Environmental Product Design for Notebook PCs

HP designs products to minimize their impact on the environment by reducing or eliminating hazardous materials, using fewer resources, reducing energy consumption and designing for recyclability. This section describes the actions taken for each product family.

Notebook PCs

Reduction of hazardous materials

  • Plastics greater than 25 grams have no halogenated flame retardants

  • No use of polyvinyl chloride (PVC) except for cables.

  • No use of polybrominated biphenyls (PBBs), polybrominated biphenyl ethers (PBDEs) also known as polybrominated biphenyl oxides (PBDOs)

  • Batteries do not contain mercury or cadmium or do not contain mercury or cadmium at a concentration currently prohibited by law.

  • Cadmium has not been used as a stabilizer, coloring agent or as a surface treatment for any parts, components or material in this product.

  • Mercury in laptops is less than 5mG per LCD

  • No use of ozone depleting substances in product manufacturing

Resource conservation

  • Packaging is made of 66% minimum of post-consumer recycled cardboard.

  • Manuals are printed on elementary chlorine free (EFC) bleached virgin or recycled paper or put on CD-ROM to minimize paper use

Power consumption

  • All Business and Consumer notebook PCs are ENERGY STAR® qualified

  • Some notebook PCs with Intel SpeedStep Technology enables the processor to automatically switch to lower, power-saving speeds or switch to higher-performance speeds according to the workload.

  • Set display brightness to lowest comfort level to conserve energy / battery life

Power management settings

Power-saving modes on HP Notebook PCs are configurable and pre-set at the factory to conserve power and battery life. To further increase energy savings, users can reduce the factory default time delay settings from the factory default settings as described in the user manual. Users can also manually send notebook PCs into a power saving mode at any time by pressing the appropriate key described in the user manual.

Standby mode

  • Saves significant power
  • Turns off the display and other components
  • Maintains current session in RAM
  • Restarts quickly
  • Restores network connections
  • Power mode status light is blinking
  • Customers instructed not to disable standby mode
  • Default setting on AC power = standby within 20 minutes of inactivity
  • Default setting on battery power = standby within 5 minutes of inactivity

Hibernate mode

  • Saves maximum power
  • Saves current session to disk, then shuts down
  • Restores network connections
  • Power mode status light is off
  • Default setting on AC power = hibernate within 3 hours of inactivity
  • Default setting on battery power = hibernate within 2 hours of inactivity

Design for recycling

  • Marking plastic parts weighing more than 25 grams according to ISO 11469 for easier sorting

  • This product is designed for easy disassembly during recycling. Use of glues, adhesives and welds from product construction has been avoided where feasible

  • Large mechanical plastic parts consist of one material or are made of easily separable materials

  • The product uses common fasteners

  • The product includes snap-in features
