Did you accidentally spill coffee on your keyboard, or did it start to glitch after a Windows update? Perhaps you just want to replace it with a more convenient mechanical or RGB backlight. Anyway to buy exact replacement or a suitable alternative, you need to know keyboard model your laptop. But how can you recognize it if there are no obvious inscriptions on the case, and only general characteristics in the documentation?

In this article we will look at 7 Working Methods for Keyboard Identification - from simple inspection to the use of specialized utilities. You will learn where to look for hidden markings and how to decipher manufacturer codes (HP, Lenovo, Dell, Asus etc.), and why sometimes even the original replacement may not be suitable. And if you are planning a renovation, at the end of the article there is checklist by choosing a new keyboard.

1. Visual inspection: where to look for markings on the keyboard

The most obvious way is to carefully inspect the keyboard itself. Manufacturers often apply markings in inconspicuous places so as not to spoil the design. Where exactly to look?

  • 🔍 Back of the keyboard - turn the laptop over (turning it off!) and look at the bottom cover. Sometimes the code is located next to the keyboard mounts or under the battery.
  • 🖼️ Under the keys — carefully pry the key with your fingernail or plastic card F1, Esc or Space (they are the easiest to remove). Under them there may be a sticker with the article number.
  • 📏 On the train - if you are ready to disassemble the laptop, disconnect the keyboard cable: it is often indicated on it part number (For example, DA0KU5MB8F0 for Asus).

The marking is usually a combination of letters and numbers, for example:

  • Lenovo: 00HN536, 5B10H13695
  • HP: 715659-001, L36320-001
  • Dell: 0F932H, CN-0F932H
⚠️ Attention: Not all keyboards have visible markings! If you haven’t found the code, don’t despair, move on to the following methods. Also be careful when removing the keys: the plastic latches are easy to break.
📊 What brand is your laptop?
  • Lenovo
  • HP
  • Dell
  • Asus
  • Acer
  • Apple
  • Other

2. Using programs to determine the model

If the physical examination is unsuccessful, the software will help. There are utilities that read component data directly from the system. Here are the most reliable:

  • 💻 AIDA64 - in the section Devices → Keyboard displays the model (for example, AT Translated Set 2 keyboard for standard or HID Keyboard Device for USB-connected).
  • 🔧 HWiNFO — shows detailed information about connected input devices, including vendor ID And product ID.
  • 🖱️ Device Manager (Windows Device Manager) - open Keyboards, right-click on the device → Properties → Details → Hardware ID. There will be lines like ACPI\PNP0303 or HID\VID_046D&PID_C52B.

Transcript example Equipment ID:

Code in Device Manager What does it mean Manufacturer example
ACPI\PNP0303 Standard PS/2 keyboard (built-in) Any laptop
HID\VID_046D&PID_C52B USB keyboard from Logitech (VID = Vendor ID) Logitech, external devices
USB\VID_8087&PID_0A2B Built-in keyboard Intel (often in Dell or HP) Intel, Dell, HP

If the utilities display only general information (for example, “Standard PS/2 keyboard”), this means that the system does not recognize the specific model. In this case, move on to the next method.

💡

If in Device Manager the keyboard shows up as "Unknown device", try updating your drivers via Update configuration or download them from the laptop manufacturer's website.

3. Search by laptop model: databases and catalogs

Each laptop has a unique model and serial number, which you can use to find a compatible keyboard. Where to look?

  • 📄 Sticker on the bottom of the laptop - look for lines like Model: 81D2 (y Lenovo), P/N: X5E45UA (y HP) or Type: 20L6 (y Dell).
  • 🔍 Official websites of manufacturers — enter the laptop model into the search on the site Lenovo, HP Support or Dell Parts. For example, for Lenovo ThinkPad T480 the keyboard may have an article number 01AX764.
  • 🛒 Spare parts catalogs - services like AliExpress, eBay or NotebookCenter allow you to filter keyboards by laptop model. Use keywords: "keyboard for [your model]".

Example search query for Asus ROG Strix G531:

Asus ROG Strix G531 keyboard replacement part number

Asus G531 клавиатура оригинал артикул

⚠️ Attention: The same laptop may have different keyboards depending on sales region or model revisions (For example, HP Pavilion 15-cs3000 And 15-cs3000tx - different keyboards!). Always check exact modification.

Specify the model and revision of the laptop (for example, Acer Aspire 5 A515-51G vs A515-51)

Check the number of keys and their location (especially Fn, NumPad, Power)

Check the connection type (loop or USB)

Make sure it is compatible with your OS (some keyboards require special drivers)

4. Disassembling a laptop: how to get to hidden markings

If other methods do not work, you will have to partially disassemble the laptop. This is an extreme, but sometimes the only way. How to do this safely?

  1. Turn off your laptop and disconnect the battery (if it is removable).
  2. Remove the bottom cover - it is usually secured with screws under rubber feet or rivets. Use a plastic pick to avoid scratching the body.
  3. Find your keyboard — it is screwed to the top panel or secured with latches. The train is usually located closer to the center.
  4. Disconnect the cable — carefully lift the latch (black or white plastic tab) and pull out the tape.

You will find markings on the back of the keyboard or on the cable. For example:

  • U HP EliteBook 840 G5 — L51840-001.
  • U Dell Latitude E5470 — 0F932H CN-0F932H.
  • U MacBook Pro 2017 — 661-00145 (for butterfly keyboard).
⚠️ Attention: By disassembling your laptop, you risk losing your warranty! If the device is under warranty, contact the service center. Also be careful with cables: they can be easily damaged by static electricity.
What to do if the keyboard is soldered?

Some ultrabooks (eg. MacBook Air or Dell XPS 13) have keyboards soldered to the motherboard. In this case, replacement is possible only at a service center using a soldering station. Self-repair may result in failure of the entire board!

5. Definition from photographs: services and communities

If you are not sure about the marking or have not found it at all, you can use a visual search. Here's how it works:

  • 📷 Take a photo of the keyboard above and below (if there is access). Make sure that key locations, logos, and any writing are visible.
  • 🌍 Upload photos to services:
    • Google Lens or Yandex.Pictures - can find similar images.
    • Reddit (r/thinkpad, r/Dell, r/laptops) - ask a question with a photo and description of the laptop model.
    • Forums like NotebookReview or 4PDA — they often discuss the compatibility of spare parts.

Example of a request on the forum:

Подскажите модель клавиатуры для Acer Swift 3 SF314-56-5872!

Фото: [вставьте ссылку на изображение]


Особенности: нет NumPad, подсветка белая, клавиша Power справа вверху.

Often users share part numbers or even sell used keyboards. The main thing is to indicate the most accurate details: number of keys, availability NumPad, backlight color, location Fn.

💡

Even if you find a visually identical keyboard, check the cable compatibility! Some models (eg Lenovo Legion) have the same design, but different connection connectors.

6. Contacting the service center: when it is justified

If all the previous methods did not help, or you are afraid of damaging the laptop during disassembly, the best option is to turn to professionals. When is this necessary?

  • 🔧 Laptop under warranty — Replacing the keyboard yourself will void the warranty.
  • 💻 Complex design - for example, at MacBook with a butterfly keyboard or ultrabooks Dell XPS with soldered components.
  • 🔍 No time to search — service centers have access to manufacturers’ databases and can quickly select spare parts.

How much does it cost?

Service Cost (approx.) Deadlines
Keyboard diagnostics 500–1500 ₽ 15–30 minutes
Keyboard replacement (without spare parts cost) 1500–4000 ₽ 1–3 hours
Cleaning the keyboard after a spill 2000–5000 ₽ 1–2 days

Before visiting the service center:

  1. Check to see if they work with your brand of laptop (some service centers specialize only in Apple or Lenovo).
  2. Ask if they provide original or replacement parts.
  3. Ask about the warranty on the work (usually 1-3 months).

7. Alternative solutions: if the original keyboard is not available

Sometimes it is impossible to find an original keyboard - for example, for old laptop models or rare brands. In such cases, consider alternatives:

  • 🔄 Universal keyboards - suitable for most 15.6-inch laptops (for example, from Perixx or Targus). They connect via USB, but occupy a port and require drivers.
  • 🖥️ External keyboard - mechanical or membrane models with backlight (for example, Keychron K3 for compactness).
  • 🔧 Repairing a current keyboard - if the problem is flooding, you can clean the contacts with isopropyl alcohol (but this is a temporary solution).
  • 📱 On-screen keyboard - on Windows, click Win + Ctrl + Oto enable the virtual keyboard (suitable for temporary use).

When choosing a universal keyboard, pay attention to:

  • Size - must correspond to the diagonal of the laptop (13", 15.6", 17").
  • Connection type - USB or Bluetooth (the second option frees up the port, but requires charging).
  • Availability Fn-keys - some programs (for example, Photoshop) actively use them.
💡

Before purchasing a universal keyboard, check reviews for compatibility with your OS. Some models do not work correctly with Linux or macOS.

FAQ: Frequently asked questions about laptop keyboards

Is it possible to replace the keyboard on a laptop yourself?

Yes, if the keyboard is connected via a cable (and not soldered). To do this you will need: a screwdriver, a plastic pick, tweezers and a new keyboard. The main thing is not to damage the cable when disconnecting. For most models Lenovo, HP And Asus There are detailed guides on YouTube.

How to find out if a keyboard is original on AliExpress?

Original keyboards on AliExpress are rare. To reduce your risk, check:

  • Seller rating (98% and above).
  • Photos of the actual product (not stock pictures).
  • Reviews with photos - compare the markings on buyers’ keyboards with yours.
  • Price - the original cannot cost 2-3 times cheaper than from official suppliers.

Most often on AliExpress They sell high-quality replicas that fit the connector, but may differ in key material or backlighting.

Why doesn't the new keyboard work after replacement?

Possible reasons:

  • Unsuitable cable - check if the number of contacts matches.
  • The connector on the motherboard is damaged - inspect it for oxidation or broken contacts.
  • Drivers are missing - for some keyboards (e.g. RGB backlight) you need proprietary utilities (Lenovo Vantage, Dell SupportAssist).
  • Incorrect connection - the cable must be inserted until the latch clicks.

If the keyboard still does not work, try connecting an external one via USB - if it is not detected, the problem is in the motherboard.

Is it possible to change the keyboard on a laptop to a mechanical one?

Technically yes, but it is difficult and not always justified. Mechanical keyboards are thicker than membrane keyboards, therefore:

  • Modification of the housing (milling of holes) will be required.
  • You need to connect via USB or solder the controller.
  • The weight and thickness of the laptop will increase.

There are ready-made solutions for some models (for example, Framework Laptop supports replaceable modules), but for most laptops this is a custom project. An alternative is an external mechanical keyboard (for example, Keychron K2).

How to clean a laptop keyboard if it gets stuck?

If the keys become sticky due to dust or spilled liquid:

  1. Turn off the laptop and disconnect the battery.
  2. Turn the laptop over and shake it lightly to release any crumbs.
  3. Use a can of compressed air (keep at a distance of 10 cm).
  4. For sticky keys: soak a cotton swab in isopropyl alcohol (90%+) and gently wipe the contacts under the keys.
  5. If the liquid gets deep, disassemble the keyboard and rinse the board with distilled water, then dry it for 24 hours.
Don't use: wet wipes, soapy water or vacuum cleaner (may damage membranes).
