HP Pavilion 15-cc561st Battery Replacement

Introduction

Use this guide to replace the battery in a HP Pavilion 15-cc561st (product number 1KU29UA).

The 3-cell, 41-WHr, 3.6-AHr, Li-ion battery is rechargeable and provides power to the laptop when the laptop does not have an AC adapter plugged in.

A faulty battery will prevent the battery from holding power and properly charging, so a faulty battery should be replaced if you want to use your laptop portably. Read the troubleshooting page to figure out if your battery is faulty.

Removing the battery is also a required step for replacing every other component.

Shut down the laptop, disconnect all external devices, and unplug the AC adapter before beginning. Take the appropriate precautions if your battery is swollen.

Before you begin to remove the bottom cover, shut down the computer. Disconnect all external devices and unplug the AC adapter. Flip the laptop upside down.
Use a Phillips #0 screwdriver to remove five screws from the bottom cover:
Two 5.6 mm screws
Each of these screws are beneath the two rubber feet on the rear side of the laptop (near the display hinges). You do not have to completely remove the rubber feet to remove the screws; simply peel the top of the feet to reveal the screws.
Three 5.8 mm screws
Throughout this repair, keep track of each screw size and location to avoid damaging your device.

Insert an opening tool into the space between the display hinges and the bottom cover.

Use the opening tool again on the left and right sides.
Start prying at the areas closer to the rear of the laptop (near the display hinges) before moving towards areas that are closer to the front of the laptop (away from the display hinges).
Pry a little bit on the left side, then pry a little bit on the right side before prying more on the left side again. Working on both sides in this incremental fashion is easier than completely prying one side before starting the other side.
