A laptop can work perfectly fine without a battery. But it needs to be connected to the power outlet via power brick to function. And as soon as you take the power plug out, the laptop will shut down immediately as a desktop computer would.

A laptop without a battery works very similarly to a desktop computer; it runs on power provided by a power outlet.

So, if you are in a scenario where you have a laptop without a working battery, you can put your mind to ease and just plug the laptop in a power outlet. It will function as a typical laptop would. The only difference would be that the laptop will now be dependent upon the power outlet to work.

Of course there will be no power storage. So, you won’t be able to take out your laptop and use it portably as you normally would.

It is recommended that you get a laptop battery as soon as possible (here’s our guide to finding a safe third-party laptop battery).

A laptop without a battery pretty much defeats the reason to own a laptop in the first place. A laptop with even a 1-hour battery backup is better than a laptop that doesn’t have any battery backup at all. We have laptops without batteries, and we call them Desktop computers.

There is no point in sacrificing performance by buying a laptop instead of a desktop computer if you don’t take advantage of the one thing that a laptop offers over desktop computers, i.e., portability.

How does a laptop work without a battery?

Laptop batteries are power storage devices. So, when you plug a laptop with a working battery into a power outlet, the laptop directs power to the battery to charge it. And then uses the energy from the battery to power the laptop itself.

Laptops are designed in a way that they can charge both when being used and when not being used. So, when laptops are not being used, their battery is getting charged if it is plugged in. But sometimes you need to work and charge your laptop battery as well. In that case, your power goes to the battery, and the laptop is powered via the battery.

While batteries are an essential component of a laptop, they are not necessary for a laptop to function. As long as a laptop has some supply of energy, it will keep working normally. Suppose there is no battery to receive the incoming power from the laptop charging brick. In that case, the laptop will use that power to directly power the components inside the laptop.

Running a laptop with battery vs. without a battery

There are no major differences between a laptop running on a battery vs. a laptop running without a battery. In fact, both laptops will function almost identical. The one difference would be that you will need to be careful since a laptop without a battery is always at risk of power loss if the AC adapter is disconnected.

So, you will need to be extra careful about plugging your AC adapter into the laptop. As the laptop doesn’t have a battery as a power backup, it will shut down immediately without any source of power supply.

Laptop charging ports are known to break down from wear and tear of usage. And so, they are notorious for getting unplugged without any warning. So, if your laptop has such a power port that even touching the AC power adapter wire unplugs it, you need to secure your power cable. So there is no possibility of accidentally cutting power to your laptop.

Is it safe to use a laptop without a battery?

Yes, it is completely safe to use a laptop without a battery. There are no downsides or any hazards of using a laptop without a battery. Since the laptop functions the same with or without a battery. In the case of using a laptop without a battery, it’s obviously not portable anymore. But other than that, there won’t be any difference between a laptop with a battery plugged vs. a laptop without a battery plugged

So, you don’t have to worry about damaging your laptop if you plug in your AC power adapter and use it without a battery. The electronics inside the laptop will function the same without a battery.

Is there any advantage to using a laptop without a battery?

There is no particular advantage of using a laptop without a battery. Since a laptop functions the same with or without a battery. In some cases, you might see a little bit of a performance boost, especially in older laptops that would reduce performance to save battery power. If you are running a laptop without a battery, you get to use all the power that the AC power brick is able to give you.

But honestly, you can get that performance without removing your laptop battery. Most laptops now have performance settings that allow you to use the max available performance. And you can take advantage of the extra performance as well by just plugging in your AC power adapter while you use your laptop.

So no, there is no particular advantage of using a laptop without a battery.

Why do people use a laptop without a battery?

Generally, when most people use a laptop without its battery, it’s more often out of necessity rather than choice. The most common reason is that their laptop battery has gone bad, and they are in the process of getting a replacement battery. While they wait, they still need to use their laptop. So they just plug the laptop into their AC power adapter and use the laptop as a desktop computer.

Other times it could be because someone has loaned their battery to a friend for a few days. Regardless it is important to note that using a laptop without a battery is almost always out of necessity.


Simply put, you can use your laptop without a battery perfectly fine. There are no dangers of damaging your laptop or starting a fire. Any laptop is perfectly capable of running without a battery. The only thing you need to keep in mind is that as soon as you disconnect the laptop AC power adapter, the laptop will shut down. Since it does not have a battery for backup power.

Personally, I believe that you should get a replacement battery as soon as possible. There is not much reason to own a laptop without a battery since you give up the portability advantage of using a battery. But for some reason, you have to use a laptop without a battery for a while; you should be completely fine plugging it in your AC power adapter and using it normally.
