A broken hinge on a laptop is a problem faced by owners of devices of all brands: from budget Lenovo IdeaPad up to bonus MacBook Pro. The malfunction manifests itself in different ways: the screen may sag, creak when opening, or even fall off during operation. In 80% of cases, the cause is wear of the mechanism, but sometimes careless handling or manufacturing defects are to blame.
In this article you will find step by step instructions for repairing hinges without contacting a service center, including selecting tools, disassembling the case and installing new parts. We will also analyze when repairs are possible on your own, and when it is better to trust professionals - for example, if the matrix or display cable is damaged. For clarity, we present cost comparison table repairs in services and independently, and we will also give advice on preventing breakdowns.
Signs of a bad hinge: when it's time to act
The first symptoms of a hinge problem often go unnoticed until the laptop stops closing properly. Pay attention to the following signals:
- 🔊 Creaking or crunching when opening/closing the cover - a sign of bearing wear or dust getting into the mechanism.
- 📉 Screen sagging on one side - indicates a weakening of the fastening or deformation of the loop.
- 🚨 Spontaneous closing laptop - a dangerous symptom that can lead to damage to the matrix.
- 🔧 Tight opening covers - often caused by corrosion or deformation of metal elements.
If you notice any of these signs, don't put off repairs. For example, screen sagging by HP Pavilion or Dell Inspiron often leads to cable breakage, the cost of replacement is 3–5 times higher than repairing a loop. In some models (for example, MacBook Air M1) the hinges are integrated into the body, and their replacement requires complete disassembly of the device.
⚠️ Attention: If the laptop screen begins to “play” when touched (artifacts or flickering appear), stop using the device immediately. This is a sign of damage to the cable, and further operation may damage the matrix.

Repair tools: what you need
To repair laptop hinges yourself, prepare the following set of tools. Without them, you risk damaging the case or fastenings:
| Tool | Purpose | Where to buy | Cost, ₽ |
|---|---|---|---|
Screwdriver set PH00, PH0 |
For loosening case screws and hinges | AliExpress, "Chip and Dip" | 300–800 |
| Plastic paddles (pickers) | Release of case latches without scratches | Electronics stores | 100–300 |
| Tweezers with curved ends | Retains small screws and washers | Household goods, Leroy Merlin | 150–400 |
| Hot melt adhesive or epoxy resin | Fixing plastic elements (for cracks) | Construction stores | 200–500 |
| Multimeter | Checking the integrity of the loops (optional) | "Citylink", "M-video" | 1 000–3 000 |
For models with an aluminum body (e.g. MacBook or Huawei MateBook) additionally required special suction cup for removing the screen - it can be replaced with a regular glass suction cup. If you plan to replace the hinges completely, order spare parts in advance from AliExpress or in specialized stores (for example, Notik.ru). The cost of original hinges for Lenovo ThinkPad starts from 1,500 ₽, and for Asus ROG — from 2,500 ₽.
⚠️ Attention: Do not use metal spatulas or knives to disassemble the case - they leave scratches and may break the latches. Plastic picks are sold in sets of 5–10 pieces; choose ones with rounded edges.
Step-by-step instructions: how to remove hinges from a laptop
The disassembly process depends on the laptop model, but the general algorithm is the same for 90% of devices. We will look at a universal scheme using an example Acer Aspire 5 or HP 15:
Unplug the laptop and remove the battery (if removable)|
Take a photo of the location of the screws before unscrewing|
Prepare containers for small parts (such as bottle caps)|
Work on a soft surface (towel or antistatic mat) -->
- Removing the back cover:
Remove all screws on the bottom panel (usually marked with a
DorK). In models Lenovo Legion or MSI There may be hidden screws under the legs - carefully pry them up and check. Then use a plastic spatula to work around the perimeter, loosening the latches. Start in the corner near the hinge - there are usually fewer fasteners there. - Disconnecting cables:
After removing the cover, you will see the battery (if non-removable), the motherboard and cables going to the screen. Carefully remove them by pulling the plastic tabs (not the wires!). B MacBook the trains can be glued - use tweezers.
- Removing hinges:
The hinges are secured with 3–6 screws on each side. In some models (for example, Dell XPS) they are hidden under decorative plugs. On touchscreen laptops, the hinge may be part of the display frame, in which case a complete module replacement will be required. Unscrew the screws and carefully remove the hinge, remembering its position.
If the hinge does not come out, check for hidden fasteners. B Asus ZenBook Sometimes additional latches are used, which need to be pressed out with a screwdriver. After dismantling, inspect the hinge for cracks or play. If the mechanism is intact, but rotates slowly, it is enough to clean it from dust and lubricate it with silicone grease (for example, WD-40 Specialist).
Before disassembling the laptop Samsung or Xiaomi Check to see if it is still under warranty. These brands often void the warranty for do-it-yourself repairs, even if they do not involve a breakdown.
How to repair a hinge: 3 ways
Depending on the nature of the damage, you can restore the hinge using one of the following methods. The choice of method depends on the degree of damage and the laptop model:
1. Tightening the screws (for play)
If the screen sags, but the hinge is not broken, just tighten the mounting screws. Use a screwdriver PH0 and tighten the screws diagonally to avoid distortion. B MacBook Pro 2018–2020 screws may be under Pentalobe P5 - you will need a special bit for them.
2. Replacing bearings (for squeaking)
Squeaking hinges are often caused by worn plastic or metal bearings. Disassemble the hinge (it usually consists of 2-3 parts), clean the parts from old grease with acetone and apply new one. For Lenovo Yoga with convertible screen use Teflon grease - it does not attract dust.
3. Complete replacement of the hinge
If the hinge is cracked or deformed, it will need to be replaced. Buy a similar part (for example, for Asus TUF Gaming Loop with article number will fit 90NB0TY1-M02640). When installing a new hinge, make sure that:
- 🔧 The screws were tightened with force
0.3–0.5 Nm(use a torque screwdriver if available). - 📏 The loop was symmetrically located relative to the center of the screen.
- 🔌 The trains were not squeezed by the loop body.
In laptops Microsoft Surface The hinges are often attached to the magnesium frame - when replacing them, use original coated screws (usually black oxidized) to avoid corrosion.
What to do if the hinge breaks along with the mount on the body?
In this case, thread restoration will be required. For plastic housing use threaded inserts (For example, M2.5 for most laptops). For aluminum housing (as in MacBook) you can cut a new thread with a tap, but this requires precision. If the fastener breaks off completely, glue it with epoxy resin and reinforce it with fiberglass from the inside.
Common repair mistakes and how to avoid them
Even experienced users make mistakes that lead to additional breakdowns. Here are the most common of them:
- ❌ Using the wrong screwdrivers - for example,
PH1instead ofPH00. This strips the screw splines and they have to be drilled out. - ❌ Use of excessive force when the housing is separated. B Huawei MateBook D The plastic latches are fragile and break when pressed inaccurately.
- ❌ Forgetting to disconnect the battery before work. A short circuit can damage the motherboard (especially in MSI with tension
20V). - ❌ Incorrect assembly - for example, skewed hinges or forgotten screws. This leads to uneven pressure on the screen and matrix cracks.
To avoid these mistakes, follow the rule of "three checks":
- Check the suitability of the tools (size of bits, presence of plastic spatulas).
- Check that all cables and batteries are disconnected before working with the loops.
- Check the symmetry of the fasteners after assembly.
⚠️ Attention: In laptops Razer Blade The hinges are often attached to an aluminum frame, which bends under excessive force. If you feel resistance when removing the screws, stop and check to see if the threads are jammed.
The most common cause of broken hinges is careless opening of the laptop with one hand. Always hold the base of the device with your other hand to reduce stress on the mechanism.
Repair cost: comparison of independent and service
The price of hinge repair varies depending on the laptop model and the complexity of the work. The table below provides a comparative cost analysis:
| Laptop model | Cost of loops, ₽ | Cost of work in the service, ₽ | Total on your own, ₽ | Total in service, ₽ |
|---|---|---|---|---|
| Lenovo ThinkPad T480 | 1 200–1 800 | 1 500–2 500 | 1 200–1 800 | 2 700–4 300 |
| Asus ROG Strix G15 | 2 500–3 500 | 2 000–3 000 | 2 500–3 500 | 4 500–6 500 |
| MacBook Air M1 | 4 000–6 000 | 5 000–8 000 | 4 000–6 000 | 9 000–14 000 |
| Acer Swift 3 | 800–1 500 | 1 200–2 000 | 800–1 500 | 2 000–3 500 |
| HP Pavilion 15 | 900–1 600 | 1 300–2 200 | 900–1 600 | 2 200–3 800 |
As can be seen from the table, self-repair saves up to 50–70% cost, especially for premium models. However, consider the risks: if you damage the cable or matrix, the final cost of repairs may increase 2-3 times. For example, replacing the matrix for MacBook Pro 16" costs 30 000–50 000 ₽.
Service centers often offer “comprehensive repairs” including replacement of hinges and preventative cleaning. If your laptop is older than 3 years, this may be beneficial - e.g. Dell Latitude After 3–4 years of operation, the thermal paste needs to be replaced, which will extend the service life of the device.
Prevention: how to extend the life of laptop hinges
The service life of hinges depends not only on the quality of materials, but also on proper operation. Follow these tips to avoid breakdowns:
- 🖥️ Open your laptop with both hands - hold the base with one, lift the screen with the other. This reduces the load on the hinges by 2 times.
- 🧴 Lubricate hinges regularly (once every 6–12 months). Use silicone lubricant or
CRC 2-26. - 🚫 Do not place objects on the keyboard when the laptop is closed, this deforms the screen and increases the load on the hinges.
- 📦 Carry your laptop in a case with rigid inserts (for example, Thule or Amazon Basics).
- 🌡️ Avoid overheating — at high temperatures, the plastic elements of the hinges become brittle.
For laptops with touch screens (e.g. Microsoft Surface Pro or Lenovo Yoga) it is especially important to avoid sudden movements when transformed into a tablet. In these models, the hinges are often combined with a mechanism for fixing the angle of inclination, and their breakdown leads to unstable operation of the sensor.
If you often work on the road, consider purchasing laptop stands with adjustable tilt angle. This will reduce the load on the hinges during prolonged use. For example, stand Roost Stand distributes the weight of the screen evenly, increasing the service life of the mechanism by 30–40%.
FAQ: answers to frequently asked questions
Is it possible to fix the hinge without disassembling the laptop?
Partially yes. If the problem is play, you can tighten the hinge screws without removing the back cover (they are usually accessible from inside the case). However, disassembly is required to lubricate or replace bearings. In models with an all-metal body (for example, MacBook) you can’t do without disassembly.
How long does it take to replace a hinge?
For an experienced user - 1-2 hours, for a beginner - 3-5 hours (taking into account photographing the process and careful work). At the service center, repairs take 1–3 days, since the technician can simultaneously service several devices.
What should I do if the screen flickers after repair?
This is a sign of damage to the cable or incorrect connection. Immediately turn off your laptop and check:
- The tightness of the cable to the connector on the motherboard.
- Integrity of contacts (no bent or oxidized).
- Correct assembly (no pinched cables).
If the flickering remains, contact service - you may need to replace the cable (cost for Asus or Acer - about 1 500–3 000 ₽).
Which hinges are better - metal or plastic?
Metal hinges are more durable, but heavier and more expensive. They are installed in premium models (MacBook Pro, Dell XPS). Plastic hinges are lighter and cheaper, but wear out faster (service life is 3–5 years). In budget laptops (Acer Extensa, HP 250) combined hinges are often used: a metal frame with plastic bushings.
Can I use superglue to repair a broken hinge?
No, superglue is not suitable - it is fragile and cannot withstand dynamic loads. For plastic elements use epoxy resin (For example, Poxipol), and for metal ones - cold welding (Abro Steel). Before gluing, clean the surface of grease with acetone and leave the parts immobile for 24 hours.
