How to choose the notebook

Below is a brief description about the samsung x05 laptop keyboard choose and buy notebook aspects of common sense, for everybody reference when the choose and buy.
Understanding of the home computer basic composition and performance.

Home computers that is home microcomputer, also called home computer. The computer is actually a system, and the concrete by the hardware and software of two main components. Hardware is usually refers to computer material equipment, including host, a keyboard, a monitor, hard disk and printer, etc. Software is refers to the procedures and relevant documents, it subsystem software, application software and program design language of three parts. Computer hardware and software relationship as recorder and the relationship between the tape. Software is the soul of the computer, if there is no software, computer samsung x06 laptop keyboard have no practical significance, and conversely software more rich, computer function and the greater the effect. The hardware and software, is 1 and practical computer. And decided to 1 computer main performance of the curriculum, and the host computer is the central processor chip referred to as CPU. The most popular home computer is C series.

This series is the first by the IBM research, they adopted the Intel company's 86 series chip as CPU, therefore, all the computer class to differentiate all and PCU performance Numbers consistent. At present, this kind of machine from low-grade to high-grade according to the arrangement of ordinal for 8086, 80286, 80386, 80486, 80586,, etc., the greater the number, the higher the grade of the machine, the corresponding price expensive. Master the choose and buy of home computer method. 1 normal computer samsung x10 laptop keyboard less to say several thousand yuan, for the average families is a lot of expenses. When the choose and buy should master some basic methods:

1, want to choose the mainstream models. Because the computer belong to high-tech products, the renewal speed is very quick, and almost every year to launch a new class, so must choose popular advanced type, and try not to buy out the product.

2, want to choose high cost performance model, buy one computer can not simple to pursue cheap. Of course, economic conditions are relatively good family can also buy the streamlined.

3, pay attention to the computer samsung x15 laptop keyboard inner quality. At present the computer market multifarious, many brand, the product purchase channel complex, single from the appearance is difficult to discern their advantages and disadvantages, therefore, when the choose and buy as far as possible buy PinPaiJi, namely buy some domestic and foreign famous brand product, the product quality and after-sales are guaranteed, but the price will be a few more expensive. If choose compatibles, but must please adept when staff, it is difficult to guarantee the quality. Want a choose and buy 1 already practical and satisfactory home computer, usually to understand some basic computer knowledge and market. Our country computer market the source is ample, the brand is numerous, both foreign PinPaiJi, such as apples, HP, Siemens, Fujitsu, such as the product of the company, also have the domestic credibility good are domestic famous brands, such as lenovo, JinChangCheng, illumination, and wave, founder, etc. Series of home computer, and various domestic and international brand of compatibles for users to choose.

Personality with notebook computers have gradually into the public life, as a technical integration high products, in the purchase process, there will be a how to choose how the problem of choice. Now everybody to buy laptop computers samsung x20 laptop keyboard are focus on the basic frequency and configuration. Actually besides these performance index, notebook other details more worthy of our attention.

The first is visual experience. Actually no matter notebook computer basic frequency or or configuration or belong to notebook computer is internal accessories, they mainly is the notebook computer performance, only a suitable concept, the user should choose a satisfying a need configuration, and we usually man-machine conversation most LCD display screen is a factor that cannot be ignored. Before the user or stay in image color display effect pursue, now it has promoted the height of display quality. Through the survey of consumers, we can see that the notebook computer samsung x25 laptop keyboard users to LCD display quality attention is their rare common demand, direct result shows that quality decline is screen window, users to liquid crystal screen window very hate and cannot tolerate have accounted for 87.41% of the total sample. Visual effect is good or bad has become many user evaluation notebook computer quality important index. Notebook window problem has become more consumer to notebook for one of the outstanding problems. Pin-points of window light will influence the use of user experience, which leads to the user's visual disturbance, the heavy users may be misleading to graphics misjudgment, even to the customer cause irreparable economic losses.

Second is the application of feeling. For a new computer for samsung x30 laptop keyboard, it is a kind of work tool, can effectively improve the user work efficiency. Improve work efficiency, performance of the product in the interoperability, in nowadays represents the technology is a wireless network. A wireless network, you can not affected by wire, network line or additional adapter card the fetter, can even directly from cable online transferred to the wireless network environment, and don't have to worry about job will interrupt.

CPU radiator main points of choose and buy

Fin is an important part of air cooling toshiba satellite a10-203 laptop fan radiator, no heat radiator, heat conduction cannot be achieved, it is impossible to will CPU heat away a lot. Influence fin characteristic factors have material, contact area, bottom thickness, convection heat exchange area and fin of fins and air flow direction of consistency.

1. Fin material
In metal materials, silver of the toshiba qosmio x300 series laptop cpu cooling fan thermal conductivity of the highest, but the cost is high, Pure copper second, but processing is not easy. Air cooling of radiator fin generally USES 6063 t5 aluminum alloy, this is because of the aluminum alloy good workability (pure aluminium due to insufficient hardness, it is difficult to cutting processing), surface treatment easily, low cost. But as the cooling demand increase, comprehensive use of various high coefficient of thermal conductivity of the material is the trend of The Times. Some fin adopted pure copper or copper aluminum combination way to manufacture. For example, some radiator bottom using pure copper, it is to play copper coefficient of thermal conductivity, the heat transfer quantity relatively large advantages, and fins of the section is aluminum alloy sheet, is in order to easy processing, will heat exchange area as far as possible, so that convection heat transfer increases. But this method is the most difficult point lies in how to copper and aluminum type fins fully connection, if the connection is not good, it will influence the effect of heat dispelling.
 
2. Contact area
According to the theory of heat transfer and the quantity of heat conduction is proportional to the contact area. For CPU air cooled radiator is concerned, CPU toshiba qosmio x305 series laptop cpu cooling fan surface area has more and more small, contact area has been limited, and radiator bottom and CPU surface can't completely smooth, so need to choose the proper heat conduction medium fill the void, in order to increase the contact area, achieve the quantity of heat of the heat source of the purpose of take away. Fin suction quantity of heat to try to pass to fins to convection heat exchange, this mainly by increasing fins and fin contact area to achieve, fins bottom and fin base the joint of the arc shape, is to increase the contact area.

3. Radiator bottom thickness
Radiator bottom is the function of CPU heat to a large number of suction go, if insufficient thickness of bottom, radiator of the heat capacity is insufficient, the heat transfer quantity will be limited, fin wall temperature will rise. When the computer shutdown, fan then stop running, forced convection is terminated, but CPU toshiba qosmio x505 series laptop cpu cooling fan residual heat to heat radiator and did not immediately terminated, also requires fin have enough heat capacity space will be to ensure that the processor's residual heat away, to protect the CPU. Therefore the bottom of the heat sink must ensure that is of a great enough thickness, for celeron, 2 mm ~ 3.5 mm thickness of bottom can fully satisfy endothermic demand; For Ⅲ pentium processor (copper), bottom thickness is 4 mm ~ 5.5 mm is can completely satisfy the endothermic demand; But for duron or thunderbird processor, bottom thickness need 5 mm above can meet the endothermic demand. Of course, for the same type of processor, power consumption is different, endothermic demand is also different.

4. Heat exchange area
Fin task in addition to responsible for the quantity of heat of heat source of suction to outside, another task is to provide enough heat exchange area, in the fan convection with from CPU toshiba qosmio x500 series laptop cpu cooling fan place suction to heat timely send out into the air. And is responsible for the send out quantity of heat is the main part of the radiator fins. Convection heat exchange area is larger, the greater the change quantity of heat, of course, also must cooperate with air volume air pressure are large enough fan can be achieved. So choose radiator, want to choose radiator fin piece is more dense.

Buy motherboard need to pay attention to?

Yes, the big brand products is more assured acer aspire 4320 series laptop cpu fan(at least after good, warranty convenient). But, to pay attention to is giant products, the price is higher than the other product a lot! So, my personal advice! If you abundant funds, the target is above 1000.00 motherboard word, that a line ASUS, GIGABTYE are you don't second choice. The main board of makings charge for the absolute will let you dazzle eye! The key still lies in the enterprise research and development ability strong, the main board of the support function let you use are to burn. But if you want to choose, is more practical products words! I think these a line of products, not the best choice for you! In the 500.00-1000.00 this file products! ASUS waiting for a line manufacturers because of considering the cost, in the materials you as second line reflection of Thai, ShengJi manufacturer! And the price, because the concept of brand, than the manufacturer of the product is high, and because the price of the product technology are mature, so everyone differences are not! So, also can consider to relatively large second line brand!

2. To pay attention to material

Generally a piece of onboard the acer aspire 4710 series laptop cpu fan mainest is wiring is reasonable, with makings solid! Wiring reasonable directly affect the computer each part of data information transmission rationality! On the mainboard and each control chip cooling problem! General design excellent motherboard, you can see on the mainboard parts distribution are very uniform! Won't appear that some parts are concentrated together! And the other part and very empty condition! There is between the parts go line is clear, won't appear frequent staggered situation! Materials, simple should pay attention to two pieces of (the average user attention too much, also does not have the meaning)! A piece of is to see the CPU mainboard near the number of inductance coil (enclosed inductance coil is like a small black squares, open mode is a coil). The amount of things, you can understand for multiphase power supply (a few coil is a few phase power supply)! Generally in the three-phase above! At present is to provide more CPU pure more stable current! This thing the more the better (of course, the more cost is higher, the top products for eight phase power supply)! Another block is capacitance and PCB material! PCB is a main board of foundation! PCB board is thicker, the quality of the products better, electrical properties is also more beautiful! Are generally with 6 layer above PCB board as a base plate! A good product with eight layer PCB! Most of the little water! The key is to understand the more thick, the better! As for capacitance! Now basically has kinds, a kind is the solid capacitance, one kind is liquid capacity! The former cost is very high but more stable, life is also very long! The latter although in stability and life than on the former, but the cost is very low! And good quality liquid capacity, performance also don't lose solid capacitance! You should pay attention to is the main board on the number of capacitance. Generally speaking is the more the better! Especially use aluminum shell capacitance acer aspire 4720 series laptop cpu fan ruby capacitance products is the best!

3. Extension performance

The computer is to upgrade quickly product! If choose motherboard, not funds were insufficient words! I suggest to buy time to consider upgrade question!
Mainly pay attention to motherboard acer aspire 5050 series laptop cpu fan external device interface quantity! (for example, the number of SATA interface, the number of USB, etc.) here see individual needs!

The mouse failure analysis and maintenance

The mouse hp pavilion dv6 3011so laptop keyboard failure analysis and maintenance is simple, most of the fault for interface or key bad contact, broken line, mechanical positioning system smudginess. A few fault for the mouse internal components or circuit virtual welding, it mainly exists in some inferior products, especially the light emitting diode, IC circuit damage is in the majority.

A, can not find the mouse

1, mouse completely damaged, need to replace the new mouse.
2, the mouse hp pavilion dv6 3012eg laptop keyboard and host connected a serial port or PS / 2 port bad contact, carefully pick good line, restart the can.
3, on the main board of the serial port or PS / 2 port damage, this kind of situation is very rare, if that's the case, had to replace a main board or the use of multi-function card on the serial port.
4, the mouse line contact undesirable, this kind of situation is the most common. Poor contact point in mouse internal wire and the joint of the circuit board. Fault as long as not to PS / 2 layup, general maintenance up easy. Usually because line is very short, or is mixed and disorderly and lead to the mouse line was the cause of the pulling force, the solution is to will open the mouse, then use solder iron will spot welding is good. Still have a kind of circumstance is the mouse line internal bad contact, is due to long time caused by aging cause, the fault is usually difficult to find, replace the mouse is the fastest solution.

Second, the mouse can show, but unable to move

The mouse hp pavilion dv6 3015tx laptop keyboard flexibility drops, the mouse pointer not as before follow one's inclinations, but slow response, positioning inaccurate, or simply can't move. This is mainly because the mouse in the mechanical positioning rolling shaft accumulation too much dirt and lead to drive failure, causing rolling not flexible. Maintenance of the emphasis on mouse internal X axis and Y axis of the transmission mechanism. The solution is that can open rubber ball lock plate, the mouse rolling the ball off, with a clean cloth dipped in neutral detergent for rubber ball cleaning, friction shaft, etc can be used by alcohol to scrub. Best in the axis place on drop a few sewing machine oil, but must be careful, don't flow to the friction surface and code disc gate sew the. After all the dirt removal, the mouse flexibility back again.

Third, the mouse button failure

The mouse button without action, this may be because the mouse hp pavilion dv6 3060sa laptop keyboard button and circuit boards micro switch distance too far or click on the switch after a period of use and reduced ability to rebound. Disconnect the mouse, when the mouse button below stuck on a moderate thickness of plastic sheet, thickness according to the actual need and determine, after the completion of treatment can be used

How to hide your IP address

In the dell laptop keyboard Internet, in fact hide IP benefits a lot, simple in summary there are two points: one is in the surf the net prevent invaded/attack; Two is to accelerate the speed of the open web. Of course, most people hide IP is the most main purpose is to strengthen the security of the system name, from attack.

Now almost every with the network related software provide "proxy Settings", as long as simple set the can the real IP hidden, replaced by a proxy IP. Now say to hide the real IP specific methods.

The first method is to use "QQ agency announced device XP" and "SocksCap32". First of all operation QQ agency announced device XP,dell xps 15 l502x laptop keyboard in "agent type" place Socks5 selected, and checked the right "is testing agency" option, and then click on the toolbar [read data], and the program to return to acting IP information, select a fastest proxy IP, in its click button, select "duplicate IP" the order.

The next SocksCap32 start, into the main interface, click on the [File] - [Settings] command, open the Settings dialog box, just copy the IP address of the paste into "SocksSerVer" text box, port generally do not change (as the proxy IP the support of the port and decide). Select the "Socks Version 5" and click [sure] to return to the interface program. To QQ program, for example, click on the SocksCap32 program [File] - [New] command, in "ProfileName" text box random input "QQ", and then click [Browse] button dell xps m1330 laptop keyboard specified QQ procedures in the directory, finally press [OK] button. In SocksCap32 double-click on QQ icon, testing found that QQ can normal login, display IP is just setting agent IP. If QQ can not login, explain proxy server response is slow, then as long as to choose a response speed faster acting IP can.

Assigned to

MultiProxy is to use HTTP proxy hide IP. Method is the IE browser, in the address bar lose http://www.allproxies.com/page1.html, although is full of English may be some look not to know, it doesn't matter, as long as the proxy IP dell xps m140 laptop keyboard copied to the Word, press [Ctrl + Shift + F8] key combination, put all the proxy IP outside of the content after deletion, again use "replace" function change forming such as * * *. * * *. * * *. * * * : port format. The operation is very simple, the IP and port between the two Spaces replace into ":" on it. Modification is completed, will file save into TXT file.

The next start MultiProxy program, click the interface [options] button, in "conventional choice" page "default overtime" time set longer such as "30", the other Settings remain unchanged. Switch to "proxy server list" page, and according to the lower right corner of the [menu] - [file] - [import proxy list] order, will just keep agent IP file open, at this time will pop up a "inspection agency" dialog box, press [sure], click again [sure] to return to the interface program. If just choose agent IP file unable to import to list, may exist in the file is not in conformity with the format of the IP dell xps m1530 laptop keyboard, will they change correctly, save to import after the can. Now, click on the [check all the agency] button, verification IP whether can be connected. After the inspection, click [options] button, switch to "proxy server list" page, click on the left bottom [menu] - [agent table] - [delete no response agent] command, then will ask "is sure to delete all no response agent", click on the [sure], and there is no answer agent IP after deletion, and the rest is can be connected agent IP, click on the [sure] button to return to the interface program.

Now start IE browser (don't close MultiProxy) test the, click on the [tools] - [Internet options] command, switch to "connection" page, here are two kind of situations: one kind is through the dial-up Internet access, in "dial-up connection" below selected a default dial-up connection, click the right "Settings", check the box "use a proxy server" in front of the small box, in the "address" input 127.0.0.1, in "port" input 8088 (this is MultiProxy default receiving port), and then click [senior], "for all agreement is using the same proxy server" before the small hook take out, continuous press [sure] button to exit; Another is by LAN share Internet, in the "connection" page click the dell xps m1710 laptop keyboard following [LAN Settings] button, followed by setting and as above. After the setting, login a can display IP BBS test once, can see true IP has been hidden, shows the proxy server IP.

So far has reached the hidden real IP purpose

Sata start slow reason

Problem: the author put new buy SUMSUNG HD160JJ (160 Gb SATA2, 3.0 Gb/s specifications, can backwards compatible SATA, 1.5 Gb/s) hard disk received my KM400 motherboard (VT8237 occurrence), all of the steps after the completion of the right. Boot, mainboard detection, CPU good laptop keyboard, memory, IDE equipment self-checking passed the. But the next SATA equipment cannot be passed. The system shows "Eetecting SATA Driver..." He condemned there motionless, the hard drive lamp also don't shine. First thought is the first time may detection to longer, but waited a long time before all have no action.

Analysis: connection are true, will see there is wrong. Is main board too old hard disk is too new and not compatible? But checked material, found the main board and hard disk can be combined. Material also said not a RAID,acer aspire 4810t keyboard installation system can not floppy disk loading driver, direct can use. That is when the self is revealed, and also will get through.

But even if motherboard does not support it, should also will show whether find SATA equipment. And the symptoms of eyes, like a stuck not moved. After restart, check haven't been able to change the original state. In every possible way helpless, acer aspire 5612 keyboard had to remove the hard disk going to friend's machine try. Boring room, in count data line plug in the needle, but found a could change the status quo of the problem.

To solve the problem: the data line plug a needle is between two needle a piece of plastic to squeeze get down, unlike other,acer aspire 7520 keyboard the same as the needle. This needle stick on the bottom plug, may not have conductive role. 39 needle before the IDE cable less a needle may affect data transmission, don't say it's only a few needle.

It seems the data line really have the very big quality problem. To find to mother's embroidery needle, threw the needle to get a rise. Reattach hard disks, boot try. With "du" of 1, all the self fast and smooth over, almost see SATA Driver of the self. Later the installation system, installation other application software,acer aspire one d150-1125 keyboard music, movies and operation no problems. Now has been used for more than a month, never similar problems. It seems SATA hard disk data can't be ignored key problems.
