Argentina safety certificates are publicly available on http://www.hp.eu/certificates. Alternatively, you could log in a ticket with us by writing an email to techregshelp@hp.com.
For Notebooks, these certificates are based on their power adapters. Therefore, when importing Notebooks, you need to provide the certificates for their adapters instead.
If you need more precise information about the compatible adapter to the host in question you should provide product identification information such as Serial Number or Product number with proper localization codes.
