It happens that your PC in the lower right corner of the monitor began to show an alarming red cross. The system indicates that it is recommended to replace the battery on the laptop. What to do in this case? Is there a solution to the problem? Of course have. But it is worth noting that this system message is not always correct, and it does not need to be blindly trusted. Perhaps the problem lies elsewhere.
Reasons for the problem
Fortunately, there are not many of them at all. The most logical version of the error is the natural deterioration of the battery and its incorrect operation as a result of a long operating time. The operating system itself analyzes the battery and indicates that it needs to be changed.
Wear is a certain number of discharge / charge cycles during which the battery loses its functionality. By the way, this period is indicated in the instruction manual, and surprisingly, on average it is 2-3 years. Although, of course, it all depends on the correct use. Perhaps the laptop battery, which worked for 6-7 years, will work like a clock.
Another reason is a system failure. It happens that the system takes the working battery for a faulty one, and therefore a similar error occurs. There is another factor due to which it is recommended to replace the battery on the laptop - this is a problem with the outlet. This happens due to power surges or malfunction of the outlet. How to solve this problem, you guess yourself, but as the previous two, consider in more detail.
Simple actions
Before delving into system changes and other difficulties, try to get started:
- Carry out several charge and discharge cycles. In this case, the battery needs to be charged only when the laptop is turned off.
- Also try to remove the battery and leave it alone for 10-15 minutes. Then insert and turn on the laptop.
- Accept and use the laptop as a desktop PC. In this case, no cost.
- Buy a new battery. There may be problems finding the right model.
- You can take the battery for repair. This option is not the best, because not always financial costs can justify themselves.
Update driver
So, we examined why the laptop writes: “It is recommended to replace the battery”, and now we will analyze in detail how to fix it. The first one is updating the drivers. This option is best used if you are sure that the battery really works. With the combination of Win + R, open the command line, enter control. Select "View" and "Large Icons". In the device manager, select "Batteries". From the proposed list, select “Battery with ACPI-compatible management” and delete this item with the right mouse button. Now, for the changes to take effect, we reboot the PC. After turning on, you will not see the message “it is recommended to replace the battery” on the laptop. What if it doesn’t help?
Calibrate the battery
To implement this process, you need to figure out what it is? If you do not delve into the mass of complexities and terms, let us move on to the concept of “memory effect”. In simple terms, this is a decrease in initial capacity. This happens either due to physical defects, or as a result of constant recharging of a partially discharged battery. Simply put, if your laptop is not fully discharged, you charge it, but again - not completely, it loses energy, but in the end does not get it.
The battery becomes weaker due to the fact that the battery seemed to “remember” that border to which it could not charge, and perceives it as the boundary of its capacity. Then a lot of errors appear, and the battery does not work correctly. The calibration process does not make the volume larger; it only deletes all errors from the memory and resumes the capacity boundary.
There are two types of batteries:
Each of them has its own calibration process. In the first case, the “memory effect" practically does not affect the battery. But wear and tear, as with any equipment, necessarily occurs. Therefore, calibration in this case is carried out so that unexpected shutdowns do not occur at a 30% charge. If you still recommend replacing the battery on your laptop, what should you do with a nickel battery?
They require periodic calibration. So, you need to work offline until it is completely turned off. Then charge the battery to maximum. The process itself is preferably repeated a couple of times. But before such a calibration, you need to set up a power plan. We find in the control panel the tab "Power". You will be presented with several battery plans. On different laptops they are called differently. You need to choose “Portable” or “Balanced”. Next, click "Set the power mode" and in the lines "Turn off the display" and "Sleep mode", set the parameter to "Never."
Battery disconnect
This method will not completely solve your problem if the laptop says: "It is recommended to replace the battery." What to do in this case? We do the same thing as in the case of updating the drivers, only instead of "Delete" we select "Disable". In this case, you will simply lose this annoying message.
How to check?
If the system writes: “It is recommended to replace the battery on the laptop”, then first you need to check the battery after all. “Start” - “Run”, in the command line we write powercfgenergy. A check will be made, and the report can be found in the line "Additional Information" - "Battery Information". The higher the value of “Last full charge” relative to the “Estimated capacity”, the better.
How to replace?
Replacing an old battery is very easy. Turn off the laptop. There are two sliders on the back cover. One of them, when you push it back, returns to the place, the other remains in the right position. Therefore, when we snapped off the second one, the first one must be held and the battery removed. To insert a new one, just click it.
Windows 7 is to blame
What does it mean - is it recommended to replace the battery on a laptop? Basically, you have already dealt with this issue. But sometimes it happens that the whole problem is in Windows 7. It turns out that this operating system is guilty of this problem. Despite the fact that Microsoft is trying to fix everything, OS users periodically complain about battery problems.
As users respond, after buying a laptop with Windows7 already installed, after 2-3 weeks the charge time and battery life are almost halved. So far, it is known that it is recommended to replace the battery on a laptop due to inconsistency of certain elements in the system and some BIOS elements, since in this case the battery requires constant charging and wears out very quickly.
If you are faced with the fact that you are advised to replace the battery on the laptop, you already know what to do with it. If all the above methods did not help you, you will have to contact the professionals in the service center. Especially if the laptop is new and is still under warranty. Then the repair will cost you free of charge.
