How to identify the quality of PC hardware

Eye view: from the hardware itself, identify

A. From the packaging anti-counterfeit labels do not

Purchase of hardware products, the first the first is to see product packaging, Kingston (Kingston) memory, for example, on January 10, 2005, in the domestic distribution Kingston products, all using the new "nano refractive logo, it is said security standard similar to the laser technology may be no fraud, this anti-counterfeiting stickers will replace two years of phone messages like pseudo labels, after genuine Kingston memory can be seen in the striking position, and without through a third party means such as telephone, Lenovo 3000 N500 Battery SMS to verify authenticity.

For other products such as motherboards, graphics cards, optical drives, etc., used packaging on the box generally have 800 other free consultation phone manufacturers of products via the telephone consultation is genuine. Such as SONY magneto-optical storage products sold in China (CDRW, DVDRW, etc.), licensed affixed with blue security label of the China Quality Inspection Association.

Label stickers from the two-tier structure, opened the label surface in the second layer of the sticker on the can see the security code, but the label on parallel imports and counterfeit security code to be investigated to reveal the surface immediately after purchase, call security on the label free telephone 8008106046, query the purchase of a product's authenticity. In addition, the SONY licensed affixed with a security label of "Sony original power of the rich agent". This is an important method of identification licensed, parallel imports and fakes (Special note: fake parallel also labeled anti-counterfeit trademark).

Two. To see the authenticity of the chip itself

A lot of JS on the product packaging is too true, and many users have to buy bulk products (such as bulk the L08S6C02 Battery CPU, memory and hard disk, etc.), resulting in the user identification can not be carried out through the packaging, so from the quality of the hardware itself process to identify. Such as CPU, memory and other hardware because of its core chip is exposed, which often is the product of JS the most easy to polish or false. We are very easy to use eye identification, the CPU, for example, many users buy the INTEL the P4 3.0G PACKER products, paid their money, took the goods, even carry home a parts CPU.

We take a look at this P4 3.0G PACKER the CPU in the product box label, indicating the secondary cache of 512K, this is entirely correct, but to open the package, look at the surface of the CPU above identifies the L2 cache has is 1M. The Earth all know, the P4 3.0GC (FSB800), L2 cache is only 512K, and thus, we can conclude that this is a fake PACKER CPU.

AMD XP2500 +, for example, in fact, counterfeit XP 2500 + Thorton core 2000 + polished from its core in Baton 2500 + the same, but the IBM ThinkPad Z61p Battery secondary cache is half closed, as 256KB. The original counterfeit method is to open another 256KB cache CPU surface connected by a pencil or silver paint L2 Jinqiao, so a price of only $ 400 more than the Thorton core XP 2000 + suddenly became a value of more than 700 yuan XP Barton2500 + JS thereon to seek nearly 200 $ profits. In addition, fake XP 2500 + L2 Jinqiao move hands and feet, so under normal circumstances JS fragile sign the key areas covered tightly.

Hynix modern memory, for example, now The hynix modern memory is almost nine out of ten is polished false note. We take a genuine and a polished hynix memory contrast, the surface, it seems not much different.

But as long as you look carefully, a unique circular pits on the corner of memory particles. Polished particles, the pit is illuminated, the particle surface is frosted feeling.

HP Compaq Business Notebook 2510p Adapter Memory polished coated with a layer of black paint, so the pit was almost filled, and with your fingers scraping the laser etching of the above will fall off, memory polished method is relatively simple, covering the coating after their own secondary laser etching, the implementation of home eye can easily see it.

3. Look at quality from the PCB layout

Graphics cards, motherboards and other products due to the heat sink core covering the time of purchase can not disassemble the heat sink, we identify from the above method, for its own PCB layout is reasonable, but also identify an important means of quality. Such as the one with the specifications, the same model, used the same chip graphics card, genuine public board Dell Inspiron 1521 charger PCB design, and some fake control costs, is used a non-public board design. "Non-public board" more time just for the product of the birth of the "low cost" or promotional needs. For example, understanding of the PCB due to a lot of people would like to wish to stay in the level of "a certain graphics card with the N-layer PCB, the PCB layers as possible like the JS will therefore have a chance ... a graphics card ... but obviously only with a four layer PCB, JS has chosen to say this card with a 6 layer PCB.

To identify the quality of the PCB, we have to start from subtle. For example, by oxidation of the observation blind hole and solder around, we can know the materials of the PCB, good or bad; observed the transmittance of the edge of the PCB, we can approximate thickness of the PCB. Of course, if the business can provide multiple different graphics cards in kind, then, then the identification of the work will be much easier to expand the Such as low-pass filter circuit can not be ignored, low-pass filter circuit (low pass filter circuit close to the graphics VGA output interface is composed of a lot of capacitance and inductance circuit, used to improve the stability of the display signals and, ultimately, the quality of output screen), few Dell Inspiron 1525 Adapter consumers pay attention to it, does have a lot of graphics card manufacturers to squeeze profit on him.

In addition, some motherboards fake products, using only the two-phase power design, genuine high-end products with 3-phase or 4 phase power design.

Or some low-quality products with low-quality capacitors and other components, so that will not only allow the board can not overclock, and even frequent crashes during normal operation. There are some fake products, even though the specifications are the same, but omitted some of the features, such as used to support three memory slots, and only two. Low BIOS version as well as low-end integrated sound card, or even omitted, such as IBM Laptop Batteries network cards, 1394, and additional features (if genuine any).

Automotive interior maintenance and cleaning

Driving will find: the trace of soot shells fall on the mat, horizontal seat surface stains inside the door side of the Parti shoe print. Automotive interior maintenance methods? Beauty experts pointed out that the maintenance of automotive interiors in many ways, today summed up a number of EliteBook 8530P Battery automotive interior maintenance methods.

One of the automotive interior maintenance methods: seat Maintenance

At present, the seat is basically divided into the leather seats and velvet seats two, its automotive interiors and maintenance methods are not the same.

Maintenance methods for automotive interiors leather seats:

The limousine is more than the leather seats, there are many drivers to install their own leather seats, remarkable comfort, the luxurious elegance, and longer service life. The leather is a natural thing, and maintenance up naturally can not light depending on the. HP Compaq 6715b Battery Chemical cleaning agents can not just spray up, should be used in strong alkaline cleaning agents, such as soap and water and the like, washed cotton paper towels to dry. Daily car interior maintenance, in addition to well known to avoid sharp objects to scratch the leather, but also pay attention to dust-proof sunscreen. All-pervasive dust, siphoning off natural oils in the leather, it will become a dry skin. Burning strong sunlight causes human skin aging, it is equally applicable to leather seats. Therefore, the maintenance of leather seats, car interiors and maintenance methods to do the following:

Lenovo 3000 G530 Battery Car leather as much as possible to the location of two feet from the heat source, such as to cause a leather chapped from the heat source too close to;
Not a long exposure to sun exposure, avoid leather fade, especially open roadster friends, not one o'clock in order to pull the wind, loss of skin I..
Regular implementation of cleaning and maintenance, weekly use of vacuum to the Solar Panel Charger for Laptop flue dust;
After cleaning do not use hair dryer to quickly dry the leather, the application of tissue paper or soft towel to avoid scratching the leather to dry naturally in the cool air.
Do not use chemical cleaning agents to clean. And less so-called leather protective agent, protective agent will make the leather to the creation of dependency, such as to stop using leather is dark.

Velvet seats, car interiors and maintenance methods:

As for the seat of textile fabrics, automotive interiors and maintenance methods are relatively simple. Woven velvet seats are not dirty, the available long-haired brush and strong suction vacuum cleaner with the side brush seating surfaces, while the vacuum cleaner suction to suck the dirt out. For particularly dirty seats, car interiors and latitude 120l Battery maintenance methods will be carried out following several steps: First, brush cleaning dirty local (such as large stains, garbage, etc.), then with a clean cloth dipped in a small amount of neutral detergent solution, fully wipe the seat surface (note that the cloth must be wrung out) in the case of dry and wet, and finally again with a vacuum cleaner to clean the seat and eliminate excess water. Automotive interior maintenance of good.

Transparent soap to clean leather seats, you know this car interior maintenance?

Transparent soap, cleaning leather seats, car interiors and maintenance methods specific steps are: clean soft towel with warm water to soak the soap evenly hit in the towel, then gently wipe the seat (folds repeatedly wipe). At this point, if the towel becomes dirty, proof of decontamination have a significant effect. Finished with the mop the soap ventilation to dry, soap-free cleaning after a wet towel to wipe twice then. This decontamination method, the Dell inspiron 1564 Battery leather clean and fluffy, fresh as ever. This law also applies to the door trim and instrument panel at the plastic parts. The reason is that the soap (soap) decontamination, and the human skin to stimulate more practical leather items.

Automotive Interior Maintenance II: carpet cleaning

Inside the car most likely to dirty carpets, vacuum cleaner with brush head maintenance of automotive interiors, dirty carpets do not look so dirty. For more dirty some of the carpet, automotive interiors and maintenance methods can only use a special detergent.

The two dust before the detergent first, then spray the right amount of detergent, scrub clean with a brush, and finally the excess detergent siphoning off on it with a clean rag, automotive interiors and maintenance methods washed the carpet both clean and any connection with previous soft. Most in need of attention is the carpet is not completely into the water to soak scrub, on the one hand, will destroy the carpet internal bonding of the layers of different materials, on the other hand makes the NIKON Battery Grip carpet can not be dry for a long time to affect the results, causing the car wet. Carpet cleaning and is more trouble, it is recommended that we insist on using the best mat if the mat is not dirty, get outside the car to beat on you.

TSI engine to reduce oil elimination and maintenance

Some people say 5000 km maintenance of domestic joint venture of Japanese cars in order to make more money, perhaps this is why, but have to admit that yes, the Japanese car with low oil consumption, and the degree of deterioration of oil quality oil compared to other cars low degree of quality deterioration, and why domestic joint venture of Japanese cars or a request for each driving three months or 5000 km maintenance?

Has also been tested Lenovo 41U3198 Battery Shell's fully synthetic motor oil, is a Japanese brand OEM's original oil 5W-30 oil also played a coke and sludge, after the Japanese car traveling 7500 km, traveling time interval is probably about half a year. After honestly in accordance with the maintenance of 5000 km standard maintenance, up to more than 6000 km.

Why is part of the NIKON Battery Grip TSI engine oil consumption is too large manufacturers require maintenance interval mileage still long? From the engine and oil quality, which should not be a problem, but the reality for the car situation, you riders have the final say. Does not rule out taking it every really ran the 7500 oil consumption, but who checked it?

Lenovo 3000 G530 Battery TSI engine operating temperature is relatively high, the probability of such oil evaporated into the gas will be higher than the NA engine, the crankcase ventilation system may will the oil steam sucked into the combustion chamber burned. The consequences have been caused by the intake system more coke, take apart and wash into the manifold and the intake valve is mostly because of this.

TSI engine because the temperature is higher, so the assembly space may not be like a regular NA engine is small, this piston reciprocating motion of the cylinder wall on the splash lubricating oil can not blow as clean as possible, so that is also part of the reason Lenovo L08S6C02 Battery oil consumption.

The engine assembly process is a bit rough, oil consumption through the cylinder wall, valve oil seals the crankcase ventilation system oil consumption will increase.

High-speed state, the oil consumption even NA engine also significantly increased.

Some customers say the old Passat 1.8T, oil consumption on little problems. The modern oil viscosity is low, the pursuit of ultra-low fuel consumption and minimize the resistance of the engine running, the oil backwards related to water like this, or the increase in oil consumption is also one of the reasons Toyota 5W- 20 oil is also a lot of riders reflect oil consumption.

Maintenance cycle of misunderstanding, in fact, in the capital, NIKON EN-EL3 battery blocking stop traffic, whether it is 7500 or 10,000 or 15,000 km warranty is not very appropriate.

TSI engine oil consumption more than 7500 km within the 1L comrades please raise your hands! For the family car, or earnest recommendations to the part of the car riders:

How many kilometers of maintenance is your choice, if the proposal is also OK, or travel 5000 km or six months, to be replaced at least once oil or travel necessary to check the oil stock of more than 2000 kilometers! Regular inspection is better than the engine took good.

If you choose 20 or 30 oil, we recommend that you consider the 40 oil, of course, this may affect your OLYMPUS LI-30B battery driving pleasure, or increase in fuel consumption, but may be able to reduce engine oil consumption, reduce engine wear.

If you want high speed, do not throttle in the end, wait for them to his feet to kick the tank, be sure to control the speed, as turbo continuous high speed, that the exhaust pipe is red, engine parts, the load will increase, certainly will affect the engine life.

If you want high-speed driving, be sure starting the margin of the first check the oil, check the oil margin return.

Accept the fact of oil consumption, JVC BN-VF815 battery vehicle spare a barrel of oil, a good habit to develop is often yourself to check to ensure the normal use of vehicles.
