Apple computer won't charge

Why can’t the Apple computer be charged?

The temperature of the computer is too high or too low, and the battery activates the protection system and cannot be charged: because of the lithium battery The optimal charging temperature is 0℃-45℃. When the overall computer temperature is lower than 15℃, the charging system will automatically slow down the charging speed. When the temperature is lower than 5℃, normal charging will not be possible.

The temperature may be too high or too low. Apple batteries have a protection system that protects the battery from overheating or low temperature. The charging temperature range of lithium batteries is: 0℃ to 45℃. Charging is slowed down below 15°C. It will no longer charge when it is below 5℃. Because low-temperature charging will damage the battery, high-temperature charging will cause the risk of heat generation.

It is possible that the charger is not the original charger and the computer cannot be charged. Check whether the charger is the original charger. If it is not the original charger, you can replace the charger with the original charger at this time. It is possible that the power adapter of the power supply is not powerful enough, so it cannot be charged.

Enter the system and see if the battery can be charged normally. Battery failure, or system problem. The reason why the Apple computer's charging indicator light does not light up and cannot be charged: the charger is damaged. The plugboard and socket are damaged. If the computer charging port is damaged, it indirectly means that the motherboard is damaged. Power outage or trip. The USB interface is loose.

Take Apple MacBook Air and win10 system as an example. The main reasons for normal charging are: the charging environment is too cold or too hot. Apple computer batteries have a protection system. When the charging temperature of the lithium battery device is lower or higher than When the temperature is 0℃-45℃, the battery will automatically turn on overheating or low temperature protection.

After the temperature rises a little, then observe whether it can be charged normally. Generally, this problem is prone to occur outdoors in the north. If it still doesn't work, it is recommended to borrow a power adapter from a friend to try. The most likely reason is that the charger is broken. If it is out of warranty, it is better to buy a non-original one to repair it.

What should I do if my Apple notebook cannot be charged?

1. If you encounter a problem that cannot be charged, don’t worry. Plug in and out the charger a few times and restart the host to avoid poor contact. Case. If the above method is invalid, check the color of the charger indicator light. If it is green, it is recommended to turn on the air conditioner if it is winter.

2. However, sometimes users will encounter some problems, such as Apple laptops not being able to charge. First, the user can check whether the power adapter is damaged. If it is damaged, it can be replaced with a new one. If there is no problem with the power adapter, you can check whether the battery is damaged. If it is damaged, you can replace it with a new one.

3. You can also try to reset NVRAMPRAM: press option command P R at the same time immediately after turning on the computer. After hearing 3-4 power-on sounds, let go and enter the system to see if the battery can be charged normally. Battery failure, or system problem. The reason why the Apple computer's charging indicator light does not light up and cannot be charged: the charger is damaged.

4. It is recommended to replace the power adapter. Battery failure: The battery life is short and will lose capacity after long-term use, causing the battery to be unable to charge. If the battery life is short, consider replacing the battery.

5. When encountering this situation, please place the computer at a suitable room temperature for charging according to the actual situation. Power adapter failure: Sometimes there is a problem with the connection cable in the power adapter, which may cause the computer to be unable to charge properly.

6. The charging environment is too cold or too hot. The battery of Apple computers has a protection system. When the charging temperature of the lithium battery device is lower than or higher than 0℃-45℃, the battery will automatically turn on the overheating or overheating function. Low protection. Especially when the temperature is below 15℃, charging will slow down and when below 5℃, charging will stop.

Details of why the Apple computer cannot be charged

3. Replace the charger: It is possible that the charger is not the original charger and the computer cannot be charged. Check whether the charger is the original charger. If it is not the original charger, you can replace the charger with the original charger at this time. device.

4. Why the Apple computer cannot be charged: It may be caused by your charging environment being too cold or too hot. There is also a problem with your adapter. Check to see if the indicator light is on. Finally, there is a problem with your system, which will automatically prohibit charging.

5. First check whether the power supply has power and whether the circuit is normal. Check whether the power indicator light on the charging cable shows the charging status and whether there is a charging mark on the computer. If not, it may be a problem with the wiring or adapter. Try another one. Do not operate the computer in an environment with temperatures that are too high or too low.

The mac is connected to the power supply but cannot be charged.

The temperature may be too high or too low. Apple batteries have a protection system, which protects the battery from overheating or low temperature. The charging temperature range of lithium batteries is: 0℃-45℃. Charging is slowed down when the temperature is below 15°C; charging is stopped when the temperature is below 5°C. Because low-temperature charging will damage the battery, high-temperature charging will cause the risk of heat generation.

The reason why the MAC is connected to the power but cannot be charged is because the power management setting is wrong. Power management settings may also prevent charging. MAC computers have highly customizable power management functions that users can adjust according to their own needs. However, if the power management settings are not configured properly, it may prevent proper charging.

Most of the reasons for this situation are due to the aging of the laptop battery or lack of daily maintenance. The power is connected but not charged. Solution: The battery has been left unused for too long, resulting in poor contact. It is recommended. Opening the laptop, cleaning it, and unplugging and plugging in the power cord and battery may also solve the problem.

If there is no problem after checking the settings, then most of the time there is a problem with the internal control circuit or battery cell of the battery of the laptop win7 system, and it needs to be taken for maintenance.

It is possible that the charger is not the original charger and the computer cannot be charged. Check whether the charger is the original charger. If it is not the original charger, you can replace the charger with the original charger at this time. It is possible that the power adapter of the power supply is not powerful enough, so it cannot be charged.

It may be that the computer displays an error. Usually, this situation can be solved by restarting the computer or plugging and unplugging the power supply again. Apple computers have their own protection mechanisms. If this phenomenon is caused by triggering its own protection mechanism, you need to go to an Apple store for testing.
