Hi B, thank you for contacting us.
I am sorry to hear that there are some problems logging in on your laptop and our team will do everything we can to help!
It sounds like the browser on your laptop might be preventing WordPress from creating the login cookie needed to access your website dashboard. If you have any browser extensions active you could try deactivating them to see if that fixes the issue. Does the login work correctly if you use a different browser? There could also be some redirection errors and another thing you can try is accessing the login URL directly by going to http://yourdomain.com/wp-login.php
Hopefully one of those solutions works for you and please let us know if there is anything else that we can do to assist you.
