Lithium ion technology is a technological development found in laptop batteries as well as other devices including calculators, cell phones, car locks, and MP3 players.

The majority of laptop batteries are covered by two-year maximum manufacturer warranties. Manufacturers of lithium-ion technology are having trouble extending its lifespan, despite advancements in the field. As a result, no matter how well you care for your laptop battery over time, its capacity will decrease and eventually run out of power. The capacity of the battery will differ from what it was when your laptop was brand-new. 


It is therefore advised that you change your battery every two to three years. Consider a scenario in which you must carry your laptop because you are working on a critical project. In this scenario, the laptop must always be plugged in using an AC adapter. The laptop will shut down the instant you remove the AC adapter. 


Thus, you won't have time to gather your documents.Generally speaking, Windows will alert you to this as When plugged in but not charging, think about getting a new battery. It is advised to change the battery as soon as possible at this point. Aside from this, the computer can be exhibiting numerous indications that the battery needs to be changed.

I'll be showing you the 5 Signs of Laptop Battery Failure | Dead Battery Symptoms in this article. You will be able to determine whether your battery has a dead cell issue at the conclusion of the article.

Now let's discuss the subject,

1. Warning from Windows

Certain operating systems, like Windows, could not give much information about the battery they have been utilizing. However, it will undoubtedly be exhibiting the warning indicators that a new battery is required to prevent shutdowns. 

Typically, the Basic Input Output System (BIOS) uses its signals to attempt and figure out if the battery needs to be changed. If so, the user is notified by an output message. 


The signals may be interfered with for many reasons, and as a result, Windows may display fictitious messages indicating that it requires replacement. 

The Microsoft Windows 7 team has verified that the OS displays this notice due to a flaw, which they plan to address in their upcoming upgrades. The most recent Windows operating system versions have avoided this. 

To view this message, 


  1. Select the tiny battery symbol located in the System tray
  2. Look for any messages indicating that the device is not charging and replace the battery if necessary 

Consider changing your laptop battery if you discover that it is not charging while plugged in. This is an obvious indication that the battery is dead.

2. Constant Shutdown

The majority of modern computers are equipped with an automatic shutdown feature that prevents component damage. 


The majority of Windows 10 users are experiencing this problem more than Windows 7 and 10 users, despite interface improvements. Frequent shutdowns can also be caused by hardware breakdowns in addition to software issues. 


A shutdown may occur for causes other than hardware malfunctions, including as overheating, malware, driver problems, sleep mode settings, etc. 


However, it can be challenging for the user to identify the precise reason for the frequent shutdowns. Although overheating is the most frequent cause of computer shutdowns, malfunctioning batteries can also be the cause. 


When this occurs, the system will shut down as if the AC adapter had been disconnected from the power supply rather than as it would normally when a user shuts down from the Start menu. 

3. Overheating Laptop

A laptop may get hot while working on heavy tasks, but getting hot while working on little tasks is unusual. A battery issue could be the cause if you notice that your fans are whirling faster and that hot air is escaping. 


A lower capacity laptop battery will often overheat more than a higher capacity laptop battery. In addition to a malfunctioning battery, two other significant issues that might lead to a laptop overheating are clogged air vents and damaged fans. 


Thus, attempt cleaning the air vents and replacing the fans before concluding that the overheating is caused by a malfunctioning battery. It is obviously indicative of a dead battery if you continue to experience overheating.

4. Charging Issues

It will take a laptop battery in good condition 45 to 1 hour to charge completely. Mid- and older-generation laptops have problems with full discharge, even though many newer laptops can stop charging when the battery reaches 100%. 


 The lifespan of the laptop may be considerably shortened by fully draining or charging it above 100%. As a result, the laptop's charging process becomes much sluggish or may not occur at all. 


As a result, the user must always carry an AC adapter and look for a power outlet. The laptop will simply shut down if the user unplugs the AC adapter from the power source. 


There is a chance that the battery will only be backed up for 10 to 15 minutes if the charging proceeds more slowly to reach 100%.

5. Battery Age

There isn't a gadget in the world made to endure longer. Similar to other gadgets, a battery may eventually run out of power from prolonged use. 


When the user charges the laptop repeatedly, the battery's capacity to hold a charge may be decreasing. Most laptop batteries are typically covered by two-year maximum manufacturer warranties. 


For an improved experience, the manufacturers advise customers to replace the battery after this time. No matter how well you care for your laptop battery, eventually it will need to be replaced.
