I'm sorry for the inconvenience.

In view of the situation you described, if the signatures of application installation are inconsistent, it may be that the application used does not support direct upgrade, and you may need to uninstall the original system. I also suggest that you go through Music Store/Lenovo/WSI/Station/ServiceStation/default.aspx? Intcmp=MIDH, the service hours of maintenance stations are generally 9:00- 18:00 from Monday to Sunday, except holidays, and local stations will adjust slightly according to their own operation conditions. I suggest you call for detailed consultation before you go. Please refer to.

Thank you for your support to Lenovo and wish you a happy life!
