Laptop hinges are one of the most vulnerable structural elements that wear out, become loose or break over time. If your Lenovo ThinkPad, HP Pavilion or Asus ROG started to creak when opening, the screen sags or falls off completely, it’s time to think about replacing it. The service center will charge from 2 to 5 thousand rubles for this service, but if you have the tools and patience, you can do it yourself - save money and gain invaluable experience.
In this article we will analyze the entire process: from diagnosing the problem to the final assembly. You will learn how to select hinges based on your laptop model, what tools you will need, and how to avoid common mistakes, which lead to damage to the matrix or housing. We will pay special attention to the nuances for popular brands - Acer, Dell, MSI and others, where the design of the loops may differ radically.
Signs of hinge failure: when is it time to change
The first symptoms of hinge wear often go unnoticed until the problem becomes critical. Pay attention to the following signals:
- 🔊 Creaking or crunching when opening/closing the lid - a sign of abrasion of the lubricant or deformation of the metal.
- 📉 Screen sagging on one side when the laptop is on the table (especially noticeable on models with plastic hinges).
- 🚪 Tight opening or, conversely, the cover moves too freely (may indicate a breakdown of the spring mechanism).
- 💥 Visible cracks on or near the hinges - often found on laptops with an aluminum body (MacBook Pro, Huawei MateBook).
If these symptoms are ignored, over time the hinges may break completely, leading to damage to the matrix cable or even the screen falling onto the keyboard. For example, in models Dell XPS 13 And HP Spectre The thin hinges are integrated into the body, and replacing them requires care - a mistake can cost an expensive repair.
⚠️ Attention: If the screen starts to flicker or go dark when you change the angle, the problem may not be with the hinges, but with a damaged cable. In this case, first check the cable connection to the motherboard.
Which hinges are suitable for your laptop: how not to make a mistake with your choice
Laptop hinges are not universal - even one model may have different options depending on the year of manufacture. For example, loops for Lenovo IdeaPad 330-15 The 2018 and 2020 are similar in appearance but have different axle lengths and mountings. To avoid buying the wrong part, follow this algorithm:
- Check the exact model laptop (located on a sticker at the bottom or in
System Properties). - Look at the markings on old hinges (if they are still intact) - usually the part number is indicated there.
- Use directories spare parts:
- 🔧 eBay (filter by model + "hinge").
- 🛒 AliExpress (look for sellers with a rating above 98%).
- 🏢 Official dealers (for example, for Apple or MSI).
Pay attention to the material of the loops:
- Metal (steel, aluminum) - more durable, but heavier. Installed in gaming laptops (Asus TUF, MSI GF63).
- Plastic - lighter, but wear out faster. Often found in budget models (Acer Aspire 3, HP 250 G7).
| Brand | Model | Hinge type | Average price (pair) |
|---|---|---|---|
| Lenovo | ThinkPad T480 | Metal, with spring | 1 200 — 1 800 ₽ |
| HP | Pavilion 15-cs | Plastic + metal | 800 — 1 300 ₽ |
| Asus | ROG Strix G15 | Reinforced, steel | 1 500 — 2 500 ₽ |
| Dell | Inspiron 15 5000 | Aluminum, integrated | 1 800 — 2 200 ₽ |
⚠️ Attention: For laptops Apple MacBook (2015-2020) hinges are often sold complete with a top cover. Their replacement requires complete disassembly of the case and specialized tools (for example, iFixit Pro Tech Toolkit).

- HP
- Asus
- Dell
- Acer
- Apple
- Other
Replacement tools: what you need besides a screwdriver
To replace the hinges, you will need more than just a standard Phillips screwdriver. Many modern laptops (especially ultrabooks) are assembled using special screws with protection against self-repair. Here is the full list of tools:
- 🔧 Screwdriver set:
Phillips #00(for most screws).T5,T6(for MacBook and some Dell).Tri-wing Y0.8(for Nintendo Switch-similar fastenings in Asus).
- 🧲 Magnetic mat or a tray for screws (so as not to lose small parts).
- 🔨 Plastic picks (for neat removal of the lid).
- 🔥 Hair dryer or hot air station (if the hinges are glued, as in Microsoft Surface).
- 🛠️ Glue
B-7000orLoctite 401(for fixing new loops).
If you are working with a laptop where the screen is glued to the lid (for example, Xiaomi Mi Notebook), additionally prepare:
- Glue cutting thread (guitar string or special iFixit Opening Tool).
- Isopropyl alcohol (to clean up glue residue).
Before disassembling, take a photo of the location of all screws and stickers - this will help you reassemble the laptop correctly and not void the warranty (if it is still valid).
Step-by-step instructions: how to remove old hinges and install new ones
The process of replacing hinges can be divided into 4 stages: disassembly, dismantling old parts, installing new ones and assembly. Let's look at each step using a laptop as an example. Lenovo IdeaPad S340 (similar for most models with a removable back cover).
1. Disassembling the laptop
Unplug the laptop, remove the battery (if it is removable) and follow these steps:
Turn off power and remove battery|
Remove all stickers from the back cover (there may be screws underneath)|
Unscrew all the screws around the perimeter (usually 8–12 pieces)|
Carefully pry off the lid with a plastic pick, starting from the corner|
Disconnect the cables (if the cover is not completely removed) -->
In laptops HP Omen And Acer Predator the back cover can be glued around the perimeter. In this case, warm it up with a hairdryer (temperature 60–70°C) and carefully pry it with a string.
2. Dismantling old hinges
The hinges are usually attached to the case and screen cover with 3-4 screws on each side. In some models (for example, Dell Latitude) they can be additionally secured with latches. Remove them carefully, holding the screen so that it does not fall.
If the loops stuck or rusted, use penetrating lubricant WD-40 and let it sit for 10-15 minutes. Do not use excessive force as this may distort the seats.
3. Installation of new hinges
Before installation, check:
- Does it match axle length new loop with the old one (measure with a caliper).
- Is there spring mechanism (in some models it is built into the loop, in others it is a separate element).
Apply 1–2 drops of Loctite 401 glue on the screw threads - this will prevent them from unscrewing spontaneously. Tighten the screws criss-crossto avoid skew.
4. Assembly and testing
After installing the hinges:
1. Connect the matrix cable (make sure it is not kinked).
2. Close the lid and check the screen movement - it should open smoothly, without squeaks.
3. Turn on the laptop and make sure that the image does not flicker when changing the angle.
What should I do if the screen does not turn on after replacement?
If the screen remains black after assembly, check:
1. **Matrix cable** - it may not be fully inserted into the connector on the motherboard.
2. **Backlight** - bring the flashlight to the screen at an angle: if the image is barely visible, the problem is in the inverter or LED strip.
3. **BIOS** - sometimes after disassembly the settings are reset (click F2 or Del when loading and select Load Default Settings).
If all else fails, the cable may be damaged and will have to be replaced.
Common mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes when replacing hinges. Here are the most common ones and how to prevent them:
- 🔩 Tightening the Screws - leads to thread failure in the plastic case. Use a torque screwdriver with a force of no more than
0.5 Nm. - 🔌 Damage to the matrix cable - never bend it at an angle of more than 90°. In models Samsung Galaxy Book the train is especially fragile.
- 🧲 Lost screws — a magnetic mat or container with cells will help avoid this problem.
- 🔥 Overheating of the case with a hairdryer - Temperatures above 80°C may damage the plastic or battery. Keep the hair dryer at a distance of 10–15 cm.
Another common mistake is loop type mismatch. For example, in Asus ZenBook loops are used with left And right carving If you mix up the sides, the screen will open slowly or even jam.
⚠️ Attention: In laptops Microsoft Surface And Huawei MateBook X Pro hinges are often integrated into the screen module. Replacing them requires complete disassembly of the display, which without experience can damage the matrix. In such cases, it is better to contact the service.
If the hinges squeak after replacement, apply 1 drop of silicone grease to the axle (do not use WD-40 or lithol - they attract dust!).
How much does it cost to replace hinges at a service center vs on your own?
The cost of replacing hinges at a service center depends on the complexity of the work and the laptop model. On average prices are as follows:
| Laptop type | Cost of work (₽) | Cost of parts (₽) | Total |
|---|---|---|---|
| Budget (Acer Aspire, Lenovo V15) | 1 200 — 1 800 | 600 — 1 200 | 1 800 — 3 000 |
| Middle class (HP Pavilion, Dell Inspiron) | 1 500 — 2 500 | 1 000 — 1 800 | 2 500 — 4 300 |
| Premium/gaming (Asus ROG, MacBook Pro) | 3 000 — 6 000 | 2 000 — 4 000 | 5 000 — 10 000 |
| Ultrabook (Xiaomi Mi Air, Huawei MateBook) | 2 500 — 4 000 | 1 500 — 3 000 | 4 000 — 7 000 |
Self-replacement will only cost the cost of parts (from 600 ₽) and tools (if they don’t already exist). However, keep in mind risks:
- Damage to the matrix (price of a new one - from 5,000 ₽).
- Thread failure in the housing (replacement of the cover will be required).
- Loss of warranty (if the laptop is new).
If you have never disassembled laptops, practice on an old model or look video showdown exactly your model. For example, for Lenovo Legion And MSI GF65 There are detailed guides with notes about pitfalls.
FAQ: answers to frequently asked questions
Is it possible to replace only one hinge if only that one is broken?
Technically yes, but not recommended. The hinges wear out evenly, and if one breaks, the second will soon fail. In addition, new and old hinges may have different strokes, which will lead to screen skew. The exception is if the second loop is visually in perfect condition.
How do you know if the loops are the wrong size?
Signs of mismatch:
- The screws do not screw in completely or are loose.
- The screen opens with force or “sticks.”
- There are gaps between the cover and the body.
If you have already purchased the wrong hinges, check to see if they can be exchanged (for AliExpress Buyer protection is valid for 15 days).
What should I do if after replacing the hinge the screen begins to wobble?
Probable reasons:
1. Screws not tightened enough — check all fastenings with a torque screwdriver.
2. Wear of seats - if the holes in the plastic are loose, use larger diameter screws or epoxy glue.
3. Loop type mismatch - some models require loops with reverse thread (For example, Asus Vivobook).
How long does it take to replace hinges?
Time depends on experience and laptop model:
- Simple models (Lenovo V14, Acer Extensa) - 30–60 minutes.
- Medium difficulty (HP Envy, Dell XPS) - 1–2 hours.
- Complex (MacBook Pro, Razer Blade) - 3–5 hours (due to adhesive connections and fragile cables).
If this is your first time doing this, be patient and take your time - it's better to spend an extra hour than damage your laptop.
Is it possible to lubricate the hinges instead of replacing them?
Yes, but this is a temporary solution. Lubrication will help eliminate squeaking, but will not restore worn mechanisms. Use silicone grease (For example, Liqui Moly Silicon-Spray):
1. Remove the cover (as described above).
2. Apply 1-2 drops to the hinge shaft.
3. Open/close the screen several times to distribute the lubricant.
The effect lasts 3–6 months. If the hinges are already loose or cracked, lubricant will not help - they need to be replaced.
