| Energy efficiency makes good sense not only for your bottom line, but for the planet as well. Follow these steps, and you’re right on track towards implementing energy efficient measures in your environment. |
|
|
|
|
| Choose a system that has power management technology and enable the technology on your systems coupled with a system processor, such as AMD with Cool ‘n’ Quiet or Intel® EIST (Enhanced Intel SpeedStep® Technology), that provide the maximum level of power efficiency. |
|
|
|
|
| Choose a system configuration with an 80% efficient power supply. 80% efficient power supplies reduce energy consumption, provide peak reduction and provide improved power quality. |
|
|
|
|
| Choose a system that has a BIOS offering a wide range of configurable power management options. All HP 7000 and 5000 Series Business Desktop PCs ship out of the factory with all system states enabled to achieve maximum power efficiency. |
|
|
|
|
| Choose a system that promotes software power management options. HP is introducing HP Power Manager as an option, which provides real time reporting of how your various settings impact the energy consumed by the PC and the potential savings you might realize over time. HP also pre-installs the Verdiem Surveyor1 software agent on the HP 7000 and 5000 Series Business PCs, taking IT-wide power management to the next level. |
|
|
|
|
| Replace CRT monitors with LCD technology. LCD technology provides up to 70% power savings and provides up to twice the lifespan of CRT monitors. |
|
Step 1: Power management plus energy efficient processors |
|
|
|
|
Intel® EIST (Enhanced Intel SpeedStep® Technology) and AMD Cool ‘n’ Quiet™ were created to lessen power consumption when software activity does not require the full capabilities of the processor. Diminished power consumption means operating costs and heat production are lowered. HP ships all systems with Intel’s EIST and AMD’s Cool ‘n’ Quiet enabled. |
|
| AMD and Intel both offer energy efficient processor configurations that provide power savings. |
|
|
• |
An AMD X2 3800+ 35w processor configuration will yield the best energy efficiency versus other AMD wattage classifications. |
|
|
• |
An Intel system with a Core 2 Duo 65w processor configuration will yield the best energy efficiency. |
|
|
Step 2: Standard power supplies vs. 80% efficient power supplies |
|
|
|
| What exactly is an 80% efficient power supply? When a power supply converts AC power from the wall to the various DC voltages that the computer needs, there is always a loss of power. The power loss varies with how busy the computer is. An 80% efficient power supply is guaranteed to lose less than 20% of the AC power at 20%, 50% and 100% loads. Currently, power supplies for desktop computers range from approximately 65% to 75% efficiency. |
|
| Other benefits of the new 80% efficient power supplies are: |
|
|
• |
Decreased system maintenance due to increased reliability |
|
• |
Reduced maintenance and longer equipment life |
|
• |
Improved worker environment due to use of quieter fans |
|
• |
Less heat generated leads to lower air conditioning cost |
|
|
| 80% efficient power supplies are available as an option on the 7000 and 5000 Series of Business Desktops. HP was the first tier 1 OEM to provide this energy saving solution to customers and offers great flexibility as it can be configured into any system configuration. When thinking of energy savings, configuring your system with an 80% efficient power supply is a great way to save on your energy bill while helping the environment.

|
Step 3: The HP BIOS |
|
|
|
| You probably don’t think much about your BIOS settings, but the HP BIOS offers a range of configurable power management options, including a Standby state (S3) known as Suspend to RAM, in which all devices in the system are powered down, except for computer memory. Recovery is almost instant (approximately 2 to 3 seconds) and power consumption is very low (typically <5W). |
|
Step 4: Choose a system that provides software power management options. |
|
|
|
| All HP Business Desktops can be configured with HP Power Manager. This easy-to-use end user tool lets you configure your PC power settings so you can save energy without interfering with your ability to perform your work. HP Power Manager gives you control of how long after being idle your computer: |
|
| |
• |
Shuts off your display |
| |
• |
Spins down your hard drives |
| |
• |
Suspends your system |
|
|
| Additionally, all HP 7000 and 5000 Series Business Desktops have the Verdiem Surveyor agent pre-installed. Verdiem Surveyor allows you to manage IT power management policy IT-wide. |
|
Step 5: Upgrade to LCD |
|
|
|
| Replacing CRT technology with LCD technology can provide substantial power savings. For example, a floor with 100 CRT monitors requires an approximate energy consumption of 9,000 Watts per hour (W/Hr), versus only 1700 W/Hr when equipped with comparable 15-inch LCD monitors. |
|
ENERGY STAR® 4.0 – what’s changed? |
|
|
|
| When making a purchase decision, consider systems that are ENERGY STAR® qualified. ENERGY STAR® qualified products use less energy and prevent greenhouse gas emissions. A new ENERGY STAR® 4.0 PC specification went into effect on July 20, 2007 and can help to further reduce energy consumption. |
|
| Another helpful guide is EPEAT™ (Electronic Product Environmental Assessment Tool). EPEAT is a system to help purchasers in both the public and private sectors evaluate, compare and select desktop computers, notebooks and monitors base on their environmental attributes. |
|
| If your organization is serious about energy efficiency, HP offers a wide selection of energy efficient solutions to get you started or to enhance your energy reduction goals. |
