A, network own problem
You want to connect target dell inspiron 1525 series laptop cpu cooling fan
web site is located server bandwidth or inadequate or excessive load. Processing way is very simple, please change the time again or change the target web site.
Second, the screen wire to wire speed slow
We know, twisted pair consists of four to line according to strict rules tightly twisted and together, to reduce crosstalk and the influence of the background noise. At the same time, in T568A standards and T568B standard using only the twisted pair of 1, 2, and 3, 6 four line, among them, used to send 1, 2, 3, 6 for receiving, and 1, 2 must be from a wound to, 3, 6 must come from a wound to. Only in this way, can maximum limit avoids crosstalk, guarantee the data transmission. I am in the discovery in practice do not press the right standard (T586A, T586B) of the production line, there are a lot of hidden trouble. Performance: a situation is started using wire speed is slow; Another kind of circumstance is began to wire speed normal, but after a period of time, wire speed slow. After a kind of circumstance in the desktop computer performance is very obvious, but with a laptop computer inspection wire speed but performance is normal. For this problem I found after many years practice, because you did not press the right standard made by line of wire speed slow also at the same time and the quality of the network card about. General desk computer interfaces as the performance of the notebook computer, therefore, in exchange method debugging, use notebook computer asus u50f series laptop cpu fan
detection wire speed normal and can't rule out according to the standard reticle don't make this a problem exists. We now requires all presses the T586A, T586B standard to suppress line, in the test failure can't all laptops instead of desktop computer.
Third, existing in the network circuit leads to wire speed slow
When the network involved in the node number is not many, the structure is not very complex, this kind of phenomenon is common seldom occurs. But in some more complex network, often have extra spare circuit, such as inadvertently even when the constitutes a loop. Such as line from the network center received computer one room, again from the computer one room received computer 2 rooms. At the same time from the network center and have a spare circuit connected to the computer two room, if the lines at the same time on, is a circuit, the packet will continue to send and check data, thus affecting the whole wire speed. This kind of situation is difficult to find. To avoid this kind of circumstance happening, we need in laying the line must develop good habits: line a clear label,asus g72gx series laptop cpu fan
a spare circuit place to do records. When suspected such fault occurs, generally USES subarea-subsection gradually eliminating methods.
Four, network equipment hardware fault caused by the broadcast storm and lead to wire speed slow
As the main means to find the unknown equipment, broadcast in the network plays a very important role. However, with the increase of computer quantity in network, the number of broadcast packets could sharply increase. When the number of broadcast packets reached 30%, network transmission efficiency will be decreased obviously. When nic or network equipment damage, will keep sending broadcast packets, leading to the broadcast storm, so that network communication paralysed. Therefore, when the network equipment hardware failure can also cause wire speed slow. When suspected of such failure, you can use displacement method to replace hub or switch to eliminate set line equipment failure. If these equipment without fault, turn off the hub or switch power supply, under DOS with "Ping" command to one involved in the computer test, find a fault nic computer acer aspire 5738 series laptop fan
, change new nic can restore normal speeds. Nic, hub and exchange is the most prone to failure cause wire speed slow equipment.
Five, the network a port to form the bottleneck lead to wire speed slow
In fact, the router wan ports and LAN port, switch port, hub port and server nic may become network bottleneck. When the wire speed slow, we can use in the network peak time, the use of network management software view routers, switches, server port data flow; Also can use Netstat order statistics each port data flow. Hereby confirms network data flow bottleneck position, try to increase the bandwidth. The specific method are many, such as replacement server nic for 100 m or 1000 m, install multiple network card and the division of more than one VLAN, change the router configuration to increase bandwidth to wait, can effectively alleviate network bottleneck, can maximize data transmission speed.
Six, the influence of worm virus to wire speed slow
Through the E-mail sends out worms virus on the acer aspire 1360 laptop fan
influence of network speed is more and more serious, great harmfulness. This virus causes infected users as long as the Internet is kept to outgoing mail, virus select users personal computer of random document attached to the users of the machine address book random address on the post. Hundreds of thousands of this kind of junk mail some lined up outside to send, some and batch by batch returned to pile on the server. Cause individual backbone Internet appear obvious congestion, wire speed significantly slow, make the LAN to paralysis. Therefore, we must upgrade anti-virus software used in time, The computer will timely upgrades, installation system patch, and at the same time, discharge unnecessary service, shut down unnecessary port, in order to improve the reliability and safety of the system.
Seven, firewall use too much
The firewall can also lead to excessive use of network speed slow, treatment method need not say more, discharge the unnecessary firewall only retains a powerful enough to.
Eight, the system resources
You may loading too much use program runs in the background, please reasonable loading software or delete useless acer aspire 3620 series laptop fan
programs and documents, the resources empty out, in order to achieve the purpose of improving network speed.

I3, i5 i7, the difference between the processor
For toshiba satellite l675-s7018 laptop cpu fan
the players for friends, respectively i3 / i5 / i7 affirmation is not a problem, if the pouch full of words, may be directly on the i7 980 x. But more ordinary users in the CuanJi or when the choose and buy will still have a lot of doubt, they only have to when the choose and buy will meet how to distinguish i3 / i5 / i7 this kind of problem.
As there are so many ordinary users don't know i7 also have two kinds of interface, the i5 can also be used for H55 on the mainboard feel very surprised, i3 collocation P55 output problem is full of doubt... So a variety of vary;
I7 support 3 channel i5, i3 does not support
I7 QPI bus technology i5, i3 use SMT
I7 4 nuclear 8 thread i5 4 nuclear 4 thread i3 dual-core 4 thread
I7 1366 interface i5, i3 1156 interface
I7 X58 chip (double chip) i5, i3 P55 H57 H55 chip (single chip, integration of the previous north and south bridge function)
I7 current i7 no integrated GPU i5, i3 new out i5 6 * * series and i3 integrated the GPU
I7 four nuclear and support hyper-threading i5 four nuclear, does not support super
I7, i5 support gruppo frequency technology (that is, in the toshiba satellite c630 series laptop cpu fan operation of certain programs than the default frequency higher) i3 does not support the technology
First explain "I7 1366 interface i5, i3 1156 interface" this article, I7 9 series CPU has 1366 stitch (each root stitch can be understood as a root of the circuit connection), so to have 1366 interface X58 motherboard; I7 eight series, i5, i3 are 1156 stitch, so need to have 1156 interface P55, H57, H55 motherboard
I7 support 3 channel is to point to it supports memory composition three-channel (at least three root memory), can make the performance get corresponding ascend; I5, i3 does not support means they only support dual channel memory, rather than three-channel speaking, memory performance to the corresponding weaken.toshiba satellite c640 series laptop cpu fan But not all i7 support three-channel, only i7 9 series is support three-channel (such as i7 920), and i7 8 series only support dual channel (such as i7 860). But increase a memory channel for the ascension of the system performance is relatively weak, unless the CPU for very tall to the requirement of data memory, double channel has a tight comparison, so i7 9 series is not better than i7 8 series obvious advantages
"I7 using QPI bus technology" and "i7 X58 chip (double chip) i5, i3 P55 H57 H55 chip (single chip, integration of the previous north and south bridge function)" the two sentence is corresponding relation, with i7, before the Intel 775 series CPU have forepart bus design, Intel motherboard, occurrence, agp design, but also correspond to one forepart bus, CPU through the front end bus and memory for data exchange, it will form bigger transmission bottleneck. Series 1366 CPU first cancelled forepart bus this traditional design, but the CPU internal integrated the memory controller, called QPI bus, not through the chipset direct access memory, memory performance greatly improved, but the main board toshiba satellite l20 series laptop cpu fan top still have occurrence, chipset double chip; For series 1156 CPU, simply even PCI - E controller is integrated into the CPU internal, make chipset work were grabbed off the CPU, so P55, such as H55 motherboard above occurrence of only (and do not let the occurrence of) the single chip. QPI and SMT is not a kind of concept, no comparability, SMT means "synchronous multithreading"
"I7 4 nuclear 8 thread i5 4 nuclear 4 thread i3 dual-core 4 thread" and "i7 four nuclear and support hyper-threading i5 four nuclear, does not support hyper-threading" two is a causal relationship. I7, i3, i5 6 series support hyper-threading technology, i5 7 series do not support, the so-called hyper-threading refers to the CPU core idle resources make to simulate a core that performance improved significantly. Hyper-threading make a core can simulate into two logical core, called double thread. So i7 four nuclear support hyper-threading is one of the four nuclear eight threads, i5 7 series four toshiba satellite l30 series laptop cpu fan nuclear does not support hyper-threading, is one of the four nuclear four threads, i3 dual-core, i5 dual-core support hyper-threading, dual-core is four thread. But although hyper-threading can make CPU core virtual increase a times, but the core of the simulation with the real physical core than up still have a certain performance gap, so the same frequency i3 performance is not beyond i5 7 series

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.

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.

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
