There is no really practical laptop battery memory chip refresh software.

1. It is not possible to achieve under the operating system. This has nothing to do with the memory of the battery chip.

2. The FCC (full charge capacity value) of the battery has become smaller, if the battery is not used for a long time, you can do 1 full learning (complete charge and discharge, charge and saturation - > discharge - > and then recharge).

3, This is after the battery's gas gage IC will recalculate the fcc value of your battery.

4, but if your battery has been used for a long time, it is time for you to replace the battery, because the life of a battery is almost 2000 cycle counts.

Like you said, this situation is that the battery is memorized, you can see if the battery is leaking, if there is, then 100% need to be replaced, if not, you can try to solve it according to the following methods: wrap the battery in newspaper, and wrap it in a dry and clean food bag and put it in the refrigerator room temperature for 24 hours, then take it out until it becomes normal temperature, then insert it into the notebook, charge it continuously for 12 hours, and carry out a complete charge and discharge, if it can be activated and charged, then congratulations, you don't need to change the battery, If it doesn't work, you can only replace the battery.

No loss, then it is not a problem with your battery, most of the problem is the adapter line, you can change a new adapter, the general adapter for AC power (that is, light for the computer) can be used for a long time, but it is often used to charge the laptop battery on the machine The life span is only about two years, and it cannot be charged into the battery after this life, so often guests report that the battery cannot be charged or the computer does not respond when the battery and the power supply are connected at the same time, in fact, sometimes it is not the battery at all, If you need to charge the battery, it is best to buy a new adapter or buy a direct charge of the battery, the battery should not be used at the same time as the power supply, even if there is power management software, it is also lossy

The second row on the top, the row of icons, the third on the left, the battery icon on the red and the blue on the bottom, click on it, and the screenshot of the displayed information will be pasted up for me to see.

The data you provide is the data recorded by the memory chip inside the battery, and it is not easy to find the special interface and software to modify these data, so it is better to find a professional repair shop for laptop batteries.

Judging from the data, your laptop battery has aged and can only use 1 4 capacity, that is, if it used to be able to use 4 hours, now it can only be used for 1 hour.

Even if the battery cell is replaced with a new one, the memory of the chip cannot be changed. Changing the memory of the chip requires special software, as well as dismantling the chip to write the information in, which cannot be done without special tools and a high level of electronic technology.

If necessary, go to a professional notebook battery repair point to repair it, between 100 and 200 yuan. But if it is a thinkpad's battery, it is not easy to maintain, and the chip data is not easy to change, even if it can be changed, ** is very high.

Repair? What do you mean?

As the battery cell ages, the capacity will deteriorate. This is an inevitable phenomenon.

Take a relative approach:

1) Temporarily restore a certain capacity: put it in the refrigerator at 0 degrees for 24 hours (note that the battery pack is completely sealed with plastic film to prevent moisture.) ）

2) Replace the battery: But the most troublesome thing about replacing the battery cell is: once the battery pack is powered off. The protection board of the battery pack will lock the IC....Professional tools are required to decode.

This battery pack is generally three strings and three parallels, but your total capacity of 4884mAh should be three strings and two parallels.

First of all, look for 6 18650 lithium batteries. Assemble and assemble in a way that is three strings and two in parallel, and the assembly method should be the same as the internal structure of the battery packMerge into the protective plate of your original battery pack, make sure that all external connections are intact, and then remove your original battery cell pack.

Install the new group of three strings and two parallel cells according to the arrangement of the battery shell. This is one way to prevent the protection board from locking up the IC due to a power failure).

Setting 2: As shown in the red box in the figure, remove the two options of "Battery Shortage Alarm and Severe Shortage Alarm", the purpose is to let the program not perform the corresponding operation when the power drops to a few percent, so that the battery power is really discharged, so that the battery itself can correct its minimum power and synchronize with the curve 0%.

Except for the ThinkPad R. that came out before 2012The series can be repaired and activated, but it seems that other batteries can't be repaired. It's still the same as before, IBM is very technical.

After a long time, the battery cells are aging, and it is more than 100 to replace the cells.

Laptop batteries are disposable and cannot be replaced. The battery management chip is to provide battery information, and it cannot be changed.

Notebook charging precautions and battery maintenance are as follows:

1. For lithium-ion batteries, no need to activate, just use directly;

2. Avoid exposure to the sun for laptops and batteries, and the working environment of batteries and laptops is best at 10-30;

3. Do not expose the battery to water or other liquids;

4. Please do not unplug the external power supply during the charging process of the battery until it is fully charged;

5. If the battery has been damaged, or if the battery is found to be leaking or there is a build-up of foreign objects at both ends of the battery, please stop using the battery;

6. If the battery is not used for a long time, its performance may be reduced. It is recommended that the battery be stored separately for no more than 1 month, and ensure that the battery is charged every 1 month or so;

7. Do not completely discharge rechargeable lithium-ion batteries, and do not store these batteries in a discharged state;

8. Do not attempt to disassemble or modify the battery, doing so may cause leakage of the battery** or liquid inside the battery, batteries not specified by Lenovo, and batteries that have been disassembled or modified are not covered by the warranty;

9. Do not throw the battery into the buried garbage, and when disposing of the battery, please follow the local laws or regulations;

10. If the computer is not used for a long time, it is recommended that you unplug the battery and store the battery separately. The battery should be stored at room temperature (-10-35 degrees) and charged to 30% to 50%, it is recommended to charge the battery every 1 month or so to prevent over-discharge.

I just changed the cell, and I don't know how to refresh the chip, and the battery also records the previous information, but when the power drops to 7%, it doesn't drop, and I changed it yesterday, and it can be used for more than three hours. Mine is an ASUS A52DE and I bought a Panasonic 18650 3400mAh cell. However, I heard that it is enough to charge and discharge a few times, and I am still trying.

Hello: It is recommended to contact the local service station to test the battery.

Service station inquiry:

It's too dangerous to change the battery, give up, I studied it for a long time and gave up.

Hello! For convenience, it is recommended that you go to Lenovo's service station to inquire about the diagnosis of the problem, the maintenance is free of charge during the warranty period, the main components are guaranteed for 2 years, the system and software are guaranteed for 1 year, foreign licensed goods need to register for IWS global warranty, and the choice of service station can be queried:

Other questions can also be compared in the two forums, the idea forum.

Hope it helps, thank you.

It's a laptop battery** with the answer you're looking for!
