X86 Framework Flat Endurance Depth Analysis

December 27, since 2006, chip giant Intel was gradually occupied the processor market absolute dominance. However, the beginning of this century, it has also been AMD's Athlon 64 processor beaten thoroughly discredited. To avoid repeating the mistakes of the past, Intel has begun to take a "step-by-step the camp" secure strategy. Now it is the brilliant achievements, of course, can not be separated from its continuously updated processor architecture, as well as the huge investment in chip manufacturing plant, but really plays a decisive role in it is its internal performance modeling team.

With the rise of the ultra-thin mobile device market, the focus of the industry for the processor performance gradually changed. To create a good user experience, energy consumption began to become as important as absolute performance. Intel also began to realize this point: the internal performance modeling team to guide the product architecture design, absolute performance processor is not the only goal of the user experience, and power efficiency have become the priority factors.

Moreover, in order to reach a better user experience, Intel is trying to transform itself role. In close cooperation, Acer introduced the W510, W700 two flat products and S7 ultra-extreme. Core and Atom processors power control to the lower level for a longer product life, the next generation Haswell processor platform, should be used on the motherboard which non-Intel components, chip giant hardware vendors do detailed provisions. Haswell processor to wait until after the second quarter of 2013 to the listing, the Ivy Bridge architecture strength can not be underestimated. Earlier this year, Intel had announced early next year, you want to Ivy Bridge power consumption to 10W or less. Reason to believe, Ivy Bridge will be the main recent dominant market changes. The moment we see less than Core processor equipped iPad to believe that sooner or later this day.

Earlier, there were horizontal evaluation: Samsung ATIV Smart PC tablet battery is only 30Wh, less than Microsoft's Surface RT flat 31Wh former screen size of 11 inch (1366 × 768 resolution) than the latter ( 10-inch, with a resolution of 1366 × 768), but equipped with the Intel Atom Z2760 processor ATIV Smart PC life better than the Surface RT. Life, ATIV Smart PC in continuous web browser test length of 17% compared to rivals; video playback test, ATIV Smart PC win 3%. Also done by Intel Atom and Tegra 3 processor comparison, in their presentation, regardless of the device as a whole or individual components, using 32nm Clover Trail architecture-power Atom processor is better than the Tegra 3.

The reduction of the power consumption of the end-user benefits are obvious: the running speed of the Intel Atom processor itself must be better than the ARM architecture Cortex A9 core Tegra 3 processor but with a four TSMC 40nm process production Cortex A9 cores. Other hardware configuration of the same case, the Atom processor is not only efficient and energy-saving.

In fact, Intel does not have any special evaluation methods. They just select the device to dismantle and to measure the energy consumption from the level of the individual components, rather than the use of certain software to evaluate the entire system. Typically, the device motherboard contains a number of different components of the display, network, storage, system-on-chip, engineers need different workload conditions repeated attempts to identify the specific CPU or GPU power supply filter circuit.

Under normal circumstances, the power supply for the CPU or GPU filter circuit is a standard LC (inductance capacitance) filter. To capture the LC filter, the series as long as in the inductor before a very small resistance (2-20MΩ), measuring the difference between the voltage across the resistor, and can use the classic Ohm's law to obtain current, and further calculating power. In support of external tools, the the specific kernel power changes for a period of time system-on-chip can also be recorded.

"The power has been turned on not charging" solution to the problem!

When 'the power is turned on has not been charging' this problem, you can do first the following actions:
Pull the plug and re-inserted .. shutdown restart .. it is not shut down every one will open.
If the above operation is done or no role, we more detailed look at the following solution:
The many laptop plugged into the power adapter, and occasionally will be prompted to "the power has been turned on not charged, the Asus A32-F3 Battery can not be charged in this case.Although sometimes restart will be able to solve the problem, but itWhen more reboot still remains the same. " Depressed, battery discharge too much on batteryLife is not good. So, how to solve this problem?
1, check laptop battery powerLook at the battery at this time how much electricity, if the battery is between 90% and 100%, then charge into electricityPerhaps it is normal. Notebook in order to protect the life of the battery, would not be so frequent charge cycles, batteryLess than 90% (a lot of the book is 95%) when it is charging. Some notesInstinct set battery electricWhen it is less than how much charge is a digression.2, check whether the charger is originalSometimes, for example, Dell's 1450 notebook "uncharged" prompt will pop-up boxes, "can not determine the type of the AC power adapter will slow down your system run faster, and the battery will not charge Please connect the AC adapter for Dell 90W or higher power, to get the best system performance. "In this instance, you should first check the charger original charger, to see whether the correct power adapter, if not needed replaced.
3, how to determine the power of the adapterAs mentioned in the previous step, some notebook requires 90W power adapter, the laptop is how to determine the power of the adapter? Generally circular needle adapter notebook charger, the middle of the needle play The power of recognition, did not you imagine the high-tech, right? the needle broken or inside Weld dropped, it would quickly repair go.
4 whether to disable the charging functionSome Asus K52F battery option a "prohibits charging" function, this function below the adapter directly to the laptop power supply without charging the battery, in this case not be recharged into electricity. Is advisable to check the battery option, to see whether to disable the laptop charging function.
Update the BIOS, or be able to solve the charging problemTested, know the battery adapter no problem, then update the BIOS. Updating the BIOS may be able to solve a rare problem. The different notebook BIOS upgrade is not the same, for example, Hewlett-Packard refresh program under Windows, the graphical interface rookie also started to upgrade BIOS smoothly. Some notebook still use plain DOS as the upgrade process.Postscript: laptop charge is not into power is actually a common problem, and sometimes plug in the power adapter, notebook response, this time may be a plug loose, or too much dirt on the plug. General unplug the Asus A32-F82 Battery power adapter and then plug in more than try a few will be able to solve the charging problem

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.

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 Notebook Hard Disk Sound Should be How to Solve

HP laptop repair center, often the customer reaction HP laptop hard drive in the process, sometimes the sound, and thus there is no way to work properly, actually this is not a fault, is a normal phenomenon, so how should we resolve this annoying The sound of it, the main method is as follows:

HP notebook hard drive abnormal sound failure analysis:

Hard work needs stable voltage and current supply, if the voltage is unstable or inadequate power supply current, it will seek a difficult, hard, "Kaka" ringing, or can not find the hard disk or data reading difficulties , may also be manifested as a hard disk suddenly lost in the work process, the data can not be read, etc..

Both cases we use computer switching power supply power shortage or failure to appear above. For the power supply of +5 V and +12 V voltage instability phenomenon, we can use the multimeter test to judge. Too high and too low will not work, generally within 10% fluctuations can be considered to be the normal situation. Current lack for power, we can calculate how much their host's hard drive, CD-ROM drive and related configuration with its full load of power, compared with the Power switch. Under normal circumstances, the power supply power should be greater than the various components of the 10% of the sum of the maximum power, rather than make the two are equal.

Laptop repair engineer experience, there is a situation that is hard to their own problems, may chip failure, may also be damage to the motor, and then the magnetic arm fracture. But here said the hard drive suddenly loud "Kaka" neither insufficient power supply, nor is it due to damage to the hard disk controller chip, but a hard circuit boards and hard disk magnetic arm-powered interface part due to poor contact . The hard drive circuit board powered phase plate body part is not pin or flexible cable, instead of using a crimping method, because the hard disk is used for a long time, coupled with poor working environment, the interface board tinned layer oxidation, disc body spring leaf oxidation, resulting in poor contact between the two, resulting in unstable magnetic arm Seeker motor powered, and seek abnormal, the hard drive does not work.

Troubleshooting:

The solution is very simple, four screws to disassemble the fixed circuit board, remove the board, up to pick up the board, there will be two rows of spring in the interface side of the board, we need to be careful with water sandpaper each a spring piece contacts polished bright. While the corresponding contacts of the circuit board also polished bright, then the circuit board as it back can.

Laptop repair engineers recommended: because of the rise of the price of today's notebook hard drive, if you buy a laptop hard drive to spend a lot of money, if you have encountered more than annoying hard abnormal sound, try the above method.

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!

Little Experience to Share Personal Maintenance Laptop Battery

Laptop battery without charge after the battery is fully utilized

Notebook batteries are lithium batteries, lithium Asus A32-F3 Battery, run out of battery again for a long time is full simply do not have any effect, or even harmful. Because lithium battery does not exist in the so-called "buffer effect", only the early nickel batteries have this feature. Laptop battery life is generally only with man-made damage or natural life. Basically, the battery life is fixed ,300-600 charge and discharge times, and generally available for 2 years.



When the power is connected, the battery can pull or not to pull

Stubbs and do not pull out depending on the actual use: do not disconnect the Asus K52F battery while connected to a DC power supply battery and no harm, because the fully charged battery will no longer accept any power injection, power will all turn directly to the laptop supply system. But when the laptop high-speed operation, the internal overheating is best to remove the battery, otherwise it is harmful.



Proper to charge the laptop battery

Should try to avoid light depleted rechargeable Asus A32-F82 Battery power, because this will give the battery a lot of pressure to cause damage. More feasible approach is to be charged when the remaining 20-30% of electricity. Laptop lithium battery in fact the number of light / charge "is limited, all used to recharge only greatly shorten battery life. The same time, the battery should be charged in a dry place, Also note that the heat problem, which is the enemy of batteries.

Tip: the use of mobile phone batteries, laptop battery is not the same, may be a lot of people will be based on their own experience in the use of the mobile phone battery to determine the feel that the laptop battery should recharge all used this idea is wrong.

 

How to save laptop battery has not been used for a long

The  Asus A32-N61 Battery is fully charged, should put photoelectric save or save? Long-term preservation would put photoelectric batteries will lose their activity, and even lead to the control circuit protection self-locking and can not re-use, fully charged the long-term preservation will bring safety hazards, the ideal method of preservation is to use electricity to about 40% and then stored in the a cool, dry place, about 20 degrees Celsius is the ideal storage temperature. Of course, the best month to take the battery out to use, both to guarantee battery good state of preservation, but not so the loss of damage to the battery runs completely.



Several measures to prolong laptop battery working time

1> lower the screen brightness: fn + down / up key combination to quickly adjust brightness (specific fn + which keys need to look at each notebook, Lenovo general fn + up key, off-screen fn + f2).

2> make good use of standby, sleep and other functions: when a longer period of time without a computer, allowing notebook standby or hibernation, saving power and extend the life of the computer.

3> using the battery, try to turn off the wireless, Bluetooth and infrared port. Removed without the use of peripherals at the same time and avoid enable large 3D programs, games, etc., in order to reduce unnecessary battery consumption.

The Most Appropriate Use of the Laptop Battery

On my books experience point of view, I think about the use and maintenance of the Apple A1281 battery, neither long-term battery shelved sets of books with an external power supply use books with an external power supply, it would be repeated charging laptop battery discharge, and the role of the battery did not play to the extreme, here to share my personal battery use on some of the methods, inappropriate, and also hope the wing of a master ~ ~ ~ · ·

My AppleA1322 battery is generally no sets in the books, probably about a month apart time I installed the battery is not connected to an external power supply, so simple to use battery, the time is probably more than two hours, set the battery alarm 5%, see the power prompt, connected to the external power supply to continue to use the to observe battery charging, the battery is fully charged at least pulling power after shutdown, unplug the battery, the next time you turn on the use of previously just then external power · · · This cycle laptop battery is about a month once fully charged, which helps protect the battery, you can extend the battery life, after all, the laptop battery is not how cheap it ~ ~ ·

But in general, the Apple A1039 Battery can be so considered, often power outages in some places, books, or connected to the battery is used in conjunction with an external power supply better, although it would be more wear and tear battery, but doing so will help to protect the books comparable battery you must be well aware of; secure power supply in some big cities like, can be considered to protect the battery, the price of books, after all, uninterruptible power, the books on the power or will not be any harm.

Emergency Treatment Act Laptop Battery Aging

 Just using a laptop computer running time, suddenly found that the battery does not just bought that had never been seen to maintain a long time, you have not thought about, at this time, your Toshiba PA3692U-1BRS Battery is aging, and then how to do it?

 Laptop battery aging is a normal phenomenon, in theory, replace the original battery is the best solution old computer radiate vitality. But, as you say, the original battery prices are high, so if you do not want to buy expensive original battery had with prawns describes "computer" "discharge Dafa, adventure shorting the positive and negative. Originally nervous, expect sparks result silently. An amount to find multimeter, voltage is zero. Then the multimeter current block discharge from high to low gear, the result is not current. First of all, the purchase of related models compatible battery, this method is mainly applied to some of the big brands of notebook products, and compared to the original battery, compatibleToshiba Satellite A300-1ME battery prices are generally cheaper half there more, in addition to the power than the original battery inadequate basically use or not, but I suggest you buy some brand compatible battery manufacturers; replacement batteries, not compatible battery supply the compare Pianmen notebook brand or model on the market, this case can only find some computer repair station to old batteries to replace the Toshiba PA3728U-1BAS battery to solve the problem, but this method requires more knowledgeable users of technology, otherwise easily by unscrupulous repair business to deceive you best find a knowledgeable friend to come forward on behalf of processing, so that there would be safeguards.

       Laptop battery failed hardware, "books" so the "books" is probably also true, and it is used by people to pay attention to the care and maintenance. Buy large manufacturers brand battery is on the one hand, and the rational use and maintenance of one hand.

The Dell Laptop Battery maintenance need to pay attention to what?

Notebook battery maintenance way. What use is a laptop battery maintenance of the taboo? The notebook maintenance pull out if a power outage how to do? Dell MT264 battery maintenance of good words can use up to how long? See below. Laptop battery a long time, it is often sufficient dissatisfaction, or even show damage, it is necessary to pay attention when in use some maintenance tips: regardless of your notebook uses lithium laptop battery or nickel-metal hydride batteries, as far as possible to the battery charge basic then charge as possible (less than 5% of the electricity), this is the best way to avoid the memory effect. In fact, the lithium-ion batteries also have a certain memory effect, much smaller than the nickel-metal hydride batteries just nothing. However, the need to pay attention to charge, try to avoid too long, the general control within 12 hours.

Dell Vostro 1500 Battery battery longevity than by the total use of time, but by the charge and discharge times to decide. Here is the importance of maintenance of the notebook. If you always installed the battery into the notebook and not taken down, even if you turn off the machine and remove the AC power, the battery would not like to imagine as has remained fully charged state. Notebook batteries due to the integrated control circuit in the battery, so that even when the power shut down your computer also power consumption. As one connected to AC power, the battery will start charging, whenever power on or off, your laptop battery will be repeated charge and discharge affect battery life.

To do this, use the AC external power supply is best to unplug the battery or notebook battery in a fever state for a long period of time to impact their life. Maintenance battery unused for long periods, charge and discharge at least two months time, in order to guarantee its activity. In the custody of the battery, there is a need to pay attention to the problem. Currently, most laptops use lithium-ion Dell Vostro 3350 Battery for long periods of time used, often prone to the phenomenon of excessive discharge, may no longer notebook battery charge. In order to prevent excessive discharge in the semi-state-of-charge to save it in a cool, dry place, and then once every six months, then power charge to half the state.

In addition, factors affect the battery life of the books, including the use of environmental temperature (recommended for use below 30 ℃), battery storage temperature suffered shock size battery. Notebook battery will be in use for a period of time after the aging (how maintenance is the same), the specific expression of the resistance, when both ends of the charging voltage rises faster, so easy to charge control circuit is judged to have been filled with capacity natural decline. Notebook battery calibration is an effective way to deal with aging batteries, a few laptop will have a dedicated battery calibration software. If your laptop does not have a dedicated discharge software, then the battery can follow the steps for maintenance:

● screen saver is disabled;

● In the Windows Power Management power scheme will be set to "always open";

● Alert tab will "low battery alarm" is set to 10%, the operation is set to "no operation";

● "a serious power shortage alert," set to 3%, operating as "waiting";

● the screen brightness set to maximum;

● Make sure all windows are closed, and to save the data of all previous work;

● Make sure the battery is charging more than 80% after unplug the power and all external devices.

Discharge end of the notebook will automatically shut down after the power plug for laptop charging, this process can be repeated 2 to 3 times, the purpose is to let the Dell Latitude D420 Battery current discharge, which discharge state in our daily use is impossible to achieve , the effect of those dedicated discharge software.
