Is Using A Laptop Plugged In Harmful?

Notebooks have become popular over the years as they are great partners due to the power and durability of the battery they offer, being used anywhere for work, study or leisure purposes.

However, many people still have questions related to charging the notebook, after all, at some point the charger must be connected to the machine, since the battery life, as we know, is limited. Among the most frequently asked questions is whether it is healthy to use the notebook in the socket and whether this way will not harm the notebook.These questions are very important, after all they can help extend the life of your device. In this text, we will clarify your doubts about the act of using a notebook in the socket. Follow !


Many people still believe that using the notebook in the socket can be harmful to the battery. But is this really true? To answer this question, it is interesting to understand how current batteries work. The models present in the vast majority of notebooks have a device that controls energy storage, which deactivates battery charging when it reaches 100% charge, avoiding unnecessary wear and allowing the energy from the charger to go directly to the notebook. This is the main method used by manufacturers so that batteries no longer “addict” .

That is, when completing the battery charge, the device will be able to conclude that the charging process has been carried out and, thus, will redirect the energy from the source directly to the notebook, without involving the battery. A visual identification of this can be made through the battery charge LEDs and indicators present on the source, which change color or turn off to indicate that the charge is complete. Thus, you can be free to use the notebook in the outlet without major worries.

We can conclude, then, that using the notebook plugged in, contrary to what some users think, can be a beneficial experience for the device, as it prevents you from frequently wasting the energy cycles that are the gauges of the useful life of the battery. If you use the machine without the charger, it is recommended that the recharge be started when the battery has medium levels, such as 20%, for example.

However, avoid leaving your device plugged in when you are away or simply not using it. This means unnecessary effort for the source and does not produce any benefit that justifies the action. In fact, it’s just the opposite: appliances connected all the time to the socket are capable of harming the charger’s functioning in the medium and long term.


This is another very common question among notebook users. Many, by the way, do not even know that it is possible to use the notebook without the battery. This move has pros and cons.

Naturally, the main advantage of using the notebook without a battery is that, in this way, you are preserving its component and increasing its useful life, since the energy cycles are not being spent because the battery is not even being used by the machine.

In the field of disadvantages, it is correct to say that not using the battery in the device can put the device at risk in a sudden power outage, since the battery serves as a kind of No-Break for the notebook. Another clear disadvantage is the impossibility of taking advantage of the main characteristic and the one that differentiates the notebook from other computers: the autonomy away from the sockets.

Also, try to use the notebook with the battery at least every 15 days. When removing the component, try to store it in a suitable place, not exposed to heat or humidity, for example.


The notebook needs a series of cares to maintain its normal functioning and so that it can present an income within the expected by the user. The good news is that all actions can be done in a practical way, and do not require specific technical knowledge. Notebook care can be divided into specific areas. Let’s start with the battery.

The main battery conservation measure is calibration , which consists of charging and discharging the component three times. This will equalize the energy level of each of the cells that make up the battery structure. Thus, you will make your battery healthier and will be optimizing the performance of the component in the medium term.

It is also important to maintain a cleaning routine on the device. Sanitize your keyboard frequently. To do this, you just need to have a brush with soft bristles and soft cloths, items that will be enough to prevent the accumulation of dust. As for cleaning the screen, there are products suitable for cleaning, called screen cleaners . You can find these items in stores that specialize in this type of trade.

Another important conservation measure is to pay attention when transporting the notebook. Under no circumstances transport the device while it is turned on, as any bump, even a slight one, could damage the machine’s hard drive. And, if that happens, you run the risk of losing all of your stored information.

To move your laptop properly, ideally, place it inside a briefcase or backpack specifically designed to protect your laptop. Do not use purses or bags that are not indicated for transporting the device, as they can damage the structure and even cause the internal components to break in case of a more sudden contact.

Finally, pay attention to the software. Software refers to the programs and applications present on your notebook. The recommendation here is to try to keep the most updated versions of these programs. In addition, count on the help of an antivirus to defend against the various threats that can hit your laptop.
