GEMS is a mandatory energy regulation in Australia/New Zealand. 

PCs, Monitors and External power supplies (EPS) are in scope of GEMS, and products must be certified before market entry in AUS/NZ.

HP instructs EPS suppliers to complete this certification, and all necessary information must have been delivered to suppliers. Hence, all scoped HP Products sold in AUS/NZ meet GEMS requirements and are certified accordingly.

Please note that some exemptions exist in the regulation's scope. If in doubt whether a specific HP model is regulated by GEMS, do not hesitate to submit a ticket with us.
