers conduct their daily tasks, “said Young-ha Lee, president and CEO of LG Electronics Home Appliance.
Besides the new sensors for LG vacuum cleaners still have a compact device that dirt from a dust cloud forms when we empty the dust collector. According to the manufacturer the product has not yet scheduled for all markets in the world but promised that in less than 6 months and will be in all markets in which Acer aspire 9503ewsmi battery is present. “We launched a product of our revolutionary line that brings higher performance, lower power and a great convenience for the user.
Meanwhile Samsung presented its new robot vacuum cleaner called Navibot S, the company has just introduced its new generation of intelligent vacuum cleaners. The S Navibot vacummed Robot Cleaner is the ideal device for those who do not have time or are not very loving household cleaning tasks. Navibot In this edition of the same is 10% smaller than its predecessor and received good implements, besides its being sufficient provided just a Sony NP-BG1.
The little robot has more autonomy given specifications of the product. The mode of dust collection is a clear example and work fairly practical and intelligent. By detecting the magazine is also full of notices are placed outside the collection cup to continue working without problems. Also when the Compaq presario c500 battery is placed outside the glass collector equipment are cleaned automatically brooms vacuum.
Good News and features were kept in this release as the video camera now able to record the temperature with a resolution of 30fps and the maps where she worked as future routes and optimizes the system Visionary Mapping Plus. Another useful tool is the volume sensor dust, which could increase the suction power of the Acer aspire one battery in places where there is more dirt. For now Samsung has not indicated what the price of this exciting new vacuum cleaner.

Energy saving of your laptop
For longer be able to use your laptop without a power outlet nearby, you can use power management (power management) work.You can change the BIOS settings thereof. For example you can slow down your CPU to work (economically) if you do not taxed. Whether your hard drive if you disable Dell xps m1710 battery for X number of minutes have not used.Usually there are already pre-configured settings such as (Maximum safe, maximum performance, etc. ..)
Do not start randomly changing settings, but think first moment about the possible consequences.The most energy at a laptop screen, CPU, CD-ROM drive and hard drive. (Usually in that order.)Working to increase the HP pavilion dv5000 battery can be one or more of the following things:
* Adjust the brightness of the screen as low as possible. You just save not only energy, but the life of the “lamp” will extend.
* Turn off your screen when you’re away. Or get a short delay the screen saver. (Use a “useful” screen. Flying Windows logo are not useful: You save nothing, instead you consume extra processing power.)
* Lower the volume or use headphones.
* Make sure the air vents (in and out) is not anything to be blocked, so that the processor is kept cool. Heavy processors and memory have their contribution to the heat, so the less things you do together, the less heat, less cooling required, and the longer your HP pavilion dv5 battery lasts.
* Remove CDs from the CD-ROM drive if you are not using. Some laptops have the CD constantly spinning and a lot of energy.
* Remove PC cards (PCMCIA, Cardbus) if you are not using them. Make sure to buy these cards if they are in an energy saving mode can be put.
* Use the sleep mode or hibernation (Suspend To Disk) mode, or turn off the computer when you’re just not used.
Turn on the external connectors (serial, parallel, infrared, USB, …) in the BIOS if you are not using them.Never work without batterySome clever people who read all this and to protect their HP pavilion dv4 battery will perhaps be inclined to their laptop without the battery (but with power) to work. This also is not recommended.The tension on the wall is full of peaks and valleys. These “wrinkles” are effectively eliminated from the battery, which actually serves as a capacitor.
Without battery, these lines passed to the laptop-electronics that can usually not take place and sooner or later gives up the ghost. (And a battery is still cheaper than a new laptop …)Old batteries are defective liver is best reflected in the manufacturer. These can then be recycled. (And sometimes you get discount when buying a new battery.) If you manufacturer the HP pavilion dv7 battery still will not take, write a letter of complaint and deposit it in small or hazardous waste at a battery collection point nearby.

Dell Inspiron 14z Review
Dell recently unveiled its new model Inspiron 14z during IFA 2011 event, this is a device designed to be a very portable notebook plus all the power possible. The company Dell is undoubtedly now one of the three most prestigious in the world, their computers not only attractive design but we have Dell ww116 of the highest quality as well as powerful hardware as well as high quality, and without 14z doubt that the model is a clear example of this.
This is the successor to the Inspiron 15z model and has a slim design resembling that of an inch MacBook Pro to be less than the product of the former company of Steve Jobs. Maybe an inch in other products may not be much but if we are dealing with a Fujitsu fpcbp200 that must be lightweight and portable no doubt that inch makes a big difference in the market. Or in this case is perfectly to the view that while we gain we lose power for their portability and vice versa.
The Inspiron 14z has a screen with a display type, high-definition widescreen resolution of 1366 x 768 pixels. This feature is the same that is present in the model Inspiron 15z but 14z Inspiron options are a bit limited when Fujitsu fpcbp59 comes to processors. Here you can choose between an Intel Core i3 or i5 while the Dell Inspiron 15z is possible to choose between an Intel Core i7 i5.
For its part the operating system and comes pre-installed is Windows 7, but the most interesting of this notebook is that we will be able to customize it to our needs. For example at maximum capacity we have an 8 GB RAM and a HDD of 750 GB, thus having a wide range for our work are powerful or simply to display Fujitsu fpcbp80. With this customization we can have a perfect device to work well in a video editing as a simple Web browsing and reading emails.
This model also features an HDMI port and has the HD trailer SRS Premium Sound, this is a high quality audio for movies or listen to our songs. Besides all this we will be able to convey the image of our computer screens without requiring cables over all by the use Intel Wireless Display. The Dell Inspiron 14z also has a hp 500 battery and memory card port and WiFi multimedia, USB 3.0 and Bluetooth.
For his part in terms of aesthetics Dell also has not neglected its quality and gives us the choice between two colors, so we have the Black Diamond or Red. The notebook will start this month and be sold in stores such as Best Buy in the UK. Dell wants to start a major expansion in the field of technology with hp 520 battery that are more palatable to the user providing both great mobility and versatility, so in recent years Dell has hired several new designs well known in the segment.

Introduction To New Nokia 100 and 101
The Finnish company no doubt a few years ago was the undisputed leader in the mobile phone segment in all different ranges, so we had an insurmountable Nokia N95 and simpler models among these simpler models had the legendary Nokia 1100. This model is perhaps the simplest mobile phone in the history of Sony vgp-bps9 s but in turn the model that has achieved sales amount and in turn has several interesting figures such as the mobile phone.
It has lasted throughout the time and more people have used throughout his life. According to the Finnish manufacturer Nokia 1100 is the most mobile phone text messages sent throughout history and is also the mobile phone that many people used as a secondary phone. Now the company is seeking to achieve the same but with a Sony vgp-bps9 adapted to 2011. This similarity and starts from its name and the company launched the Nokia 100 and Nokia 101.
In the first quarter Nokia realized that there is a large public purchasing dual SIM devices and because it launched its two newest models, the X1-01 and C6-00. The mobile phone manufacturers ‘real’ recently that there previously had to fall into the Chinese replicas to have this feature. So thanks to the great success of the latter Toshiba pa3534u 1brs battery the company decided to launch two new models with this feature and it also achieve very similar to the one Nokia 1100.
Both phones are targeted for emerging markets, both have the same design, same 1.8-inch TFT, torch, pre-loaded games and FM radio. But in the case of the Nokia 101 this is the only one of two dual SIM and have a little more sophisticated, including for example a more powerful pair of speakers, mp3 player attached and support for Lenovo 40y6797 up to 16 GB. According to its directors in emerging markets such as 85% of the population have mobile phones instead of smartphones simple.
Everything reminds us of the Nokia 1100 from its small screen, even in this case is to color, games and also had that model and turn the flashlight that these models were typical at that time. The devices also will be released this semester in Europe and the MSRP will be no more than twenty dollars for the Nokia 100 and 25 euros for the Fujitsu fpcbp64. Although Nokia has always wanted to have other models focus on “strong” or workgroup and the company knows that the mobile phones of this type are very important.
Nokia wants to again be the leader in this segment and surely these two teams is going to achieve and by the company say their phones have an advantage over their competitors and have a colorful screen, rugged construction and a battery life. The Fujitsu fpcbp155 is sold in the colors Black and Coral Red Phantom turn the Nokia 100 offers five colors, we have the Red Coral, Legion Blue, Pink Festival, Ocean Blue and Phantom Black.

Samsung Replenish: Green Mobile
Every day new devices with the simple goal of being environmentally correct, perhaps because of all the great benefits that this indicates a company. For example in many countries have an organic product provides discounts on the company tax which undoubtedly is the search for many companies. This is the case of the Dell rn873 battery company Sprint along with Samsung have a 100% organic device.
This is the Samsung Replenish, this is a smartphone that comes with the Google Android OS 2.2 but apparently it will be updated to version 2.3 of Android. Besides this it has a rear panel solar is optional and costs about 29 dollars. This is the first smartphone on the planet ecologically correct that runs Android and thus Dell vostro 1710 battery can have access to 150,000 applications available on Android Market store.
Replenish the Samsung has a little basic specifications as a QVGA display, 2 megapixel camera, 256 MB of RAM, WiFi, GPS, Bluetooth and 2GB memory card with support for cards up to 32GB. No doubt that Samsung is the leader in the development of mobile “green” and looking for new technologies for the development of Apple a1175 battery using recycled materials or pass through creative processes that do not harm the environment restore ambiente.
The product is manufactured from recycled plastics and packaging is also done on these products so the phone becomes the ideal for those who like to care for the environment. Another interesting detail is that the Samsung Replenish comes with a wrapper that you can use to send your old phone for Apple macbook pro 15 inch battery, be a great strategy to increase sales of your device. Meanwhile Sprint will reduce its monthly plan rate $ 10 for users who purchase this device.
The device has a QWERTY keyboard and is available in colors black, blue and pink from June in the United States. Sprint CEO Dan Hesse said they plan to provide the maximum possible both equipment cost and ecological advantages of production, that is why they have made a Apple a1061 battery reduction in the monthly rate. With another operator also launched a new model Samsung Samsung Restore in partnership with Virgin.
The structure has 80% recycled material and uses 50% less plastic composition. The gadget has a QWERTY keyboard and a conventional slide-type, 2-megapixel digital camera, microSD Card slot and a 1.9-inch display that achieves the resolution of 240 x 320 pixels. The Apple a1012 battery has applications that connect users directly to social networks like Twitter, Facebook, MySpace, Gmail, Hotmail, Google Apps and many other features can keep the user connected to internet.
These investments show how much green technology is no longer just a mere fad or trend but which is already a reality for many businesses and consumers. Many see this niche is a great chance to improve not only the environment but the business conditions in a large ecosystem. Restore The Samsung does not have release date or official price for its sale.

Bento: Notebook, Tablet And Smartphone
An interesting concept but a little farther from reality is called Bento, this is a concept that integrates a computer notebook, tablet and smartphone.
With the arrival of the new tablet market, which was inaugurated with the launch of the first of the iPhone this created a niche of sales between the space between the notebook and smartphones. The designer responsible for the project is called Bento Rene Lee and I think this concept in red uses each of the different forms of a Dell inspiron 1564 battery to increase the connectivity of all devices and also the lifetime of the devices.
This project was a competition created by the Fujitsu company, called A Life With Future Computing, is present a dock that includes a monitor 15 inch OLED display, integrated with a rectangular 11-inch tablet that serves as an extension of the monitor or keyboard and turn a smartphone with 4 inch size on your Dell inspiron 1570 battery at once which can be a “touchpad”. In terms of design is undoubtedly attractive for its small thickness and very light weight.
In addition to this we have a lithium battery that is recharged with solar power and hard disk type 1 TB SSD, these two components are removable. The idea no doubt is great when we think we can have a Dell inspiron 1764 battery working together, because not only have everything in one place but all three screens can work together to perform functions that require more than one.
As we see from the pictures could have such a score on the monitor, the piano keyboard on the tablet and a sound controller on the smartphone. By this all men divide their processor and RAM. Being a concept really is a bit hard to believe that soon we will see this Dell xps m1530 battery, but we lose nothing to dream and thanks to its design and its high functionality would be a bestseller.
Not only does your screen flexible solid or small notebook, the designer also remove the trackpad device to save space. But to have these functions, the creator inserted a notebook mouse in the notebook, just enough to push a button so that it arises from within the Dell vostro 1500 battery. Feno in turn is half the size of such a MacBook Air, but in turn has the same screen size of a MacBook Pro 17-inch all thanks to its flexible OLED display.
In addition to this keyboard which has a great similarity with the Apple hardware keyboards was also reduced, so that people rest their hands on a flat surface such as Van Hoof said, providing that the user can more simply typing in their Dell vostro 1400 battery. Feno is another very interesting concept and perhaps a little closer to reality than the previous one, this is a foldable notebook designed by designer Niels Van Hoof, by having a flexible screen size is more compact, easier to carry.
