Hey Tiago, sorry to hear your MSI laptop's camera is acting up and not even showing up in Device Manager—let's walk through some troubleshooting steps that often fix this kind of issue:

• Check the physical camera toggle first: Most MSI laptops have either a physical switch on the side/top of the chassis or a keyboard shortcut (like Fn + F6, depending on your model) to enable/disable the camera. It's super easy to accidentally toggle this off, which would make the camera disappear from Device Manager entirely. Double-check this first—it's the simplest fix!

• Verify BIOS settings: Restart your laptop and press Del or F2 (the key varies by model, watch the on-screen prompt) to enter the BIOS menu. Look for an option labeled something like Camera Enable or Integrated Camera—make sure it's set to "Enabled". Save the changes (usually F10) and reboot to see if the camera shows up.

• Reset USB controllers: Since most integrated cameras connect via internal USB, a glitch in USB controllers can cause detection issues. Open Device Manager, click the View menu and select Show hidden devices. Expand Universal Serial Bus controllers, then right-click every entry labeled USB Root Hub or USB Host Controller and select "Uninstall device". Reboot your laptop afterward—Windows will automatically reinstall these controllers, which might resolve the camera detection problem.

• Reinstall the official MSI camera driver: Even if you tried Microsoft's steps, using the manufacturer's specific driver often works better. Head to MSI's official support page, find your exact laptop model, download the latest camera driver package. Uninstall any existing camera drivers (if you can find them in Device Manager after enabling hidden devices), then run the downloaded installer and restart your system.

• Check for Windows updates: Sometimes system-level patches fix hardware detection bugs. Open Settings > Windows Update, click Check for updates, and install any available feature updates or cumulative updates. Reboot once the updates are applied.

If none of these steps get the camera showing up in Device Manager, it might be a hardware issue—like a loose camera cable inside the laptop or a faulty camera module. In that case, reaching out to MSI's customer support for a repair or replacement would be your best bet.
