1. How to repair laptop battery?

We can use the battery refresh program launched by Thor Notebook to refresh the battery and restore it to the discharge time. The specific method is as follows.

(1) Use AC power to power the laptop

(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 on the phone immediately. Let the battery cool down for a while before plugging in the AC power supply.

(7) Boot the computer with a floppy disk. This time the 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 time, the refresh 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 is 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.

In addition, many lithium battery failures are caused by the failure of a certain cell in the battery pack, and this phenomenon is unavoidable. Because the cell properties of each battery cannot be exactly the same, some of poorer quality will begin to age after being used for a long time, destroying the overall (after series connection) discharge curve. Readers who are interested and capable can try to open the battery pack, and with the help of a multimeter, they can quickly find the damaged battery cell (abnormal voltage). If conditions permit, just replace the qualified product according to the corresponding parameters of the battery core.

　1. Settings (this is the most important step related to restoring the laptop battery to its best condition, please do not pay unnecessary attention).

　1) Open My Computer--Control Panel--Power Options--Power Plan, and select all the time parameters for battery use as Never

　2) Uncheck the two options of the "Alarm" item , the purpose is to prevent the program from responding to corresponding operations when the battery drops to a few percent, so that the notebook battery is truly discharged, so that the battery itself can correct its minimum battery level in sync with the 0% curve.

　2. Charge and discharge.

After setting up as above, charge and discharge the battery according to the principle of full discharge and full discharge. Go back and forth two or three times to repair the offset curve of the battery.

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

When replacing the battery, please pay attention to the polarity and make sure the battery is installed correctly.

Method 2: Use dominoes to repair the battery

If you don’t want to replace the battery, you can try to use dominoes to repair the battery. Dominos can be used as conductive materials to repair batteries. You can cut the domino into small pieces and use pliers to sandwich it between the positive and negative terminals of the battery.

Method 3: Use silicone to repair the battery

If you don’t have dominoes, you can try to use silicone to repair the battery. Silicone can also be used as a conductive material to repair batteries. You can apply silicone gel between the positive and negative terminals of the battery and let it dry.
