Battery Calibration Misbehavior 

This problem usually occurs on old laptops with nonfunctional battery gauges, which results in a miscalculation of the amount of power plan that is left inside it.

This issue usually happens due to the fault of Microsoft Windows, which doesn’t automatically calibrate battery as new laptop users expect. For calibration purposes, you should charge your battery until it reaches 100% and then wait for about 10-15 minutes after disconnecting the adapter or remove your battery from Laptop and then put it back after 10-15 minutes.

If you don’t have enough time to do this, download third-party software for Battery calibration purposes.

Taskbar and Start Menu Settings 

In the Windows taskbar, by default, unnecessary programs are installed which eat up your computer memory and CPU usage.

These programs that reside in the taskbar eat up about 10% of your CPU usage and memory. They also affect the performance of other active programs as well as your laptop battery life.

To resolve this problem, you can either uninstall these applications or set their startup type to “disable.” This will prevent them from automatically starting whenever your Laptop is turned on and thus save memory usage and CPU usage.

Here is how to change the Startup type:

1- Right-click on Task manager and select Properties.

2- Click on the Start Menu tab, then click the “Customize” button.

3- On the next page, set all programs you don’t want to run automatically at startup to “disabled.”

4- Click on Ok and then click Apply.

Hardware Problem (Physical Damage) 

When you drop your Laptop, it may get some physical damage which can affect the power connector wire or connection between the AC adapter and Laptop.

If this happens, then there is a 100% chance that you will face battery draining issues.

Running Too Many Programs at a Time 

Many users think that running too many programs and opening dozens of browser windows is not considered as overworking your Laptop; however, this leads to physical damage when laptops components can’t handle the processing power required to run all these applications smoothly.

On the other hand, Overworking your laptop battery drains and creates overheating problems.

Several Apps Running in Background or Hibernate Mode

If you’re running several applications at the same time, these background apps will affect your Laptop’s performance and slow down your Laptop’s speed. This can also lead to overheating as well as draining battery life very quickly for a long period of time.

To stop unnecessary applications from running in the background and hibernating, you can use 3rd party software to close these processes and improve your Laptop’s performance and battery life.

Laptop Not Charging Properly 

If your Laptop doesn’t charge when plugged in, this may be due to the faulty AC power adapter or charging wire.

In this case, you can either replace your adapter or use an external charger for charging purposes.
