error0210 is probably the O key. I found this information from Lenovo Service Site. Hope it is usefull.
You can test your key codes on this site
, and as others have already discoverd and from my past experience key code 28 indicates that your error is coming from the apostrophe key. Sometimes due to normal use, keyboards may not fully release a key after it has been pressed. I would recommend getting some compressed air and try cleaning the keyboard, it is possible something is stopping it from releasing.
Since it seems that you are having mulitple errors I reccomend is to verify that your drivers are up-to-date, you can do so from the Lenovo Driver Matrix
However, if this does not fix your error, it is possible the error has something to do with the BIOS Settings. You may boot to the BIOS and set it back to factory settings and check if the issue persists. To enter BIOS press the F1 immediately after the logo screen appears. Prior to the reset back up all of your information so that you do not lose anything as a precautionary measure.
Also, as others have stated if your device is under warranty, you may contact your local Lenovo Service Center
for further assistance.
