One trick: how to properly use and maintenance of the books of the battery. The battery is the key to affect the standby time of laptop. To improve endurance capacity, focusing on battery maintenance is essential.
Carefully read the user manual before using a Asus K72J battery maintenance part;
(2) The first charge, you should continuously charge the battery to 12 hours, and cycle to fully charge and discharge completely 3 times to wake up a new battery;
3 If prolonged use of external power supply, it is best to remove the battery. Many of my friends did not notice this problem, do not remove the battery with an external power supply not only affect the battery life, laptop cooling burden becomes heavier, and shorten the life of notebook computers;
4 regularly charge and discharge. Even without the memory effect of lithium-ion batteries also exist certain inertia effect for a long time not to use lithium-ion loss of activity, need to re-activate. Therefore, if a long time (three weeks or longer) do not use a computer or find the battery charge and discharge time shorter, should be fully discharged before charging the battery, usually at least once a month a full charge and discharge.
5 best to turn off when charging laptop, the battery can be fully charged, do not unplug the power drop in the charge. The charge off the boot charging to shorten the charging time more than 30%, and can extend the battery life. Best in the fully charged for 30 minutes before use.
(6) To prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid battery contacts with metal objects occurrence of a short circuit from happening.
Lithium battery charge and discharge is generally not more than 800 times on one charge, it will shorten the life. We recommend that you use an external power supply, If you use half-way multiple plug power supply, and the laptop built-in battery does not pull out, will make the battery life shortened because every time an external power supply access is equivalent to a Asus K52J Battery charge.
The second trick: Optimizing set the power management options. For laptop users, we recommend using the Windows XP operating system, of course, if the configuration of the laptop is too low can not even meet the minimum requirements in WindowsXP, it is another matter. Reasons in addition to WindowsXP feature-rich, more importantly, of course, because WindowsXP for laptop power management is the most advanced of all computer operating systems, if that can meet the Centrino platform that is certainly better – such as the following shown in Figure 1, 1.4GHz of the Pentium-M when the load is small only operate at frequencies below 600MHz.
If your laptop supports Intel SpeedStep, AMD PowerNow or Transmeta LongRun technology, it must keep in mind the latest drivers installed in order to play its biggest utility, WindowsXP is automatic, Win2000 specific settings as shown below, you can find a balance in accordance with their own requirements on performance and power consumption.
Do not use the screen saver
2 power scheme, select the “Portable / Laptop” and reasonable set the time according to your needs everyone’s situation is different, of course, there is no hard and fast rules, generally Turn off hard disks is set too a little more than a long standby time, so as not to affect the life of the hard disk.
3 Go to “Power Options Properties” Advanced “fair use” power button “, can bring you great convenience, can also enhance the rational use of battery life (see below). Such as: the “the closed portable computer” is set to “standby”, leaving the laptop for a while, not only power but also the confidentiality of the personal information of great help, but do not need to wait for the restart time.
For the use of a line of large laptop (such as IBM, SONY, HP, Toshiba, etc.), usually provide better power management software, and has some special features: IBM power management program can reduce the refresh of the LCD screen rate; TOSHIBA Toshiba’s power management program can be directly in the case of lack of power to turn off any device that you specify; SONY dedicated power management program can set the running speed of the cooling fan, you can also turn off the IEEE1394 interface and do not use MEMORY STICK slot, in order to achieve power saving purpose. Rational use of the technical features of these different manufacturers, also can extend the Asus A32-K52 Battery life of the notebook.
Intel Core i5 processor, equipped with the Chinese version of Windows 8 operating system of the new Surface / Pro debut in China. But many users can not help asking, brand new the Surface before Surface RT tablet PCs difference in the end what? There is a saying, Surface RT is like PC, Tablet PC, the Surface Chinese Edition / Professional is the PC like the Tablet PC. Electronic equipment productivity play the main selling point, taking into account entertainment purposes, from the actual usage scenarios to be considered, it is not difficult to see that the Surface RT and Surface Chinese Edition / Professional is more like a pair of advantages complementary good brother, in their respective fields as the user provide the type of selection.
In terms of “productivity” can be roughly divided into two types: Business and technology-based. A typical representative of the former company managers, business representatives, the main content of the work is read the file, writing documentation, gather information, lectures and demonstrations. Of these users work on computational requirements is not high, the main scenes work mobility is relatively high, vulnerable to unpredictable emergency situations, problems often requires an immediate solution. For them, the most common headaches of mobile office than this:
Long-distance travel, the laptop bulky and inconvenient to carry.
Mobile office equipment to operating system instability, pop in a lecture / demonstration process, error, crashes and other embarrassing phenomenon.
The urgent need to print or copy information found mobile office equipment are not compatible with each other’s memory or printer.
Compared with the Surface Chinese Edition / Professional Surface RT in some aspects of the streamlined functionality, but for the needs of the office, mostly belonging to cut unnecessary places, and enhance a more important performance. Traditional Windows software compatibility, for example, the the Business office users actually rarely used in addition to the outside of the Office desktop software. Write and modify a document with Word, Excel, lectures and presentations with PowerPoint, take notes OneNote, in addition to almost zero demand for the software industry to do the financial statements. Remove traditional software compatible for these users and there is not much loss, the opposite can also be considered as an advantage: all the software after Microsoft Windows application store within a rigorous examination, will never pose a security threat to the user’s computer as the main sources of malware desktop security channel is sealed. This means that all these reasons lead to performance and stability in the traditional Windows is almost fully eliminate: viruses, Trojans, browser plug-ins bundled with rogue software, the registry redundant projects, and so no one left. “Weakened” Surface RT but do not experience traditional PC on the use of the longer the slower the speed, the need for regular anti-virus, from time to time to reinstall the system to ensure the performance of embarrassment. “Stability overrides everything” Business users work does not allow room for error, Surface RT’s reliability is more important than the excess computing power.
Although it is impossible to use ARM architecture processors Surface RT compatible with traditional desktop software, the result is a significant reduction in power consumption. The Surface RT batteries enough to last more than seven hours in the case of continuous use, always solve the problem of the middle of charging the lack of opportunity in a conference room to betake another meeting rooms business family. Of course, from the same strain of the desktop Windows 8 device compatibility with built-in USB interface, ensure that the Surface RT ability to work together with other devices in a variety of emergency situations: from the beginning of the meeting 10 minutes, taken presentation forget to play But it’s hard to see how a bare printer? Track record in the active site, SLR camera’s memory card is full, need to find export photo equipment? Away from the customer’s mobile hard disk copy 10GB giant file? Above all not a problem, because the Windows RT system the Surface RT equipped with the built-in almost all mainstream device driver, no matter what device directly connected to the the Surface RT USB interface on the line.
“Technology-based” user representative career artists, engineers, and programmers. Their place of work is relatively much more stable, most of the time is fixed at one point, and carefully put ideas into visible, tangible actual work. For them, the “mobile office” and inter-provincial and even the relationship between cross-border travel is not the main thing is the large triangle formed from the home, cafe. Power is always within reach, power has never been a problem. What they need is a powerful computing capabilities, and a wide variety of professional software. Visual Studio, Photoshop, InDesign, Auto CAD, above all the tools only be obtained through the traditional desktop mode software, and render images, compile, debug code, and both are the challenges of the CPU and GPU.
Surface Chinese Edition / Professional born precisely in order to meet the productivity needs of technical users. Perfect compatibility to ensure that all tools can come in handy, powerful computing capabilities to better ensure the completion of the task smoothly. In fact, the pursuit of fine operation with a large number of technology users can even external one queen-size touch-screen display, and instantly morph from flat-panel touch-screen all-in-one on the Surface Chinese Edition / Professional. The Surface Chinese Edition / Professional hardware configuration strong addition to the integrated graphics weaker in other areas did not lose to the other brands of one product. On the big screen in full swing creative, Surface stylus fine drawing pictures on the day-to-day work of the technical users is particularly important, even more powerful.
Surface RT and Surface Chinese Edition / Professional by different hardware and software configuration, and offers a variety of options to meet the productivity needs of different types of users, each of them has a unique position, but have a consistent user interface and control experience. Business and technical users should be selected according to their practical needs. The so-called knife difficult to break the triple A, singled Yanyong battering ram, first determine what type of productivity, and then, where appropriate, the selection of appropriate the Surface party is a wise move.

British “Guardian” website published an article titled “In the case of PC sales decline, Microsoft is how to make Windows revenue growth? “Review articles, abstracts are as follows:
The first quarter of 2013, Microsoft Windows division revenue growth, significantly higher than the same period last year to $ 5.7 billion, $ 4.633 billion. Decline in PC sales, Microsoft is how to make Windows revenue growth? Microsoft CEO Steve – Ballmer (Steve Ballmer) invented the “anti-gravity”?
There is no doubt that Microsoft, Windows is still very important. The first quarter, Windows generates 27 percent of its revenue, 45% of the profits. But in the PC business is such a tragic case, Microsoft is how to behave so good?
Last June, Microsoft provides a program based on the program content, users only need to spend $ 15 to buy Windows 7 PC can be updated to Windows8, the program has been executed in December last year, to promote the growth of deferred revenue (Deferred Revenue) $ 1.1 billion. If this data is subtracted from the $ 5.7 billion in revenue in Microsoft’s Windows division, then the remaining $ 4.6 billion the same period last year this figure was $ 4.63 billion.
However, this still does not have any meaning in the context of PC shipments decline. Outgoing Microsoft CFO Peter – Klein (Peter Klein) agreed that traditional PC sales plunged in, when asked Microsoft how to treat shipments decline, he said: “In the PC market, I want to see some third party, such as IDC and Gartner, in the quarter, they believe PC sales decline in the range of 12-14%. ”
Microsoft’s head of investor relations – Chris Xu (Chris Suh) also agree with the view of Klein, when asked about the view, Xu said: “The PC industry is shrinking dramatically, but the Microsoft Windows operating income remained stable, with last year which, OEM revenue performance is consistent with the basic x86 PC market, due to the development of the PC market beyond the traditional PC, to touch and mobile devices, the x86 PC market continues to be challenged. ”
OEM revenue from before shipment Windows on the PC company, if this is in line with the underlying market, the PC will have fallen.
Microsoft Windows business first-quarter revenue last year how to do? Is also due to some other element — non-OEM revenue, such as people purchase an upgrade license, or purchase volume licensing.
- Chris Xu also said: “non-OEM revenue in the first quarter year-on-year growth of 40%, mainly due to Surface tablets and volume licensing business offset by volume licensing business showed double-digit growth. Companies continue to focus on Windows platform, Windows batch authorization is expected to achieve revenues of nearly $ 4 billion this year, nearly three-quarters of venture agreement we signed this year involve Windows. ”
Please note – Chris Xu Surface Tablet views. Surface only sold equipment estimated at 1M-1.5M (In fact, Microsoft did not give specific sales figures for the Surface), revenue (profit) will be assigned to the Windows division. This depends on the price, the sales data; view of the Surface RT price at around $ 900, but mainly through the Microsoft store sales, profit margins may be lower, but revenue growth, perhaps $ 1 billion, perhaps only $ 500 million.
Even so, these data are sufficient to play a significant role. Surface promote Windows revenue growth to $ 500 million, will boost overall revenue.
It is noteworthy that Klein and Xu were not from Windows OEM revenues were flat, they say that Windows revenue. However, even if Microsoft Surface contribution may reach $ 500 million, which also may be overestimated data the Matt Citeworld – Rosoff (Matt Rosoff) Surface contribution value of $ 420 million.
Why? Xu also said: “In addition, this quarter we found that the transition from Windows XP to Windows 7 continues to make progress, and now, two-thirds of the enterprise desktop running is Windows7.
Windows XP’s life cycle has entered the last year, Microsoft is encouraging enterprises to update as soon as possible, which also boosted the revenue of the non-OEM, As XU described above.
What is the conclusion? Despite the revenue growth, but the Windows business in fact, been hurt. Surface and does not contribute to a lot of traditional PC sales in decline, Surface Tablet PC competitors (Klein has clearly said, will soon be a smaller Surface competitors), the only way to really make everyone smiling is update enterprises in XP before the end of the acceleration.
Therefore, an analyst at investment company Stifel Nicolaus & Co’s Brad – ribbeck, (Brad Reback) to the Klein a faint worrying problem: “This time next year, the PC business will decline again it?” Klein replied: “upgrade cycle, especially for businesses in the coming year will be very interesting, I think in the longer term, it is more interesting is that we see the long-term evolution in the equipment market, I think this Compared with the upgrade cycle is a bigger driving force. “remark that Microsoft will shift to the tablet, Microsoft certainly hopes Surface Pro running Windows. He also said: “I think the tablet is the Windows 8 design in the first place, so I think more opportunities from new features, services and experience obtained by the user from the device, rather than just upgrade cycle.”
