Application of skills in production and maintenance of the eight issues Notebook
1, laptop repair course simply joke
In my opinion, outside the so-called laptop repair course, there is the joke then. Do not want to bear the loss, they do not want to spend more time, you think it Dell Inspiron 6400 Battery, what kind of notebook motherboard repair technician?
Techniques require repeated long-term accumulation of practical experience required
Take me for instance, I train an apprentice in a factory which is not fax capable of, at most, also pointing a number of fur effort. After all, I have the skills and experience, are explored on their own out of step by step, all at once passed to others, how I mix? I also spend quite as out on the training of people who feel sad - not only spent the money, also learned nothing.
2, is now bigger and lighter notebooks, growing in thin, this is not a good thing
The book is the quest for light, growing in thin, this is not a good thing. Do light notebook, do thin, which means doing a small notebook motherboard, do thin. Notebook motherboard is small, but above the chip and board layout will not change within a few. As a result, it created a "plate-step line of extreme-intensive" and "all kinds of chips from the compact," and so on.
Handling of the notebook on my motherboard which, thin board the highest failure rate, the basic are "board deformation" symptoms. "Board deformation" will lead directly to notebook performance instability, specifically what kind of fault occurs, that really was quite hard, but the maintenance of the result is positive - can not repair, you must replace the motherboard.
3, the more thin and light notebook motherboard the more compact the higher density chips
Notebook motherboard do small, above the high density chips. Some small chips emit a high heat, the heat will affect the surrounding "FET." "FET" generally used to control the creation or transformation of some of the operating voltage, if it is affected, can lead to short-circuit board. Once the circuit board, the problem would be bigger. It will not stop power-and kept in the boot, the final burning of the processor and other components.
Therefore, the notebook computer's motherboard is not as small as possible, so the heat will only increase the burden on the Main Board, increased risk of short circuit the motherboard. We know, ThinkPad X60s is the best brand of small size models. It uses the Intel Ultra Low Voltage processor, and strictly control the internal operating temperature, greatly reducing the possibility of failure - that is, "Why the low frequency ultra-low voltage processors, but they sell a higher price" because of 1. Of course, this is only my opinion more one-sided, and now notebook changing production process, "taking into account security and thin," it is not inconceivable.
4, notebook manufacturers reduce production costs, the factory can only cut corners notebook
At present, the major notebook manufacturers are frantically grabbing low-end market share. Want to attack the low end, we must reduce production costs. Therefore, the notebook company in time to the factory orders, the very low prices is low. Our factory notebook motherboard, the production cost of 1,000 yuan a piece of board, there can only earn 1 dollar big Dell Inspiron 8600 Battery - this kind of thing was going out, who would believe?
Laptop notebook manufacturers reduce production costs can only cut corners plant
However, the plant to pull in big clients still will take orders. But we can not lose money producing it? Therefore, the emergence of the "improvement board" to be used. It plainly, the fact that jerry-building. For example: a memory-voltage lines, which should use 30 capacitors. However, if the capacitance of only 12 words, the same can work. In this way, we will save 18 capacitors. A memory capacitor voltage line 18 provinces, a motherboard will save more material.
There is meant to be used better quality materials, in order to reduce production costs, now get a bargain instead. In this way, the factory will then save a very substantial funding. However, notebook motherboards are much cheaper because of the use of materials, and an "unstable" and so on, eventually the victim or the purchase of notebook consumers.
5, this is a easy for everyone to negligence, it will become a major problem of maintenance
In general, notebook manufacturers and dealers will not tell the consumer notebook, the notebook is used for "on-board memory" or "extended memory." The so-called "on-board memory", in short, direct soldering on the motherboard's memory. The so-called "extended memory", in short, are free to plug in memory.
A "memory board" design board is very unstable
In my experience, the use of "on-board memory" design motherboard very unstable and very prone to blue screen, Huaping and black and so on; with "extended memory" design of the board more stable, probably more than a "on-board memory "Design of the board stability of 10.
The handling of the notebook on my motherboard which, as long as a "memory board" design, and memory failure, it can be declared abandoned the basic. Therefore, I recommend buying the notebook, be sure to ask clear, "This machine is used onboard memory or extended Sony VGP-BPS5 Battery"
6, What to choose integrated graphics, what to choose discrete graphics
Here, we have to discuss is "What to choose integrated graphics, what to choose an independent graphics card." See this, then you may have to laugh at me - the performance of discrete graphics N times more powerful than the integrated graphics, of course, as long as the money to buy a separate graphics card. In fact, things are not so simple.
Some notebook graphics card is soldered to the motherboard is difficult to maintain the event of a failure
In general, notebook manufacturers and dealers will not tell the consumer notebook, this notebook discrete graphics are "welded on the motherboard", or "free to plug in." Some notebook discrete graphics welded directly to the motherboard, though with the same use, but there is a high failure risks - if not Huaping, the screen display is indeed better than the integrated graphics; Once Huaping and a black screen, motherboard directly followed scrapped it.
This motherboard failures are difficult to judge is the graphics card is damaged, or memory corruption. In the factory is almost impossible to check out, because engineers did not have time for you to take check each line; on the outside of the maintenance points, and can not get out of check, because not the technical requirements. Moreover, even if the replacement card and the memory does not necessarily solve the problem, can give you to swap out other illnesses.
Therefore, if the money, they buy "free to plug the" independence were Notebook; if no money, she bought an integrated bar - designed motherboard with integrated graphics, stability, independence explicit than the board several times higher. Huaping and black even if the phenomenon occurs, at most, is another memory, another North Bridge or something.
I use the laptop is the Founder H240D, had bought the time spent 7,300 yuan. But I almost always regarded it as a desktop machine, and it is somewhat ruined things. If you buy a computer, do not need to move around, or a desktop benefits; If you buy a computer HP pavilion dv9000 battery is a "lightweight portable", it would have to choose a notebook.
Personally, I think, 7000 Element - notebook between 8500 yuan very good. The price of notebooks, generally not in the production process corners, and the quality are good. Of course, if you more money, then better to buy high-end products. Although the laptop price is now lower, but the real "good product" or expensive.
7, the biggest advantage of notebooks is moving, but often also affect the safety of mobile
As we all know, the biggest advantage of notebooks is the "mobile", but "mobile" also requires caution. In general, the notebook will appear in the move slight shaking and vibration - this is inevitable. Most people think that notebook is designed for mobile slight shaking and vibration is not much affected. Indeed, this is not so.
In my many years of accumulated work experience, notebook often move will affect their safety. We "due to frequent movement of security risks arising from" as "cold welding." As we all know, the chips are used above board solder, soldered to the motherboard. Notebook when moving, each will produce a slight vibration to weld loose.
Our analysis of the biopsy when microscopy have been used 400 times over, South Bridge and a tin solder on the motherboard ball. Solder ball and the South Bridge connected the upper and lower and the board is connected, in the South Bridge connecting parts of the phenomenon of a slight fault.
Overall, the notebook is best "can not move, not moving," always move would lead to "cold welding", so that the stability of lower notebook.
8, notebook computer performance can not be ignored - temperature
In factories, notebook computer has a performance index can not be ignored, that is "temperature." As we all know, the above board with solder solder chips are up, the temperature difference is large when the solder because of "heat up cold shrink" and appear broken.
Example: notebook computer used in outdoor winter games. When games start, notebook processing load increases, the heat is increased, the machine gets hot. After the shutdown, due to relatively low ambient temperature, forced to board within a very short time by the thermal cooling. As a result, it has greatly affected the stability of solder. More serious, but also a "board deformation," and so on.
Finally, I teach you a check internal temperature of notebook a good way. If the notebook shell temperature reaches 40 degrees (hand does it feel, obviously feeling the heat already), then the notebook will not be lower than the internal temperature of 65 degrees. If the notebook is equipped with discrete graphics in the run for 10 minutes 3DMARK, the graphics card is probably the temperature around 80 degrees - the premise that better thermal performance notebook. If the notebook cooling performance is not good, the situation will be more severe. Dell Latitude D610 Battery general, I suggest we should not lower the temperature in the surrounding environment, taking laptops to play games.
