Introduction

This guide shows how to replace the battery in the HP 15-ef1041nr laptop (HP 15-ef series) to restore proper power and portability. The battery supplies power when unplugged and may need replacement if the laptop won’t charge, drains quickly, or shuts down unexpectedly—see troubling shooting guide for confirmation. Before starting, power off and unplug the device, use ESD-safe practices, and disconnect the battery early to prevent damage. If the battery is swollen, handle it carefully and dispose of it at a proper e-waste facility.

Insert an iFixit opening tool into the seam betwen the keyboard area and bottom cover.
Using another iFixit opening tool, slide along the seam to unhook the clips.
There are clips all the way around the seam. You may hear a popping sound as the clips come loose. This step may require some force to separate the back cover from the laptop.
