Step-by-Step Solution
Check the microphone is not muted
The Lenovo Smart Display has a physical microphone mute switch (on the side or back depending on the model). When muted, the Assistant cannot hear the wake word. Check the switch position — an orange or red indicator means muted. Flip the switch to unmute. The display should show a brief confirmation that the microphone is active.
Check WiFi and internet connection
Google Assistant requires an active internet connection. If the display shows 'Something went wrong' or does not respond: check your WiFi. In the display settings, go to Network > verify it is connected. If disconnected, reconnect to your WiFi network. The display supports 2.4GHz and 5GHz WiFi. Test by asking a simple question like 'Hey Google, what time is it.'
Restart the Smart Display
If the Assistant is unresponsive: hold the power button for 10 seconds until the display shuts off. Wait 10 seconds and press the power button to restart. After restarting (takes 1-2 minutes), try 'Hey Google' again. A restart clears temporary software states that cause the Assistant to stop responding. This is the quickest fix for most Assistant issues.
Check for software updates
Outdated software can cause Assistant malfunctions. Swipe down from the top of the display > Settings > System > About > System Updates. If an update is available, install it. Updates may take 10-15 minutes and require a restart. After updating, test the Assistant with a voice command. Google pushes regular updates that improve Assistant responsiveness and fix known bugs.
Retrain the voice model
If the display hears 'Hey Google' but responds to other household members and not you: the voice model may not recognize your voice. Open the Google Home app on your phone > Profile > Voice Match > retrain. Follow the prompts to say 'Hey Google' and 'OK Google' several times. This updates the voice model. If the display does not respond to anyone, the issue is not voice recognition but a microphone or software problem.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Set up geofencing so your system arms automatically when everyone leaves home and disarms when the first person returns. This eliminates the chance of forgetting to arm the system and provides seamless daily security.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
