You can use laptop without battery

A laptop’s battery is extremely important. But can we do without it? Everything you need to know in this article.

The core element of a laptop is its battery. And sometimes it has to be removed. It can happen that an old battery no longer charges at all or that it deforms until it becomes dangerous. When the battery is removed, the next most logical step is to replace it. But is it possible to simply do without it? The answer is yes (but it depends).

A laptop is still a computer. It does not need a battery to power all of its components and these various components remain present when you remove the battery. A computer uses an external power source to operate, like your laptop. The charger is not only there to recharge the battery when it is almost empty. When you connect your laptop to the mains, the energy comes from the charger and no longer from the battery. We see it in macOS in the battery settings, with “Battery” as the power source and as soon as you plug in the machine, the mention “AC adapter” appears.

The YouTuber Ask A Computer Geek has a very interesting video on the subject: he disconnects the battery of his laptop to show how it stays powered and works on mains. Of course, nothing happens when the power is disconnected, as with a stationary computer.

Not all laptops are created equal

This may be the case for machines Windows, but on macOS, that’s a different story. Even though macOS tells you it’s running on the power adapter when you plug in the device, it’s not advisable to use a MacBook without battery. The machine might not even work at all.

If you manage to start a MacBook without a battery, you’ll feel like it’s aged five years. This is because the operating system, recognizing the lack of battery, intentionally slows down the processor. Everything remains operational, you can use the machine, but the experience will be significantly slowed down.

In fact, it is better not to give it a try. If you need to remove the battery from your MacBook, replace it. And again, this advice applies to all laptops insofar as the total removal of the battery loses the main interest of the laptop, its portable character, precisely.

But the subject of this article isn’t whether or not you should use a laptop without a battery: it’s about whether you can. And we actually can. If you’re using your laptop without a battery, either to save money, because you’re waiting for a new one, or because it sounds cool, there are a few to keep in mind.

To get started, be sure to use the charger that came with the device. Without a battery, the power supply must be strictly identical to that intended by the manufacturer. The slightest change in power represents a risk since there is no backup battery to take the hit.

You also have to be very careful with the data present now that you are only operating on mains power. In the event of a power outage, or if you pull the plug, your laptop will shut down instantly, putting the entire system at risk. Save all the time. Better yet, use software with automatic backup.

Also, remember to turn off your machine completely before unplugging it. You might be in the habit of removing the plug before leaving the room, which you can’t do in this case for several obvious reasons, but you should make sure the machine is 100% off before taking it away with you. If it’s still shutting down when you unplug it, you could damage it.
