Useful Guide: How to Replace Laptop Battery?

When it comes to the laptop, the battery plays a crucial role in determining the overall performance of the device. With time, the laptop battery loses its ability to sustain power and charge up to 100%.

The laptop battery is an integral part of your laptop. The laptop battery tends to get drained out after a few years of use. It gets worse when you take it to various locations. 

If it is not functioning properly or if it is damaged, you might need to buy a new one. This blog helps you with the general guidelines required to replace the battery in a laptop. So, let us discuss how to replace laptop battery.

Steps to Replace the Laptop Battery

Purchase a new battery

Before you begin the process of opening up your computer, first order a battery replacement. It’s important to do this step even though HP offers online support for ordering a new battery for your computer because you need to not only ensure the correct fit but also that it matches your particular model laptop or desktop.

You can find out if your computer manufacturer by accessing the “System Information” menu from the “Start” menu on a PC, or by monitoring certain registration numbers listed in specific sections of the device under Device Manager.

Once you have determined what brand and model number your computer is, search for that same information in full when entering into an online store along with “battery.” This will help you determine if they carry what you are looking for.

If you’re not sure how to find a replacement battery for an HP laptop, you have multiple options available. While OEMs often provide tools that can help users identify which model of battery they need, users may also wish to conduct outside research.

For example, Amazon features hundreds of products related to HP laptops whereby third-party entity sellers are providing replacement batteries for these systems.

We need to examine the different kinds of computer batteries and how much they usually cost, depending on where you buy them from and how old your laptop is.

It’s especially important not to overpay for a battery when there are so many other variables to take into account, such as how expensive it will be to repair or replace your current laptop if something unfortunate happens to it.

Create a battery report in Windows

Before you replace a computer battery, it is advisable that the current state of the battery be reviewed. It is useful for technicians to have a report of this so they can be better informed of what parts are more susceptible to problems over time-based on records.

In order to review the state of a battery from Computer Management, follow these steps: Right-click on My Computer and select Properties from the list. This will launch the System Properties window.

On the Advanced tab, click on Environment Variables and then New. In this new window write “powercfg/battery report” and hit Enter.

The report will display after a moment which will detail how well the computer has been managing its battery use lately. To view more information about this report type in powercfg/list in an elevated command prompt mode on your computer’s desktop.

The report provides an overview of your computer’s battery life. Design Capacity refers to how many milliamps are used during all three charging cycles on the barrow whereas Full Charge Capacity for this cycle refers to how many milliamps are available after charging your computer to a maximum of one time.

If you find that there is a large difference between the Design Capacity and the Full Charge Capacity at any given time, then it’s likely that you’ll need to replace your battery.

Disconnect your laptop from the power source

At this point, your laptop is safely powered down and free of all power outlets. However, it should be noted that should you set up this device to hibernate rather than sleep, it will continue to sip energy away even when fully powered down.

Rest assured, however, that there are other ways through which you can absolutely shut your laptop down for good! For example, booting into safe mode or doing a hard reboot will ensure that the computer does not unknowingly discharge its battery during periods of inactivity.

Remove the back panel of your laptop

A majority of HP Laptops require the removal of the back panel in order to replace a battery. There are kits that can make this process much more convenient and they’re quite inexpensive.

One such kit is compared and you will be able to see those three most common tools; we recommend getting one with both a flathead screwdriver and Phillips-head screwdriver.

All you will need to do is unscrew any metal backplates but if your laptop model has any rubber covering it might not be so easy – do whatever is necessary in order to remove it.

A plastic tool for opening things safely is your best option when reducing any unnecessary damage or unneeded stress on components by simply prying off whatever may be in the way with just a little bit of caution and put in due effort within one’s own capabilities.

Use the Phillips screwdriver to loosen the screws on the back panel of your computer. Then gently separate the back cover from your laptop so you can access the components inside.

This should be removed all at once, but for extra care, choose a corner in which to start and begin loosening it before carefully moving onto another one – do not purposely pull it off in haste! Make sure to take care not to damage any internal components while doing this.

Connect your new battery

You can begin the process by inserting your new battery back into your device. Now that you have replaced the battery, you need to reverse the steps you used in order to get your computer back up and running.

First, connect the electrical wire to the battery. Next, make sure it is completely screwed onto your computer’s body without being too tight, or else it could damage some of your device’s components.

Replace the back panel

Create a small gap between your laptop and its back cover before reattaching it to your computer. While holding the device, tighten down the screws on the laptop so that everything remains tight but not too tight.

Replace any missing rubber footings that may have fallen off your computer if it arrives without them.

Confirm performance with a new battery report

When everything is working and running the way you like, plug it into a power source. After a few minutes of charging, turn on your computer to make sure everything starts properly.

If your computer appears to be working properly, you will want to check out that Battery Report again to see if your Design Capacity has changed.

Similar to if a laptop or phone has a low battery, after replacing the old one with a new one, the Design Capacity won’t start at 100% – but rather something else which is lower than 100% for obvious reasons.

But even so, if it all looks the way you would expect from a device that had is an older worn-out battery replaced with a newer one with proper specs that’s in good condition then congratulations! It’s ready for use again – this time with its correct battery life.
