Introduction

Follow this guide to replace a dead or malfunctioning battery in your Asus ROG Ally.

Lithium-ion batteries have a limited lifespan. If your device doesn't hold a charge or dies unexpectedly, it might be time to replace the battery.

Let your device's battery drain below 25% before starting this repair—a charged lithium‑ion battery may catch fire if damaged.
Completely power off your device and unplug all cables.
Consider laying your device on a soft cloth to prevent scratching or damaging the screen during your repair.

Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from.
Use a Phillips #0 screwdriver to remove the five 17.2 mm‑long screws securing the top edge and bottom corners of the back cover.
Use a Phillips #0 screwdriver to fully loosen the remaining captive screw at the center of the bottom edge. This should create a small gap between the back cover and chassis.
Don't try to remove this screw.

Insert the flat edge of an opening pick between the bottom edge of the back cover and chassis, near the captive screw.
Angle the pick upward and push it under the back cover.

Plastic clips secure the perimeter of the back cover. You should feel and hear them release during this step.
Slide the opening pick along the bottom edge and around the corners of the back cover to release the clips securing it.
Keep the pick at an upward angle under the back cover to help release the clips.

Lift the bottom edge of the back cover off the chassis to release the remaining clips.
Remove the back cover.
During reassembly, lay the back cover onto your device and firmly push down around the perimeter to engage the clips.

Use your fingers to peel up and remove the black plastic cover between the fans.
Put the cover aside—you'll use it during reassembly.

A metal locking bar secures the top edge of the battery connector
Use the flat end of a spudger to gently push the locking bar away from the connector to unlatch it.

Make sure the locking bar is not covering the battery connector at all, or you may damage the socket and the locking bar.
Insert the flat end of a spudger under the center of the battery connector.
Lift the connector straight up and out of its socket to disconnect the battery.
During reassembly, use your fingers or the flat end of a spudger to firmly push the connector onto its socket until it clicks into place.

Use a Phillips #00 screwdriver to remove the four screws securing the battery:
Two 9.6 mm‑long screws near the center of the top edge
The screw near the left speaker has a warning sticker on it. Pierce through it with your screwdriver or use tweezers to remove it.
Two 3.4 mm‑long screws at the left and right edges

With one hand, hold the ribbon cable that runs along the top of the battery out of the way.
With your free hand, lift the battery straight up and remove it.

If your replacement battery doesn't come with a cable installed, follow this step to remove and transfer the old one.
With one hand, firmly secure the outer battery cells.
With your free hand, use the point of a spudger to push on alternating sides of the battery connector to walk it out of its socket.
To install the cable:
Gently push the connector partially into its socket.
Use a spudger to push in the outer edges of the connector until it slides fully into its socket.
Do not push on the cables themselves, as this can easily damage them.
