1. Use the USB Port


If you have a laptop, then you are likely familiar with the hassle that can come from trying to charge your battery. Your battery dies, and now, you’re stuck with no way to power your laptop. The good news is, there are a few different ways that you can charge your laptop without having to plug it into an outlet. 

One of these methods is by charging it through its USB port. Every laptop comes with multiple connectivity ports, including at least one USB port. To charge your laptop using a USB port, simply plug one end of a USB cable into your laptop and the other end into either another device or an external battery pack. 

However, make sure that you are using the USB Type-C port for charging purposes, as it is the only USB port that can take power input and charge your device. But, it should not be a problem for you since most laptops these days come with a USB Type-C port. 

2. Get an External Charger


Using an external charger is a pretty handy way if your laptop is not picking up its own charger. Just take the battery off of your laptop and connect it to a compatible battery charger. Wait for a few hours before putting the battery back in the laptop. Once the battery is back in place switch on your laptop, and you should be good to go. 

But this method will only work if your laptop comes with a removable battery. As there are some devices in the market, especially the new ones that don’t feature a removable battery. So you should keep that in mind before buying an external battery charger for your laptop. 

3. Try a Universal Power Adapter


The universal power adapter is a great way to charge your laptop battery if you don’t have a laptop charger handy, or if you want an extra power source. The universal adapters come with different voltage capacities that they support. Thus, you need to make sure you are getting the right one if you don’t want to damage your laptop due to high voltage.  

To use the universal power adapter, plug the adapter into your laptop, then plug in the charging cable that you have and connect it to the power outlet. You should see the light on your laptop start blinking – this means it is charging.

Universal power adapters are a pretty handy option if no other method is working for you. Plus, to your advantage, you can find a universal adapter in the market at a pretty cheap price. Thus, getting it should not be an issue for you. 

4. Use a Power Bank


If your laptop is not charging, you may have a bad battery or a bad charger. But before you invest in a new charger, try charging your laptop with a power bank. You will need to plug the power bank into your laptop’s USB Type-C port for it to charge your device.

However, not all power banks can charge a laptop, and not every laptop is made for the purpose of charging the laptop; thus, you will need to make a new purchase. Plus, also make sure that the power bank that you are getting has a high power capacity so that it can at least charge a laptop completely once before dying itself.

One problem that you might come across if you have an older laptop is that it might not have a Type-C port. Thus, use an adapter for that or try any other method. 

5. Use Solar Charging Kits


If you want to charge your laptop battery in the sun, you can use a solar charging kit. The kit contains solar panels and an inverter, which will convert the power from the sun into electricity for your laptop. When choosing a solar charger, consider how much wattage it has. 

This is usually measured in watts, and the higher the wattage, the quicker it will charge your laptop battery. But if the voltage supper is too high it can damage your laptop as well. Other considerations when choosing a solar charger include where you live and how often you plan on using it. 

For example, if you live in an area with less sunlight or if you need to charge your laptop battery frequently, there are solar chargers that have more wattage (and; therefore, faster charging). However, if these factors don’t apply to you and you just need a cheap and efficient way to manually charge your laptop’s battery then choose one with lower wattages. 

The solar panel must have sufficient surface area for collecting energy efficiently- about 10 square feet should do the trick. These kits typically come with all the tools necessary for installation- be sure not to forget these.

6. Use Super Battery

A great option is to get a super battery. All you need to do is buy a super battery, remove the battery from your laptop and replace it with the new one. The super battery does not work with the laptop’s charger; thus, you don’t need to worry about your broken charger. These batteries come with their own charger and work perfectly with laptops. Thus, using them with your system should not be a problem for you.

How to check laptop battery charging circuit?

Plug the power adapter into your laptop. If you are using a battery, connect it now. Make sure that you have not plugged the power adapter into an extension cord or surge protector. Note that some laptops have a separate battery charger and do not need a power adapter to charge their batteries. If you are using an extension cord, make sure it is rated for high-power use and plugged directly into a wall outlet.

If your laptop still does not start charging, unplug it from the power source and disconnect any peripherals, such as a mouse or USB keypad. Try booting up your computer without these accessories attached. If that doesn’t work either, then you may have a motherboard problem with your laptop and will need to take it in for service.


You can charge laptop battery manually by following these simple methods given above. First, you should check the charging circuit on the laptop and make sure that it is not loose or damaged. If it is loose, or if there are any other problems with the circuit, then you will need to replace it with a new one before continuing.

You can also use adapters, external chargers, and other options if you have a bad charger and if your laptop is not charging. These issues should solve your issue and should allow you to charge manually. However, if the issue is with your laptop and not the charger, then you will help to get some professional help for your device.
