So, let’s get started with any further discussion.

Why and When to Replace Your Dell Laptop Battery?

There are several reasons why your Dell laptop battery might need replacing:

  • Decreased performance: As batteries age, they lose their capacity to hold a charge, resulting in shorter runtime.
  • Bulging or swollen battery: This indicates a safety hazard and the battery needs immediate replacement.

  • Error messages: You might see error messages related to the battery health on your laptop screen.

Steps to Replace an Internal Dell Laptop Battery

Here are the steps to replace an internal Dell laptop battery:

Step 1: Turn off the laptop
