Hi everyone, welcome back to DIYGeardo.

In this guide, we’ll show you how to replace the power button and volume button flex cable on the Apple iPad 9th Generation (10.2-inch, 2021). If your iPad’s power button is not responding, volume buttons are stuck, or buttons work intermittently, a faulty flex cable is usually the cause.

The power and volume buttons on the iPad 9 are integrated into a single flex cable assembly, mounted along the frame. Replacing this part requires screen removal and careful handling of internal components, but it can fully restore button functionality when done correctly.

Before starting, make sure you have the correct replacement flex and proper repair tools, which you can find in the description. This guide is suitable for DIY repairers and technicians, and we’ll walk you through each step clearly.
