Which way the ThinkPad camera slider is off

The ThinkPad camera slider is off when the shutter covers the webcam lens. Left versus right is a per-model bezel detail, so the supported check is the lens itself: hidden means the camera is off; visible means the camera can capture video. This guide does not include a model-by-model chart of slide direction, so confirm the covered position on the machine in front of you. Closing that shutter leaves microphone mute and speech-input selection on their own controls.

How to read the off position

The slider sits in the display bezel, usually above the screen. Move it until the opening over the camera is filled by the cover. In that position the glass is hidden and the webcam cannot capture video. Move it until the lens is visible in the opening and the camera can capture video. Some ThinkPad shutters show a colored patch when the lens is covered; use that as a helper and still verify that the glass is actually hidden.

• Covered lens: the camera is off.
• Visible lens: the camera can capture video.
• Black or unavailable preview in the Camera app or meeting software: the shutter is closed or the camera is otherwise disabled.
• Live image of you in the preview: the shutter is open.

If you recently used a different ThinkPad, treat this unit’s slider as its own layout. After you move the cover, open a camera preview so the off position is confirmed on this model.

Speech capture while the shutter is closed

The slider is a video privacy cover. Built-in microphones, headsets, and the recording device chosen in the operating system or meeting app keep their current state when the lens is hidden. To stop speech from being sent, mute the microphone in the conferencing app or with the notebook’s microphone-mute control, and watch the mute indicator. To keep talking with the camera covered, leave the microphone unmuted and choose the input you want for voice.

Audio input selection is independent of the shutter. Internal mics, dock audio, USB headsets, and Bluetooth headsets still appear as capture devices while the camera is covered. If colleagues hear you with the lens hidden, the microphone is open. If they cannot hear you with the lens visible, check mute, the selected input, and input level. Poor voice quality with the shutter closed is a mute, device-selection, or gain issue.

Limits of this answer

A single “slide left” or “slide right” rule would be a guess. Slide direction is mechanical and varies across ThinkPad lines, and the materials for this guide do not document each layout. Lenovo’s documentation for your exact model and the physical bezel on your unit settle left versus right. If the cover does not fully hide the lens, or the camera still produces an image while covered, treat that as a hardware or driver problem on that serial unit.

Supported next action: cover the lens to turn the webcam off, then set microphone mute and input in the meeting app so speech capture matches what you intend.
