Direct answer
For the Lenovo IdeaPad Slim 5 family, privacy permission, physical shutter/mute, one app, device selection and hardware should be separated. First, test the built-in camera/recorder outside the call app.
What this covers
- Lenovo IdeaPad Slim 5 family (Confirm machine type/model on bottom label)
- Lenovo PC; machine type/model determines BIOS, dock, ports, drivers and warranty configuration.
- The specific fault this record addresses: camera or microphone is not working in calls
What it does not cover
- ×The same symptom on a different Lenovo product line, which has its own record and its own cited source
- ×An on-screen error code whose meaning has not been checked against this exact model's manual
- ×Live electrical, gas, sealed-system, internal battery-cell or structural repair — a technician boundary, not a self-service step
Differential
What actually causes this, and how to tell them apart
These are ordered by how often each one is the answer, not by how easy it is to try. The point of the middle column is that two causes producing the same headline symptom rarely produce the same detail — that detail is what tells you which one you have before you change anything.
- 1
The application does not have permission
What separates it A black camera preview or no microphone input in one application, while others work.
How to confirm Both macOS and Windows gate camera and microphone access per application, and the prompt is easy to dismiss. Check the privacy settings for that specific application.
- 2
Another application is holding the camera
What separates it The camera is unavailable or in use, with another conferencing application running in the background.
How to confirm Only one application can use the camera at a time on most systems. Quit the others completely rather than just closing their windows.
- 3
A privacy shutter or hardware switch is closed
What separates it A black image with the camera otherwise working and no error.
How to confirm Many laptops have a physical shutter or a keyboard toggle for the camera. This is one of the most common causes of a black preview and takes a second to check.
- 4
The wrong device is selected in the application
What separates it No image or no sound, with a virtual camera, a dock's audio device or a disconnected external device selected.
How to confirm Applications keep their own device selection independently of the system default.
- 5
The system is muted at hardware level
What separates it No microphone input at all, with a hardware mute key or an external microphone's own switch engaged.
How to confirm Many laptops have a dedicated microphone mute key, and headsets frequently have their own inline mute.
- 6
The camera has failed
What separates it Not detected in any application and absent from the system's device list.
How to confirm This is the conclusion once permissions, shutters and other applications are ruled out.
Before you touch a setting
Record this first — changing settings destroys the evidence
Every item below stops existing the moment a reset, re-pair or settings change is made. Written down first, they are what separates the causes above; recovered afterwards, they are guesswork.
- Whether the problem affects one application or all of them — one points at permissions or device selection.
- Whether a physical privacy shutter or camera toggle is engaged.
- Whether another conferencing application is running in the background.
- Which device the application itself has selected, as opposed to the system default.
Check for a physical privacy shutter or camera toggle key
ReversibleA closed shutter gives a black image with no error at all, and it is one of the most common causes.
Check camera and microphone permissions for that specific application
ReversibleBoth platforms gate access per application and the prompt is easy to dismiss by accident.
Quit every other conferencing application completely
ReversibleOnly one application can hold the camera at a time, and closing a window does not always release it.
Check the device selected inside the application itself
ReversibleApplications keep their own device selection independently of the system default.
Check for a hardware microphone mute key or an inline headset mute
ReversibleBoth are easy to engage without noticing.
Model-specific
What is true of this model and not of its siblings
Generic advice for the product line fails here. Each item below is a property of this specific model family that changes which of the steps above apply to you.
- Model scope
- Confirm machine type/model on bottom label. Lenovo PC; machine type/model determines BIOS, dock, ports, drivers and warranty configuration.
- Tier — mainstream consumer (Windows 11)
- A mainstream, affordable Windows 11 laptop for everyday use — browsing, office, video. Modest performance versus premium/gaming lines; that is the tier. Often has some upgradeable RAM/SSD.
- Everyday performance
- Fine for light multitasking; heavy gaming/creative work will strain it. Free storage and updates keep it responsive.
- Updates & ports
- Drivers via Lenovo Vantage; usually includes USB-A and HDMI plus USB-C, so fewer adapters.
- Power path
- Internal or removable battery. Every capability that costs current — night vision, higher stream quality, longer recordings, frequent events — is paid for in runtime, so a change in behaviour after a settings change is usually a power consequence rather than a fault. Cold weather reduces usable capacity sharply.
- Symptom boundary
- This record covers Lenovo IdeaPad Slim 5 family when it camera or microphone is not working in calls. A different symptom on the same hardware, or this symptom on a different Lenovo product line, has its own record with its own causes and its own cited source.
Stop boundary
When this stops being a self-service repair
Continuing past any one of these costs more than the repair saves — in safety, in warranty, or in evidence a technician needs.
- !Treat a camera indicator light that comes on when you are not in a call as a security concern: check which application has access, review permissions, and investigate further before continuing.

Sources behind this answer
Visible sources support the visible claims. Home Product Support records the publisher, the fact used and the review date; community reports can suggest an issue but do not become a published fact on their own.
Where the manufacturer's article stops. Lenovo Support publishes this as "Camera is not detected by Skype or other programs, but is shown in Device Manager - Windows - ideapad". Title itself is ideapad-scoped; covers the camera half of this combined symptom (no separate microphone-specific article was found). Verified reachable and title-matched via the Browser tool 2026-08-28. What that article does not carry is the model boundary — it is written for a product line, and Confirm machine type/model on bottom label is the scope applied here. Where a control label, terminal, indicator pattern or reset sequence differs on your unit, the manual for that exact model is the authority, not this page and not the article.
Exact questions
Common follow-ups
My Lenovo IdeaPad Slim 5 is running slowly.+
Mainstream laptops slow when storage fills or background apps pile up. Free disk space (keep 15–20% free), disable unneeded startup apps in Task Manager, run Windows Update and Lenovo Vantage for drivers, and check whether adding RAM is possible on your model (it often helps multitasking). If it has a slow older drive, it should already be an SSD on the Slim 5 — confirm in Task Manager. Heavy gaming/creative work is simply beyond this tier, not a fault.
My camera shows a black screen in every app.+
Check for a physical privacy shutter or a camera toggle key first — many laptops have one, and when it is closed you get a black image with no error message at all, which sends people straight to reinstalling drivers. After that, check that no other conferencing application is still running in the background, because only one application can hold the camera at a time.
The camera works in one app but not another.+
That is a permissions problem rather than a hardware one. Both macOS and Windows require each application to be granted camera and microphone access individually, and the prompt is easy to dismiss without noticing. Check the privacy settings for that specific application.
Does this answer apply to every Lenovo model?+
No. It is scoped to Confirm machine type/model on bottom label. Lenovo PC; machine type/model determines BIOS, dock, ports, drivers and warranty configuration.
What should I record before troubleshooting camera or microphone or Zoom?+
Record the complete model identifier, exact message or indicator, software/firmware where visible, the operating stage and what still works.
Why is a factory reset not the first step?+
A reset can erase accounts, networks, maps, schedules or preferences without distinguishing camera, microphone, Zoom. The ordered checks preserve that evidence.
When should I stop and use qualified service?+
Do not share private recordings or grant unnecessary app access.
