What happens when the laptop battery runs out? [UPDATED]

Laptop’s battery is one of the most integral components of an electronic device. It is designed to give us mobility and to work whenever and wherever we are until suddenly it no longer keeps a charge.

When the battery runs out, our work suddenly grinds to a halt and the laptop becomes completely unusable until it’s connected to another power source.

Not only that, but depending on its age, the battery can take a long time to charge back up before you’re able to continue working on your tasks.

Fortunately, the modern world offers many alternative ways for us to work on those tasks without having to wait for our laptops’ batteries to recharge. Read more to find out how you can continue working even when your laptop battery runs out.

What happens if I let my laptop battery run out?

If you do not properly care for your laptop battery, it can become damaged and may not be able to hold any charge. If you let your laptop battery run out completely, it will cause irreversible damage to the battery’s cells. This damage is caused by a process called deep discharge cycling, which occurs when a Li-ion battery is completely discharged and recharged many times. When this happens, the chemical structure of the individual cells in the battery are corrupted, making them unable to store electricity.

In addition, allowing your laptop to reach 0% charge can cause voltage instability, leading to your laptop becoming unresponsive or crashing. This can have damaging effects on other components connected to the motherboard such as memory modules and hard drives. To prevent these issues from occurring, it is important to ensure that you regularly use and recharge your laptop’s battery as opposed to letting it drop too low or run out completely.

You should avoid leaving it plugged into an outlet for extended periods as well as limit charging from 0% – 100%, only topping up the charge when necessary; instead, try to keep it between 20-80% whenever possible to prolong its life span. Furthermore, when not in use for long periods or during storage make sure you keep the charge between 40-50%. Keeping your laptop’s batteries in good condition through proper handling will help ensure that its performance remains optimal over time.

Is it OK to run laptop without battery?

It is not recommended to run a laptop without a battery. Laptops use both the AC adapter and the battery as sources of power, with the battery usually providing supplemental power when it cannot fully keep up with the current demand.

Without batteries, laptops are more prone to power outages or voltage spikes that can cause damage to their components due to unexpected shutdowns. In addition, running a laptop without a battery can reduce its overall lifespan.

The constant strain of providing power through the AC adapter means that components such as capacitors and resistors will wear out faster than they would normally, reducing their overall life expectancy and leading to potential damage down the line.

Additionally, running laptops without batteries can lead to an increased risk of overheating, which can cause further damage or even permanent failure if left unchecked. Therefore, it is best to always utilize the laptop’s embedded battery to protect against potential issues caused by unexpected power outages or voltage surges.

How To Tell if Your Laptop Battery Is Dying?

So, you’ve got your laptop computer. You take it everywhere and use it often but have you ever thought about how the battery might be faring? The truth of the matter is that laptop batteries can last a long time, but eventually, they do need to be replaced. Here are 5 ways to tell if your laptop battery is dying. 

Decreasing Run Time – One of the most obvious signs that your laptop battery is dying is a decreasing running time. If you used to get four hours of run time and now you’re only getting two, then it’s probably time to replace your battery. This could also mean that something else in your computer isn’t working correctly, so make sure to do some troubleshooting before investing in a new battery. 

Swelling Battery – A swelling laptop battery is an indication of a serious problem with the cell inside your battery or with its charging system. This can happen due to overcharging or because of damage caused by extreme temperatures or physical impact. You must stop using the laptop immediately if this happens as it can cause permanent damage to your computer if left unchecked! 

Weak Connections – Over time, dirt and dust can accumulate on the connections between the laptop and its charger which can impede the flow of power into the machine. Be sure to check these connections every few weeks and clean them accordingly if necessary this will keep them working properly and prolong battery life significantly! 

Slow Charging Times – Another sign that something might be wrong with your laptop’s battery is slow charging times when connected to its charger for long periods (i.e., overnight). If this happens, then it could indicate an issue within either the charger itself or with one of its components (like a faulty cable, for example). In such cases, it might be best to buy a new charger instead of replacing the entire battery unit outright!  

Unusual Noises – Finally, another way to tell if something is wrong with your laptop’s battery is by listening closely when it’s plugged in and charging; unusual noises may indicate problems with either its internal components or its connection point on the motherboard (or both!).

What To Do if the Laptop Battery Is Dead?

When you’re trying to get work done or relax with a movie, the last thing you need is for your laptop’s battery to die. It can be frustrating and inconvenient but don’t worry. Several possible solutions may help you out if the laptop battery is dead. Let’s take a look at several of them. 

Replace the Battery: First, check if it’s time to replace the battery altogether. Check the owner’s manual for instructions on replacing the battery and make sure you purchase one that is compatible with your laptop model. If your laptop is still under warranty, contact the manufacturer about getting a replacement battery for free or at a discounted rate.

Check Your Settings: If your laptop has been used on an inconsistent basis, it may have gone into power-saving mode as a result of inactivity over an extended period. Take a look at your power settings and make sure they are configured properly if they’re not set up correctly, they could be draining your battery faster than normal. You should also check if any unnecessary programs are running in the background that could be consuming extra energy.  

 Keep it Cool: Heat can damage batteries over time, so make sure your laptop isn’t exposed to extreme temperatures when it’s in use or stored away when not in use. Use a cooling pad underneath your device while using it and store it away from direct sunlight or other sources of heat when not in use. Doing this will help extend the life of your battery and ensure maximum efficiency when charging it up again.

Use Battery Optimization Apps: If you want something more hands-off, consider downloading apps designed for optimizing laptop batteries like BatteryCare or BatteryInfoView. These apps monitor how much energy each program uses and provides tips on how to increase their efficiency allowing you to get more out of each charge cycle and extending the lifespan of your device’s battery overall.

Use Power Saving Modes: Another way to conserve energy usage is by enabling power-saving modes on both Windows and macOS laptops whenever possible. These features disable certain processes such as dimming display brightness and disabling Bluetooth/WiFi connections when idle; this helps decrease energy consumption significantly without sacrificing functionality too much while still allowing you access to basic system functions such as web browsing or creating documents/spreadsheets.


When your laptop battery runs out, it can be very inconvenient since most of us rely on our laptops for work and important tasks.

If you’re stuck without a charger or extra battery, your productivity comes to a standstill. The best thing to do is to always have a backup so you are prepared in case of an emergency.

Alternatively, getting creative with problem-solving skills can help you think of ways to utilize other resources to get the job done.

Although running out of battery can be quite annoying it teaches us to be prepared and use our initiative.
