What is the situation when the charging on the computer is 0 and the charging shows that it is conne

Problem analysis: It is likely that the battery has not been used for a long time or has been used for too long, resulting in over-discharge, unable to activate and invalid. Try continuing charging while the power is off, and if it still doesn't work, you'll need to replace the battery or use the power source directly.

For rechargeable batteries for laptops and other devices, the process of charging and discharging must be carried out correctly in order to be safe to use and maintain a normal service life.

Solution: 1. If there is a stable AC power supply around, the battery should be removed and the AC power supply should be turned on.

2. If there is no stable AC power supply around, you should turn off the battery and fully charge it first, and then use the battery to turn on the operation until the power consumption reaches the value of the set automatic shutdown (such as 10%-20% of the remaining power), and then turn off the power to continue charging, and the cycle repeats. Some brands of computers, such as Toshiba and Panasonic, come with their own battery safety procedures to protect them from overcharging or over-discharging, so as to extend their service life.

3. If the battery is not used for a long time, the battery should also be fully charged every two or three months and used normally.

If the computer connection adapter can be turned on normally, you can charge it for a while and then disconnect the adapter, if the battery power increases, it means that the battery is overdischarged, and it can be charged in time;

If the battery level is still 0 after charging for a long time, it may be a battery failure and it is recommended to send it for repair.

Causes: 1. Software problems.

Generally speaking, many computer brands such as Dell, Lenovo, Sony, etc., will equip their laptops with power management software, if a certain "battery protection mode" is enabled, the power management software will disable the battery charging and discharging after detecting the user's use of AC power, so as to extend the battery life.

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 no charging option, and if there is no problem with the hardware, the battery will be able to charge.

2. There is a problem with the hardware itself.

Generally speaking, we can use restarting the computer and replugging the battery to judge, if the battery still can't be charged, you might as well install some hardware detection applications to get an approximate reference information about battery loss. If it is determined that the battery hardware is faulty, do not open it by yourself or try to repair it, there is a certain risk, it is recommended to take it for repair.

Refresh the battery by the software method:

We can use some computer optimization software or hardware detection software to do a comprehensive check of the computer, IBM notebook provides a "battery maximiser and power management" software, by running this software, we can have a good solution for the battery capacity display is incorrect and the battery life is reduced.

At the same time, you can get the usage of the laptop battery, as well as the amount of laptop battery loss, which will be displayed in the software. The computer will automatically calibrate and discharge the battery according to the state of the battery, and when the program is over, you can find that the difference between the actual capacity of the battery and the design capacity will be smaller (but still exists).

Here's why:1. Check whether the charging function is disabled.

The laptop has a "no charging" function in the battery option, and the adapter directly supplies power to the laptop without charging the battery, in which case it cannot be charged. It is recommended to check the battery options to see if the charging function of the notebook is disabled, of course the win8 system is slightly different.

2. Check whether the charger is original.

3. If the computer power is in the range of 90 percent and 100%, in order to maintain the battery, the computer will sometimes be connected to the power supply and not charged.

4. Poor contact and battery damage.

5. The charger and battery are loose.

Damage to the charger will also cause the power connection to not be charged, try to change to a charger of the same brand.

If there is no problem with the check settings, then most of the battery internal control circuits or cells of the notebook win7 system have problems, and they need to be rented and repaired.

First of all, check whether the battery charging is disabled in the laptop battery settings, and some battery management software also has a disabling charging function, you can check it. It is also possible that the battery has been left unused for too long, resulting in poor contact, and it is recommended to open the laptop to clean the dust. Unplugging the power cord or battery and plugging it back in can also solve the problem.

Solution: 1. If the laptop battery is in poor contact, it is recommended to shut down and plug the battery, and then turn on the system to check.

2. If the battery is caused by low voltage protection, it is recommended to use a hair dryer to heat the battery for a few minutes before connecting it to the computer for charging.

3. If the motherboard BIOS is abnormal, unplug the power cord, remove the battery, and press and hold the power button for 30 seconds without letting go.

4. The battery is aging and damaged, and the battery can only be replaced. <>

The power supply is connected to 0% of the computer's power, and if it is not charged, it may be a power adapter failure, battery failure, or motherboard failure.

1. The power adapter is faulty.

The power adapter is a computer charger, and you can use a new power adapter to charge the computer to determine whether the charging failure is caused by a damaged power adapter. If the power adapter is damaged, replace it with a new one.

2. Battery failure.

Battery failure manifests itself as not being able to charge, the actual power adapter has a very short battery life, or it is a charging failure. There is a certain limit to the battery life, and it is enough to replace it with a new one.

3. The motherboard is faulty.

If replacing the power adapter or battery does not work, you will need to send your computer to a professional repair shop for repair.

How to maintain your computer battery:

1. Keep away from excessively high temperature environment.

The laptop has undergone high-density processing, and there is no problem of poor rolling in general use, and the high temperature mentioned here mainly refers to some special circumstances. For example, if you throw your laptop in the car in the summer, the temperature in the car can reach more than 50 under the sun, which is very serious damage to the battery and has certain safety risks.

2. Do not overuse the battery.

The computer's operating system and power management software will generally give the first warning when the battery is only 10 -20, and when the battery is too low, you should charge the laptop in time, and be careful not to let the battery run out completely. <>

The computer has 0 power and the power supply has been connected, but it has not been charged because of excessive discharge, battery lock, too low temperature, power management, power management, battery damage, etc.

1. Over-discharged, the battery car is locked.

When the laptop is connected to the power supply, it will show battery 0, the power supply is connected, and after unplugging the power supply, although it will prompt that the power is insufficient, it can be used normally, indicating that the battery power supply is normal, but it does not show charging, and the battery is likely to be locked.

Solution, unplug the laptop connected to the power supply, drain the battery until it shuts down, and then connect the power supply to charge normally.

2. The temperature is too low to charge and cannot be charged.

When the computer is connected to the power supply, it will display battery 0, the power supply has been turned on, and it is charging, and it will shut down immediately after unplugging the power supply, indicating that the battery is out of power. Lithium batteries will not be charged when they are close to zero.

To solve this, put the laptop in the bed for two or three hours, or the hair dryer heats up the battery (blowing for a few minutes is fine).

3. Power management drive.

When the computer is connected to the power supply, it will show that the battery is 0, the power is connected, it may be that there is a problem with the driver if it is not charging or charging, it is recommended to go to the official ** latest ACPI power control driver or enter the PE to see if it is normal.

4. The battery is damaged.

There is no problem with the above inspections, it may be because there is a problem with the internal control circuit of the battery or the cell, then you need to go to the maintenance point to repair, and the battery is generally guaranteed for one year.
