How to Disassemble ONN Tablet: A Practical Guide
A comprehensive, safety-first guide for DIYers to disassemble an ONN tablet for repair or part replacement. Includes a complete tool list, step-by-step actions, reassembly tips, and safety precautions.
This guide shows you how to disassemble an ONN tablet safely and methodically, from powering down and removing the back cover to disconnecting the battery and accessing the motherboard. It outlines essential tools, safety precautions, and a clear step-by-step sequence to minimize damage and maximize chances of a successful repair or part replacement.
Safety First: Planning Your Teardown
According to Disasembl, the best teardown starts with a clear plan and a clean, static-free workspace. Before you touch a single screw, set aside a dedicated mat or tray for parts and small fasteners, and ensure you have good lighting. This reduces the risk of losing tiny components and makes reassembly easier. While ONN tablets are consumer devices, their internals use delicate cables and connectors that can be damaged by excessive force or misplacement. The goal is to minimize risk by moving methodically in stages rather than attempting a quick, brute-force pry. A careful plan also helps you avoid mixing fasteners or bending flex cables, which is a common cause of post-teardown failure. The Disasembl team stresses documenting every step, labeling screws, and keeping track of connectors to ensure nothing gets mixed up during the process. If you detect a swollen battery, stop immediately and consult a professional. Begin with a clean, well-lit workspace, a magnetic tray for screws, and a camera to record each step for later reference.
This approach is designed for DIY enthusiasts and homeowners who want a thorough teardown without damaging the device or voiding essential warranties. While the process may seem daunting, following a structured plan reduces risk and increases the likelihood of successful repair or part salvage. The Disasembl guidance emphasizes patience and precision over speed, so take your time and verify each connection before proceeding.

Tools & Materials
- Precision screwdriver set (PH0/PH1, Torx T5/T6)(Include multiple bits for small tablet screws)
- Plastic opening tools and spudgers(Avoid metal tools to prevent housing damage)
- ESD-safe wrist strap or grounding mat(Prevents electrostatic discharge)
- Nylon tweezers or non-metal pick(For handling tiny components and cable edges)
- Small parts tray or magnetic mat(Keeps screws organized by location)
- Isopropyl alcohol (90% or higher)(Cleaning contact surfaces and loosening adhesives)
- Soft brush and lint-free wipes(For dust removal and cleaning connectors)
- Anti-static mat or working surface(Helps maintain a static-free environment)
- Replacement battery or battery connector (optional)(Only if you intend to replace the battery)
- Camera or smartphone for step-by-step photos(Document connections and screw positions)
Steps
Estimated time: 60-120 minutes
- 1
Power down and unplug
Fully power off the tablet and unplug any charging cable or accessories. Remove any SIM/microSD trays if present and set the device aside on a non-scratch surface. This step reduces the risk of short circuits while you access internal components.
Tip: Double-check that the device is not charging and observe any residual power indicators before proceeding. - 2
Remove back cover screws
Use the appropriate precision screwdriver to remove all back panel screws. Keep track of screw lengths and positions by placing them in labeled sections of the tray. Do not mix screws from different locations as some fasteners secure delicate boards or shields.
Tip: Take photos of screw layouts before removing them to aid reassembly. - 3
Free the back cover
Gently pry around the edges with a plastic tool, working your way around the perimeter. If the back cover seems stuck, check for hidden clips or screws and apply light, consistent pressure rather than forcing the panel. Avoid touching the display area with metal tools to prevent damage.
Tip: Keep a steady, light touch and work slowly to prevent snapping clips. - 4
Disconnect the battery connector
Locate the battery connector on the motherboard and use a spudger to lift it from its socket. Disconnecting the battery first minimizes the risk of short circuits during component removal. If the connector is secured by a shield, remove the shield carefully before lifting the connector.
Tip: Work on a non-conductive surface and avoid bending any battery cables. - 5
Identify and disconnect internal cables
Label and photograph the arrangement of flex cables and connectors as you encounter them. Use a plastic pry tool to release connectors without applying lateral force. Remove shielding or boards only as needed to reach the next component, keeping track of where each piece belongs.
Tip: Label cables with tape and a marker to simplify later reassembly. - 6
Access the motherboard and storage
Once the primary cables are free, you can lift and remove the motherboard or memory modules as needed. Avoid bending flex cables and keep screws organized. If you remove the display assembly, disconnect the display cable with a light touch and verify the insulation on the connector is intact.
Tip: Handle memory components by edges; avoid touching gold contacts. - 7
Inspect for adhesives and adhesives management
Check around the frame for adhesive strips or thermal pads. Use isopropyl alcohol to loosen adhesive if necessary, but avoid soaking components. Keep adhesives organized so they can be reused or replaced correctly during reassembly.
Tip: Document adhesive locations to ensure clean reattachment later. - 8
Final checks and storage
Before replacing the back cover, verify that all cables are connected and that no tools remain inside the device. Place screws in a labeled container and review your photos to confirm nothing was left behind. Reassemble in reverse order when ready.
Tip: Do a final visual check for leader cables and ensure the screen seats properly.
Got Questions?
Is it safe to disassemble an ONN tablet at home?
With proper precautions and the right tools, a careful home teardown is possible. Always power down fully, disconnect the battery first, and work on a static-free surface. If you see swelling or damage, stop immediately and seek professional help.
Yes, but proceed with caution: power down, disconnect the battery, and stay on a static-free surface. Stop if you notice battery swelling or unusual heat.
Should I disconnect the battery before anything else?
Yes. Battery disconnecting reduces the risk of short circuits when you handle cables and boards. Do this before removing additional components or applying force to any connectors.
Yes—disconnect the battery first to minimize the risk of shorts when you work on the internals.
Will disassembling void the warranty?
Disassembly can affect warranty status depending on the manufacturer and warranty terms. If the device is still under warranty, contacting support first is wise; otherwise proceed only if you are comfortable with potential warranty implications.
Disassembly can affect warranty coverage. Check terms or contact support if the device is under warranty.
What tools do I absolutely need for this task?
A precision screwdriver set, plastic opening tools, an anti-static strap, and a small parts tray are essential. Additional items like Torx bits and isopropyl alcohol are helpful but not strictly required for basic disassembly.
A screwdriver set, plastic prying tools, an anti-static strap, and a tray for screws are essential.
