Check the devices selected by the meeting app
A connected dock or headset can change the active microphone, speaker, or camera. Select each intended device in the app, play its speaker test, record and replay a short microphone sample, and check mute. Use the same dock, cables, and laptop power setup that you will use during the meeting.
Light the face and set the camera before upgrading it
Open the video preview at your normal meeting time. Move a bright window out of the background, put soft light near the camera, and adjust brightness until the face is clear without washing out detail. Bring the camera to a comfortable eye-level position. If you wear glasses, change the light's position and angle before adding brightness.
Choose one audio path to prevent echo
For one person in a shared or noisy room, a suitable headset can keep playback out of the microphone. For several people at one desk, test a speakerphone from every seat. Avoid joining nearby devices with both microphones and speakers active. Keep mute and volume within reach rather than solving feedback mid-call.
Test the actual connection and screen-sharing routine
Use the meeting service's test call from the desk. Check video, speech, and a sample screen share with ordinary background traffic. If calls break up, compare a practical wired connection or a stronger Wi-Fi location before replacing the camera. Prepare the files you will share and close private windows; confirm the app can share the intended screen.
Keep a usable fallback
Know how to reselect the built-in microphone and camera if a dock disconnects. Keep a charged headset or the meeting's permitted phone-audio option available when the call matters. Before joining, check framing, sound, mute, power, and the controls needed during the call.
