Laptop batteries, especially lithium batteries, have been idle for too long or have just been repaired, and their charging and discharging curves will deviate to a certain extent. It needs to be corrected and repaired by several full and complete cycle steps. The curve is also called the battery's self-learning process. Common laptop battery loss repair methods mainly include the following methods.

Laptop battery repair method 1

Setup (This is the most important step related to repairing the laptop battery to its best condition. Please Don’t pay unnecessary attention)

a Open My Computer--Control Panel--Power Options--Power Usage Plan,

Select all the time parameters of the battery use item to From No

b Uncheck the two options of the alarm item. The purpose is to prevent the program from responding to the corresponding operations when the battery drops to a few percent, so that the notebook battery can truly be discharged. Let the battery itself correct its minimum capacity in sync with the 0% curve.

Charging and discharging:

After setting the above, charge and discharge the battery according to the principle of full discharge and discharge. Go back and forth two or three times to fully discharge the battery. Repair the shifted curve.

Note: The battery must be fully charged when charging. The best way is to turn off the battery and charge it for a few hours or overnight, then unplug the power supply and discharge it until the computer automatically shuts down. . Do this for at least two cycles

Laptop battery repair method two

The instability of the battery during use and charging will cause the battery capacity to decrease, but This decline is not due to aging, so proper calibration can restore this lost capacity. Therefore, it is very necessary to perform battery calibration regularly, such as once every 1-2 months.

Laptop computers like Compaq and IBM provide battery calibration functions in the BIOS or power management program, so friends who use these two brands can just follow the prompts. For those users of brands that do not provide this feature, you can follow my steps below: Set the screen saver to "None", set the power scheme to "Always on" in Windows Power Management, and turn off all the device-related menus below. set upSet to "Never". In the Alerts tab, set the "Low Battery Alarm" to 10% and the Action to "Do No Action"; set the "Critical Battery Shortage Alert" to 3% and the Action to "Standby". Adjust the screen brightness to the highest level, confirm that all windows have been closed, and save all previous work data. After confirming that the battery charge is above 80%, unplug the power and all external devices. If the screen brightness automatically decreases at this time, please turn it on. to the brightest. OK, you can go to bed. After the discharge is completed, the notebook will automatically shut down. Then plug in the power and let the notebook charge. Be sure to wait until it is fully charged before turning it on, and then restore the power scheme to the settings before calibration.

With a calibrated battery, you can use it with confidence.

Laptop battery repair method three

Use the battery refresh program to restore the battery’s discharge time: Most brand laptops have battery refresh programs, use It can repair the battery. There is a software called "BatteryMon", which has many versions. It is a small software specially designed for laptop battery monitoring. It can display the discharge curve and will run automatically after installation.

Laptop computers are equipped with batteries that due to improper charging and discharging at ordinary times lead to shorter and shorter battery discharge times, leaving only less than 5 minutes. It is very inconvenient to carry a laptop computer out for work. Is there any way to restore the battery's discharge time?

Battery Repair In view of the above situation, battery repair can use the battery refresh program launched by IBM to refresh the battery to restore the discharge time. The specific method is as follows .

(1) Use AC power to power the laptop and download the refresh program for the laptop battery provided.

(2) Restart the computer, press the F8 key to enter the boot menu, and select safe DOS mode.

(3) Enter the directory where the file you just downloaded is located, execute the battery refresh program isbr0lww,exe, read the warning message, insert the floppy disk as required, and then press the Enter key to perform the self-extracting operation.

(4) Use this floppy disk to boot the computer, and the startingpc-dos... prompt message will appear on the screen.

(5) Unplug the AC power supply as prompted, and the program will automatically discharge the ni-mh battery. After the discharge is completed, the system will automatically shut down.

(6) Since the battery temperature is high at this time, you should not turn it on immediately. Let it cool down for a while before plugging in the AC power supply.

(7) Boot the computer with a floppy disk, this time autoexec.bat file will automatically run the refresh program and ask the user whether to proceed. After selecting yes, press the Enter key.

(8) At this point, the program begins to refresh the battery, and the process is very fast. When you return to the dos prompt a:>, it means that the refresh has been completed.

　(9) Turn off the computer and charge the battery until the indicator light turns green.

(10) Repeat the above process 3 times to get the best results.

Laptop battery repair method four:

Refrigerator freezing method 1: Wrap the battery in newspaper and then put it in a plastic bag and put it in the freezer for three days (newspaper can absorb excess water) 2) After three days, take it out to room temperature Put it down for two days 3) After two days, charge the battery. After it is fully charged, install it into a mobile phone package and test it (it is estimated that 80%-90% can be saved)

This method was revealed by an engineer from a well-known battery manufacturer. According to the test Friends pointed out that the effect is quite effective.

As for whether it has any effect, the battery is running out anyway, and everyone has a refrigerator, so friends may wish to give it a try
