Lenovo ThinkPad P50s Battery Pack Replacement

Difficulty

Easy

Steps

Time Required

15 - 30 minutes

Introduction

The internal battery allows you to use your Lenovo ThinkPad P50s laptop while not being plugged into an outlet. When the battery begins to drain quickly or has physical damage, you should replace it. This guide demonstrates how to replace the battery pack or internal battery. Some versions of the Lenovo ThinkPad P50s don't have an internal battery, there is just a "dummy battery."

Before you begin, disable the battery and remove the micro SIM card if your device has one. Make sure the laptop is off and disconnect the AC power adapter.

Safety measures should be taken before replacing the battery if it is swollen.

Tools

Step 1

Flip the device over so the bottom is facing you.

Step 2

How to slide the lock switch button outward--be more descriptive

Step 3

With your thumb slide the left lock switch button outward while sliding the battery out with your other hand.
When replacing the battery, make sure that the connectors are aligned properly.
You may hear a click when the battery is fully seated and the lock engages.

Step 4

Use a Phillips #00 screwdriver to unscrew the eight 2 mm captive screws.
These screws should not be removed entirely; you will be able to take off the base cover once they are loosened.

Step 5

With the plastic opening tool, pry up the base cover.
Slide the opening tool around the edge of the laptop to release the snap tabs.
You may need to use opening picks to hold the tabs apart, as the base is securely attached and tends to snap back into place.

Step 6

Lift the base cover off the laptop.

Step 7

With your fingers or a spudger, disconnect the battery cable from the motherboard.
Use the point of a spudger to push on alternating sides of the connector to "walk" it out of its socket.
It may take a lot of alternating before the connector comes out. Be patient, and don't pull on the cables.
To reconnect the cable, align the connector and use a spudger or clean fingernail to push it fully into the socket.
Don't push or pull on the cables themselves, or you may damage the connector.
