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.
