The battery of your laptop is what makes it portable and easy to use as you can carry it anywhere and continue with your work. There are three types of batteries available in the market these days.

1- Lithium-ion (Li-Ion) 2- Nickel-metal hydride (NiMH) and Nickel

All these batteries have different features but Lithium-ion is the most commonly used battery type in laptops, if your laptop battery is made up of lithium io then follow the steps mentioned below to check your laptop battery. Make sure that you follow them properly to get the best results.

1- You will have to unplug your laptop from the power switch or ay power bank.

2- Ensure that your laptop battery is placed inside the laptop properly (you can open up the back to check for alignment).

3- Now turn on your laptop and see if the laptop turns on. and if it does wait for a few minutes to check the battery drainage. if the battery gets drained at a faster rate then your battery needs to get changed.

4- And if your laptop does not work after removing it from the power but it turns on as soon as you plug it in – it also means that your battery needs to get replaced (your charger is obviously good to go).

in case your laptop’s battery turns out to be faulty, you can get it replaced by the manufacturer of your laptop is still in a valid warranty. if not, then you can get a decent deal out of an online store like Amazon.

Just make sure that you buy the right battery (your laptop can get damaged if you install the wrong type of battery in it).

Laptop Charger

A laptop charger is as important as your laptop battery if not more. You get one as part of your laptop package. But most of the chargers have a limited life and you have to replace them with a new one after a year or so.

however, it is hard to tell if your laptop battery or your charger is malfunctioning. Here are some tips on how to check your laptop battery charger.

1- This one is as easy as it gets. Just connect your laptop charger to the power and check for the light to come on(it will be placed on the main charger).

2- If your laptop charger does not have a light indicator then just connect it to the laptop and check if it gets a charger. it is best if you wait for the laptop to get charged and then notice if the battery holds up.

If the light indicator turns on but the laptop does not get charged, the problem might be in the plug that goes inside your laptop. In both cases, you need to change your laptop battery charge as it is harmful to your laptop to use a faulty charger.

You can get your hands on a new laptop battery charger by contacting your manufacturer of just ordering it online (like we all do). However, make sure that you put in the right credentials (laptop name and specs) when ordering the charger. Because plugging the wrong one can harm your laptop.
