Before disassembling the laptop battery, it is necessary to accurately and correctly determine whether the symptoms that the user encounters when using the device are signs of a malfunction of this part. How to understand this, whether it is worth doing repairs yourself, how to do it, and will be discussed in the material presented below.
When does a battery need repair?
It is worth noting that there are not so many reasons that can serve as a reason for replacing the laptop battery. Their small list is presented below:
- One of the battery components has reached the end of its life. Although quite often there are situations when the control controller continues to work with a non-functioning “bank”. Then you can simply replace only the defective item. But it is better to change them all so as not to return to the repair several times.
- Most battery cells are dead. This is due to blocking the charging of "cans" due to low voltage. In such a situation, the control controller simply marks the components as defective and shuts them down. You can fix the problem with the charger.
- The control controller itself has failed. Most often, the best solution to this problem is to contact a specialized service center.
Consider the following important paragraph of the instruction on how to disassemble the battery of a Lenovo laptop or any other model.
Why does the battery cell stop working?
There are also quite a few reasons for breakdown:
- Overheating device. For this reason, the fuse tripped, which led to the disconnection of the components necessary for stable operation.
- Some laptop battery parts wear out faster than others. In this regard, the life of the entire battery falls.
- Earlier it was said that quite often the control controller disconnects some of the "cans" due to low voltage. Sometimes you may also encounter a simple mistake, the consequence of which is the controller’s inability to detect certain parts of the battery.
Now it’s worth moving on to one of the most important points: how to disassemble the battery from an Acer laptop (the model is taken as an example). After that, several ways to restore it will be considered.
Procedure for disassembling a laptop battery
If you do not have experience and practice in carrying out these works, then the best option would be to contact a specialist. If you are still prepared for the consequences, then just follow the instructions below.
Attention! Before disassembling a laptop battery, it is necessary to discharge it completely. All further work can be done only after that and with maximum caution!
- First you need to open the battery case. To do this, you can use either a knife or a thin screwdriver.
- It is necessary to separate the part along the connecting seam, which can be quite easily found on the body.
- To open the box, carefully insert the tool into the seam. You need to do this on the back of the contacts. Try to act as carefully as possible, as the plastic on the connecting part is thin enough and can be easily damaged.
- Once you have processed one side, proceed to the opposite. Proceed carefully as before, so as not to damage the contacts and the board.
Attention! Keep in mind that the batteries of some laptop models are not suitable for physical interference at home. And if your part is in this category, then all you get in the end is a damaged case.
- After you finish gluing the box, carefully disconnect one part of the battery from the other.
- Now use a knife to remove the battery cells that will be attached to one of the sides. To do this, you need to make a little effort, since they do not stick tightly.
- Once you free the necessary parts from plastic, you can proceed to the next step of the instructions on how to disassemble the battery from an HP laptop or any other model.
- First you need to cut the film that holds the batteries together.
- After that, carefully disconnect the terminals from each.
- Once the latches are removed, you can remove the board and connection paths. At this point, the battery disassembly process is complete. As a result, you will have ordinary batteries disconnected from the general battery circuit, which can be safely used as independent power sources.
After the instruction on how to disassemble the battery from a laptop has been considered, you can proceed to methods for its recovery.
Calibration Utilities
At the moment, this is the easiest way to increase battery life. In order to perform this operation, you just need to access the Internet and find one of the following programs:
- Battery Eater;
- BatteryCare
- Battery Optimizer
These are the most popular and proven utilities that perform battery analysis and automatically configure the most suitable mode for operation.
Battery Replacement
In this case, you still have to refer to the instructions on how to disassemble the battery from the laptop, since it is necessary to change inoperative cells. This is done as follows:
- determine the power of the batteries that are installed in the laptop battery;
- then, according to the previously presented diagram, open the plastic case and get to the cells with batteries;
- disconnect them and replace with new ones;
- reassemble the battery and calibrate.
Important Tips
After all the basic instructions for disassembling the laptop battery and its restoration have been considered, it is worth bringing a few important tips.
- On some laptop models, the battery needs constant power to keep important data.
- If you change the batteries in the battery of the specified type, just connect a 100 Ohm resistor to remove the old ones and still not cut off the power supply.
- When changing cells must coincide: chemical base, charge, age and ability.
- If during operation of the laptop some anomalies began to occur or a short circuit occurs more often, then most likely copper shunts have formed inside the cells.
