Can A Laptop Run Without A Battery? (How To Safely Do So)

Batteries age over time and can become faulty or unreliable. When technical tragedy strikes, unfortunate laptop users may want to use their laptop while they wait for another battery.  

Can a laptop run without a battery? We break down the facts and how to do so safely in this guide. 

In short, yes – but you will need to take precautions. When using a laptop without a battery, it is vital that you plug it into a reliable outlet securely with a functioning adapter.  

Ideally, an intact original adapter that came with the laptop would be best, but we work with what we have.

With this method, your laptop works similarly to a PC and will run fine but will also shut down if unplugged. This removes its portability but means that you can still use your laptop without a battery.  

Removing a battery does not always need to be a last resort.

Some people remove their laptops when their laptop is not being used for a while to avoid overheating or to avoid damaging their laptop with a faulty battery.

Precautionary Measures When Using A Laptop Without A Battery

Make Use of a UPS or a Power Backup Device 

A UPS, or uninterruptible power supply, or a power backup device protects you from power surges as well as loss of power. These devices ensure that you will not lose data from forces outside of your control. If you live somewhere where power cuts are frequent, a UPS or power backup device is essential.  

Keep The Charging Cable Intact 

Once your charging cable is in, we do not recommend moving it or separating the brick from the cord. Even lightly nudging the cable could cause a momentary loss in power, which could in turn cause you to lose your work in a sudden shutdown. Keep your cable intact and still, and manually shut it down once you are done working.

Keep The Battery Slot Clear 

Is it safe to run a laptop without a battery? Keeping your battery slot clear of potential blockages is essential to its health and long-term functionality. We also must recommend that you do not touch any exposed battery connectors as you could become electrocuted. Be sure to keep these battery slots away from curious children and animals for maximum safety. 

Use The Original Adapter 

If you do want to use a laptop without a battery, it would be ideal if you could use your original charger. Power variations could be harmful to the internal components of your laptop, and the original power adapter (or identical substitute) helps lessen the effects of them. If you do not have your original adapter, a functional, secure, and intact one should work as well.
