HP Envy x360 15m-bq021dx Power Input Replacement

Difficulty

Moderate

Steps

Time Required

1 - 2 hours

Introduction

If your HP Envy x360 15m-bq021dx (also known as HP Envy x360 Convertible 15m series) is not charging or only charges intermittently, the power input jack may be damaged or faulty. This guide will show you how to safely replace the power input port to restore the normal charging function.

The power input jack connects your device to an external power source, allowing the battery to charge and the laptop to operate while plugged in. A failing jack may cause your device to lose power, not charge the battery, or only charge when the connector is positioned at a certain angle.

Important Safety Tips:

Completely power off your device and unplug it from all power sources before beginning the repair.
Use ESD-safe tools and an anti-static wrist strap to avoid damaging internal components.
If your battery is swollen or shows signs of damage, follow this guide on what to do with a swollen battery before continuing.

This guide does not require soldering but involves carefully removing several components to access the power jack. Take extra care when disconnecting ribbon cables and handling internal parts.

Tools

Step 1

On the back panel of the device, remove the four (4) M2.5xL6 screws at the top of the photo using a Phillips #0 screwdriver.
Unscrew the three (3) screws at the bottom of the photo using a T5 Torx screwdriver.

In the second step the photo looks like the laptop is still in the same position as the first step, which means, according to the first image, the second image shows someone removing the four screws at the top of the laptop. To be accurate to the text in Step 2, the barcode would appear at the top of the image.

Step 2

To remove the back cover, use the black spudger to lift up on the edges of the cover.
Use a suction cup to assist in lifting the back cover

Step 3

Use the Philips #0 screwdriver to remove six (6) M2.0x3.2 screws from battery.

There are 7 red highlight circles showing on the image.

Okay, I see the seventh screw is addressed in the next step, #4. Shouldn’t the image in Step 3 show just the six screws the instructions is referring to>

Step 4

Using the Philips #0 screwdriver, remove the final screw from the battery connected to the SSD storage unit.

Why is this seventh screw separate from the other six in the prior step?

Step 5

Lift and pull the front of the battery up and out (away from the connector) to remove.

Step 6

Using a Philips #0 screwdriver, remove the three M2x4 screws located around the cooling fan as shown in this picture.
Be careful as the fan might be sharp in some places when removing it.

Step 7

Remove the connector clip with the tweezers.

The fan connector on the one I was working on was in a different location, below the fan near the battery connector

Step 8

Remove the four spring loaded screws with a Philips #1 screwdriver.

Step 9

Remove the cooling fan.

Step 10

Using a Phillips #1, remove the seven M2.0x3.2 screws.
Undo the six connections using the blue opening tool.

There’s a few errors/omissions here. There is no screw where the red circle notes on the bottom right, it is actually top left and not circled in red. There is also a connector on the top right that needs to be disconnected just to the right of the LCD connector highlighted in the orange box. Finally, I needed to disconnect the wifi cables and remove the screw affixing the card to the case in order to remove the board (the wifi card connects to a slot beneath the board, rather stupidly).

The connector on the top right mentioned in my previous post is for the speakers
