The choose and buy memory need to pay attention to some what?

- memory chips
The most important element of a memory is samsung r25e laptop keyboard chip, the stand or fall of it for the whole memory module influence is almost decisive. Due to build memory wafer factory need to spend billions of dollars a huge sum of money, plus the production process is very precise, so the world has the ability to produce memory chip manufacturers very little, basically have: Hynix (Hynix), Samsung (eis), Qimonda (odd dream of), Micron (MeiGuang), er will reach, force crystal, promos, South Asia.
In choosing the best memory chip priority original original word chip, because these products after a wafer plant most strict inspection and test, so the most security quality. In addition, at present a lot of module manufacturers to product image unified, especially the memory chip surface's handwriting printing into their own LOGO, give consumer choose and buy some inconvenience caused. In fact, as long as it is well-known module manufacturers of products, user can rest assured the choose and buy, but don't covet is cheap and buy off-brand small factory products.

PCB -
PCB circuit board is an important part of a memory chip load, its important index layer number is how much and samsung r26 laptop keyboard wiring process. For the mainstream DDR2 memory speaking, 6 layer circuit board is the most basic configuration, a lot of high standard, high frequency products use even eight layer PCB circuit boards. Generally speaking, layer number of PCB, the more the signal anti-jamming ability is stronger, the more help to memory stability.
In addition, the PCB surface line layout is very important also, according to the international electrical learn design specification requirements, PCB surface line must use a 135 degree Angle processing, and to ensure that lead length is consistent, local should use biker wiring.

The work took gold finger
PCB lower for a row of gold plated contact, scientific name is called "golden finger", don't look down upon these glittering contact, if one of the root falls out of the ear or oxidation, it may cause some fault hidden trouble.
At present gold finger production samsung r26s laptop keyboard process has two kinds, one kind is electric plating, and the other is the chemical plating. Electric gold-plated than chemical plating gold layer thicker, can improve the abrasion resistance and anti oxidation resistance.

- capacitance/resistance
In PCB gold finger above and chip around there will be some small electronic components, they are capacitance and resistance. Say commonly, the more resistance and capacitance for signal transmission samsung r29 laptop keyboard stability is good, especially in chip next to the efficacy capacitance and the first root gold hand guide feet filter capacitance.

Core i7 notebook optimization

Recently a friend bought a M17x notebook dell vostro 1700 laptop cpu cooling fan, the core i7 four nuclear processor, 4 gb memory and Geforce GTX 260 m video card. So powerful configuration, but playing games, editing video on is not smooth, and see a movie will appear popping, actually core i7 notebook will optimization, to dig potential performance. The following method to optimize core i7 notebook can also be applied to other type core i7 notebook.

Open intelligent acceleration technology
I7 core processor support Intel gruppo frequency acceleration technology, with the aid of Turbo Boost program, can provide powerful performance mining model, but dell i7 notebook and no preloaded Turbo Boost procedures, login Intel official web site, download and install TurboBoost program, the overall performance will be a lot of amplitude ascension.

2, open i7 four nuclear instruction
I7 core processor has four nuclear core, but most of the software dell vostro 3700 series laptop cpu cooling fan is not about four nuclear instruction optimization, but with RHTW software, can let the common software support four nuclear instruction, the four nuclear CPU performance improvements is up to 3.5 times. Download and execution RHTW software program, click on the "Next" button, it will pop up an ms-dos window, and then start scanning CPU hardware resources, and write the corresponding driving instruction to optimize CPU, write after the completion of automatic exit ms-dos window, it established a multithreaded mapping mechanism.

3, loading Win7 decoder
M17x notebook installed Win7, in play high-definition movie, speed performance is not ideal, at this time should be with the aid of the third party decoder, can improve hd decoding efficiency. To Win7codecs decoding package, for example, download and install decoding bag.

And then run the media player, without any Settings,dell latitude d531 laptop cpu cooling fan the program the default configuration, can smooth high-definition decoding.

4, solve problems popping sound card
M17x notebook in the movies, always can appear popping problems, solution is to enter the registry editor, in turn into HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentCon - trolSet \ services \ Audiosrv, double click on the right side of the window "DependOnService" name, will numerical data of "MMCSS" deleted.

Save out and in the "run" window input msconfig orders and enter, switch to "service" label, find the "Multimedia Class Scheduler" option, and its front hook can be removed.

Configuration and high notebook not for system optimization, will also does not work smooth, core i7 notebook, too, so properly handle between the notebook dell alienware m15x series laptop cpu cooling fan set and management is the guarantee of the basic operation flow.

CPU radiator fault caused by the bad

Fault phenomenon:

When use, machine frequent a toshiba satellite m100 laptop cpu cooling fan blue Windows warning window, then appear crash fault.

Failure analysis:

Due to the warning content for the messy code, appear before failure and just installed a download them from the Internet application software, the doubt is the software with a virus, then, will be installed software delete and separately using KV300, KILL98 and rising antivirus software such as check, antivirus operation, all did not discover the virus is found. Shutdown and restart, about 4 minutes later, once again appear afore-mentioned phenomenon,toshiba satellite m35 series laptop cpu cooling fan repeated several times this is still true. In order to eliminate the possibility of viruses, format hard disk and reinstall the system. When using Windows

95 the setup disk for installation, the installation is complete, the above phenomenon to appear, make installation cannot normally completes.

Troubleshooting:

Fine a thinking, feeling the fault is not like caused by viruses, because every time the machine to boot, had just begun to work normally, only in a few minutes later to appear the phenomenon of crash, it appears that some of the machine and hardware, especially the CPU chip temperature relevant. Shutdown, open chassis inspection, when touch CPU chip radiator, feel temperature is very high, very hot, which is obviously not normal, doubt is CPU chip or its radiator on the exhaust fan is not normal. In the case cover open cases start machine, right now found, the CPU chip radiator of exhaust fan speed is very slow, has lost the normal cooling function. Shutdown, the exhaust fan to be removed, hand toggle blade, feel blade rotation is not flexible, therefore, with flat screwdriver inserted blade root of the gap in under upward become warped, will the whole blade and fan toshiba satellite m30 series laptop cpu cooling fan base separation, over blade, see in the blade of the central part has a use several small arc magnet surrounded the round cover form, obviously, this is the fan motor rotor and stator is and fan base fixed together a miniature winding, if the fan blade and fan base together, the miniature winding just inserted in the internal rotor. Further observation found that the top of the shaft in the stator and rotor conterminous bearing parts stick some dry black sludge, respectively with gauze the erasing clean, again on the point into several drop senior watch lubricating oil, and then will fan and fan base realignment together, at this time, it gently moving blade, blade can easily turn. To restore the exhaust fan installed on the CPU radiator, and electrical test, can see the blade rotation fast, power on 10 minutes, touch the CPU chip, feel the temperature only lukewarm state that fan cooling function has been fully recovered. Cover good host chassis, restarting and reinstall Windows

95 system, everything is normal, long time continuous work, the fault also does not appear again.

Fault description:

The fault system CPU radiator of exhaust fan lubrication is bad, make blade rotational resistance increases, lead to blade speed is low and lose heat dissipation function, so as to make CPU toshiba satellite m105 laptop cpu cooling fan on a few minutes later because of high temperature and into the self protection condition, appear the phenomenon of crash.

Blank screen fault how to deal with

Display failure cause computer blank screen failure to how to solve? Below is the specific analysis:

First of all, for the main computer ibm lenovo thinkpad g450m series laptop cpu cooling fan fault caused by the display blank screen fault we can from the following train of thought to solution:

1. Check parts installation quality
When you in the assembly computer or replacement parts occurs when blank screen failure, you should first check your installation quality accessories. For example memory-chip installation is correct if motherboard slot good contacts, graphics card and card is installed in place, BIOS setup and the related on the mainboard jump line choice is correct, but carefully see related interface card set instructions, and inspection of key board their own quality problems on the mainboard ibm lenovo thinkpad g455 series laptop cpu cooling fan and relevant slots and card "golden finger" whether there is a foreign body parts and the dirt that pollution is also very necessary.

2. Listening view color distinguishes the fault
Computer appear blank screen fault more time on performance after host panel light, built-in fan normal rotation, but appears the PC speaker alarm sound; Or chassis internal such as hard disk and other related equipment normal self, but display no display. Then according to the above method in addition to repair, but the more important thing is to learn to distinguish PC speaker error rule to distinguish fault, in addition to observe malfunction host or display various indicator to judge the situation or fault is also very good.
For example, the host normal self, but display appear "blank screen" fault, for this kind of trouble we will focus on the motherboard - VGA card - display connecting display this approach up consideration. First can check the display power ibm lenovo thinkpad g550 series laptop cpu cooling fan light is light, such as normal, but key adjust brightness, contrast button, eliminate "common" this kind of false blank screen fault. If no problem, then you can focus check the main VGA card to display the connecting cables have problems and cable plug inside pointer whether there is inclined fracture and whether and VGA card compact connection xp system download also can connect the cable joint take down, see display can normal show bright or will display even to other host try, so as to judge the fault location is from host or display own cause.

Be like again, to display blank screen and host in a loud speaker long, two or three short bumming or continuous bumming that VGA card and onboard the connections between have questions or graphics card and display the connection between has a problem, you can check the key slots contact is good groove if there is a foreign body and replaceable graphics to try, if no better, but preliminary showed that problem on the mainboard, can get other card on the mainboard try. Be like again, consecutive long sound chirping, it mostly show that memory bank have a problem, can the inspection of key memory and memory slot installation contact conditions.ibm lenovo thinkpad sl300 series laptop cpu cooling fan If machines talking a continuous short sound, the machine has slight short circuit phenomenon, usable minimum system method and exclusive method to solve the problem, until find short circuit parts. In addition, if you hear two sound short bumming, the mainboard or graphics card or display the likelihood has a problem, not connect display if or so sing, the VGA card parts existing problems, such as a sound... long-short-long-short...), the display end has a problem.

To display their own cause blank screen fault is concerned, we mainly from the following to provide you with more specific maintenance train of thought

1. Display blank screen quick maintenance
If the display device without any display, eliminate the host of reasons, then can check whether because the voltage is too high or too low cause display protection circuit work, you can check the accelerate polar voltage is normal or not. In addition, the key ibm lenovo thinkpad sl400 series laptop cpu cooling fan is to check the following problems parts, such as look at whether the fuse blown fuse, rectifier bridge switch tube whether the breakdown, current limiting protection resistance is burn out, etc., these parts sometimes from the outside can see its burned black and fault phenomenon. Then key inspection line output tube, transformer, low-frequency rectifier tube, high frequency rectifier for key parts such as whether there are damaged or performance decline or virtual welding, etc, general display blank screen fault you as long as it can quickly to the instant solutions.

Tube and power supply circuit fault judgment
Tube and power supply circuit is not normal also can cause display power up no grating blank screen fault. Then we can check whether the tube filament light, with meter to measure the filament power supply circuit see its filament voltage is normal or not. In addition if the filament current blocking the need to change the good filament current limiting resistor can be, if found tube filament broken, then the need to change the picture tube. If above normal, we can be key ibm lenovo thinkpad sl400c series laptop cpu cooling fan to check tube accelerate polar voltage is normal or not, especially accelerate polar voltage attachment fault is a cause of this kind of failure of the primary, replace the can. If there is high pressure, we may consider mainly change line output transformer (ignition coil) try ghost xp sp3, this part of the damage was caused by the fault of one of the main display blank screen. In addition to the above in repair at the same time we also can check the cathode voltage and apparent put voltage is normal or not, if apparent put voltage didn't add or its voltage doesn't normal also causes display power up no grating and one of the important reasons for blank screen.
