This article covers How to know if laptop battery is dead, how to inspect and test its health and when it’s time for a replacement.


How can I know if the laptop battery is dead?

First, it could be relatively straightforward for some to see whether your laptop battery is dead. Your laptop won’t come on if it’s dead, right? Wrong! If you’re like me, and you’re most of the time plugging your laptop, you might not see your battery is dead.

When it’s plugged in, your laptop runs on AC power and not the battery. So your laptop will still work, even if your battery is dead, as long as it is connected.

If you try to disconnect your laptop, your battery is dead and suddenly dies without notice. Sorry, but your battery has passed on. 

There’s no way to fix it at this point. Just go to the site of your laptop maker (if you have a laptop guarantee) or too good old Amazon and acquire a bright new battery for yourself.

Remember that batteries are not intended to live forever but are intended to be utilized. So, your laptop battery will begin to degrade at some point, and it will die.

It is when a guarantee on your laptop is applicable. The warranty on my Asus ultrabook arrived in the first two years with a free battery replacement. 

The battery was still okay toward the end of my warranty, but I wanted to use the offer, so I got a battery from Asus. Story moral: you paid for the guarantee; utilize it!

Is the battery going to die?

Now, if you’re a lucky man and your battery doesn’t bit the dust yet, it is possible to verify if your battery is out. When your laptop is plugged in, click the battery symbol in your taskbar (Windows). 

If you see that the battery only charges part of the way and does not charge further, this is a decent indication that something goes on with your battery.

The first thing you ought to do is adjust your battery. Said, calibration implies that your laptop battery is almost entirely discharged and then reloaded again. 

It enables your battery to reset and to make a self-diagnosis to see the amount of energy left in your battery.

Battery Calibration is a standard diagnostic procedure that should be carried out relatively frequently to ensure your laptop battery is healthy. Don’t worry if you never did that before, and you know that now!

The manufacturer includes a tool to adjust your battery for you on some computers. Please check your laptop handbook on the manufacturer’s website and see if you have this utility. 

If you do, just let your laptop adjust for you using this software. It takes some time (for my laptop, around 3 hours), so don’t be alarmed.

If Your Battery Is Dead, What to Do?

Check your guarantee to check whether you have a free replacement or purchase your replacement laptop battery online. Batteries can be pretty cheap, depending on your laptop. Most reasonable substitutions amount to about $20 or less.

Make sure that when you browse online, the battery you choose fits exactly the laptop model. I’ve learned the hard way and bought the battery that didn’t work with my laptop.

There is nothing that can be done about fixing the battery. However, the charger can be fastened by replacing the voltage IC card in the adapter.

You may create an HTML file with battery use data, capacity history, and life estimates with a few simple keystrokes. This report will notify you long before you have a chance of failing if it needs to be replaced.

The Windows PowerShell battery report is generated, a built-in command-line tool that you never used before. The quickest option is to right-click on the Start icon and choose Windows PowerShell (Admin) from the menu. A pop-up window can ask for permission to make device changes; say yes.

The blue PowerShell command window will emerge so you can automatically type commands in Windows 10. Type or paste powercfg /batteryreport /output “C:\battery-report.html” in the box and hit Enter to start the command.

PowerShell will inform you of the name and location of a created HTML battery life report on your PC. In this scenario, battery-report.html is called and has been saved on the C disc. You can now close PowerShell safely.

Open and access the C drive for Windows File Explorer. The battery life report should be saved as an HTML file. Click the file double to open it in your favourite web browser.

The report describes the status of your laptop battery, how good it is, and how long it can last. You will notice basic information about your machine at the top of the Battery Report, followed by battery data.

Every time the laptop is battery powered or hooked to AC power, take note of the current use section. Each drain is tracked in the Battery Use section throughout the last three days. A comprehensive history of battery use can also be found in the Usage History section.

The capacity history portion of the battery illustrates how the capacity has evolved. On the right is the design capability or the way the battery is supported. 

On the left, you can see the current total charging capacity of the battery on your laptop, which will probably decrease as your device uses more time.

It brings us to the section on battery life estimations. At the left, you’ll see how long the design capacity should last; at the left, you’ll see how long it lasts. 

At the end of the report comes a current, final battery life estimate. In this scenario, my PC is 6:02:03 a.m. at design capacity but is currently 4:52:44.
