Introdução

Use this guide to replace the power button board and the interconnect cable in your Kobo Libra Colour (model N428B) eReader.

Important: There are two Libra Colour versions: N428 and N428B. Check your eReader's model number (printed on the edge of the device with the USB‑C port) before starting this guide. This guide is for the N428B model.

If your power button isn't working, but all other functions are working properly, you may need to replace the power button

Following this guide will remove your eReader's IP (Ingress Protection) rating, making it susceptible to water damage.

Kobo supports their eReaders with a warranty. If your device is still under warranty, Kobo may be able to help. Before starting a repair, review your warranty information or check support documentation.

    • Drain your eReader's battery as much as possible before starting your repair. Ideally, it should be fully discharged.

    • Optionally, to drain the battery faster, navigate to More → Settings → Energy saving and privacy and set Automatically go to sleep after and Automatically power off after to Never.

    • When working on or near the battery, don't use sharp metal tools to avoid puncturing and shorting the battery.

    • Unplug all cables and fully shut down your eReader.

    • Your screen should be black and say Powered off.

    Don't forget to remove the protective sheet from the replacement screen (as I did). Thanks for the manual, its working now again!

    Haha I second that! I nearly had a heart attack when I realized I hadn't removed the plastic film

    • Flip your eReader over so the screen is facing down.

    • Angle an opening pick straight down, and insert its tip under the top right corner of the back cover, near the power button.

    • Push downward and pry up with the pick until you feel it slide between one of the clips and the frame.

    • You may have to test a few spots along the corner until the pick slides between one of the clips.

    • Slide the pick toward the bottom right corner to release the clips along the right edge.

    • Angle the pick flat under the back cover and rotate it around the bottom right corner to release its clips.

    • If you're having trouble, try twisting the pick to lift the corner clips out of their slots.

    • At this point, you should be able to grip the back cover and release its remaining clips. If not, slide a pick under the perimeter of the back cover until you can grip an edge.

    • Grip the right edge of the back cover and lift it away from the eReader to release the remaining clips.

    • Remove the back cover.

    • During reassembly, align the back cover over the eReader and press along the perimeter until all its clips snap back into place.

    • The entire surface of the eReader's internals is covered in a thin, plastic-like waterproof coating. Keep the following in mind as you continue disassembly:

    • While this won't hurt your device, removing the coating compromises the device to potential water damage.

    • The coating is brittle and can flake into many small pieces. Heating the coating helps, but working with it is still a time-consuming process.

    • Depending on your repair, you might have to remove the coating from ZIF connectors and their cables.

    • Use a spudger to pry up and disconnect the battery press connector.

    • Don't pry against the motherboard, as you risk breaking small, surface-mounted components.

    • Your E-ink screen will continue to say Powered off even after disconnection—this is normal!

    • Heat an iOpener and lay it on the power button ZIF connector (near the top right corner of the motherboard) for 90 seconds to soften the coating.

    • Alternatively, you can use a hair dryer or heat gun for 30 seconds to soften the coating.

    • Use the tip of a spudger and pointed tweezers to scrape and remove the coating from the ZIF connector's locking tab and cable.

    • If the coating becomes too brittle and hard to peel off, reheat the power button board and try again.

    • This is a meticulous process! Failure to remove enough of the coating could damage the locking tab during disconnection, so take your time!

    • Use the tip of a spudger to lift up the locking tab on the power button ZIF connector.

    • The locking tab should be nearly vertical when unlocked. If not, remove more coating until the tab can move freely.

    • Use angled tweezers to push the cable fully out of its socket, pushing on the small "arms" near the head of the cable.

    • If you're having trouble, you can use your fingers to gently pull on the cable—don't grip the cable with tweezers or you may damage it.

    • The power button and its cable are adhered to the frame.

    • Lay a heated iOpener on the power button and its cable for 90 seconds to soften the adhesive.

    • Alternatively, you can use a hair dryer or heat gun for 30 seconds to heat the power button and its cable.

    • Carefully slide an opening pick under the cable and power button to separate the adhesive.

    • Work slowly to avoid creasing or folding the cable, and apply more heat if the cable or button feel stuck.

    • Remove the power button.

    • During reassembly:

    • Use a spudger to remove any remnants of the power button adhesive from the frame.

    • Use high‑concentration (>90%) isopropyl alcohol and a lint‑free cloth (or coffee filters) to clean up any adhesive residue.

    • If your power button comes with adhesive pre‑installed, remove the liners. If it doesn't, apply thin, double‑sided tape to the frame where the old adhesive was.

    • Align the power button's cutouts with their pegs on the frame and push the button into place to secure it.

    • Don't secure the cable with adhesive just yet. Wait until after you've reconnected the cable to ensure it will reach the socket.

Conclusão

To reassemble your device, follow these instructions in reverse order.

Remember: after repairs, your eReader is no longer IPX8 waterproof.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.

Make sure each of your device's main functions still work, e.g., LED backlight, touch, page-turn buttons, Wi-Fi, etc.

Take your e-waste to an R2 or e-Stewards certified recycler.
