Have you turned on your laptop, but the cursor is frozen in place, and pressing the keys does not give any response? The situation is familiar to many - the device seems to be working (the indicators are on, the cooler is spinning), but it is impossible to control it. The reasons may lie either in a banal driver failure or in a serious hardware failure. In this article we will analyze all possible scenarios, from simple to complex, and we will give step by step instructions for every occasion.

It is important to understand: if the laptop does not respond to built-in keyboard And touchpad, but the external mouse works - this is the same algorithm of actions. If it refuses all connected equipment (including USB devices), the problem is deeper. We have structured the material so that you can quickly find a solution to your situation - from rebooting to disassembling the case.

1. Primary diagnosis: what to check first

Before you panic, do some basic checks. They will take no more than 5 minutes, but will help eliminate obvious causes.

  • 🔌 Check the connection of external devices: Disconnect all USB devices (flash drives, external HDDs, smartphones). Sometimes a hardware conflict blocks the keyboard and mouse from working.
  • 🔄 Force reboot your laptop: Press and hold the power button for 10-15 seconds. After switching on, check the response. If the problem disappears, it was a temporary OS failure.
  • 🖥️ Connect an external keyboard/mouse: If they work, the problem is with the built-in devices. If not, there is a system failure (drivers, BIOS, OS).
  • 🔋 Check battery charge: at a critical charge level (less than 5%) some laptops Lenovo, HP And Dell block input to save energy.

If the problem persists after rebooting, continue to the next section. Pay special attention to the point about BIOS - this is a critical point where many users make mistakes.

📊 How often do you have problems with the keyboard/mouse on your laptop?
  • Often (once a month or more often)
  • Sometimes (every six months)
  • Rarely (once a year or less)
  • Never happened

2. Software failures: drivers, conflicts, viruses

In 60% of cases the software is to blame. Let's look at typical scenarios and how to resolve them.

2.1. Keyboard/Mouse Driver Failure

Drivers can be lost after a Windows update, a program conflict, or a virus. To restore them:

  1. Connect an external keyboard/mouse (if they work).
  2. Click Win + X → select Device Manager.
  3. Expand branches Keyboards And Mice and other pointing devices.
  4. For each device:
    • 🔍 RMB → Update driver → Automatic search.
    • 🗑️ If it doesn’t help: RMB → Remove device → reboot the laptop (drivers will be installed automatically).

2.2. Program conflict or virus activity

Some programs (for example, AutoHotkey, KeyRemap, antiviruses like Kaspersky) can block input. Also, ransomware viruses sometimes disable the keyboard to protect their processes.

Start the laptop in Safe Mode (F8 on boot)

Open Task Manager (Ctrl+Shift+Esc) and end suspicious processes

Check system Malwarebytes or Dr.Web CureIt!

Remove recently installed programs via Control Panel → Programs and Features

-->

If in Safe Mode The keyboard/mouse works - the problem is definitely in the software. Try it restore the system to the point where everything worked:

  1. Click Win + R → enter rstrui → Enter.
  2. Select a restore point 2-3 days before the problem occurs.
What to do if there are no restore points?

If recovery is disabled, try resetting Windows to factory settings:

  1. Go to Settings → Update & Security → Recovery.
  2. Select Restore your computer to its original state (with saving files).
  3. After the reset, install the drivers from the official website of the laptop manufacturer.

3. Hardware faults: from contacts to microcircuits

If software methods do not help, the problem may be physical damage. Let's look at typical hardware causes and methods for diagnosing them.

3.1. Damage to keyboard/touchpad cables

Cables are thin ribbon cables that connect the keyboard and touchpad to the motherboard. They can move away from the connector (due to fall, vibration) or fray (in laptops older than 3–4 years).

  • 🛠️ How to check:
    • Gently press the area above the keyboard (closest to the screen). If contact appears, the cable has moved away.
    • Connect an external keyboard: if it works, but the built-in one doesn’t, the problem is in the cable or the keyboard itself.
  • 🔧 How to fix:
    • Disassemble the laptop (search for instructions for your model on YouTube by searching "laptop model disassembly").
    • Check the tightness of the cables to the connectors on the motherboard. If necessary, carefully insert them back.
    • If the cable is damaged, replace it (cost 300–1500 ₽ depending on the model).
💡

Before disassembling the laptop, take photographs of the location of all screws and cables. This will help you put it back together without unnecessary parts.

3.2. Problem with motherboard or USB controller

If they don't work all USB ports (including external mouse/keyboard) as well as built-in devices, the problem may be:

  • 🔌 South Bridge (chip on the motherboard responsible for USB, SATA, etc.).
  • 🔥 Burnt out capacitors (swollen or leaking).
  • ⚡ Short circuit after contact with liquid or power surge.

Diagnosing such problems requires special equipment (multimeter, programmer). If you are not an experienced repairman, it is better to contact a service center. The average cost of repairing a motherboard is from 3,000 to 15,000 rubles.

💡

If the laptop does not respond to external USB keyboard, but it boots - the problem is definitely in the hardware (motherboard, BIOS).

4. BIOS/UEFI failures: when the laptop “does not see” the input device

BIOS/UEFI is low-level software that controls the hardware before Windows boots. If the settings are wrong, the laptop may not “notice” the keyboard and mouse.

4.1. How to enter BIOS without a working keyboard

If your built-in keyboard doesn't respond and your external USB keyboard doesn't work either, try:

  • 🔌Connect PS/2 keyboard (via USB→PS/2 adapter). Older BIOSes recognize this connection better.
  • 🖥️ On some laptops (for example, ASUS ROG, MSI) there is a direct BIOS entry button on the rear panel.
  • 🔄 Remove the battery and power cord for 10 minutes - sometimes this resets the BIOS to default settings.

4.2. Reset BIOS and update firmware

If you were able to enter the BIOS:

  1. Find a section Load Default Settings (or Load Optimized Defaults) and apply the settings.
  2. Check if input devices are enabled:
    • Advanced → USB Configuration → USB Legacy Support [Enabled]
    • Advanced → Internal Pointing Device [Enabled]
  • Save changes (F10) and reboot.

    • If resetting doesn't help, try update BIOS:

    1. Download the latest BIOS from the manufacturer's website (for example, for Lenovo ThinkPad — here).
    2. Create a bootable USB flash drive with the BIOS (instructions are usually included with the firmware file).
    3. Update the BIOS through a special menu (usually launched by F12, Esc or another key during boot).
    ⚠️ Attention: Continuous BIOS update cannot be interrupted! If the laptop turns off during the process, the motherboard may fail.

    5. Features for different brands: Lenovo, HP, ASUS, Acer

    Each manufacturer has its own “diseases”. Let's look at typical problems and solutions for popular brands.

    Brand Typical problem Solution
    Lenovo (ThinkPad, IdeaPad) Touchpad failure after Windows update. Conflict with Synaptics or Elan drivers.
    1. Uninstall the touchpad driver via Device Manager.
    2. Install the driver from official website (not via Windows Update!).
    HP (Pavilion, Omen, EliteBook) The keyboard stops working after sleep/hibernation. The culprit is a function HP Sure View or HP Hotkey Support. Disable HP Hotkey Support in Startup (via Task Manager).
    ASUS (ROG, ZenBook, VivoBook) USB ports are disabled when multiple devices are connected. The problem is the USB controller's power limit.
    1. Enter BIOS.
    2. Find Advanced → USB Configuration → USB Power Delivery and install Enabled.
    Acer (Swift, Aspire, Predator) The keyboard only works in BIOS, not in Windows. Failure is often to blame ACPI-drivers.
    1. Boot into Safe Mode.
    2. Remove the driver ACPI in Device Manager (section System devices).
    3. Reboot - the driver will be installed automatically.

    If your model is not in the table, look for a solution using the query "laptop model keyboard/touchpad not working" on the forums Reddit or NotebookReview.

    6. What NOT to do during diagnosis

    Certain actions may make the problem worse. That's what absolutely not recommended:

    • 🔨 Disassemble a laptop without experience: risk of damaging cables or motherboard. If you are not sure, contact the service.
    • ⚡ Connect a keyboard/mouse to damaged USB ports: If the port sparks or wobbles, it can fry the controller.
    • 🔄 Reset BIOS via jumper (jumper on the motherboard) without instructions. Incorrect actions will lead to complete inoperability of the laptop.
    • 💾 Install drivers from dubious sources. Viruses in drivers can permanently damage input devices.
    ⚠️ Attention: If the laptop is under warranty, do not open it yourself! Most manufacturers (Apple, Dell, HP) will void the warranty if there are signs of tampering.

    7. Alternative ways to control your laptop

    If the keyboard and mouse do not work, but the laptop boots, you can control it using alternative methods.

    7.1. On-screen keyboard and voice input

    Windows has built-in tools:

    • 🖥️ On-screen keyboard: Start → Accessibility → On-screen keyboard (or click Win + Ctrl + O).
    • 🎤 Voice input: Settings → Accessibility → Speech → Enable speech recognition.
    • 🖱️ Keyboard cursor control: turn on Mouse with keyboard in Accessibility (arrow control).

    7.2. Remote control via smartphone

    If your laptop is connected to the same Wi-Fi network as your smartphone, you can control it through apps:

    • 📱 TeamViewer QuickSupport (for remote access).
    • 🖥️ Unified Remote (turns your smartphone into a remote control for your PC).
    • 🎮 Monect PC Remote (keyboard and mouse emulation).

    To do this, you need to first configure the application on your laptop (while the keyboard was still working) or ask for help from a friend who will connect to your PC remotely.
