Laptop keyboards can stop working due to hardware damage, software glitches, moisture, dust, or connector issues. Understanding the cause helps determine the repair needed.

1. Physical Damage to the Keyboard

This is one of the most common reasons keyboards stop responding.

Signs:

• Broken, loose, or missing keys

• Keys that wobble or pop out

• Multiple keys stop responding after impact

Possible Causes:

• Dropping the laptop

• Pressure on the keyboard

• Kids or pets hitting keys

• Wear and tear on older keyboards

Repair Needed:Keyboard replacement or keycap replacement.

2. Dust, Dirt & Debris Blockages

NZ homes especially with pets, carpets, or coastal air often cause dust buildup inside laptops.

Symptoms:

• Some keys require extra pressure

• Sticky keys

• Random key failure

Dust can get underneath the membrane, blocking the key’s electrical connection.

Repair Needed:Deep internal cleaning + keyboard service.

3. Liquid or Moisture Damage

Even a small amount of liquid can damage keyboard circuits.This is extremely common in NZ due to:

• Coffee spills

• Water bottles leaking in bags

• Rain exposure

• Humid climate

Signs:

• Certain keys stop working

• Whole keyboard becomes unresponsive

• Keys type the wrong characters

• Laptop doesn’t detect the keyboard

Repair Needed:Liquid damage treatment + keyboard replacement if needed.

4. Faulty Keyboard Ribbon or Connector

Inside every laptop, the keyboard connects to the motherboard through a slim ribbon cable.If this cable is loose or damaged, the keyboard won’t work.

Symptoms:

• Keyboard works sometimes, then stops

• Only half of the keyboard works

• Keys randomly trigger

This is common after drops, DIY cleaning attempts, or manufacturing stress.

Repair Needed:Reconnect or replace the ribbon cable / connector.

5. Software, Driver or Windows Errors

Sometimes the keyboard is perfectly fine physically but software is causing the problem.

Symptoms:

• Keyboard stops working after a Windows update

• Keyboard types strange characters

• Delay when typing

• Caps Lock appears stuck on/off

Possible causes:

• Corrupted drivers

• Windows updates

• Malware

• Third-party software conflicts

Repair Needed:Driver update, software reset, malware removal.

6. Internal Hardware Failure (Motherboard Issue)

In rare cases, the keyboard circuit on the motherboard becomes damaged.

Signs:

• Keyboard AND touchpad stop working

• USB keyboard works fine

• Laptop shows internal connection error

This usually occurs because of liquid damage or power surges.

Repair Needed:Motherboard repair or IC-level repair (micro-soldering).
