I often get an “Access Denied” error when trying to access the Lenovo communities, especially after signing into the main Lenovo site. It usually fixes itself after a few minutes, but I’ve found that you can also open an incognito window and sign in again from there if you don’t want to wait. This also seems to work if you get locked out of the main site or run into issues where some shop buttons, like “Add to Cart,” don’t respond.
