Into the largest computer maker Apple iPad sales only on the ultra-HP PC
According to foreign media reports, both the computer unit sales, or computer sales, Apple has surpassed all Hewlett-Packard, the world’s largest computer maker, this situation is mainly due to strong sales growth and iPad record highs recorded. Apple’s Tablet PC sales not lost on the low-cost market similar products, Apple also said it will “continue to remain in the field of tablet PCs bold innovation.battery for inspiron 1545
”
According to the just-released first-quarter results, Apple iPad first-quarter sales reached 15.4 million units, Mac computer sales reached 5.2 million units, so that its first-quarter sales on the computer more than 20 million units . According to Gartner’s report, the fourth quarter of last year, HP’s worldwide PC shipments to 14.7 million units,Pavilion N5140 battery
while sales of Lenovo and Dell for the same period were 12.9 million units and 11.6 million units.
iPad tablet blocking the impact of low prices
Apple iPad tablet PC market, low price is not subject to the threat of similar products, the other way on the other PC makers have a tremendous threat.
When asked by the Amazon Kindle Fire iPad price tablet PCs and other low impact of this issue, Apple CEO Tim Cook said he was very satisfied with iPad sales,TOSHIBA SATELLITE 1955
and sales agents that the iPad more than the number of wholesale quantity, this also led to Apple’s tight inventories, and this argument also breaks after the Kindle Fire iPad Tablet PC sales will erode the rumors.
Cook said that Apple, iPad Apple will provide long-term opportunities, and also reiterated Apple’s management that “one day sales in excess of the entire tablet PC sales.” Cook said: “In fact, the United States The market is very interesting, IDC’s latest data on desktop computers clearly shows that the previous quarter, the Tablet PC has sold more than a desktop computer. It can be seen, all indications have shown that the Tablet PC market will usher in huge growth momentum. ”
Cook’s views on the Kindle and iPad
Cook said that in terms of competitiveness,Thinkpad T42Series Battery
iPad eco-system has its own advantages, for example, has a large number of applications, and other Tablet PC platform, the number of applications has a lot less. Cook said: “I think the Tablet PC user wants to carry through a large number of functions, they will not want to have limited functionality of the Tablet PC product or electronic reader. Other Tablet PC sales may be considerable, but I or that it would like to hope to get iPad users do not like the product is limited to those functions. ”
Cook also said: “We will continue to innovate and tablet computer products, we believe that we can continue to work with all current opponents are also introduced to compete with tablet PCs, or those in the future may enter competitors in this industry.”
iPad sales, but without prejudice to the Mac over PC sales
Market demand for the iPad prevents the growth of PC sales. In the same quarter, Microsoft’s Windows revenue has dropped by 6 percent, but sales of Apple’s iPad, and the company itself does not have a negative impact on Mac sales.hp adapter n193

intel SNB platform Jingxian chip gate
1 May, the United States on Monday, Intel Corporation officially announced in early January this year, just with Sandy Bridge Series “second-generation Core architecture processors’ launch of the 6 series chipset (codenamed Cougar Point) found a design problem. Although Intel has designed the chip level that has been amended, but the revised version of the chipset in the new pre-market, Intel has decided to suspend all around the world 6 series chipset shipments.
SNB latest intel chipset platform
The chipset in question covers all Couger Point products, including P67, H67, and other sections of the mobile, commercial model. Intel’s official description of the problem exists in the SATA controller modules, “In some cases, SATA interface degradation may occur over time status, affect the hard disk, DVD drive SATA devices such as the performance.”
In the ensuing conference call on a special, Intel further explained that this problem exists in the circuit design 6 series chipset provides four SATA 3Gbps interface, specifically the interface circuit in a PLL clock tree transistors. The very low voltage transistor can only switch, but for its Intel imposed in the design of high voltage, resulting in high leakage current. Over time, increasing the leakage current may eventually lead to complete failure interfaces.dell laptop battery inspiron 1545
From the user perspective, the problem is with the use of performance time, the board four SATA 3Gbps interface bit error probability may appear higher and higher, until the device is completely unable to connect.
It is noteworthy that the first 6 series chipset SATA 6Gbps interface, adding the two do not have this problem. Therefore, if the notebook design, using only two SATA 6Gbps interface (SATA 0 / 1), then the problem will not be affected. DIY user in order to avoid problems, you can also try to SATA devices connected to the two SATA 6Gbps interface, or a third party to provide the SATA interface on the chip.
Intel said in a shipment of more than 100,000 6-series chipsets, the company began to receive a chip set SATA interface for fault reporting. Until early last week,Toshiba PA2487UR battery
Intel has finally succeeded in the laboratory to reproduce the problem, and then after several days of research has identified the problem, come up with a solution. In the final on Sunday evening, Intel decided to suspend all 6 series chipset shipments, and publicly announce this event.
Since the problem is the chip circuit design level, can not drive, the software correction, Intel chips will be manufactured in the photomask stage, replacing the metal mask layer to be addressed.Inspiron 1545 dell battery In fact, due to problems inherited the old transistor design are non-essential circuits, Intel needs to do is to completely disable it in the circuit in a transistor only. And the problem is the circuit design in the latter part of the updated Intel in step B was introduced last year to provide testing of the product but there is no problem.
Updated design and re-create the new 6 series chipset will begin shipping the end of February, April, returned to normal production output. Future new products such as Z68 chipset release schedule will not be affected by this incident, is still expected to release in the second quarter of this year.
6 series have been sold for the chipset, Intel and OEM partners that will receive the returned product, and plans to pay all the affected chipsets, amendment or replacement costs. The user does not need too much tension, their hands of the 6 series chipset can be assured that the system is still normal, patiently waiting for manufacturers of replacement and maintenance program came out. Because although the problem has been confirmed,but in fact the user under normal use conditions, three years, there SATA interface failure rate of only about 5%.
As the machine, replace the motherboard product to be recalled, is expected to Sandy Bridge platform, PC, laptop or 6 series chipset will be out of stock at least until the end of March, the company originally expected to launch in February, a large number of Sandy Bridge platform for new products almost certainly will delay publication.
Reason: The chip giant indeed affect the whole body, and good public relations are handled properly the Intel crisis, swift and strong response to this tragedy as comedy becomes the ability to hope that everyone can learn.HP N193 Charger

According to technology blog AppleInsider reports, with the strong sales of iPad, Apple for the first time in the computer sales and revenue than HP. While the outside world that the iPad’s market may be low-cost tablet erosion, Apple is optimistic that they will continue in the Tablet PC and it takes another “crazy innovation.”
Apple sold 15.4 million last quarter and 5.2 million units units iPad Mac, total sales of personal computer HP Probook 4431S battery equipment more than 20 million units (compared to 37 million smartphone sales still a gap). Research firm Gartner reports that HP’s worldwide PC shipments for the last quarter of 14.7 million units, while sales at Lenovo and Dell were 12.9 million units and 11.6 million units.
The outside world had predicted that Apple sold 13 million units last quarter, iPad, this data structure than the study last fall Canalys estimates even higher. Canalys has Apple is expected to surpass this year will become the largest computer maker Hewlett-Packard – Apple ahead to achieve the target.
Apple in the Christmas quarter sales and profit than the same period to more than double Microsoft’s.
iPad is not affected by low-cost tablet threat; it will threaten PC sales
When asked about low-cost tablet PC, especially if the Amazon Kindle Fire iPad will impact on, the Apple CEO Tim Cook (Tim Cook) said that his sales for the iPad “very happy” HP 4431S battery at the same time, retail sales than the distribution of the much larger, making the company’s worldwide channel has plenty of inventory, which will erode iPad market with the Fire’s argument is contradictory.
Cook also said, iPad is “a great opportunity for Apple,” the company’s management believes that “business will be more than one day tablet PC business.”
He added: “In fact, IDC recent data show that sales of tablet PCs last quarter over the desktop PC. It has been seen from different places in the event of significant changes in the market.”
Cook said: “In terms of competitiveness,Dell Inspiron 1501 battery
iPad ecosystem is self-contained.” iPad has 170,000 models specially designed application, and contrast and other Tablet PC applications only a few hundred. “I think people want a lot of things Tablet PC applications. (Compared to content-based low-cost tablet PC), we think that the functional advantage of the Tablet PC.”
Cook added: “Other Tablet PC will of course take some of the market, but I do not think those who really want an iPad user only has limited functionality hope we will be crazy in this area of innovation, we have the strength and those who are or about to enter the tablet market competitors. ”
iPad erosion of the PC market,Dell XPS M2010 Adapter but no hurt Mac sales
iPad is the gradual erosion of all kinds of PC market – Microsoft Windows-on-quarter revenue fell by 6%. However, sales of Apple iPad has no negative impact on their Mac.
In contrast, iPad, iPhone and iPod sales seem to have the halo effect (halo effect), to attract more users to the Apple notebook and desktop computer market. Apple said its subsidiary sales of notebook computers and tablet PCs strong Mac sales are the prices per week.
More than 1 / 5 of the Mac through Apple’s retail stores sold – a figure of about 1.1 million units, while about half of the consumers for the first time to buy Mac.
Haier notebook somatosensory experience with camera recognition application
The evaluation of the contents of the third generation of Qi Ge Haier notebook pre-installed Air Magic somatosensory applications. Air Magic is a designed specifically for home use somatosensory applications, via a laptop camera to identify the user’s 
body movements to achieve control, it includes Haier Toshiba PA3534U-1BAS battery
designed for children six baby program application and somatosensory interaction games for families Instruction entertainment use. Next we look at its specific performance.
Haier notebook has the third-generation 7 Columbia flame red, coral, blue, gray three-color body technology, the continuation of the first generation of brushed aluminum-magnesium alloy casing, the official definition of it as the machine’s “King Kong cover” non-slip wear good .
Camera next to the pickup holes was rather special, porous type of design is not common in other machines, which is three generations of the highlights of Costa Rica 7, Haier HD noise reduction features voice recording draw on from here.
The first thing we see is Air Magic’s main interface, where we Dell Inspiron 6400 battery
can see pictures, music, baby plans, video and game five modules, the lower left window to identify the camera operator to 2-3 meters from the camera place to operate, so Air Magic can be good to identify your head and two hands, and just below the bottom right of action prompted by word and action tips to teach you how to somatosensory operation.
We chose to enter the image module, where we can reach back through the left hand above his head to the purpose of the home page, right page requires natural swing left to right, the left hand page is left with the natural swing, pictures of each module Dell Inspiron 1564 battery
six pages to show the form of graphs.
Video and music forms module is similar to the user through the body movements for the choice of music and video and then play,
the player’s position in the middle of the screen.
The next is to introduce Haier Air Magic somatosensory application of the most important of the two modules: baby plans, and games. First talk about the baby plan, the picture looks very suitable for pre-school children to use Q, the scene contains a variety of barriers, like basic arithmetic, common sense knowledge, etc. for pre-school children to learn the content, and these are the games present form, very suitable for family entertainment in the Instruction to use,
so boring learning process more fun.
There are six modules in the game to set the somatosensory interactive games, the farm wars, jumping music, cross country, moving action look, hide and seek and fat war UFO,Dell Inspiron 1750 battery
these games have to be to use body movements to the game, not only can be achieved entertainment purposes, but also to achieve the purpose of physical exercise.
We cross-country for everyone to look at the game description, select the game, the system will first pop up game tutorial to teach you how to play the game,
so it would be very easy to get started, then we will use the power of the body to the game, and left to hide, right flash, jump, whether it is for a child or adult, can be part of it. In particular, note that before the game in progress, looking for a relatively spacious place to put notebook, do not cause unnecessary injuries, safety first.
Haier Air Magic somatosensory general application of this innovative design is very commendable, experience a sense of human-computer interaction is very good, you can let the children have fun Dell Inspiron 5000 battery
while learning the knowledge,
to achieve a true win-win, interactive games, adult children can participate in them, entertainment, exercise can also achieve the purpose. It’s enough to say that also exist, such as unstable as the positioning choice, really want to go directly to hand click on the screen to choose, but for newly developed software, these things are slowly improving, I believe the application of Haier Air Magic somatosensory there will be a very good development.
Thin, high capacity, long life, these are the outstanding characteristics of lithium batteries. For this reason, lithium-ion battery, it has rapidly replaced the nickel-metal hydride, nickel cadmium batteries role as notebook computers and other portable devices for optimal battery life. Recent times, continuously exposed laptop battery explosion, the laptop battery time and time again into the cusp, the user can do this lingering fear, the source of lithium Aspire 5315 Battery in the end is the driving force or a time bomb?
Study to find the mystery of the battery fire
In general, the current notebook lithium batteries themselves have a more comprehensive protection. It not only from the series / parallel composition of multiple batteries, the circuit board itself also contains two modules: the protection circuit board (Protection PCB) module and Smart Battery Gauge Board module, its design includes a set of battery protection first-level protection IC (to prevent battery over charge, over discharge, short circuit), the second-level protection IC (to prevent a second over-voltage), fuses, LED indication, temperature control and other components.
In the multi-level protection mechanism, even in the power charger, laptop unusual circumstances, the VGP-BPS9 battery can only be converted to automatic protection status, if the situation is not serious, often still work after re-plug, not explode. Laptop battery explosion face serious facts, the reporter sought the advice of professionals and power of a well-known manufacturers of design engineers.
According to analysis, nothing less than the lithium VGP-BPS13A/B battery explosion caused by a short circuit or overcharge, most likely when one is in the manufacture of lithium batteries, because the manufacturing process itself is flawed, leaving the existence of product safety problems that may occur at any time, such as should be insulation between the two poles of metal dust or copper foil and aluminum foil membrane perforation burr, resulting in micro short circuit. The former situation is most serious, it will directly cause a short circuit, and a lot of heat, resulting in vaporization of some of the electrolyte, the battery cover stretch.
In addition, there is a special case, the power charger or laptop due to special reasons, the lithium SONY np-fs12 battery to provide instant high voltage / high current caused by severe over-charge, such as the charging voltage by a sudden rise to 12.9V 12.6V or even higher, then there will be a high charging current generated within the circuit should move off the battery charge current, but because of some lithium battery charging over voltage, over current protection design is weak, which may cause damage to the battery protection IC, so that the laptop battery to protect the function of the damage, charging over the needle after the pole piece on the crystallization of lithium metal, piercing point resulted in a number of micro short-circuit, causing the PA3535U-1BAS battery temperature is gradually increased, until eventually the battery explosion, fire is occurring, This is a lot of laptop battery “hot” the main reason.
Add a layer of umbrella cover
At present, protection from the battery point of view, the battery pack before charging part of the traditional chip makers are played most of the programs provided precise control of charging voltage and charging current role in the over-voltage and over-current control does not provide the appropriate solution. Thus, the protection of the canon battery pack is completely dependent on the battery itself, such as over charge protection, over discharge protection, over-charging current protection, over discharge current protection, thermal protection and so on.
Protection in place need to prevent the first-level protection IC MOSFET failure or short circuit caused by over-voltage fault, so the second-level protection IC is generally considered to be the protection of the battery group last line of defense. In this regard, Bump E (O2 Micro) product manager for Hong Shizhen expressed different views, he believes that the protection for the VGP-BPS2 battery pack can move forward, additional control functions through the charger to achieve detection and control of battery charging action , which will undoubtedly further enhance the level of protection to the protection of lithium batteries with security.
To this end, the O2 Micro power management for portable devices developed by Cool Charge solution which combines the one called Cool Battery Technology battery protection technology, its greatest feature is a traditional chargers generally do not have the OVP (over Voltage Protection) and OCP (Over Current Protection) function of the two NIKON en-el9 battery protection, the technology has been embedded in them Cool Charge IC chip.
By Cool Charge IC chip, the power charger will largely assume responsibility to protect the battery. Under the control of the Cool Charge IC chargers, compared with the traditional design (see Figure 1), the need to significantly reduce external components, eliminating the need for Q3 and Q4 part of the design and reduce the failure rate. Q1 preserved and in Q2 (to improve the original design elements) between, Cool Charge IC set up a detection point, through the factory settings, the detection point of voltage and current settings are set slightly less than the Latitude D600 Battery manufacturers safety requirements. Thus, in charging voltage or current exceeds the Cool Charge IC to set the value of the security after the voltage or current, IC to control the Q2 off, first cut off before the battery charge protection; from detection frequencies, the detection time for battery protection ms interval level, and through the chip to detect, can be very easy to implement millionth of a second level, you can use a high frequency of continuous detection, the first step to achieve the purpose of protecting the battery pack.
Media reports say U.S. troops captured bin laden recorded future planned attack notebook
U.S. officials said on Wednesday, by us troops killed in the al qaeda leader osama bin laden in Pakistan in the house, found his living a notebook, notes include the name global “terrorist tycoon” planning future attack plan.
According to Canon BP-2L12 Camcorder battery the report, an unnamed U.S. officials says to the reporter, in be captured bin laden inside the residence items, including a believed to belong to osama bin laden notebook, osama bin laden in the booklet recorded his future attacks launched the ideas and plans. These plans may just osama bin laden some of the ideas, no forming, also just short description.
Report says, and the notebook is not a diary, not recorded osama bin laden private things, no record he had engaged in activities or previous whereabouts.
Report says, because the U.S. military has in the blitz of seized computers, hard drive, DVD blanks, flash drive, and video devices, osama bin laden notebook is not taken seriously.
The national security advisor Tom. Abidan the Aaron (Tom Donilon) had evaluation said, the United States through the captured bin laden items about him to a large number of information, equivalent to that of a “small library”.
