A broken laptop lid is not just an aesthetic problem, but a serious threat to the internal components of your device. Cracks in the case, especially around the hinges, can lead to distortion of the screen and damage to the backlight cable or the matrix itself. Many users immediately run to a service center, but in most cases, restoring the integrity of the plastic can be done independently, saving a significant amount of money.
The repair process depends on the type of damage: a crack along the edge, a broken corner, or a broken hinge mount. For models like HP Pavilion or Lenovo ThinkPad The approach may differ due to different body designs, but the general principles remain the same. The main thing is to act carefully and prepare the right materials for gluing or reinforcement.
Diagnosis of damage and assessment of the scale of the disaster
Before starting repairs, you must carefully inspect the device. Often the problem is not limited to a visible crack, but affects hidden layers of plastic or fasteners. Inspect the area of damage for chips where material has been completely lost, or deep fractures that cannot simply be glued together without reinforcement.
It is important to check the functionality of the hinges. If the lid is loose or the screen bends when closing, it means that the load is not distributed correctly, and simple gluing will not be enough. In such cases, replacement of plastic hinge bushings or even metal is often required.
Determine the housing material. Modern ASUS ZenBook often use aluminum alloys, while budget models ACER Aspire made of polycarbonate or ABS plastic. The choice of glue depends on this: epoxy for plastic may not take metal, and superglue will be brittle on flexible plastic.
Preparing tools and supplies
The success of the repair depends 90% on proper preparation. You will need a set of screwdrivers, preferably with magnetic bits, so as not to lose small screws inside the case. Be sure to purchase isopropyl alcohol to degrease surfaces before gluing - this is a critical step that is often ignored.
To restore plastic, it is best to use a two-component epoxy resin or a specialized plastic adhesive with an activator. If the crack is in a high stress area, you will also need metal staples, mesh, or even pieces of foil for reinforcement.

- 🧪 Two-component epoxy resin or glue for plastic
- 🏗 Metal mesh or foil for reinforcement
- 🧽 Isopropyl alcohol and cotton swabs
- 🔦 Powerful flashlight for inspecting hard-to-reach places
Don't forget about personal protective equipment. When working with chemical adhesives, use gloves and a respirator, especially if you plan to sand the hardened mixture with sandpaper.
⚠️ Attention: Never use Moment glue or cyanoacrylate compounds to repair areas with high mechanical load. They provide a rigid but extremely brittle connection that will crack again the first time the lid is opened.

- Screen damaged
- Scratches and scuffs
Methods for gluing plastic cracks
If the damage is minor and is a clean crack without loss of material mass, you can get by with classic gluing. Clean the broken area from dust and grease, then carefully apply glue. Do not try to fill the gap with an excess amount of compound - this will create internal stress.
To strengthen the seam, use the plastic “welding” method. Heat the edges of the crack with a soldering iron and carefully melt a thin wire or a piece of plastic taken from an invisible part of the case into them. This will create a monolithic structure that can withstand loads better than simply glued surfaces.
In the case of models Dell XPS or MacBookwhere the plastic has a complex texture, use plastic putty after gluing. It will allow you to level the surface before painting, making the repair almost invisible to the eye.
Remember that the polymerization time of the glue may differ from that indicated on the package. Do not rush to close the laptop and check its strength ahead of time. It’s better to wait an extra day than for everything to fall apart in an hour.
☑️ Preparation for gluing
Reinforcement and restoration of hinge fastenings
The most common problem is the broken part of the lid to which the hinge is attached. In this case, gluing is not enough, since the weight of the screen constantly pulls the fracture site down. It is necessary to create rigid reinforcement. A metal mesh or strips cut from a tin can are ideal for this.
Apply a coat of epoxy resin to the inside of the lid where the damage occurred. Place reinforcing material on top and saturate it with another layer of resin. It is important that the reinforcement covers the crack by at least 2-3 centimeters on each side.
If the plastic hinge bushing is completely destroyed, a new one will have to be made. You can use a brass bushing of a suitable diameter, gluing it into the prepared hole using epoxy. This will return the necessary rigidity to the hinge and prevent it from breaking again.
⚠️ Attention: When reinforcing metal inserts, make sure that they do not touch internal components such as Wi-Fi antennas or matrix cables, so as not to cause a short circuit.
Painting and finishing of the body
After the glue and reinforcement have completely hardened, the finishing stage begins. Sand off excess resin with 400 to 2000 grit sandpaper. Use a smooth, circular motion to avoid damaging the surrounding plastic.
If you used putty, let it dry and sand as well. Then degrease the surface and apply a primer. For plastic cases, acrylic primer in cans is best suited, which ensures good paint adhesion.
Apply paint in thin layers, allowing each to dry before the next. It is better to make 3-4 thin layers than one thick one, which will start to leak. Once the paint has dried, a clear coat can be applied to protect against scratches and provide a glossy or matte effect.

- 🛡 Primer for plastic
- 🌫 Transparent varnish (matte or glossy)
- 🧽 Masking tape to protect the screen
How to choose the exact paint color?
Find the color code on the sticker under the battery or in the instructions. If the sticker is lost, contact a specialized tinting studio, providing a sample of the plastic from the inside of the case.
Difficult cases: replacing the entire cover
Sometimes repairs turn out to be economically infeasible or technically impossible. If there are multiple cracks, the plastic is crumbling, or the screen itself is damaged, the only solution is to replace the top cover assembly. This is especially true for ultrabooks with thin bodies.
Replacing the cover requires completely disassembling the laptop. You need to disconnect the battery, unscrew all the screws, disconnect the keyboard, touchpad and display cables. Be extremely careful with fragile connectors that can easily break if handled carelessly.
After installing the new cover, reassemble the device in reverse order. Check the operation of all functions: keyboard, touchpad, webcam and, of course, opening and closing the screen. Make sure the hinges are tight enough.
Replacing the cover is a labor-intensive process that requires patience. If you are not confident in your abilities, it is better to entrust this work to professionals so as not to damage the motherboard or matrix.
| Type of damage | Recommended Method | Difficulty of repair | Approximate cost of materials |
|---|---|---|---|
| small crack | Epoxy gluing | Low | 100-300 rub. |
| Breaking the corner | Reinforcement + gluing | Average | 300-600 rub. |
| Breaking the loop | Bushing replacement + reinforcement | High | 500-1000 rub. |
| Multiple cracks | Replacing the cover assembly | Very high | 2000-5000 rub. |
⚠️ Attention: When ordering a new cover, be sure to check the laptop model and the case revision. Externally identical models HP 15-db0000 and HP 15-db1000 may have different mountings and sizes.
Repairing a laptop cover requires care and the correct selection of materials; reinforcement with metal mesh significantly increases the strength of the connection in areas of high load.
Prevention of repeated breakdowns
To avoid having to repeat repairs, change your device usage habits. Never open the lid by grasping one corner - this creates a distortion of the hinges. Always open your laptop by grasping the center of the lid or both sides at the same time.
Avoid transporting your laptop closed with foreign objects inside. Even a small pencil or flash drive caught in the gap between the keyboard and the screen can create a pressure point that will cause a crack when it closes.
Clean hinges regularly from dust. The accumulation of dirt increases friction and stress on the fasteners, which eventually leads to the destruction of the plastic. Use compressed air and a soft brush for gentle cleaning.
- 🚫 Do not open the lid by one edge
- 🧹 Clean hinges regularly from dust
- 🎒 Do not place heavy objects in your backpack on top of a closed laptop
- 🔌 Be careful with cables during transportation
Following these simple rules will extend the life of your device and save you from unnecessary repair costs. Remember that prevention is always cheaper and easier than recovery after a breakdown.
If you often carry your laptop in your backpack, use a hard case-holster. It will protect the case from deformation due to accidental pressure from other things.
What should I do if after gluing the lid is still loose?
Most likely, you did not provide sufficient reinforcement or the glue did not have time to fully polymerize. Disassemble the structure, add more metal mesh and increase the amount of epoxy resin. Make sure you follow the drying time specified by the adhesive manufacturer.
Is it possible to paint the laptop cover a different color?
Yes, it's possible. The main thing is to thoroughly sand the factory coating and use primer for plastic. Choose high-quality automotive enamel or special paint for plastic so that the color does not peel off after a month.
How to understand that a crack has affected the matrix?
If, when you press on the crack, stripes, spots appear on the screen, or the image disappears, it means that the cable or the matrix itself is damaged. In this case, repairing the cover must be combined with replacing the screen or re-soldering the cable.
Do I need to turn off my laptop before repairing?
Absolutely a must. Unplug the device, remove the battery (if it is removable) and press the power button for 10-15 seconds to discharge any residual voltage. This will protect the components from short circuits during removal.
