How to Fix Laptop USB Ports Not Working
1. Restart Your Laptop
A temporary software glitch may cause USB ports not working on laptop problems.
Steps
- Save all work
- Shut down the laptop completely
- Wait 30 seconds
- Turn the laptop back on
- Test the USB port again
Why This Works
Restarting refreshes the USB controller and reloads Windows drivers.
2. Test Another USB Device
Sometimes the USB port is fine, but the connected device is faulty.
Test With:
- USB flash drive
- Mouse
- Keyboard
- External hard drive
- Android phone
- iPhone charging cable
For example:
- If your Xiaomi phone does not connect, try another phone
- If a flash drive fails, test a USB mouse
Why This Works
This helps determine whether the issue is the laptop or the USB device itself.
3. Try Another USB Port
If one USB port fails, another port may still work properly.
Steps
- Disconnect the USB device
- Plug it into another USB port
- Wait a few seconds
- Check if the device is detected
Why This Works
Different USB ports may use separate internal controllers.
This is one of the easiest fixes for USB ports stopped working issues.
4. Clean the USB Ports Carefully
Dust is a major reason for laptop USB ports not working.
Steps
- Turn off the laptop
- Disconnect the charger
- Use a flashlight to inspect the USB port
- Blow compressed air gently
- Use a soft brush carefully
Important
Do not insert metal objects into the USB port.
Why This Works
Dust blocks contact between the USB connector and internal pins.
5. Update USB Drivers
Outdated drivers often cause USB device not recognized errors.
Steps
- Press Windows + X
- Open Device Manager
- Expand Universal Serial Bus Controllers
- Right-click each USB device
- Select Update Driver
- Click Search automatically for drivers
Why This Works
Drivers allow Windows to communicate with USB hardware correctly.
6. Reinstall USB Controllers
Corrupted USB drivers can stop all USB ports from functioning.
Steps
- Open Device Manager
- Expand Universal Serial Bus Controllers
- Right-click each controller
- Select Uninstall device
- Restart the laptop
Windows will reinstall fresh USB drivers automatically.
Why This Works
This removes damaged driver settings causing laptop not detecting USB problems.
7. Disable USB Power Saving
Windows sometimes disables USB ports to save battery power.
Steps
- Open Device Manager
- Expand Universal Serial Bus Controllers
- Right-click USB Root Hub
- Select Properties
- Open Power Management
- Uncheck:
- “Allow the computer to turn off this device to save power”
- Click OK
Repeat for all USB Root Hubs.
Why This Works
This prevents Windows from automatically disabling USB ports.
8. Run Windows Troubleshooter
Windows includes built-in troubleshooting tools.
Steps
- Open Settings
- Go to System
- Select Troubleshoot
- Click Other troubleshooters
- Run the Hardware troubleshooter
Why This Works
Windows automatically checks for driver and hardware issues.
9. Update Windows
Missing updates can cause Windows laptop USB issues.
Steps
- Open Settings
- Go to Windows Update
- Click Check for updates
- Install available updates
- Restart your laptop
Why This Works

Sometimes USB ports are disabled inside BIOS settings.
Steps
- Restart the laptop
- Press BIOS key during startup:
- F2
- Delete
- Esc
- Find USB Configuration
- Ensure USB ports are enabled
- Save changes and exit
Why This Works
BIOS controls hardware settings before Windows starts.
11. Test USB Ports in Safe Mode
Safe Mode helps identify software conflicts.
Steps
- Press Windows + R
- Type:
msconfig - Open the Boot tab
- Enable Safe Boot
- Restart the laptop
- Test USB ports
Why This Works
If USB works in Safe Mode, another installed application may be causing the issue.

Physical damage can permanently affect USB ports.
Signs of Damage

- Bent USB pins
- Burn marks
- USB disconnecting repeatedly
- Ports not charging devices
What You Can Do
