At present, Network On On how to purchase and use Notebook PC Articles everywhere, and on how Solution Notebook Fault Articles are rare. In view of this, bubble network notebook channel decided to notebook Maintenance industry to a major Secret, help the users knowledge and understanding of notebook computers a failure after to face the industry.
The importance of self-evident for notebook Battery . If there are no batteries, laptop will become desktop PC or one machine.Laptop Batteries Internally by Batteries And protection panels, batteries is responsible for electrical storage the work to protect the board in charge of security . Batteries are consumable items, each with a time can causeCapacityThe attenuation, it will have a direct decision laptop battery is good or bad .
Notebook battery life Shorter, laptop battery can not be used, laptop batteries a sudden power-down (such as : battery sudden from 40 % to 10%), notebook battery charging less power (for example: the battery charge to 30%-40 % Not move ), notebook battery and many left case of a sudden shutdown, these circumstances are likely to be batteries -capacity down or batteries damage caused by . Of course, there may be due to protection board hardware damage, but this possibility is very small.
If you find your notebook more than failure, it is necessary to deal specifically with laptop battery repair operations the company to check out . Below, we give us a presentation to the laptop battery for batteries the whole process .
First, we to use professional equipment detect the problem. detection Battery fault instrument there are many, such as : Texas Instruments product, MAX products, Ateml products, and even some personal home-made products. Our company most commonly used is the Texas Instruments (United StatesTexas ) EV2300.
Once detected a battery failure, should be prepared to laptop Lenovo Thinkpad x61 Battery change batteries of online Circulating a statement – laptop battery fails, you can into the refrigerator or the depth of charge and discharge or pulse current activation method of repair. This is wrong .
If the nickel-metal hydride batteries or nickel-cadmium batteries, does by the depth of charge and discharge the method, the part of the repair ( not fully repaired .) However, we now use laptop computers, equipped with are lithium batteries. Li-ion
Dell Inspiron E1405 Battery failure, are basically because the batteries positive and negative material occurred disintegration . This situation is not reversible, so can not be by the above method repaired . Can only be by Replacement Batteries and decryptedUnlock, for repair.
To laptop battery change batteries, first have to tell you about the laptop Inspiron E1705 Battery structure. Laptop battery can be divided into three parts: the shell, batteries group and protection board. In general, the laptop battery can be divided into three parts: the shell, batteries group and protection board.
- Shell, which is the laptop Dell XPS m1210 battery casing . According to bonding the different ways of can be divided into : snap type, ultrasonic adhesive type and glue -type .
- Batteries group, that is, the batteries by in parallel, a serial fashion together. In accordance with the parallel series combination of the different can be divided into : 2 and 3 strings ( most common), 2 and 4 string, 2 and 2 series, 3 and 3 strings and 3 and 4 strings ( relatively rare ).
Note : 2 and 3 series means, first two batteries in parallel together, then 3 groups like parallel to the together batteries in series. 2 and 3, series a total of 6 batteries, that is, we usually say that the 6-cell lithium Dell Latitude D630 Battery.
- Protection board, which is an based on SMB1.1 agreement board, with power management functions and discharge management.
- Protection board, a piece of based on SMB1.1 circuit board, above 3ChipThey are: the battery meter management chip, charge and discharge management chip, and serial EEPROM memory chips.
Protection of plate the front has a HP 530 battery measurement management chip and charge-discharge management chip. Protection board on the back with a serial EEPROM memory chip, the protection panels Decrypt and unlock are two different things. In short, only be decrypted can into the battery managementSystemOnly the battery management system unlock can change the battery the parameters of and use information. If only changing batteries, do not unlock, you can not achieve satisfactory results (eg : battery only charging to the last recorded full charge capacity, the battery management information shows maintenance used before the number of ) .
We use professional equipment and related software the protection board to decrypt to unlock. Of course, according to battery management chip design manufacturers different, use the appropriate equipment. Use of specialized equipment and related software the protection board to decrypt to unlock, according to Dell Vostro 1720 battery management chip design manufacturers different, use the appropriate equipment. Protection board decryption Unlock software, If the protection board hardware damage, we also use the oscilloscope, multimeter and logic analyzer.
Get protection board, the respect of the handling batteries of the . Now, I ‘ll introduce about batteries sorting, matching and composition. First, we want to use sub- capacity cabinet and internal resistance of meter on the batteries the capacity, internal resistance, voltage, sorting, pick out various parameters compared similar were with groups. Pick out in all aspects parameters are relatively similar of the distribution group. Then, we will use spot welding and nickel films, the batteries together.
With spot welding and the Nickel plate will be batteries grouped together. A nickel plate, there is nickel film. Nickel-plated sheet main material is iron, in fact, in the iron on the thin plating layer of nickel, per unit weight of the cost than the nickel film lower 60 times .
Speaking of nickel plate, a small trick can tell youShareIt. Our company uses the nickel film, all with rounded corners . And the common flat of nickel piece, compared fillet nickel plate with the anti- piercing, etc., can effectively prevent short circuit. On the protection board Decrypt the unlock, on the batteries combination of finished, you can put shell to protect the plate and batteries assembled together.
The shell to protect the plate and batteries assembled with assembly process, the maintenance staff to maintain the most serious working attitude. Laptop Dell Inspiron 1525 Battery pack, it is best to use good insulation material. Please see the above two pictures, the former is imported insulation materials, high temperature, anti- puncture, anti-aging, etc; which is textured paper, insulation is poor, cost than the former lower 2 times .
Sticky shell, the test is no problem to connect to the user. Maintenance after the battery, with the new factory the Dell Inspiron 9300 Battery is similar to the need for the first charge and discharge calibration. We recommend that : first, harge 10 hours (charging process, we can Power Work), charge 10 hours after the call on the finish . Cycle the above steps 2-3 times to achieve the best results .
