A:Answer We are sorry to hear that you are having issues with the keyboard of your Intel Evo-Certified, lenovo Yoga 9i 14 model number 82BG0090US. Using the Touch screen, check to be sure you have the latest version of Windows 11 on the computer. Then update all BIOS files and drivers up to that latest version of Windows 11, including those BIOS files and drivers that control the keyboard functions. 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. Type "Lenovo Vantage" in the Cortana Search window (if Lenovo Vantage is not installed on your device, you can download the APP and install it now). Select Lenovo Vantage from the list. In the window that opens, click on "Health and Support". In the expanded menu, select "Hardware Scan" In the window that opens, select "Run Quick Tests". This will scan your entire system for errors.
