Good and bad laptop batteries are currently jumbly on the market , a lot of inferior products are full of  the market, including many counterfeit original battery, great hidden dangers to consumers. For non-professional consumers, we propose to select from the following aspects notebook battery:

1. Check the package
Should have the brand. Neutral non-branded packaging as quite a mixed bag, easily lead to inferior products or second-hand purchase of refurbished products.
There should be sealed anti-static bag, lined with anti-static sponge, which is to protect the basic configuration of laptop batteries.
Should have the bar code. Barcode is the country unified management product identification standards authority logo.

2. Check the appearance of
There should be no scratches or old flu, or easy to buy second-hand refurbished goods.
Should have clear parameters, performance, application model identification.
Battery cover down joints should not be opened at the scene.

3. Check for proper instructions and after-sales commitment to protect

Formal professional laptop battery grade cylindrical batteries of qualified products, from the date of the factory, they will be guaranteed one-year warranty. If you can not have this commitment, then the use of batteries and other materials may not pass the quality grade batteries but the secondary batteries. At present the market with large numbers of waste in Japan, Korea, and poor battery laptop battery batteries modified, seemingly cheap products are actually profits products, and the normal use of the laptop devastating explosion will be a serious personal injury caused to consumers.

Different models (in particular, different sizes) of the laptop battery, the higher capacity, the  longer working time. aside of volume and weight  factors , of course, the higher capacity the better.
But the same cell type, nominal capacity (for example, 600mAh) are the same, the actual measurement of the initial capacity different: for example one for 660mAh, the other is 605mAh, is the 660mAh one is better than 605mAh one?

Actual capacity may be high because the electrode materials to increase the initial capacity of more things, and less stable with the electrode things, the result is reused dozens of times after the rapid capacity of high capacity battery failure, the capacity Low battery is still strong. Many domestic batteries manufacturers often use this method to obtain high-capacity battery. The standby time users after six months it is worse than nothing. Civil those AA Ni-MH battery (that is, on the 5th battery), the general is 1400mAh, it also has standard high capacity (1600mAh), reason is the same.

★ improve the capacity cost is the expense of cycle life, battery materials, manufacturers are not modified up and down the article, is not really “improve” the battery capacity.

3, can not boot

If you encounter notebooks get up and can not self-test, power indicator light of the 3 to 4 seconds out of the situation can change according to the following indicator to determine what’s wrong machine.,

A. The top of the keyboard, next to the power button, there are three small lock lights, which is representative of fault diagnosis bright lights .1; (1) represents the flashes; 0 for does not shine

1. If the display flicker 0-1-0, memory problems

2. If the display flashes of 1-0-1, good memory, do not insert

3. If the display flicker 1-1-1 four seconds, and then at the same time off, motherboards and cpu problem

4. If, stable 0-0-1 code, motherboard and cpu problem
5. 0-1-0 if, stable code, motherboard problems
6. 0-1-1 if, stable code, and memory problems.
B. Remove all the peripherals that could interfere with: external power supply, battery, dock, minipci wireless network card, modem, optical drive, hard disk, memory.

C. without any power (remove power and battery), hold down the power button 15-20 seconds, the system will reset the motherboard, which is the so-called discharge.

D. definite displacement of memory, the then external power supply, and then observe the changes in diagnostic lights.

For the d series machines, you can also take the dell diagnostic procedures, hold down the fn is not fixed, and then boot that, if the following error codes, but also on behalf of what the hardware is having problems.

If you remove the memory, there was no 0-1-1 static memory error code, Kanxia table instructions:
1. If only the power lights, motherboard problems
2. 0-0-1 shows an error code blinking, motherboard problems
3. If all the lights four seconds and then locked out at the same time, motherboards and cpu problem
4. Display a static 0-0-1 error code, cpu problem.

4, battery failure

We found that the battery can not charge, and charging indicator light, flashing red lights three times, look at the green light flash, which is that the Apple Powerbook G3 battery broken?
We can be judged through the following steps.
1. Connect the power adapter, boot, press F2 key to enter the BIOS settings, press Alt + P to “Page 5 of 7″, the following diagram to see the red box as specified in “AC Adapter” is not displayed as “None” or “UnKown”, if it is, then the motherboard or an external power supply problems at this time if the conditions can be exchanged an adapter test.

For the new machine (D610, D410, D510 and other machinery, bios Dell xps m1730 battery  state is the battery info on the following diagram

If the BIOS were “AC Adapter” is not displayed as “None” or “UnKown”, but the number of its power, such as 65W and so on, then the general board and there will be no external power supply failure, please check if the battery problem, Remove the Dell Inspiron E1505 battery, according to their indicator button, to see whether the Asus U3 battery indicator button is displayed as “1,3,5″ state, that is, every other one lights. If so, then the battery is faulty. If all the lights are not bright, then you put the battery and power adapter plug into the notebook above, and then press the button on its lights to see if there are no bright light at this time.

If the conditions, take someone else’s battery and power adapter give it a try, and in another test laptop above your battery and power adapter. If you can determine the problem batteries or power adapter, you can mail the details of repair  test results to the Client support center, and provide batteries or power adapter corresponding number, these two components can be numbered in their respective parts the back of the found, similar to the XX-XXXXX-XXXXX-XXX-XXXX such characters.

Static electricity generation and trigger is a natural phenomenon, we can not be completely eliminated, but as long as usually more careful, it can be avoided. To deal with static electricity, we can take the “anti” and “release” hands. “Defense”, we should try to use cotton clothing and home accessories products, as the fabric, try to avoid the use of chemical fiber carpets and a plastic as the surface material of the furniture, in order to prevent friction electrification. “Release” is to increase the humidity, so that localized electrostatic easy to release. When you use a computer before, you should immediately wash their hands face, on the one hand to maintain a healthy, while also allows the electrostatic charge on the surface of the skin to release the water out. In the winter, we should try to use a high moisturizing cosmetics. Common humidifier. Some people like the indoor rearing ornamental fish and daffodils are also regulating indoor humidity a good way. The daily use of desktop computers and laptops, there are a few tips to note:

A notebook to make use of an external power supply

We know that the laptop will have in the course of currents, these currents can not be released if there is no conductor contact, if the encounter with the static electricity produced by the body, it will generate electrostatic discharge, resulting in blue screen, crashes. In view of this situation, it is recommended to use an external power supply, laptop power adapter three phase plug at the same time maintain a good grounding. Not only can effectively prevent the leakage, but also can prevent the accumulation of static electricity.

2, access to computers before discharge

Due to environmental dry friction, the body has accumulated a large number of charge, often in contact with notebook notebook damage caused instantaneous discharge occurred. Therefore uncertain whether the electrostatic accumulation of the body, first after the release of the body static electricity using a laptop. With the books before, it is best to wash your hands, water well to eliminate static electricity, especially in motion a long time (sports events to make clothes and friction, resulting in a large number of static electricity), after; if too lazy to wash your hands, then take a look around there is no ground metal objects can also have contact with both hands effectively eliminate static electricity. Also to be noted that as far as possible not to touch the books by hand directly connected with the internal circuit elements, particularly the interface, in the next, when particular attention to USB.

3, on a regular basis to the computer clean, efficient addition to static electricity

On a regular basis to the computer to do thorough cleaning, you can effectively reduce the accumulation of dust, while you can use anti-static cleaning materials for cleaning, to help reduce the accumulation of static electricity. Baxter clean your computer cleaning of the three detergents, all contain anti-static formula, can effectively play a protective effect, reducing static electricity, to protect the computer role.

How to deal with static electricity after a fault occurs

Notebook for everyday use, the most common are contact discharge, leading to a normal laptop can not boot. If this situation occurs, you can remove the battery after the elimination of its own static, unplug laptop power adapter, notebook and put it aside for half an hour’s time. Again after a separate access to the power adapter, generally can be a normal boot. If you still can not boot, or the repeated occurrence of the phenomenon of static electricity caused not boot and should be sent to notebook manufacturers to conduct a comprehensive inspection office, if necessary, some parts may need to be replaced.
