In this guide, we'll walk you through the process of disassembling the case, so you can replace a broken glass, re-solder a cable, or simply clean out dust. It's important to understand that accuracy At every stage, we guarantee a successful repair without compromising the electronics' functionality. We'll cover all the details of opening the back cover, disconnecting cables, and accessing the motherboard.
Before you begin physically manipulating the device, you need to prepare your work area. The light should be bright, and the table should be clear of unnecessary objects to prevent small screws from getting lost. It's also worth making sure you have all the necessary tools on hand, as interrupting the process mid-way can lead to oxidized contacts or the loss of small parts.
⚠️ Attention: Any tampering with the device's casing automatically voids the manufacturer's warranty. If your tablet is still under warranty, it's best to contact an authorized service center.
The main difficulty when working with budget models often lies in the mounting design. Unlike flagship devices, which use complex screws and adhesive frames, these often use standard latches. However, the plastic can be brittle, and excessive force when opening the case will cause cracks in the case, ruining the appearance of the assembled device.
Necessary tools and work area preparation
Good preparation is half the success of any repair. For disassembly 4good t101i You'll need a minimal but specific set of tools to avoid damaging the case and internal components. Using unsuitable tools, such as knives or thick needles, is strictly not recommended, as they can damage cables or puncture the battery.
First of all, get a set of precision screwdrivers. Most often, these tablets use screws with caps like Phillips Small Phillips-head screwdrivers. A plastic spudger or pick for opening the case is also highly recommended. Metal tools should be used with extreme caution only where there is no risk of damaging electronics.
- 🔧 A set of Phillips-head screwdrivers (PH00, PH0) for unscrewing screws.
- 🛑 A plastic spatula or an old bank card to open the latches.
- 🔥 A hair dryer or heating pad to soften the glue (if the screen is glued).
- 🧲 Magnetic mat or container for sorting screws.
Organization is also important. It's recommended to use a magnetic mat or simply lay down a light-colored cloth to make small screws more visible. If possible, use tweezers with curved tips—they'll help you gently pry up cables and remove small components from hard-to-reach places.
⚠️ Attention: Before starting work, be sure to discharge the tablet's battery to 15-20%. Working with a fully charged battery increases the risk of fire or swelling in the event of an accidental short circuit when disconnecting the contacts.
Don't forget about lighting. Shadows from your hands or tools shouldn't fall on the work area. Good lighting will allow you to see the smallest fastening details and spot hidden screws under stickers or caps. A magnifying glass or desk lamp will make the process much easier.
☑️ Checking readiness for repair
Turn off the power and remove the back cover
The first and most important step is to completely power down the device. Although the tablet can be powered down by software, residual voltage still remains on the motherboard. 4good t101i This is critically important, as accidentally shorting the contacts while the battery is connected can damage the power controller.
Start with a visual inspection of the device's perimeter. Run your finger along the joint between the front and back panels to identify any screws. On some models, screws may be hidden under decorative caps or rubber feet. Carefully inspect the area around the camera and ports—fasteners are often hidden there.
Removing the back cover requires patience and even pressure. Don't try to force the cover in one spot, as this will break the plastic latches. Move around the perimeter, gradually releasing the clips with a plastic card or spudger. A distinctive click will indicate the release of each latch.
- 🔍 Carefully inspect the ends for hidden screws under the stickers.
- 🖐️ Warm the edges of the case with a hair dryer on low temperature if the plastic is too hard.
- 📏 Move the spatula along the seam, without inserting it deeper than 5 mm.
- 👂 Listen to the clicks - they will tell you where it is already open and where it is still holding.
Once all the latches around the perimeter are released, don't rush to open the cover. There may be ribbon cables inside that connect the buttons or antennas to the main board. Lift the cover a few millimeters and look inside to ensure there are no loose connections.
What to do if the lid does not open?
If you're sure all the screws are removed, but the cover won't budge, there may be a hidden screw hidden under the warranty sticker or in the stylus hole. The plastic may also have deformed from heat, causing the latches to stick. In this case, gently using a suction cup to lift the edge will help.
Access to internal components and battery
Once the back cover is successfully removed, the internal structure of the tablet will be revealed to you. 4good t101iThe motherboard is usually located at the top or bottom of the case, and the battery takes up most of the space. First, disconnect the battery cable from the motherboard.
The battery connector is usually a white plastic connector with wires attached. Don't pull on the wires, as this will break them. Use a spudger or your fingernail to gently pry the connector upward. On some models, the connector may be secured with a metal clip that needs to be bent back first.
If you're replacing the battery, remove the old battery after disconnecting the ribbon cable. It may be attached to the case with double-sided tape. To remove it, you can use a plastic card, carefully sliding it under the battery. Avoid using metal objects to avoid puncturing the battery casing.
| Component | Location | Mounting type | Peculiarities |
|---|---|---|---|
| Battery | Central part | Glue/Scotch tape | Be careful with punctures |
| Motherboard | Top/Bottom of the case | Screws + latches | Lots of small trails |
| Speaker | Body angle | Glue/Grooves | Thin wires |
| Camera | In the corner of the board | Adhesive tape | Fragile lens |
When working with internal components, pay attention to markings. trainsThey are very thin and easily torn if handled carelessly. If you need to remove a speaker or camera, first disconnect their connectors from the board and then carefully remove them from their mounting locations.
Removing the motherboard and screen module
The most difficult stage of disassembly 4good t101i Access to the motherboard and screen is essential. The board is often covered by an additional metal shield that protects the processor and memory chips from electromagnetic interference. This shield is held in place by numerous small screws that must be removed in a specific sequence.
Before removing the board, be sure to photograph the locations of all the cables. This will help you reconnect them correctly during reassembly. The display and touchscreen cables are usually the widest and located closest to the edge of the board. They are secured in their connectors using clamps that need to be folded upward.
Removing the screen if it's glued to the frame will require heat. Use a hair dryer to heat the perimeter of the display. This will soften the adhesive, allowing you to carefully separate the module from the frame. Be extremely careful: the display glass is very fragile, and the touchscreen is sensitive to pressure.
- 📸 Take a photo of all connections before disconnecting.
- 🔩 Unscrew the screws of the metal screen counterclockwise.
- 🌡️ Heat the glue with a hair dryer to a temperature of 60-70 degrees.
- 🧤 Use a suction cup to lift the display after heating.
After disconnecting all cables and removing all screws, the motherboard should slide freely out of the case. Check to see if any antenna wires or button cables are caught. It's best to handle the board by the edges, avoiding touching the contacts and microchips with your fingers, as static electricity can damage sensitive electronics.
⚠️ Attention: The display and touchscreen cables have very thin conductive tracks. Even a microscopic tear or break can cause streaks on the screen or complete failure of the touchscreen.
If you're replacing just the screen, after removing the old module, degrease the frame of the new one with alcohol before gluing it on. Use special B-7000 adhesive or double-sided tape for electronics. Apply the adhesive evenly around the perimeter and press firmly until the module is completely dry.
Replacing the charging connector and other modules
One of the most common reasons for disassembling budget tablets is the breakage of the micro-USB or USB-C connector. In the model 4good t101i This connector can be soldered directly to the motherboard or connected via a small ribbon cable adapter. The connection type can only be determined after removing the protective metal shield.
If the connector is on a ribbon cable, replacing it is simple: simply unscrew the retaining bracket, remove the old ribbon cable, and insert the new one. If the connector is soldered to the board, soldering equipment and IC soldering skills will be required. In this case, if you're inexperienced, it's best to contact a professional, as there's a risk of overheating the board and damaging adjacent components.
Camera modules are also frequently replaced. They are attached with adhesive or slotted into place. When installing a new camera, make sure the lens is clean and the cable is securely fastened to the connector. Don't forget to remove the protective film from the lens before final assembly.
Tablet speakers are usually not repairable, only replaceable. They may be glued or simply inserted into plastic guides. When installing a new speaker, check the polarity of the connection, although modern connectors often have protection against reverse connection.
Assembling the device and initial launch
Assembling the tablet 4good t101i Reassembly is performed in the reverse order of disassembly. This is the golden rule of electronics repair.
