1. Check to see if the touchscreen keyboard works. First, go to the login screen, and select the “Ease of Access” button on the bottom left. Then select the box that says “Type without the keyboard (On-Screen Keyboard).” Check to see if both the touchscreen and physically keys respond.
2. Disable addition keyboard features. Go to the Control Panel, select “Ease of Access,” then “Ease of Access Center,” and lastly “Make the keyboard easier to use (adjust setting for the keyboard).” Deselect all options, press “Apply Settings,” and restart the laptop.
3. Determine if the problem is hardware or software. Check to see if keys work under “Command Prompt.” To do this, press the keys Windows + X at the same time, and select “Command Prompt” from the menu (works only for Windows 10/8.1/8). If you have Windows 7, go to the start menu at the bottom left and in the search bar type “Command Prompt,” then select the option. In the Command Prompt Window try the stuck keys. If they work, it is a software problem, if not, it may be a hardware issue that requires you to contact Lenovo Customer Support to get the keyboard replaced.
