The laptop has been used for almost two years, and the battery has been drained by 25, what should I

This is normal, not serious, and the battery can be removed in a place where there is a power supply. Direct use of the power supply.

It's not bad, mine has only 50 left.

This is normal, just plug it into the power supply.

There is no problem, the battery wear is normal, mine has been worn out in two and a half years, and there are some brands of computer batteries that are basically scrapped in two years. In addition, depending on the power management settings, it can be set to the maximum life mode when using a lot of AC power, which is conducive to protecting the battery.

1. The remaining battery time (power) prompted by the system is only an instantaneous reference value, and the actual battery life time is directly related to the operation of your current computer

1. Reduce the brightness of the screen, reduce the use of built-in optical drives and speakers.

2. Turn off idle wireless network cards, Bluetooth devices, etc.

3. Adjust the power consumption mode to "energy saving" and "balanced".

Second, the battery is a consumable product, it is normal to have a certain amount of loss, and after a period of use, the battery life will become shorter and shorter. You can try to correct the battery level by fully charging and discharging the battery, here's how:

1. Unplug the external power supply, turn on the battery only and enter the BIOS.

2. Wait for the battery to run out until it automatically shuts down.

3. Plug in the external power supply, turn on the machine normally, and continue to charge until the power is fully charged to 100%.

3. Regardless of whether the battery is installed in the computer or not, there will be a phenomenon of self-discharge (about 1% a day, slightly different according to different models).

4. If the above three situations are excluded and the laptop battery is still draining quickly, it is recommended that you consider repairing and replacing the battery.

1.It's normal for your battery to wear out. The normal loss value of the new battery is within 5%.

2.This loss value will be updated after each full charge and full discharge, and each update loss actually has a fluctuation of plus or minus 3%, if there is a loss, you can try to repair the battery, that is, a full charge and full discharge process, so that the battery is kept in the best condition (do it once a month in the future).

3.Here's how to cycle the battery: fully charge the battery when it's off; Turn on the computer and let it automatically discharge until it is empty, and it is best not to operate the computer during the period; If it is fully charged, it can be turned on or not. The battery of a computer that has been used for a long time has a high drain. (Image below).

Summary. The solution to the laptop battery drain is as follows: 1. Remove the laptop battery, plug in the external power supply to turn it on, and observe whether the computer screen and power indicator are responsive; 2. The computer screen and power indicator are on, then the computer is fine, the battery is damaged, please replace the battery; 3. The power indicator is on, but the computer screen is not responding, it is a problem with the screen, please send it for repair.

If the power indicator is not on, please check whether the power adapter is broken, if the adapter is not broken, then there is a problem with the power interface of the computer motherboard, please send it for repair.

Friends, I really don't understand, you can be more specific.

The solution to the laptop battery drain is as follows: 1. Remove the laptop battery, plug in the external power supply to open the potato machine, and observe whether the computer screen and power indicator have any response; 2. If the electricity and hand brain screen and power indicator are on, then the computer is fine, the battery is damaged, please replace the battery; 3. The power indicator is on, but the computer screen is not responding, it is a problem with the screen, please send it for repair. If the power indicator is not on, please check whether the power adapter is broken, if the adapter is not broken, then there is a problem with the power interface of the computer motherboard, please send it for repair.

After the above setting is completed, charge and discharge the battery according to the principle of full discharge and two or three times back and forth, and the curve of the offset of the rising pool next to the electric touch can be repaired. Precautions: When charging, be sure to smile and let the battery be full, the best way is to turn off the battery and charge it for a few hours or overnight, and then unplug the power supply and discharge until the computer automatically turns off.

This goes back and forth for at least two cycles.

Normal. It is normal for a year's battery to wear out about 20%, and if it is well maintained, the loss can even be less than 10%.

For some laptop batteries that have been used for a long time, battery loss is inevitable, and the proportion of loss is as high as 30-40%, which directly affects the battery life.

Battery loss refers to the fact that the actual capacity of the battery becomes smaller and lower than the nominal capacity after a long period of use. Battery wear is commonly referred to as the memory effect, but generally refers only to the memory effect of laptops.
