Symptom(s):

• Device drops 
• Device doesn’t wake up computer after sleep
• Device is laggy 
• Delay when using the device

Likely Cause(s):

• Low battery levels
• Plugging the receiver into a USB hub or other unsupported device such as a KVM switch 
  NOTE: Your receiver must be plugged directly into your computer.
• Using your wireless keyboard on metal surfaces
• Radio frequency (RF) interference from other sources, such as wireless speakers, cell phones, and so on
• Windows USB port power settings
• Potential hardware issue (device, batteries or receiver)

Troubleshooting steps for:

• Wired devices
• Wireless devices: Unifying and non-Unifying devices
• Wireless devices: Bluetooth devices

Wired devices

1. Plug the device into a different USB port on your computer. If possible, don't use a USB hub or other similar device. If using a different USB port works, try updating the motherboard USB chipset driver.
2. Windows only — Disable USB Selective Suspend:
   • Click Start > Control Panel > Hardware and Sound > Power Options > Change Plan Settings > Change Advanced Power Settings > USB Settings > USB Selective Suspend Setting.
   • Change both settings to Disabled.
3. Update firmware if available. 
   
   • If you use G HUB: Launch the software, select the device from the home screen then go to Settings. If a firmware update is available, a Blue "Update" button would appear under the firmware version on the top right corner of the screen.
4. Try testing the device on a different computer.

Unifying and non-Unifying devices

1. Verify the product or receiver is connected directly to the computer and not to a hub, extender, switch or something similar.
2. Move the device closer to the USB receiver. If your receiver is in the back of your computer, it may help to relocate the receiver to a front port. In some cases the receiver signal gets blocked by the computer case, causing a delay. 
3. Keep other electrical wireless devices away from the USB receiver to avoid interference.
4. Unpair/repair or disconnect/reconnect hardware:
   • If you have a Unifying receiver, identified by this logo, see Unpair a mouse or keyboard from the Unifying receiver.
   • If your receiver is non-Unifying, it cannot be unpaired. However, if you have a replacement receiver, you can use the Connection Utility software to perform the pairing.
5. Update firmware if available. 
   
   • If you use G HUB: Launch the software, select the device from the home screen then go to Settings. If a firmware update is available, a Blue "Update" button would appear under the firmware version on the top right corner of the screen.
6. Windows only — check if there are any Windows updates running in the background that may cause the delay.
7. Mac only — check if there are any background updates that may cause the delay.
8. Try on a different computer.
