A laptop keyboard is more than just a set of buttons for entering text. It hides dozens of features that many users are not even aware of. From controlling screen brightness to launching Task Manager with one shortcut, knowing all the options saves time and simplifies your work. But how to understand this diversity, even if key layout different from the usual desktop keyboard?

In this article we will look in detail at how to use the keyboard on laptops under Windows, macOS And Linux, including rare features like function keys (F1-F12), multimedia buttons And touch panels with gestures. You will learn how to adjust the backlight, use Fn-combinations and avoid mistakes when working with the keyboard. And for those who are just mastering a laptop, we have prepared a unique table with all the hotkeys for popular brands (ASUS, Lenovo, HP, Dell).

1. Basic elements of a laptop keyboard: what is where

A laptop keyboard is smaller than a desktop keyboard, so some keys are combined or moved. For example, number pad (NumPad) is often integrated into the letter keys and is activated via Fn. A button Print Screen may be hidden under F11 or F12.

Let's look at the key areas:

  • 🔹 Function keys (F1-F12): control brightness, volume, power modes. On MacBook their role is played by the icon keys (🔆, 🔊, 🎵).
  • 🔹 Key Fn: Activates a second key function (for example, Fn + F5 may disable the touchpad).
  • 🔹 Arrows and NumPad: on small laptops (13-14 inches) the number pad is often missing or activated via Fn + MJKL.
  • 🔹 Multimedia buttons: play/pause, rewind buttons (may be on F-keys or separately).

On MacBook instead of Delete And Backspace one key (deletes the character on the left), and Command (⌘) replaces Ctrl in most combinations. On Windows laptops often there is a separate button Menu (calls up the context menu), which is not on Mac.

📊 What brand is your laptop?
  • ASUS
  • Lenovo
  • HP
  • Dell
  • Acer
  • Apple
  • Other

2. Hotkeys for Windows: complete list with examples

Hotkeys save time, but their combinations vary by manufacturer. For example, on Lenovo used to enable/disable the touchpad Fn + F6, and on HP — Fn + F9. Below are universal combinations for Windows 10/11:

Combination Action Usage example
Win + D Collapse all windows Quickly return to your desktop
Win + L Screen lock If you need to step away from your laptop
Alt + Tab Switch between windows Hold Alt for selection
Fn + arrows Brightness/Volume Control On some models Fn not needed
Win + PrtSc Screenshot Saves in Images → Screenshots

💡 Advice for gamers: on laptops with keyboards RGB (For example, ASUS ROG or MSI) the backlight is controlled via Fn + arrows or proprietary software (Aura Sync, SteelSeries Engine).

⚠️ Attention: On some laptops (eg. Dell XPS) key Fn blocked by default. To use F1-F12 as functional, click Fn + Esc.

3. MacBook Keyboard Features: What You Need to Know

Keyboards MacBook radically different from Windows-analogues. Not here Print Screen, and Option (⌥) And Command (⌘) replace Alt And Ctrl. Key combinations:

  • 🔹 ⌘ + C / ⌘ + V: copy/paste (as Ctrl + C/V on Windows).
  • 🔹 ⌘ + Space: challenge Spotlight (search by system).
  • 🔹 ⌘ + Tab: Switch between programs (analogue Alt + Tab).
  • 🔹 ⌥ + ⌘ + Esc: Force the program to close.

On new ones MacBook Pro (2021+) instead of physical Touch Bar Function keys have been returned, but on 2016–2020 models Touch Bar displays contextual buttons (brightness, volume, Siri). To capture its contents, go to System Preferences → Keyboard.

How to take a screenshot on MacBook?

On MacBook There are 3 types of screenshots:

1. ⌘ + Shift + 3 — the entire screen (saved to the desktop).

2. ⌘ + Shift + 4 — selected area (after clicking, select the area with the mouse).

3. ⌘ + Shift + 4 + Space — screenshot of the window (move the cursor over the window and click).

⚠️ Attention: If on MacBook the key doesn't work Eject (disc eject), use the combination ⌘ + E in Finder or drag the disc to the trash.

4. How to customize the keyboard backlight

Most modern laptops have keyboard backlighting (Lenovo Yoga, HP Spectre, MacBook Pro), but it is controlled differently. On Windows-devices are usually responsible for this:

  • 🔹 Fn + Space (enable/disable).
  • 🔹 Fn + up/down arrow (brightness adjustment).
  • 🔹 Branded software (ASUS Armoury Crate, Lenovo Vantage).

On MacBook The backlight turns on automatically in low light (light sensor next to the camera). To disable auto-adjustment:

  1. Go to System Preferences → Keyboard.
  2. Uncheck "Automatically adjust keyboard brightness".
  3. Use F5/F6 for manual settings.

Make sure that the laptop is connected to the network (on some models, the backlight only works from a power outlet)

Check the settings in BIOS/UEFI (on older laptops the backlight may be disabled there)

Update your keyboard drivers through Device Manager

Try resetting the BIOS (if the backlight stopped working after the update)

💡 Useful life hack: If the backlight flickers or is unstable, try cleaning the key contacts with compressed air - dust may interfere with the connection.

5. Troubleshooting: Keys not working, stuck or missing

What to do if the laptop keyboard doesn't respond on pressing or some keys stick? The reasons can be either software (drivers, viruses) or hardware (dust, mechanical damage).

Problem Possible reason Solution
Several keys do not work Contaminated or damaged membrane Cleaning the keyboard with alcohol or replacing the membrane
Keys stick Ingress of liquid or dust Drying (24+ hours) or replacing keys
Don't work Fn-combinations Driver disabled HotKey Update the driver via the manufacturer's website
Keyboard not detected Problem with the cable or controller Diagnostics at the service center

🔧 Keyboard cleaning instructions:

  1. Turn off your laptop and remove the battery (if possible).
  2. Turn the laptop upside down at a 45° angle and gently tap the back cover to release any large debris.
  3. Use a can of compressed air (keep at a distance of 5 cm).
  4. For sticky keys: remove the key (by carefully prying it up with a plastic spatula) and wipe the contacts with alcohol.
⚠️ Attention: Never use a vacuum cleaner to clean your keyboard - static electricity can damage electronic components. Also avoid liquid cleaners: they can stain the contacts.

6. How to use the touchpad with the keyboard

The touchpad (touchpad) on a laptop replaces the mouse, but many users are not aware of it multi-finger gestures. For example, on Windows:

  • 🔹 Two fingers up/down: Scroll the page.
  • 🔹 Three fingers left/right: Switch between windows.
  • 🔹 Four fingers up: opening Task bars.
  • 🔹 Double tap: analogous to double clicking the mouse.

On MacBook more advanced gestures:

  • 🔹 Four finger pinch: opening Launchpad.
  • 🔹 Four finger spread: show all desktops (Mission Control).
  • 🔹 Three finger tap: Search in the dictionary (if the word is highlighted).

🔧 Setting up gestures:

  • 🖥️ Windows: Settings → Devices → Touchpad.
  • 🍎 macOS: System Settings → Touchpad.
💡

If your touchpad is too sensitive, turn on the "Input Delay" option in Settings. This will prevent accidental touches while typing.

7. Hotkeys for specific tasks: from BIOS to virtual machines

Some key combinations are rarely needed, but in critical situations they save. For example:

  • 🔹 Entering BIOS/UEFI:
    • ASUS: F2 or Del.
    • Lenovo: F1 or Fn + F2.
    • HP: Esc → F10.
    • Dell: F12.
  • 🔹 Booting from a flash drive: usually F12, Esc or F9 (boot menu).
  • 🔹 Reset BIOS password: on some laptops (Lenovo ThinkPad) you can reset your password via Ctrl + Alt + Del when prompted for a password.
  • 🔹 Managing virtual machines:
    • Ctrl + Alt (left) - exit from full screen mode to VirtualBox.
    • Ctrl + Alt + Del in a virtual machine: Host + Del.

💡 For developers: on Linux useful combinations:

  • 🔹 Ctrl + Alt + F1-F7: Switch between terminals.
  • 🔹 Ctrl + Alt + T: open terminal (in Ubuntu, Mint).
  • 🔹 Super (Win) + D: Show desktop (like Windows).
💡

If the laptop does not respond to keys when booting, try connecting an external USB keyboard - this will help enter the BIOS or restore the system.

FAQ: Frequently asked questions about laptop keyboards

🔹 Why don't the keys work on my laptop? F1-F12 without Fn?

On some laptops (eg HP Pavilion or Dell Inspiron) keys F1-F12 By default they work as multimedia buttons. To return them to their default behavior, click Fn + Esc (called Lock Mode). Also check your BIOS settings (Function Key Behavior).

🔹 How to disable the touchpad if it interferes with typing?

The methods depend on the model:

  • 🖥️ Windows: Win + X → Device Manager → Mice and other pointing devices (disable touchpad).
  • 🖥️ Key combination: usually Fn + F6/F7/F9 (look for the touchpad icon on F-keys).
  • 🍎 MacBook: There is no hardware disable, but you can reduce the sensitivity in the settings.

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

Yes, but the complexity depends on the model:

  • 🔧 Mild cases: Lenovo ThinkPad, Dell Latitude — the keyboard is secured with latches; just disconnect the cable.
  • 🔧 Complex cases: MacBook, HP Spectre — the keyboard is soldered or requires complete disassembly.

📌 Important: Before replacing, check the compatibility of the keyboard (for example, for MacBook 2015-2019 Only original keyboards with a mechanism are suitable "butterfly", and for models 2020+ - "scissors").

🔹 How to turn on the number pad (NumPad) on a small laptop?

On laptops without a separate NumPad (For example, 13-14 inches) numbers are activated via Fn: 

Fn + MJKLUIO789 (правая часть клавиатуры)

Пример: "Fn + J" = 1, "Fn + K" = 2, "Fn + L" = 3.

On some models (ASUS ZenBook) you must first press Num Lock (usually Fn + F11).

🔹 Why does the keyboard print the wrong characters (for example, "th" instead of "q")?

This is due to the change keyboard layouts or input language. Solutions:

  • 🌍 Check your language in the taskbar (bottom right). Switch by combination Alt + Shift or Win + Space.
  • ⚙️ If the layout is wrong: Settings → Time and language → Language → Keyboard layout (remove unnecessary ones).
  • 🔄 On MacBook: ⌘ + Space to switch input source.

💡 If the problem persists, check your laptop for viruses - some Trojans change the layout.
