The dc7800 desktop computer from HP provides several key energy efficiency and environmental advantages: 1) It has an 80%+ efficient power supply, low power processors and chipsets, and HP BIOS settings to reduce energy usage. 2) It meets various global environmental standards and certifications and is designed to be easily recycled with recycled materials. 3) HP offers services like take back and recycling programs to ensure safe disposal and reduce environmental impact over the product's lifecycle.

1. dc7800 Key Advantages for Green PC Energy Efficiency 80% Efficient power supply Low power Intel® processors and low power chipsets Advanced thermal design HP BIOS with S3 sleep state set Energy Star 4.0 compliant Verdiem Surveyor remote power management Designed with the Environment in mind Meets or exceeds global environmental regulatory standards and many voluntary standards 15+ month lifecycle Recycled plastics and packaging from post consumer waste Recycling made easier Greater energy efficiency Reduce processor heat Manage power and sleep settings more efficiently Longer useful life Reduce environmental impact for the life of the product Fewer natural resources used for a smaller environmental footprint Better for the environment HP offers take back and recycling programs to ensure products are disposed of safely

2. Energy efficiency built-in 80% efficient power supplies Low-power chipset and energy efficient processors HP BIOS efficiency settings Meets or exceeds global environmental standards EPEAT, Energy Star Submitted for certification to the following Asia Pacific eco-labels: Taiwan Green Mark, Korea Eco-label, Japan PC Green Label, CECP energy from China Eco-friendly design: easy to disassemble and recycle Services and support for recycle-ability Trade-in Program Dismantling and remarket/refurbishing Responsible use of materials RoHS Compliant Proactive elimination of brominated flame retardants in exterior case parts Why buy – Environmental features Designed with the environment in mind Save energy Lower costs Protect the environment

3. 80%+ Efficient Power Supplies What is it? Power supply that uses a higher % of power taken from “the wall” Older power supplies waste power from “the wall” Current power supplies generally are 65% to 70% efficient Why is it relevant? Energy Star 4.0 requires 80%+ Power Supplies HP was the first Tier 1 OEM to ship 80%+ in Nov. 2006 80% efficient power supplies benefit customers financially while helping the environment by reducing waste: Increased power supply reliability due to greater efficiency Decreased system maintenance due to increased reliability Lower TCO due to reduced maintenance and longer equipment life Improved worker environment with less noise from the PC Potential reduction in cooling bill due to less heat being generated by PCs.
