Keyboard Not Working? Quick Fixes Before Professional Repair Malaysia

When Your Keyboard Stops Responding

You're in the middle of work, typing an important email, and suddenly half your keys stop working. Or maybe one key types multiple letters. Perhaps nothing responds at all.

Keyboard failures are among the most frustrating laptop problems because they immediately halt productivity. The good news? Many keyboard issues have simple fixes you can try before booking professional repair.

This guide covers troubleshooting for MacBook, Windows laptops, and Microsoft Surface devices, based on thousands of keyboard repairs we've completed at TechFix Malaysia.

Quick Diagnostic: Hardware vs. Software Issues

Before diving into fixes, determine if your problem is hardware or software related:

Software-Related Symptoms

• Keyboard works intermittently
• Works in BIOS/boot menu but not in Windows/macOS
• Certain keys work in some programs but not others
• On-screen keyboard works fine
• External keyboard works perfectly
• Problem started after software update

Likely cause: Driver issues, settings changes, software conflicts

Hardware-Related Symptoms

• Physical damage visible (spill, broken keys)
• Specific keys never work in any situation
• Keys feel mushy or stick down
• Multiple adjacent keys failed simultaneously
• Keyboard doesn't work even in BIOS
• External keyboard has same issues (suggests motherboard problem)

Likely cause: Physical damage, connection issues, component failure

MacBook Keyboard Troubleshooting

MacBook Butterfly Keyboard Issues (2015-2019 Models)

Apple's butterfly keyboard mechanism is notoriously problematic. If you have a MacBook from 2015-2019, you may qualify for Apple's keyboard service program.

Affected models:

• MacBook (Retina, 12-inch, Early 2015-2017)
• MacBook Air (Retina, 13-inch, 2018-2019)
• MacBook Pro (13-inch, 2016-2020 except M1)
• MacBook Pro (15-inch, 2016-2019)

Common butterfly keyboard problems:

• Letters or characters repeat unexpectedly
• Letters don't appear
• Key feels "sticky" or doesn't respond consistently

Fix 1: Compressed Air Cleaning (Apple's Official Method)

Apple recommends this for butterfly keyboards:

1. Hold MacBook at 75-degree angle (not flat)
2. Use compressed air to spray keyboard in left-to-right motion
3. Rotate MacBook to right side, spray left-to-right again
4. Repeat for all four sides
5. Focus on problem keys with short bursts

Why it works: Dust particles under butterfly mechanism prevent proper key registration. Compressed air can dislodge debris.

Success rate: ~30% for minor issues, 0% for liquid damage or mechanical failure.

Fix 2: Reset SMC (System Management Controller)

The SMC controls keyboard functionality among other hardware functions.

For MacBooks with T2 chip (2018-2020):

1. Shut down MacBook completely
2. Press and hold power button for 10 seconds
3. Release, wait 5 seconds
4. Press power button normally to start

For older MacBooks:

1. Shut down MacBook
2. Press Shift + Control + Option (left side) + Power button simultaneously
3. Hold 10 seconds
4. Release all keys, power on normally

Why it works: Resets hardware controllers that may be mismanaging keyboard input.

Success rate: ~15% for intermittent issues.

Fix 3: Reset NVRAM/PRAM

NVRAM stores keyboard layout and input settings.

1. Shut down MacBook
2. Power on and immediately press and hold: Option + Command + P + R
3. Hold for about 20 seconds (you'll hear startup chime twice on older models)
4. Release keys and let MacBook boot normally

Why it works: Clears corrupt keyboard configuration settings.

Success rate: ~10% for software-related issues.

Fix 4: Check Keyboard Settings

System Preferences issues to verify:

1. Go to System Preferences > Keyboard
2. Check "Key Repeat" isn't set to Off
3. Verify "Delay Until Repeat" isn't at maximum
4. Click "Modifier Keys" and ensure nothing is set to "No Action"
5. Check "Input Sources" shows correct keyboard layout

Accessibility settings to check:

1. System Preferences > Accessibility > Keyboard
2. Ensure "Slow Keys" is OFF (causes delayed key response)
3. Ensure "Sticky Keys" is OFF unless you need it
4. Check "Enable Mouse Keys" is OFF (can interfere with keyboard)

When MacBook Keyboard Needs Professional Repair

You need professional service if:

• Compressed air doesn't resolve issue after 2-3 attempts
• Multiple keys across different keyboard areas aren't working
• Keys are physically damaged or missing
• Liquid was spilled (even if dried)
• Keyboard worked then failed after heat exposure
• You have a 2016-2019 MacBook Pro with persistent issues

Professional repair options:

• MacBook keyboard replacement (RM450-850 depending on model)
• Butterfly keyboard conversion to Magic Keyboard (2020+ mechanism)
• Individual key cap replacement (RM80-150)

Windows Laptop Keyboard Troubleshooting

Fix 1: Restart Explorer.exe (Temporary Software Glitch)

Sometimes Windows Explorer conflicts affect keyboard input.

1. Press Ctrl + Shift + Esc (opens Task Manager)
2. Find "Windows Explorer" in process list
3. Right-click and select "Restart"
4. Test keyboard after Explorer reloads

Why it works: Refreshes Windows shell that handles input devices.

Success rate: ~20% for sudden keyboard failure without clear cause.

Fix 2: Update or Rollback Keyboard Drivers

To update drivers:

1. Press Windows + X, select "Device Manager"
2. Expand "Keyboards"
3. Right-click your keyboard device
4. Select "Update driver" > "Search automatically"
5. Restart laptop after installation

To rollback drivers (if problem started after update):

1. Device Manager > Keyboards > Right-click keyboard
2. Properties > Driver tab > "Roll Back Driver"
3. Follow prompts and restart

Why it works: Corrupted or incompatible drivers cause input failures.

Success rate: ~25% for issues that started after Windows updates.

Fix 3: Run Hardware Troubleshooter

Windows 10/11 includes built-in diagnostic tools.

1. Settings > Update & Security > Troubleshoot
2. Select "Additional troubleshooters"
3. Click "Keyboard" > "Run the troubleshooter"
4. Follow on-screen instructions
5. Restart if prompted

Why it works: Automatically detects and fixes common configuration issues.

Success rate: ~15% for software misconfigurations.

Fix 4: Check for Stuck Filter Keys

Filter Keys can make keyboard appear non-responsive.

1. Settings > Ease of Access > Keyboard
2. Ensure "Use Filter Keys" is OFF
3. Ensure "Use Sticky Keys" is OFF
4. Ensure "Use Toggle Keys" is OFF

Alternative method:

• Tap Shift key 5 times rapidly
• If a dialog appears, click "No" to disable Filter Keys

Why it works: These accessibility features alter keyboard behavior in ways that seem like malfunction.

Success rate: ~10% but quick to check.

Fix 5: Boot in Safe Mode Test

Safe mode loads minimal drivers, helping identify if third-party software is interfering.

1. Settings > Update & Security > Recovery
2. Under "Advanced startup" click "Restart now"
3. After restart: Troubleshoot > Advanced options > Startup Settings > Restart
4. Press 4 or F4 for Safe Mode
5. Test keyboard in Safe Mode

If keyboard works in Safe Mode:

• Problem is software-related (driver conflict, malware, startup program)
• Uninstall recently added programs
• Run antivirus scan

3. Click "Check for updates"
4. Install all Surface firmware updates
5. Restart when prompted

Why it works: Microsoft releases keyboard-specific firmware fixes for known Surface issues.

Success rate: ~20% especially for recently reported widespread issues.

Universal Keyboard Cleaning (Physical Maintenance)

Supplies Needed

• Compressed air canister
• Isopropyl alcohol (90% or higher)
• Cotton swabs
• Microfiber cloth
• Keycap puller (optional, for mechanical keyboards)

Cleaning Steps

For membrane keyboards (most laptops):

1. Power off laptop completely
2. Hold at 75-degree angle
3. Spray compressed air between keys (left to right pattern)
4. Rotate and repeat for all angles
5. Dampen cotton swab with isopropyl alcohol
6. Clean around keycaps gently
7. Wipe entire keyboard with lightly dampened microfiber cloth
8. Let air dry 10 minutes before powering on

NEVER DO THIS:

• Don't use household cleaners (leave residue)
• Don't pour liquid directly on keyboard
• Don't use vacuum cleaners (can create static discharge)
• Don't remove keycaps unless you're experienced (easy to break clips)

When DIY Won't Work: Signs You Need Professional Repair

Liquid Spill on Keyboard: Immediate Actions

If you just spilled liquid:

1. Immediately power off (don't shut down gracefully, hold power button)
2. Disconnect from power and remove battery (if removable)
3. Flip laptop upside down in tent position (so liquid drains away from motherboard)
4. Wipe visible liquid with absorbent cloth
5. Leave in tent position for 48 hours minimum
6. DO NOT use rice (doesn't work, leaves debris)
7. DO NOT use hair dryer (pushes liquid deeper into components)

After 48 hours:

❌ Don't just power on and hope

✅ Bring to professional for cleaning:

• Disassembly and inspection
• Ultrasonic cleaning of keyboard assembly
• Corrosion treatment
• Component-level testing

Why professional cleaning matters:

Even if keyboard seems to work after drying, sugar/minerals from drinks cause corrosion over days/weeks. This leads to:

• Gradual key failures
• Trackpad issues
• Motherboard short circuits (can total the laptop)

Cost comparison:

• Immediate professional cleaning: RM150-300
• Delayed motherboard replacement after corrosion: RM800-2000

Frequently Asked Questions

Can I replace just one keycap instead of the whole keyboard? Sometimes. For mechanical keyboards, yes (RM30-80 per key). For membrane keyboards like MacBooks, individual keycaps are RM80-150 but availability varies by model.

Why does my keyboard type multiple letters for one key press? "Key chattering" is caused by worn switch contacts (hardware) or driver issues (software). Try driver update first. If persists, needs keyboard replacement.

My laptop keyboard works but the backlight doesn't. Is this expensive to fix? Often it's just the backlight cable or LED strip, not the whole keyboard. Professional diagnosis can save money (RM150-300 repair vs. RM500-800 full replacement).

After spilling water, keyboard works but some keys feel sticky. Is it okay to keep using? No. Stickiness indicates residue that will corrode contacts. Get professional cleaning now before corrosion spreads to motherboard.

Can I use an external keyboard forever instead of fixing the built-in one? Yes, but it's inconvenient and reduces laptop resale value by 20-30%. Also, if the ribbon cable is loose, it might affect other components.

How long does keyboard replacement take? Most laptop keyboards: 1-2 days. MacBooks: 2-4 days (more complex disassembly). Rush service available for urgent cases.
