How to wire the laptop battery to charge! 50

1. After flashing, due to the change of most of the content of the system, there is a situation similar to the inability to read SD. It can be reverted to the official system to solve the problem. http://63351335

2. You can try to restore the Huawei phone to factory settings first, if not, please enter the Huawei ROM ** area, find the original ROM, and refer to the relevant tutorial to flash the SD card normally.

The second type: the SD card of the Huawei phone cannot be read due to its own damage.

1. Use the following methods to identify whether the SD card has been damaged, 2. Confirm whether the SD card has been inserted correctly, and confirm whether the mobile phone is compatible with the SD card, generally supporting a maximum of 32GB MicroSD card. You can tell if your microSD card is damaged by connecting it to your computer with a card reader or inserting it into another phone.

If you can't read the SD card directly with the card reader, but can read other SD cards, it means that the card is broken, and you don't need to look for the reason on the phone.

Method 1: Through iCloud, transfer the ** from the Apple computer to iCloud and sync it from the iPhone:

2. In the pop-up iphoto page, there is a column on the left side of the vertical column, there is a file called "Shared", and there is an iCloud below, click on it;

4. Drag the ** that needs to be put into iCloud to the album "My**Stream", and then ** will start uploading to iCloud;

5. Then you also have these in iCloud on your iPhone**, just sync them to your phone. (Cloud upload** requires a few seconds or even a few minutes of data transfer at a certain network speed).

Put it back into the computer and rush, you can't charge it if you take the battery out, because the battery of the notebook is professionally designed, and the program inside has a protective effect on the battery.

1. On the first charge, you should charge the battery continuously for 12 hours, and cycle the full charge and discharge 3 times to fully wake up the new battery.

2. If you use the external power supply for a long time, it is best to remove the battery. Many friends don't notice this problem, not removing the battery when using an external power supply not only affects the battery life, but also makes the heat dissipation burden of the laptop heavier, shortening the life of the laptop.

3. Charge and discharge regularly。Even if lithium-ion batteries without memory effects have a certain inert effect, they will be inactive if they are not used for a long time and need to be reactivated. Therefore, if you do not use the computer for a long time (3 weeks or more) or find that the battery charge and discharge time becomes shorter, you should make the battery fully discharged and then recharge, generally at least once a month.

4. It is best to turn off the laptop when charging, so that the battery can be fully chargedDo not unplug in the middle of charging. Charging off will shorten the charging time by more than 30% compared with charging on power, and can extend the life of the battery. It is best to use it 30 minutes after charging.

5. Prevent exposure to the sun, prevent moisture, prevent chemical liquid erosion, and avoid short circuit between battery contacts and metal objects. The number of charging and discharging of lithium batteries generally does not exceed 800 times, and each time it is charged, it shortens the life of one time.

Precautions related to computer charging

1. Use the original charger to charge the laptop.

2. When the laptop is charging, don't touch it with wet hands.

3. Don't deliberately charge the laptop after it runs out, this is not good for the battery, and the computer can be charged when the battery is about 8.

4. Don't overcharge the laptop battery, and then recharge it when you have time.

Purpose:1The connecting wires at both ends of the battery are the lines that provide power to the laptop, and they are also the wires used for battery voltage detection;

2.The connecting wire in the middle of the battery is mainly used to detect the voltage of each group of batteries, which can balance the voltage of each group of batteries and protect the battery from being overcharged or overdischarged;

3.There is also a temperature sensor in the middle of the battery, which can protect the temperature of the battery from not exceeding the rated temperature, and also adjust the charging voltage of the battery at different temperatures;

4.Laptop batteries can only be charged on the same computer, and the manufacturer does not produce a noisy backup for charging laptop batteries, because the computer will test the parameters of the battery in time when charging.

The laptop cannot charge the battery directly through the laptop.

<>How to properly charge your laptop battery

Try to avoid waiting for the battery to run out of power before charging, as this can put a lot of stress on the battery and cause damage. It is more feasible to charge when there is about 20-30% of the battery remaining. In fact, there is a limit to the number of times a notebook's lithium battery can be "recharged", and recharging it all will only greatly shorten the battery life.

At the same time, the battery should be charged in a relatively dry place, and it is also necessary to pay attention to the heat problem, which is the enemy of the battery.

Tips: The use of mobile phone batteries is not the same as the use of laptop batteries, and many people may judge based on their own experience in using mobile phone batteries, and feel that laptop batteries should be used up and recharged, which is not right.

How to store laptop batteries that are not in use for a long time

Should laptop batteries be stored with photoelectric or should they be stored fully charged? Long-term storage of discharge photoelectric will make the battery cell inactive, and even lead to the control circuit protection self-locking and can no longer be used, long-term storage of full charge will bring safety hazards, the most ideal storage method is to use the power to about 40% and then store it in a cool and dry place'Place, about 20 degrees Celsius is the ideal storage temperature. Of course, it is best to take out the battery once a month to use it, which can not only ensure the good preservation state of the battery, but also prevent the battery from being completely lost and damaged.

A few measures to extend the working time of your laptop battery

1> Lower the brightness of the screen: You can use the fn down and up key combination to quickly adjust the brightness (the specific fn + which key needs to look at the respective notebook).

2> Make good use of standby, sleep and other functions: When the computer is not used for a long time, the laptop can be used to standby or sleep, which not only saves power but also prolongs the service life of the computer.

3> Turn on the CPU SpeedStep function, which can greatly extend the working time of the battery: The CPU's SpeedStep function is started by default in the BIOS, and when the battery is used, the CPU will be automatically downclocked to achieve the purpose of energy saving. If it is not enabled, you can press F2 to enter the BIOS to find Performance and set SpeedStep Enable to Enabled.

4> When using the battery, try to turn off the wireless, Bluetooth and infrared ports. At the same time, remove unused peripherals and avoid enabling large 3D programs, games, etc., to reduce unnecessary battery consumption.

1. When charging the laptop for the first time, you must remember to charge and discharge the laptop battery three times, that is, when you use the laptop for the first time, you must fully charge the computer battery three times, and then discharge it, and after completing the electrical work, start using the laptop.

2. In order to better activate the chemicals inside the laptop battery, in the process of using the laptop, it is best to carry out a complete discharge work once a month, so that the chemicals inside the battery can be better activated, so that when we use the computer, the state of the battery can be guaranteed to be the best, and this can also better stimulate the activation performance of the laptop battery, which can increase the service life of the laptop to a certain extent.

3. If the laptop's battery has been left for a long time, we still need to treat it like a new battery, and we need to reactivate the laptop battery.

4. If the battery of the laptop is a nickel-metal hydride battery, it needs to be reasonably controlled for its charging time, and it cannot be charged frequently, otherwise it will reduce the service life of the laptop battery. When using a laptop, it is necessary to charge and discharge it once a month, and charge and discharge the battery, which is beneficial to the battery of the laptop.

5. Lithium electronic battery has a great inert effect, if the laptop battery is not used for a long time, its activity will slowly disappear, so every time it is used, it needs to be reactivated, and the laptop is in an alternating current environment, try to remove the battery, so that the laptop will not be in a charging state for a long time.

6. In the process of charging the laptop battery, try not to use the laptop, and do not unplug the power supply during the charging process, after completing the charging, wait for 30 minutes before starting to use the laptop.
