Each HP Proactive Care Advanced Service level includes problem prevention and incident management support for hardware and software products. For hardware products, the HP Proactive Care Advanced portfolio offers distinct hardware service levels. The HP Proactive Care Advanced portfolio also offers the same service levels with the comprehensive defective material retention (CDMR) as additional optional features.
