Outgoing Microsoft CFO Peter Crain (Pter,, Klein) in the Microsoft conference call with analysts today hinted that the company may be about to launch 7-inch tablet.
Crain said that Microsoft will be launched in the coming months "new compact touch-screen device. These statements can be seen, he seems to admit that Microsoft's upcoming 7-inch Windows Tablet PC.
Windows 8 released last October, only supports 10-inch or larger screen size. But recent news about Microsoft's next-generation operating system Windows Blue is rampant, there are rumors that this system will support the 7-inch tablet.
Microsoft also modify the rules of the manufacturer, allows Windows touch-screen device with a resolution of 1024 × 768 screen, which is the same as Apple's 7.85-inch iPad mini.
Crain conference call, said he expects that soon there will be more cheaper Windows Tablet PC market. Intel CEO Paul Otellini (Paul Otellini), said on Thursday, the price of 300-400 U.S. dollars Windows Tablet PC will be listed this fall, other Intel-based Tablet PC (Android system may be equipped with) the price will be as low as $ 200.
Microsoft promises that Windows developers at the annual meeting in June this year released more information on the Windows Blue's. The market is expected, this system was first expected to be launched this summer.

Grasp the two Main Laptop Batteries
Now more and more people use the notebook, also will appear as notes of
experts, one of the main components of this lithium battery good
notebook lithium batteries? Laptop lithium hp Pavilion dv9000 Series Battery? Grasp two things:
1. To appropriate current charge and discharge.
2. Minimize discharge insufficient charging or excessive discharge.
Although the battery is a consumable, lithium ion batteries are no exception. But everyone wants to own battery fine spirit of God, to age and do not rattle're finished, no one wants to own battery on the half-dead not to pull a living, has been to the edge of the two or three years, good people taste tasteless is how is it that you say is not it?
Well, get down below began to talk about batteries. To explain, confined to the lithium-ion battery.
An appropriate current charge and discharge
General literature and national standard lithium-ion battery, said the lithium-ion hp 484170-001 battery charging current should be between 0.2C to 1C. This is with the charging current of the battery capacity, such as your battery is the 4AH then is 0.2X4 = 0.8A 0.2C charging current means that the charging current should be between 0.8 to 4A. Generally, the charging current is as small as possible in the permitted range, the lithium-ion battery charging beginning of constant current charging, in my IBM R31, this current is 2.8A, equivalent to 0.7C is charging circuit control, can not set. Although no such charging indicators exceed the standard requirements, but is actually relatively large, especially when the capacity of the battery used for some time after the fall of the charging current may be more than 1C. The laptop charging users care about the length of time has become indicators, manufacturers were forced to charging current is set at such a high level.
So the first step is to reduce the charge current. I have a friend working in the lab, and a variety of equipment ranging test him. First string on the power outlet on a resistor try, the results of the current is reduced, but became intermittent charging, this is not a good thing. After trial and error, 4 ohms is an ideal value, and this time the charge current is about 0.8A, very stable. This is just the current flowing through the machine power connector on the battery charging current is estimated to be larger, it should be slightly larger than 0.2C. Specific to a different machine, this value may be different. In addition, as the hp HSTNN-LB11 Battery voltage increases, the charging current is decreased, but the decrease amount is small, less than 0.05A. In this state-of-charge, the charging circuit does not seem to be working, the battery indicator is not lit. Such as battery voltage rises to 12.6V, the charging circuit kicks in, battery trickle charge state at this time whether the series resistance is irrelevant, the charging current is controlled by the charging circuit, charging circuit automatically end after the last full charge. Throughout the charging time is about 5.5 hours, if not resistance, the charging time is about 3.5 hours.
The lithium-ion hp Pavilion DV7 series Battery is very delicate, and good charge control circuitry is required. This charging method, can reduce the charging current to extend battery life, while use of the books of the original charging circuit controls the charge, it is relatively simple to implement, just buy a power plug (that is, from the power supply into the books the kind, it is best to buy two, the latter also with a good quality) and a resistor can, pay attention to the resistance tall, after all, about 2W power consumption , otherwise the resistance will be more heat, it is best to do a constant resistance wire, almost independent of the resistance and the temperature of the resistance wire. However, the disadvantage of this approach is obvious, is not in charge, while working with books. Another charge when there will be a strange phenomenon, I omitted to write, you try to know Fortunately, this phenomenon disappeared into the trickle charge state. Charging time is not a big problem, start charging anyway, before going to sleep at night and wake up the next day and charged, of course, if you are a night owl or sleep special short time, that is another matter.
Small current charging problem solved, and now discharge problem. In fact, this is difficult, after all, the book is used to work, the discharge current with different working status different methods mentioned here is limited specifically to restore the operation of the battery capacity.
Start the machine, the power management set never to sleep (standby) and hibernation state (hibernate), and others are set to the most power-saving modes, including CPU speed, turn off the hard disk, turn off the monitor, the other in TP management program close some do not have the hardware, such as a sound card, and then open the hp ProBook 4510s Battery status display window and let it run in the foreground! ! ! Close other programs, in particular, is a screen saver and other timed run program! ! Do not use the machine, do not close the lid, and let the battery completely discharged (discharge minimum value should not be set to 0, I set 3%). Display and hard drive shut down after the discharge current is about 0.5A, which is able to achieve on my IBM R31 minimum discharge current, discharge the battery to the machine will automatically turn off after a set minimum value. Entire discharge lasted about more than four hours, depending on the battery capacity may vary, also used this time to pass sleep.
Finally, to emphasize that the above method is not dead, especially discharge ten times there time to do so can, or else even battery Why? Charging the best are charged with a small current course, if much-needed battery directly to the power plug is inserted in the notebook can be.
My battery using this approach are now charging and discharging of 14 times, the capacity has been maintained at more than 45, while the battery design capacity is 43.2 during decline, but this charge and discharge time after all restored.
At the beginning about two points, one is the appropriate charge and discharge, the second is not to discharge less than the charge, the following look at how to solve the discharge insufficient to charge:
1. To appropriate current charge and discharge.
2. Minimize discharge insufficient charging or excessive discharge.

Why Remove the Laptop Security?
Introduction: With Labor Day approaching, a new round of travel peak is beginning. When everyone in the airport security, there has not been asked to remove the security measures alone laptop it? Why can not be used together with the computer bag through the X-ray screening it?
Laptop Why separate checks?
We enjoy the convenience notebook, have to bear the inconvenience of security when the notebook. Laptops complex internal structure, easier to refit, and most of them are metal objects. Its image by the irradiation of the X-ray machine is more complicated. If there are other metal objects on the computer bag, the security staff is hard to read, easy to miss some of the dangerous goods check potential danger, and some computer bag metal accessories can also interfere with the security staff checks.
Carrying a laptop through security need to pay attention to what?
1, in order to improve the security check speed, laptop security is best to remove the computer bag, and other parcels separately through the X-ray machine check.
Into the CD-ROM in the computer's CD-ROM drive, do not, do not external U disk, wireless network cards and other hardware devices. Power supply, mouse, it's best to separate from the computer into the X-ray machine in check, so as not to cause unnecessary trouble in the security.
3, not to use the laptop bag to carry lighter. Airports have smoking at large to ensure the needs of smokers, and checked and carry lighters are prohibited.
4, in order to speed up the efficiency of the security, try to paste, paste items checked, do not put the computer package.
Domestic flights for travelers to carry the number of units of the computer is no hard and fast rules, but the computer battery there are certain requirements, carry two laptops, it is best to separate the battery with the computer and the battery pack with bubble paper and other insulating materials.
Many recent laptop bag manufacturers are trying to improve the design of computer packages to minimize the security of the passengers brought trouble.
China Eastern Airlines maintenance the Teahouse Tips:
When the security of the passengers do not bother with the security staff For everyone's safety, please! I believe that with the development of science and technology in the future, the screening process will be more rapid.

Evaluation ASUS UX31A Touch touch screen experience outstanding but the price is too high
January
4 news, Windows 8 changes not only the performance of the introduction
of the operating system the Windows UI touch interface, the same also is
to give manufacturers a huge imagination play space. Currently, there
is included in the sale of Windows 8 devices, notebook, deformation this
tablet PC hybrid notebook and other forms equipment, these devices are
beginning from the era of the traditional mouse and keyboard, a gradual
transition to the touch era. The Asus Zenbook Prime over most of this
product line is an obvious example.2011, Zenbook Prime series get together and market. In last summer Zenbook Prime walk the line of sight of consumers UX31A and just past the end of 2012, Zenbook Prime UX51VZ grand debut. Recently, ASUS has once again released a UX31A upgrade version UX31A Touch ultra-extreme, officially carry Windows 8 and touch elements to reload debut.
UX31A Touch people first think UX31A this ultra-extreme, and try to touch elements combine. But actually UX31A Touch to change not just blend the touch experience, performance has also been greatly improved.
Designs
Imitation metal material Zenbook products mentioned numerous times, UX31A Touch also uses this material base and craft sophisticated textured back cover. Although frequently use the same kind of material people may feel fatigued and visual numbness, but from the point of view of the manufacturer, ASUS found a way to highlight their own style aesthetic philosophy, adhere to this style to convey to the user is also worthy of recognition.
Zenbook series, UX31A Touch also retains the workmanship and solid body imitation metal sites put pressure on the case and will not appear deformed. Even so, slightly light weight will affect the feel of the product. UX31A Touch a joyful place is equipped with a touch screen and no compression on the generation of narrow border design.
The UX31A Touch machine weighs about 1.3 kilograms, and not the adaptation touch screen UX31A weight relative body size is also consistent: 12.8 x 8.8 x 0.11-0.71 inches. The edge of the left side of the fuselage has a USB 3.0,3.5 mm audio interface and SD card slot. Right side, respectively, for the power supply, USB3.0, video output, as well as micro-HDMI interface.
Accessories look, Asus has caught up with the trend of peripherals. And UX51Vz, UX31A Touch with a mini VGA to VGA adapter, also equipped with an Ethernet adapter adapter.
Keyboard and touchpad
And imitation metal base, UX31A Touch backlit keyboard also retains the the Zenbook products consistent style. Fuselage built a comfortable island-style keyboard, a basic no difficult to get started for ordinary users. In addition, control of key processes and key spacing just right, both to ensure the efficiency of input and experience, but also to reduce the probability of misuse.
Vary from the Zenbook series as a whole product point of view, the experience of its touchpad, but most of the touchpad user experience remarkable, the touchpad UX31A Touch can simulate the same out of the slide on the screen to scroll , two-finger zoom and other basic gestures. However, during use, also appear similar touchpad sticky user inadvertently pressing operation, and thus in most cases far higher than the frequency secondary click.
Display and speaker performance
UX31A Touch display, with a 1920x1080p high resolution IPS display is clear, satisfactory. Even in the brightness set to 70% of the cases, the screen is still bright and accurate color reproduction performance. In addition, the viewing angle of the screen is also very prominent, smooth screen can lead to reflection effects will make people confused, especially when in full-screen playback video.
The fuselage is equipped with 13.3-inch touch screen called UX31A Touch the super pole hallmark of this. Touch screen gesture touch operation sensitivity superior to authentic restore Windows 8 features. Back to look at the e Zenbook UX51Vz, taking into account this device has excellent mouse and keyboard control experience, and therefore is not equipped with a touch screen nor will it impact user manipulation, but Windows 8 user touch auxiliary input experience the effect is very amazing. Many users use Windows 8 touch in this ultra-extreme, often unnatural in some of the old section of the device touch screen, which is a new operating system dynamic magnetic characteristic charm another system.
Not exactly a lot of functional development, in the process of using the Windows 8 operating system, often there will be a large error sound. Play music, but very small volume. Even if the volume is turned up to the only law-abiding describe UX31A Touch speaker effect. Although the user can select the external speakers, but this will shorten the life of the equipment.

HP EliteBook 2170p Evaluation Rugged Life
Recently, slim Win 8 mixing equipment and the super has attracted a lot
of media attention, but many business users only want a powerful,
lightweight, ultra-portable device. The 11.6-inch hp 484170-001 battery
EliteBook 2170p is a such a device, it offers strong performance and
reliable life, durable, and weighs only 3.2 pounds (1.45 kg). The price
of $ 1,099 (equivalent to about 6850 yuan), the EliteBook 2170p's
competitors, including the Lenovo ThinkPad X230 and the Dell XPS 12.
Well, EliteBook 2170p is not your best choice?
Design
EliteBook 2170p has a sturdy magnesium alloy case looks shatterproof beaten look. HP said it after the durability test of 115,000 hours, including thermal test and drop test. Reach military standards, but 2170p than the average consumer notebook durable much.
Like other recent Elitebook, this notebook is simply decorated with the HP logo, to executives like soft appearance. Open the top cover, you may feel the shaft a little stiff. Matt matte black plastic frame inlaid with a 11.6-inch display with a camera on top of it.
The magnesium alloy keyboard base is made of silver tone with top cover, 3.7 x 1.5-inch touch panel under have a dedicated button. The EliteBook series keyboard left and right sides about half an inch each space, fingerprint reader just below the arrow keys.
EliteBook 2170p power button on the right side of the fuselage is a slider. At the bottom has a docking station port, made of matte black plastic.
EliteBook measurements of 11.5 × 7.6 × 1.0 inches (29.2 × 19.3 × 2.5 cm), weighs 3.2 pounds, it is shorter, thinner and lighter than the Lenovo ThinkPad X230 (3.4 pounds) and Dell XPS 12 (3.4 pounds).
Life time
Our hp Pavilion DV7 series Battery test (the display brightness set to 40% continued to use Wi-Fi Internet), the device 48 wHr battery adhere to 6 hours and 44 minutes, 25 minutes more than the class average of 6:19. than XPS 12 5 hours 46 minutes, much longer, only more than the X230 6 hours 56 minutes 12 minutes shorter.
Unfortunately, HP does not offer a larger capacity hp HSTNN-DB75 battery. In contrast, Lenovo provides X230 a 9-cell battery, can persist in 12 hours and 17 minutes, also provides battery plate, can extend the battery life to 20 hours and 46 minutes.

HP DV4 Laptop Battery Charge and Discharge
Minimize
discharge insufficient charging or excessive discharge in fact, a good
solution to excessive discharge, not the end of discharge limits set too
low can be, I have been a 3%.
Often with a Hewlett-Packard hp Pavilion dv4 Series Battery may just not a long time, such as notebook battery left 70%, Hewlett-Packard (HP) DV4 laptop battery is automatically charged if the switch to the power supply, then such a cycle, there is no Hewlett-Packard (HP) DV4 laptop battery life is not the number of cycles absolute dead, but always it will reduce the notebook battery capacity lithium-ion laptop battery is said to have no memory effect, but in fact only relatively low memory effect, nothing more. Unfortunately, IBM did not provide a solution to discharge less than the charge method, however provide a foundation to solve this problem. This is what I found on the R31, may not necessarily suitable for other machines, but the method should also be far off, after you've tried do not forget to share posted.
R31 charging circuit based on the status of the power to decide whether to charge the hp Pavilion dv4 Series Battery. Power supply output voltage is 16V, error of plus or minus 0.2V, if the voltage is lower than 15.5V, the charging circuit not give notebook battery charge, while books can work properly, this is the foundation of IBM offers a solution to the problem. But the foundation is really vulnerable, because if the voltage is lower than 15.2V, the books will be converted to power laptop battery, even if the power plug in the books is useless. In other words, we can toss the space is 0.3V.
If you can find a 15.5V, more current 3A switching power supply, then the problem is solved, otherwise please continue to read.
Reduce the output voltage of the power supply 0.5V is not an easy thing, the series resistance is not enough, because the voltage across the resistor will change as the current size. I use a silicon rectifier diodes required to allow current 2A above, otherwise the tube too hot. Silicon rectifier diode forward voltage drop to between 0.7 and 0.5V, just to meet the requirements. Now this type of pipe are plenty in the electronics market, the price is less than 2. Specific to the different book on the situation may be different, the best time to install hand a digital multimeter Cece. Forward tube is connected in series in the power output of the power plug and then followed by a buy notebook. The diode reverse does not matter, the book does not work it wants to, and then, in turn, can be connected to the.
Thus, the decline in the power supply output voltage of about 0.5V drop too much, the book will be converted to a laptop battery work, if the drop is too small, the book will give notebook battery charge, the specific number you tried to know in their own book.
Of course, if your Hewlett-Packard hp Pavilion DV7 series Battery is already full, this circuit is not necessary, and you can not use it directly to the power outlet connected to the books.
So far, mentioned at the beginning of the two problems are solved. Now you test the results, the estimated results in a different book may be best to first take a circuit to try, so it took 10 money wasted Finally, I wish you good luck! Good use of your lithium laptop batteries!
Special note:
Most likely to commit errors when modify the plug is polarity engage anti-(the diode polarity to engage in anti-does not matter), so you must be carefully examined, measured with a multimeter and use different colors of the wires connected to the positive and negative. I do not know that the power the polarity to engage in anti-burn the books will have not tried!
Often with a Hewlett-Packard hp Pavilion dv4 Series Battery may just not a long time, such as notebook battery left 70%, Hewlett-Packard (HP) DV4 laptop battery is automatically charged if the switch to the power supply, then such a cycle, there is no Hewlett-Packard (HP) DV4 laptop battery life is not the number of cycles absolute dead, but always it will reduce the notebook battery capacity lithium-ion laptop battery is said to have no memory effect, but in fact only relatively low memory effect, nothing more. Unfortunately, IBM did not provide a solution to discharge less than the charge method, however provide a foundation to solve this problem.

Consumers Recognized "Disease" - Battery Endurance tTme is Short
Has become consumers recognized the "common problem" for the laptop, the hp ProBook 6540b Battery life is short. Cause
laptop short life time in battery mode, then in the purchase and use of
early, we should all advance from what has been understood and carried
out to circumvent it?As
we all know, even if you're just a little to increase the brightness of
the laptop screen, plus a memory or plug in a mouse expansion card what
will shorten the life of the laptop battery mode, it is very realistic
to say: laptop battery life
time will always become the people's frustration, because at least no
qualitative change in a short period of time, then we really can not do
anything? could only watch was only three to five hours of battery life
time is reduced to a two hours? answer of course is no.First
of all, unless it is necessary, otherwise we try or not in hp HSTNN-OB42 Battery mode
using a laptop, the best in the mains environment, especially for
prolonged use of laptops, not the expectation The laptop battery bring you much convenient, even if you book the battery life eighty-nine hours.Second,
if so, under battery mode, it is best not to use too many laptop
peripherals or functions, for example, if the use of the environment or
conditions allow, the best display brightness to the lowest, unplug the
mouse use
the touchpad, turn off the built-in network card or sound system, in
short, to do to maximize the life time, you must have the "sacrifice",
this time using a laptop computer is a bit painful.The
last is that the recommendations of the cliché, to your laptop ready
twelve spare battery, this is the most sensible and effective solution
for people who often use battery life.Existing
laptop battery technology product background, to get longer battery
life time is still a dream, especially when the premise of the
lithium-ion battery technology products still dominate, but there is no
quality of life to enhance the laptop The wide range of battery life time "breaking ten (hours) of the road is still far away.
Laptop battery repair method(A) The battery causes of damagehp EliteBook 8540w Battery use for a long time, it is often sufficient dissatisfaction power, even display the battery has been damaged, the specific expression of the resistance larger increase in the voltage across the charging faster. So easy to charge control circuit is judged to have been full capacity will naturally decline. Relatively large battery internal resistance, discharge voltage drop, high speed, so the system is easily mistaken for the voltage is not enough, the lack of electricity. Found the battery operating time is comparatively short, appropriate measures should be taken.(B) The battery refresh program to restore the battery discharge timeBrand laptop has a battery refresh program, we can use it to repair the battery. Example: a laptop with the battery for the nickel-metal hydride (Ni-Mh) batteries, due to the usual improper charging and discharging lead to battery discharge time is getting short, only less than 5 minutes, if carrying a laptop to work, it is very inconvenient, what can restore the battery discharge time?The response to these circumstances, we can use the notebook official website launched battery refresh program to refresh the hp Pavilion DV7 series Battery, put it back in the discharge time, specific methods are as follows.(1) the use of AC power for laptops, the first official website to download to a laptop refresh program.(2) Restart the computer, press F8 to enter the boot menu and select safe DOS mode.(3) to enter the directory where the file you just downloaded, perform a battery refresh program, read the warning message, asked to insert a floppy disk, and then press Enter to execute the self-extracting operation.(4) with this floppy disk to boot the computer screen prompted.(5) Follow the prompts to unplug the AC power, the program will automatically Ni-Mh battery discharge, discharge is completed, the system will automatically shut down.(6) due to the high temperature of the battery should not immediately start, let the battery cool for a while, plug in the AC power supply.(7) to boot the computer with a floppy disk, this file will automatically run the refresh program, and asks the user whether to proceed.(8) In this case, the refresh program began battery refresh process back to the DOS prompt A:> when the refresh is complete.(9) Turn off the computer and charge the hp 484170-001 battery until the light turns green.(10) The above process is repeated three times to get the best results.In addition, many lithium battery failure is the failure resulted in battery packs in a power-saving core, this phenomenon can not be avoided. Because each cell batteries can not be completely consistent in nature with weakened for a long time after some quality begin to age, while the destruction of the whole (series after) the discharge curve. Interested readers can try to open the battery pack, and the help of the multimeter, you can quickly find the damaged batteries (abnormal voltage). If conditions permit, the replacement under the corresponding parameters of batteries can be qualified product.

Third-party software correction charge discontent laptop battery power
Notebook battery charge dissatisfaction electric solution
If the books do not have built-in battery correction tools, atcal software to calibrate the new model of software to calibrate the battery. BenQ s42 notebook, the author of, for example, use two years later, the battery life is only about 50%, then connect the ac adapter, the battery charge to not charge so far.
1, the run batcal tool, click on the "set slow discharge" button (Figure 1), choose a slow discharge mode.
Slow discharge mode is selected
2, click "begin calibration" button, then "Power Options" window pops up, then recommended to select the "Portable / Laptop" mode, and all projects under the program are set to "never"
All items are set to "never"
3, the screen saver is also closed, and click the "OK" button, then you are prompted to discharge, after discharge, will pop up a prompt window that prompts you to unplug the ac adapter when the battery is completely exhausted. The system will automatically shut down, and then plug in the ac adapter is normal to recharge. If you want a quick discharge, you should select the "fast discharge" mode, screen brightness to maximum, and can not operate the notebook in the discharge process.
