Laptops are not cheap at all and acquiring one is an important investment with its consequent wear and tear on your pocket. It is also true that, at present, the computer is an indispensable part of our daily lives, almost as fundamental as the mobile phone, the computer is a basic tool for work and studies, although also, in many cases, for leisure. A well-cared PC can last us many years, but sometimes it happens that Doesn't charge laptop battery. This is a real disaster! Is the end of the useful life of our PC approaching? You'll be praying it isn't. And then we are going to explain why this happens and how to fix it.
It is very annoying to have a laptop and walk all day with the need to find a plug nearby because the battery doesn't hold anything. burden? whatWhy doesn't my pc battery charge??
The explanations are several: from there being a cable in poor condition, to the transformer or the battery itself failing. It can even be due to a software issue as well. Let's see all the possible reasons one by one.
Hardware failures due to which the laptop battery does not charge
Sometimes the wires are broken, loose or not connected well, while other times the failure is something more complex and there is a problem with some piece of the laptop's hardware structure that prevents the battery from charging. Let us begin.
Have you checked the cables yet?
It is the most frequent and simplest cause to solve, when the problem is in the cables. It may be that a cable has been chipped, burned by accident, that you have stepped on it with the leg of the table or chair or with your own foot repeatedly and some damage has been caused. This type of accident is also common when we have pets at home, as some domestic animals enjoy playing with cables.
For all these reasons, it is appropriate check the cables before getting more nervous than necessary if we notice that our laptop battery didn't charge enough.
Perhaps, in the best of cases, the cable just came off. In such a case, insert it well and you are done.
It can also happen that the cable makes a bad contact. A failure may occur for this reason, taking into account that the cable that goes from the external power supply to the socket, if it does not make good contact, the battery will not charge.
Other times, the fault is not in the cable itself, but in the power supply that, for various reasons, sometimes unknown, also it breaks down. There are sources that have an indicator light that turns green when it is working and gives us an important clue when something is wrong, because this light turns off or shows other colors, such as red, orange or yellow. Yeah power supply fails, or the cable, the solution is to change them.
A fault in the transformer?
The transformers also fail and, consequently, the laptop battery will not be able to charge. How to know if what is damaged is the transformer? First of all, check if the cables are OK and the power supply, because it will be the easiest to solve and the most frequent failure. If you have already ruled out these problems, then yes, it is time to consider whether the transformer is failing.
For check if the transformer is working or faulty, what you can do is connect it to a socket that has an earth connection. Does the light come on? So it works. It does not turn on? There must be some mistake. You will have to buy a transformer and, if you are not very expert, it is best to take the laptop to your trusted computer technician so that he can find the transformer and make the change for you.
Is it the battery that is failing?
Finally, we are left with the last item of laptop hardware that may be failing. if the battery does not charge and it is, indeed, the battery itself. To find out if the answer is here, the first thing you have to do is turn off the laptop, unplug it, remove the battery and put it back, plug in and turn on. So you can see if the battery makes contact with the computer.
A veces the battery fails because the contacting pins have accumulated dirt. Cleaning solves the problem. For a correct and prudent cleaning, use some cotton swabs and dab them with a little alcohol. Wait until it is completely dry, and only when it is, reconnect everything.
On the other hand, it may seem like a no-brainer, but just in case, check that the laptop's charging cable is connected to its port. Perhaps, somehow the cable came out and you did not connect it correctly, since this happens more times than we imagine.
By the way, the connectors also have to be clean so that the battery charge is carried out correctly.
Software glitches that prevent the laptop battery from charging
Charging problems are almost certainly due to hardware issues, but software should be kept an eye on to take care of the laptop and prevent battery damage. For example, that the drivers battery packs are out of date, or Windows. So, you have to update them.
Another explanation is that the battery is wrongly calibrated. You will have to calibrate it again. To do it:
- Charge the battery to 100% with the computer turned off.
- Once loaded, turn on the pc and go to settings to check “on Balanced”.
- Now configure so that the screen does not turn off. And it requests in the settings that the computer does not do anything when the battery is low.
- Select that, if the battery level becomes critical, what the computer should do is “hibernate”.
If none of these solutions work for you and Doesn't charge laptop battery, the only option you will have is to buy a new battery.
