When Should I Replace the Battery in My Laptop?

A sudden shutdown without warning signals that your battery has reached the end of its useful life and must be replaced. Uncharged batteries may signal that the battery is nearing the end of its useful life.

When these issues begin to manifest, it is always a good idea to perform a battery calibration; calibration will provide you with a better understanding of your battery’s status and will assist you in determining whether or not it is time to replace it.

This article discusses how to determine whether a laptop battery is dead, how to inspect and test its health, and when to replace it.

How to Know if Laptop Battery Is Dead or Not?

Know if Laptop Battery Is Dead or Not

To begin, it may be rather simple for some to determine whether your laptop’s battery is dead. Your laptop will not turn on if it is dead, correct? Wrong! If you’re like me and spend the most of your time plugging in your laptop, you may be unaware that your battery is low.

When plugged in, your laptop operates on AC power rather than battery power. Thus, as long as your laptop is connected, it will continue to function even if the battery is depleted.

If you attempt to detach your laptop, the battery runs out and dies unexpectedly. Regrettably, your battery has expired.

At this point, there is no way to correct it. Simply visit the website of your laptop manufacturer (if you have a warranty on your laptop) or good old Amazon and get a bright new battery for yourself.

Bear in mind that batteries are not designed to last indefinitely but rather to be used. As a result, your laptop’s battery will eventually degenerate and die.

This is when your laptop’s warranty kicks in. My Asus ultrabook’s guarantee included a free battery replacement throughout the first two years.

Although the battery was still in good condition near the conclusion of my warranty, I decided to take advantage of the offer, and so I purchased a battery from Asus. The conclusion of the storey is this: you paid for the guarantee; take advantage of it!

Is the battery about to run out?

Now, if you’re a lucky man and your battery hasn’t died yet, you can check to see if it’s dead. When your laptop is connected to a power source, click the battery icon in the taskbar (Windows).

If you notice that your battery charges partially and then stops charging, this is a good indication that something is wrong with your battery.

You should begin by adjusting your battery. Calibration entails completely discharging and then recharging your laptop’s battery.

It enables the battery to reset and perform a self-diagnosis to determine the remaining energy in the battery.

Battery Calibration is a common diagnostic technique that should be performed on a somewhat regular basis to verify the condition of your laptop’s battery. Don’t be concerned if you’ve never done something before and now know how!

On certain computers, the manufacturer offers a tool that automatically adjusts the battery for you. Please consult your laptop’s manual or the manufacturer’s website to determine whether this utility is installed.

If you do, simply allow this software to modify your laptop for you. It takes some time (about three hours on my laptop), so do not be scared.

What to Do If Your Battery Is Dead?

Check your warranty to see if you qualify for a free repair or order a replacement laptop battery online. Batteries might be quite affordable, depending on the model of your laptop. The majority of feasible replacements cost around $20 or less.

When shopping online, ensure that the battery you select matches your laptop model precisely. I discovered this the hard way when I purchased a battery that did not work with my laptop.

Symptoms of Laptop Battery Damage

Unfortunately, computers do not last indefinitely. The battery is the most frequently failed component of a laptop. At any time, battery failure can occur without notice.

Additionally, you receive unique pre-warning indicators, allowing you to upgrade before your machine becomes inoperable. There are approaches available to individuals who use a laptop to determine whether their battery need replacement. Consider the numerous symptoms to watch for.

1. Windows Will Warn You

Specific computers, as a result of advancements in computer technology, now include a new feature that indicates when the battery capacity is critical.

When a computer’s battery is critically low, a red X appears on the battery symbol. If this occurs, you may also receive a message when the battery icon appears, stating, ‘consider replacing your battery.’

This is most frequently encountered in Windows 7 and higher generations. This is an excellent indicator that your battery is nearing the end of its life.

2. Does not accept the charge it uses

Another reliable indicator that your computer’s battery is nearing the end of its life is when you charge it overnight.

Batteries that fail to discharge their charge after prolonged charging times are a strong indication that something is wrong.

In general, people leave their computers plugged into the mains electricity all day. However, this may eventually result in a fire hazard. If your laptop battery stops charging, it’s time to consider a replacement.

3. Your computer quickly overheats

In some cases, if your laptop rapidly overheats while performing routine operations, this may be an indication that your battery is nearing the end of its life.

If your battery consumes more power to run your application, it can place additional strain on the other internal components of your computer. As a result, your computer may overheat, posing a serious fire danger. Is your computer overheating?

4. Sudden Shut Down

Occasionally, when a battery dies, the laptop will shut down abruptly. Due to the rapid shutdown, the battery is particularly stressed when the computer is running, and the essential power cannot be generated.

Sudden shutdowns are extremely inconvenient, much more so if your job has not been saved.

How to Tell if Laptop Battery or Charger Is Bad

The charger and battery of the laptop are critical components. Without a charger, you will attempt to charge the laptop in every way possible.

Additionally, the battery is critical because the device is portable. By examining the charge indicators on the laptop, you can verify whether or not the charger is defective. Additionally, you can identify a damaged battery by running software or by connecting the laptop.

Nothing can be done to repair the battery. However, the charger can be secured by replacing the adapter’s voltage IC card.

How to Check Laptop Battery Health Windows 10

Batteries power many of our favourite electronic products, but they do not last indefinitely. The good news is that Windows 10 laptops have a battery report that indicates if your battery is still functional or nearing the end of its life.

With a few simple keystrokes, you may create an HTML page containing battery usage data, capacity history, and life estimates. This report will inform you far in advance of the possibility of failure if it is in need of replacement.

1) Generate PowerShell Battery Report

A battery report is generated using Windows PowerShell, a built-in command-line programme that you have never used before. The simplest method is to right-click on the Start icon and select Windows PowerShell (Admin). Permission to make device adjustments may be requested via a pop-up window; confirm.

The blue PowerShell command window will appear, allowing you to type commands automatically in Windows 10. To begin the command, type or paste powercfg /batteryreport /output “C:battery-report.html” into the box and press Enter.

PowerShell will notify you of the name and location of an HTML battery life report that has been prepared on your PC. Battery-report.html is called in this case and has been stored to the C disc. You can now securely exit PowerShell.

2) View the Battery Report

To use Windows File Explorer, open and access the C disc. Save the battery life information as an HTML file. Double-click the file to open it in your preferred web browser.

The report details the condition of your laptop’s battery, its capacity, and its life expectancy. The Battery Report will display basic information about your system at the top, followed by battery data.

Take note of the current use section whenever the laptop is powered by batteries or an AC adapter. Each drain is monitored over the last three days in the Battery Use section. Additionally, the Usage History section contains a full history of battery utilisation.

The capacity history section of the battery depicts the evolution of the battery’s capacity. On the right is the capability for design, or the manner in which the battery is supported.

On the left, you can see your laptop’s current overall charging capacity, which will likely decline over time as your device consumes more power.

This takes us to the section on estimating battery life. On the left, you can see how long the design capacity is expected to last; on the right, you can see how long it really lasts.

The report concludes with an up-to-date, final battery life estimate. In this circumstance, my PC is designed to run at 6:02:03 a.m. but is currently running at 4:52:44.
