What happens when the power supply is connected and not charged?

Mine is also Lenovo G480, that's because you use the battery maintenance mode, which can only be charged to sixty percent, which is good for the battery, if you want to rush to 100 percent. Let's change the battery mode to full mode. However, if you often use power supply and less battery power, use maintenance mode, so that the battery life is long.

Mine is also Lenovo G480, that's because you use the battery maintenance mode, which can only be charged to sixty percent, which is good for the battery, if you want to rush to 100 percent. Let's change the battery mode to full mode. However, if you often use power supply and less battery power, use maintenance mode, so that the battery life is long.

1. Check the current battery level.

First of all, it depends on the power of the battery at this time, if the power is between 90%-100%, then it may be normal to not charge it. Because in order to protect the life of the battery, the number of charging times will not be so frequent, and it will only be charged when the battery level is less than 90% (95% in many books). Some notebooks can set how much the battery level is lower before charging, which is off topic.

2. Check whether the charger is original.

Sometimes, for example, Dell's 1450 notebook will pop up a prompt box when a prompt "Not Charging" appears, "The type of AC adapter cannot be determined. Your system will run slower and the battery will not charge. Connect a Dell 90W or higher AC adapter for optimal system performance.

At this time, you should first check whether the charger is the original charger to see if the adapter power is correct, if not, it needs to be replaced.

3. How to judge the power of the adapter.

As in the previous step, some notebooks require a 90W power adapter, so how does the notebook judge the power of the adapter? The charger of the notebook is a general "round needle" type adapter, and the needle in the middle plays a power identification function, which is not as high-tech as you think, right? If the needle is broken or the thread is missing, then fix it quickly.

4. Whether the charging function is disabled.

Some notebooks have a "no charging" function in the battery option, and the adapter directly supplies power to the notebook without charging the battery, in which case it cannot be charged. It is advisable to check the battery options to see if the charging function of the notebook is disabled.

5. Updating the BIOS may solve the charging problem.

If you know that the battery and adapter are okay after testing, then update the BIOS. Updating the BIOS may resolve some of the rare issues. Different notebooks have different ways to upgrade the BIOS, for example, HP provides a flasher program under Windows, and the graphical interface rookie can also smoothly get started with the BIOS upgrade.

Some notebooks still use pure DOS as an upgrade program.

The power supply is turned on and not charged, which is probably caused by these reasons.

1. The main reasons for the prompt "The power supply has been connected and not charged" are as follows:

1. The power connection of the notebook is not in good contact.

2. The built-in battery of the notebook is damaged.

3. The power mode is set to the best battery maintenance, and it will not be charged when it reaches 50%.

Second, the way to solve the above problems:

1. Replace the power cord or socket, try several times to see if it can be charged, if the charging is successful, it is the cause of poor power contact.

2. If the built-in battery is damaged, you need to replace a battery with the same model.

3. The power mode is set to "Maximum Battery Life", so that the laptop battery will continue to be charged.

It could be a power outage, a broken power outlet, or the device is fully charged. 1. The power supply has been connected but the power has not been charged The reason for the power outage: This year, many areas will have power rationing, and it may be in a state of power outage when charging, so it will cause the power to be connected, but the state of not charging, it is recommended to check whether the circuit is running normally, whether it is because of the power outage caused by the electricity bill of the Zen Shen Group or other reasons, and then it cannot be charged.

2. The reason for the power socket that has been connected but not charged: In the case of determining that the power supply has been connected, the reason for not charging may be due to the damage of the power socket, and it is recommended to replace a power port. If it is charged for a while and broken for a while, it may be considered that the small motherboard of the device is damaged at this time.

3. The reason why the power supply has been connected but the equipment has not been charged is fully charged: As we all know, most of the current equipment will automatically cut off the power supply when it is fully charged, but it will also show that it is charging. This is designed to prevent damage to the device's battery caused by overcharging.

In the case of full power, it will automatically cut off the power supply, and another advantage is that it will not cause the equipment to be caused by the charging time and too long. <>

The electric morning laugh pool cannot be charged, and the power supply shows that it has been connected and not charged, and the reason and solution:

1. Open Power Manager - Battery - Battery Maintenance.

2. It may be a problem with the system or software settings, generally speaking, many computer brands such as Dell, Lenovo, Sony, etc., will equip their laptops with power management software.

If a "battery protection mode" is enabled, the power management software will prolong battery life by disabling charging and discharging the battery when it detects the user's use of AC power.

So, if you find that your laptop is not charging, you can first go to the relevant power management software, turn off the battery protection mode or check the disable charging option.

3. The problem of the adapter, the failure of the adapter will also lead to the above problems, but it can generally be detected and detected, if the adapter is used for a long time to work, if there is a problem, it will be powered off by itself, which is very easy to detect.
