Mechanical or Magnetic Keyboard Disconnecting?

Troubleshooting Steps & Quick Fixes

📅Oct. 26. 2025

Few things are more frustrating than your keyboard suddenly disconnecting mid-game or while you’re typing an important message. Whether it’s caused by a loose cable, outdated firmware, or power-saving settings, most disconnection issues can be resolved with a few quick checks.

This guide walks you through why your magnetic switch or mechanical keyboard might be disconnecting — and how to fix it step by step.

Why Your Keyboard Keeps Disconnecting?

Keyboard disconnections usually stem from one of three main areas: physical connection issues, software or firmware errors, or wireless instability. Understanding which one applies to your situation helps narrow down the fix.

1. Physical Connection Issues

Loose or damaged cable – Over time, USB cables can loosen or fray, interrupting the connection.
Faulty USB hub or extender – Low-quality hubs can cause voltage drops, especially when multiple devices are connected.
Power fluctuations – On laptops or overloaded systems, insufficient USB power can cause temporary disconnects.

2. Software or Firmware Issues

Outdated drivers or firmware – Old firmware or missing USB drivers can lead to random connection drops.
System power management – Operating systems sometimes disable idle USB devices to save energy.
Corrupted configuration files – Custom keymaps or third-party drivers can occasionally cause handshake errors.

3. Wireless Connection Instability

Dongle interference – 2.4GHz receivers can be affected by nearby wireless devices.
Bluetooth pairing conflicts – Multiple paired devices or weak signal strength may cause frequent disconnects.
Low battery levels – Wireless keyboards may briefly lose connection when power is insufficient.
2.4G Receiver (USD Dongle) issues – In rare cases, the receiver itself may be unstable due to firmware or hardware faults. Updating the receiver firmware can help fix random disconnections.

How to Fix a Disconnecting Keyboard

Below are step-by-step fixes organized from simplest to more advanced, so you can follow them in order until the issue is resolved. However, please note that these may not necessarily fix the issue in all cases, and further consideration of the situation may be required.

Step 1: Check Physical Connections

Start by inspecting the basics.

For Wired Connection

Reconnect the USB cable firmly on both ends.
Try a different USB port, preferably on the back of your PC (directly to the motherboard).
Avoid using unpowered USB hubs or extension cables.
If you have a detachable cable, try another compatible one to rule out cable faults.

For Wired Connection

If your keyboard connects via 2.4GHz or Bluetooth, try these fixes:

Re-pair the dongle or Bluetooth device from scratch.
Move the receiver closer to reduce signal interference.
Replace or fully recharge the batteries.
Keep the dongle away from other wireless transmitters (routers, headsets, etc.), and make sure your receiver firmware is up to date if connection drops persist.

If your keyboard works fine after switching ports or cables, the issue was likely a physical connection.

Wireless instability often comes down to interference or power issues, both of which are easy to solve.

Step 2: Restart and Check Device Manager

Sometimes the system just needs a quick reset.

Restart your computerto clear any temporary driver or power conflicts.
On Windows:
Open Device Manager → Keyboards, right-click your keyboard, and select Update driver.
On macOS:
Try resetting the SMC and NVRAM to restore proper USB power control.
For other systems (like Linux or Chrome OS):
Please refer to their respective troubleshooting guides for managing device connections or updating input drivers.

If your system still fails to recognize the keyboard after these steps, proceed to other solution.

Step 3: Disable USB Power Saving Settings

Modern operating systems may suspend USB devices to save power — which can interrupt your keyboard connection.

On Windows:

Open Device Manager
Expand Universal Serial Bus controllers
Right-click each USB Root Hub → Properties → Power Management
Uncheck “Allow the computer to turn off this device to save power.”

On macOS:
Open System Settings → Battery → Power Adapter, then disable “Put hard disks to sleep when possible.”
On other systems (such as Linux or Chrome OS):
Refer to their respective power management settings or device control documentation to ensure USB devices are not automatically suspended.

Disabling USB power saving helps prevent the system from cutting keyboard power unexpectedly.

Step 4: Update Firmware or Software

This issue is most likely related to an uncommon or newly released system — especially those using AMD platforms — where the firmware may not be fully compatible with the system, leading to disconnection issues.

Check for firmware or software updates — Visit your keyboard’s official support page to see if a new firmware or software version is available. For firmware files, some brands only distribute them upon request to prevent users from flashing the wrong version and potentially bricking their keyboards. If you can’t find the firmware publicly available, contact customer support to get the correct version.
Follow official flashing instructions — Use the tool or method recommended for your keyboard model to safely flash the firmware. Avoid using firmware files meant for other devices.
Reconnect after update — Once the update completes, unplug and reconnect your keyboard to reset the connection handshake.

If the issue persists after updating, try testing the keyboard on another computer with a different configuration to verify whether it’s a firmware compatibility or system-specific problem. If the issue is resolved on the other system, it’s recommended to contact the customer support team for further assistance.

Step 5: Advanced Fixes and Checks

If your keyboard still disconnects after trying all basic and firmware fixes, it’s time to dig deeper into system-level or hardware-specific causes.

Inspect USB controller stability — Faulty motherboard USB controllers, especially on older boards or certain chipsets, can cause intermittent disconnects. Try switching to another USB port or a powered hub.
Monitor background software conflicts — Some third-party programs (e.g., RGB control tools, device managers, or antivirus suites) may override USB polling or device handling. Try disabling them temporarily to test stability.

How to Prevent Future Disconnects

Once your keyboard is working properly again, these habits can help avoid future issues:

Avoid pulling or twisting the USB cable when unplugging.
Keep firmware and drivers updated.
Clean USB ports periodically with compressed air.
Use quality cables rated for data transfer, not just charging.
Avoid placing heavy objects on the cable or connector area.

Consistent care can extend the life and stability of any mechanical keyboard.

A mechanical keyboard disconnecting issue doesn’t necessarily mean your keyboard is faulty.
In most cases, it’s a simple matter of a loose connection, outdated firmware, or overly aggressive power-saving settings. By methodically checking each cause, you can restore a stable and reliable connection in just a few minutes.

Since different keyboards may experience disconnection issues due to different causes, the most efficient approach is to contact the manufacturer for an official diagnosis and solution.
