We are sorry to hear that you are having issues with the screen brightness of your Lenovo Duet Chromebook. Even though you have turned off the auto-brightness setting, check your power management settings as well. Depending on the power management setting you are using, power management may be automatically diming your screen brightness to conserve battery power. This is independent of ambient light that auto-brightness uses to control screen brightness. Your power management settings lengthen your available time-on-battery by diming the screen brightness. Here is a link to instructions for accessing your power management settings on the Duet Chromebook, check your current power management settings to be sure that screen diming is not part of the function of the power management setting: https://support.google.com/chromebook/answer/3420029?hl=en. If the issue continues, we recommend you contact Lenovo Tech Support for Chromebooks at: 800-426-7378.

The Lenovo Yoga 7i 15 model number 82BJ0001US, ships with a 720p (HD) webcam with manual Privacy Shutter and Dual Array Microphones built in. If the incoming images are clear but the outgoing image is cloudy/burry, first, check to be sure that the clear shipping tape has been completely removed from the webcam lens. Since the tape cover is clear, it is hard to see. There should be a visible tab on the edge of the clear tape covering the lens to remove the tape completely. This is used during shipping to protect the lens from damage. If the shipping tape over the lens has already been removed, then check to be sure you have the latest version of Windows 10 on the computer. Then update all of the BIOS file and drivers up to that latest version of Windows 10. You can easily accomplish this by scanning the computer with the Lenovo Utility software available on this computer. This system has Lenovo utilities installed to help maintain the health of the device and keep the operating system software up to date.

Follow any directions that may pop up. If the problem continues after this scan, now click on "System Update". First select Windows update from the menu. Scan your system to be sure you have the latest version of Windows 10. Once that scan is complete, select "Additional Updates".
