Why laptop not charging properly?

If we have a laptop, what worse thing can happen that the laptop battery does not charge? If you keep asking why is my laptop plugged in not charging hp. We would lose the great advantage that portability gives us, and it must be a matter that we have to fix as quickly as possible.

It usually is a problem that has a relatively easy solution, whether it is a problem with the battery, the charger itself, or even the operating system. So we are going to tell you all the possible solutions to solve the problem. Let's get started!


Most common problems why the laptop battery does not charge

Let's start by quickly posing the most common reasons why this problem occurs.

  • That the charger is in lousy condition: we always recommend checking that the charger or external power supply is in good condition, as it may be the focus of the problem.
  • That the system drivers are not working well: both in batteries of old and newer models, Windows has the corresponding drivers to detect the battery and manage the power.
  • That the BIOS has a bad configuration: in this case, we would have to return to the factory parameters, and it is advisable to update it to the most recent version.
  • That the battery is in bad condition: in the new generation, it is possible to check it from Windows, in case it starts clearly. If not, the easiest way to detect the problem is to know that the PC works fine when it is plugged in.

Check charger and connector.


We believe that the first step in finding out why the laptop battery is not charging is to check the charger. This gadget is nothing more than the popular heavy flask that is always on the ground, and that is responsible for getting us out of a jam when the battery starts to go down.

Charger's fault:

Let's see if its corresponding activity LED lights up

We check with a voltmeter/multimeter that it delivers the correct intensity and voltage, which are specified on the charger itself.

We place the multimeter in position 10A, for example, and measure the connector's two poles.

We do the same with the voltage, placing the multimeter in the 20V position or a coherent scale consistently above the nominal value to be measured.

The fault of the connector or the other scenarios that we will see:

If you are giving the correct measurements in the extreme, the problem is located in the equipment. We should check the poles' continuity, but it isn't very easy since it opened to disassemble the laptop.

The typical test is to gently move the connector to see if we can get it to make contact. Or try another similar charger to see if this one works. The problem could be in the charger cable, but it is also challenging to do this because it is sealed. The moral of this is to look for a charger and see if the equipment works well with it.


Reinstall Windows drivers and recalibrate the battery

After having more or less clear that the fault is not the external power supply, we will work on the configuration of the operating system to see if we can solve the problem.

The process is quite similar to calibrating a laptop battery, so let's see step by step what we have to do:


We turn off the PC in a usual way and always leaving the power connector disconnected from the equipment so that it does not receive any power and the battery is not damaged when removing it.

If we have a computer with a removable battery, we recommend removing it from it. In case we have a modern laptop, the Lithium-Polymer battery is located inside, so we will choose to leave it on if we do not want to lose the equipment warranty if it is less than two years old.

We will turn on the equipment again with the external power supply and without the battery.

Now it is time to uninstall the corresponding drivers from the operating system, so we will right-click on the start button and click on " Device Manager. "

In the list of components that appear, we are going to place ourselves at the top in the batteries section. We expand it and uninstall as many drivers as "ACPI-compatible" batteries.
