​1.    This will make the all-in-one machine less problematic, replaceable battery is easily replaced by bad businesses.
Not the original battery is more likely to damage the phone. There are many problems that lead to warranty, but also for let the user use the battery to cause harm to his mobile phone while using. Extend the life of your phone.
2.    This design also makes the mobile phone body look more beautiful, can well enhance the machine’s Integrity and feel, giving users a better experience.
3.    Will not restart because of the loose contact of the battery
The mobile phone can replace the battery. When we frequently open the back cover, the process of replacing the battery will lead to the battery.
The metal contacts are oxidized, so when the battery and the body are in poor contact, it is easy to cause the mobile phone Somehow shut down and restarted

Sometimes the computer doesn’t sound when we don’t know what the problem is. Then for many people who don’t understand this knowledge, it may be that the computer is broken and needs to be repaired. In fact, the computer suddenly has no sound and there are other reasons. . Therefore, for the problem, the right medicine.

1.    check the sound card, cable, and speakers and other equipment is connected properly; run antivirus software for antivirus;

2.      Right click on "My Computer" - "Properties" - "Hardware" - "Device Manager". Open the "Sound, Video and Game Controllers" with or without problems. No yellow "?" appears. If so, reinstall the driver for this device to resolve it;
3. When there is a sound but no speaker, turn on the control panel---voice and video equipment---volume, put a check mark before putting the volume icon in the task bar.

4.    When there is no sound and no speaker, open the Control Panel ---- Add and Remove Programs ---- Add or delete Windows components, hit the check mark before "Accessories and Tools", click "Next", and then, shut down Restart, the system will prompt to install new hardware, follow the prompts to install;

5.   uninstall the sound card driver, re-install or upgrade the audio driver;

6.     When the sound card driver is installed, the message “Cannot find the AC chip” appears. It may be a computer poisoning, or an audio card driver was accidentally deleted due to an illegal operation, or it is an internal software conflict. The solution is to reinstall the system and drivers.

7. You can also try to shut down and restart.

The importance of mobile phones no longer needs to be emphasized repeatedly. In a word, mobile phones occupy an important position in our lives, work, and entertainment. However, when people use them daily, many problems still arise. Today, we must say that we are using mobile phones. How do we fix after the black screen and how do we prevent black screens?
When a mobile phone has a black screen, it may be a problem of the mobile phone itself, or it may be artificial. Generally, people who do not have this knowledge or experience may directly get a mobile phone repair shop to repair. Of course, this is a good habit, but I Let's summarize the causes and solutions of the black screen.

1. When the mobile phone is black screen, it may be because of long-term don't care about mobile phones. For example, if you fall, often in high temperature and humid environment, you may be black screen due to loose screen or short circuit. At this time, you may consider sending it to the repair shop.
2. It may also be because there is too much memory in the mobile phone. Generally, if the memory of the mobile phone exceeds 80%, it will flash back and appear black. At this time, the rubbish memory should be cleaned up in time and the software that is not commonly used should be uninstalled. The repair method is to press the home button.
3. The mobile phone download software has a virus problem, so it is necessary to kill the mobile phone in time.
4. If the software of the mobile phone system fails, it is possible to check whether the software is the latest version first. If the problem is not solved by upgrading the mobile phone, it can be solved.
5 is the battery is too long, or the battery is overcharged, resulting in shortened battery life, bad battery and battery connector, leading to a black screen or restart, repair method is to replace the phone or replace the battery.
If there are still many problems that cannot be resolved, it is best to go to a repair shop.

1.   Modern smart phones use lithium polymer batteries, there is no memory effect, so absolutely do not need to charge and discharge each time.
2.   Since the battery has a calculated chip power, a full recharge should be done every month for calibration purposes.
3.   Ensure that the original mobile phone charger is used for charging.
4.   There are also power-saving techniques to turn off the use of Wi-Fi and data traffic when not using the phone.
5.   Avoid using the phone at too high or low temperatures. Try not to let him work at more than 35 degrees. In particular, do not charge in this situation, otherwise it will quickly reduce the battery power. So in the car to avoid the summer stay in the car or the sun. If you are already using your phone and it is starting to burn, turn off and cool it before recharging. It is also recommended that the purpose of full charge/discharge on a monthly basis is to calibrate the control chip on the battery, rather than to expand the battery capacity like a nickel-metal hydride battery.
6.   Don't wait until the battery is low to charge the battery. Use as much charge as possible to extend the battery life.

7.  If the battery is used for more than six months, its capacity will drop quickly. Please do not leave it idle for a long time.

The purchase of laptop batteries directly affects the usage time and battery life of your computer.

When purchasing selected batteries, the following points should be noted:

2

Laptop batteries are consumables, and as usage time increases, there will be a certain loss rate.

Since the batteries are generally made by connecting 3.7V 18650 cells in parallel (to form 10.8V), according to the characteristics of the series, that is, the barrel short board effect - the battery capacity depends on the minimum capacity of the battery. And the battery protection circuit has a limited balance of power. When one of the three series batteries in the series is reduced in capacity or the charging is not completely synchronized, the entire set of battery capacity is directly reduced, that is, the standby period.

3

Therefore, the laptop battery can not be long-term loss of electricity, need to use half of the balance time in full of more than half an hour. Repeat once or twice every three months.

4

To buy a battery, a large-capacity, small-capacity, longer-lasting product is more than just a surface digital multiplier, such as 5200mah/4400mah=1.2 times. In fact, the lifespan for buying a 5200mah is generally 1.5 to 2 times that of a 4400mah battery.

5

There are many batteries on the market. Some factories produce batteries that use unqualified or inferior batteries. Their service life is generally 300 cycles (excellent batteries are more than 1000 times), and they are easily attenuated. The internal resistance increases, causing the battery pack to have an unbalanced capacity and charging. Use accelerated damage. Many of them can only be used for more than ten minutes in a matter of months. The batteries are generally unqualified. (If you buy such a point pool you can use the previous steps to buy a good battery replacement). When buying a battery, remember not to buy a battery that costs less than the price of a good battery.

1. The battery is displayed on the computer, is charging, unplugged, and the notebook can stand for a few minutes and the battery is too low. So that the laptop battery circuit board is normally available, this is a laptop battery replacement and repair prerequisites.
2. The laptop battery is generally one-piece assembly, there is no screw, can not be easily opened, the general use of violent dismantling or splitting and other methods. Use saws as little as possible and it is easy to short circuit. Use a knife to gently swipe along the seal line.
3. Do not cut the circuit board directly after the battery is disconnected. The battery to be bought should be welded first according to the state of dismantling the battery, and then the flying lead (connected with the original circuit board) should be used to ensure that the circuit board does not lose power. Because the power failure will trigger protection self-locking. Then there is no way to change the battery.
4. After the flying line is connected, slowly remove the old battery and reinforce the bold new battery connection. The battery can be easily replaced without losing power.
Precautions:
Laptop batteries are prone to ageing, reasonably using batteries, and not being overloaded for long periods of time, or stored at a loss.
The lead-in line must be used during battery replacement to ensure that the battery circuit board does not lose power. Power failure will lock.
It is best to match the internal resistance of the newly purchased battery. The oldness and the oldness should be the same. This will only last longer.

For serious photographers, every photograph needs to be late.
The post-technology of the digital age is equivalent to the film era flush film. Different washing methods can make the photos from the same film appear to be very different, so the photographers in the film era are flushing the film by themselves.
To ensure that you get the results you want. In the digital age, we used post-production software such as photoshop to replace and expand the film's flushing process. Why can we allow flushing technology without tolerance for late-stage technology?
Some people may say that the photos in the later period are not true. How can colors be so brilliant? Then you knew that all the small cameras set up a photo processing program inside the camera. A photo shoot will immediately adjust the color and add sharpness, sharpness, and finally generate jpg photos. This process is also a kind of later period, and Is it a late period that you can't choose. Do you think the photo taken directly with a small camera is not true?

In fact, taking pictures is very expensive, if your battery can not meet your needs, please click this link.

Is the power in the computer important?

1: very important, of course, depends on your configuration
2: If your configuration is good, you need a good power to drive your CPU and other components, low voltage, unstable power will affect the performance of the computer
3: So, it is recommended to buy a good power supply. If the configuration is low, the requirement can be low, but a good power supply can extend the life of the computer.
4. Very important ~~ Poor power quality, resulting in crashes Hardware running unstable, short circuit, burned, etc.
If the CPU is the human brain, then the power supply should be three meals a day, eat well, then do nothing to work
