What happens when using a laptop plugged into the power?

When buying a new computer they will probably give us advice on how and how much to charge the battery for the first time , that will allow the computer to work in the best way in the first moment but many doubts can arise later, what should you do next? How much should you charge it?

Is it bad that a laptop is plugged in all the time? Previously it was said that yes, but this is something completely false in the time that we are, because computers have evolved over time. If you want to know more about this, you should keep reading.

What happens when using a laptop plugged into the power?

The first thing you have to know is that laptops have a lithium-ion battery , which is not overcharged, when fully charged, as the energy will no longer circulate there, it will only charge directly to the computer, of course, we are referring to modern computers .

Older models can have overload problems when left plugged in day and night. Modern computers have a lithium polymer battery, and they have a sensor that monitors the battery so that it does not overcharge , no matter how strong the current is.

But having a few years on top these could deteriorate and their capacity will be reduced, it can cause some problems, because a plugged-in laptop tends to generate heat and that could damage the battery. We recommend you learn to measure the temperature of the computer.

How long is the correct battery life for a laptop?

Laptop batteries typically have a life span of three to five years , in which they can complete 300-500 charge cycles. Of course, that in the case that it is a battery that has not been completely cared for, while one that is ‘cared for’ may last from 1200 to 200 charge cycles.

Can the laptop work connected and without battery?

The answer is yes, the laptop can work without a battery but with a plug, so this is a benefit if you have a place where you can be quietly, now whenever you remove it it has to be between 20% to 80% charged .

Although you have to bear in mind that there are laptops that can remove the battery and there are others that have it integrated, in these of course, it is not recommended that you remove the battery, so you should unplug it for a while and use it like that. you can try activating the power saving to work better on the computer.

In the computer that the battery can be removed there is no problem, you can remove it and continue working in the best way. If you remove the battery, you have to know that you are giving the computer more useful life, since exposure to heat is what mostly damages the batteries.

Risks of doing this

In itself there is no risk of practicing this, just keep in mind that the battery being outside the laptop could discharge itself , so it is best to connect it from time to time and keep it charged within the range of 30 to 80% charge.

Does leaving your laptop charging overnight hurt it?

The answer is that there is no problem of leaving it connected for a whole night or during the whole day, because basically their battery is designed to withstand electricity, to the point that when it is fully charged it stops receiving power, but you should know that the creator brands of computers such as HP, Lenovo (official page) , Dell do not recommend its connected use.

Because there is a problem with this situation and it is the heat that it is going to receive, that is why we recommend buying a good fan that dissipates the heat or if the battery can be removed, then do it, in addition to keeping the battery on a charge ‘stable’ that is to say never leave it completely without load , but also not overload up to 100%.

How does the type of battery the laptop uses affect leaving it connected or not?

Now, it is important that you know that in the article we have made reference to the batteries that modern laptops commonly use, which is the ion battery, but if you have a laptop with an old battery, you should never use it plugged in. The best thing is that you unplug it once you have a full charge.

So yes, the battery could affect whether you can unplug it or not, although you have to know that you should not worry because normally laptops use the same type of modern battery.
