Mobile PC Extended Battery Life Working Group Releases Guidelines for Display Power Measurement

Ratification and Formal Standardization to Follow Through VESA

HILLSBORO, OR--(Marketwire - December 18, 2008) - The Mobile PC Extended Battery Life Working Group (EBL WG) released today updated guidelines for measurement of notebook PC display power. The 2008 EBL WG Display Measurement Guidelines is a revision to those first released by the EBL WG in 2003. The display is the top power consuming platform ingredient in a typical notebook PC. The power measurement methodologies contained in the guidelines are part of the mobile PC industry's effort to find ways to continue to reduce the power consumption of notebook PC liquid crystal displays (LCDs) and extend battery life.

The newly revised guidelines include support for both the CCFL (Cold Cathode Fluorescent Lamp) and LED (Light Emitting Diode) backlight technologies and associated electronics that drive them. The document also provides comprehensive information about lab setup, equipment to use and step-by-step instructions for power measurement. A template for generating a power measurement report is also provided to aid the user in providing a uniform and consistent presentation of results.

"As we continue to work towards reducing power consumption of notebook PCs, it is essential to ensure that the industry's power measurement methodologies are consistent, comprehensive and easy to use," said Kamal Shah, manager, Mobility Enabling Initiative, Mobile Platforms Group, Intel and chairman of the Mobile PC Extended Battery Life Working Group. "These guidelines will provide a way to identify the lowest power consuming displays and help further display power reduction innovations industry wide."

"As a leading maker of notebook PCs worldwide, supporting our customers' need for longer battery life is essential," said Stefan Peana, LCD engineering senior manager and global display specialist at Dell Austin Engineering Design Center. "The standardization of a measurement technique will greatly simplify the integration and qualification efforts of computer designers and manufacturers. In addition, standardized reporting of results will foster a more competitive environment for display makers in terms of their power reduction efforts."

"The EBL WG has been instrumental in helping evangelize the need for display power reduction," said Vivek Agarwal, director, Customer Platforms Enabling, Mobile Platforms Group, Intel Corp. "The group's efforts have helped the industry move towards substantially lower power displays. These new guidelines are an important step in the right direction."

"We compliment the EBL WG for its leadership in delivering these guidelines," said Brian Berkeley, vice president of engineering, Samsung Electronics Co. LCD Business. "This will help us serve our OEM customers better by providing power data measurement in a standardized fashion."

As part of the collaboration between the EBL WG and Video Electronics Standards Association (VESA), the EBL WG has engaged VESA to ratify and maintain the document as a VESA standard. VESA is widely regarded as the leading organization for developing and maintaining standards for a variety of technology areas, with a focus on display devices. Information about VESA can be found at

"The EBL document is another key component in VESA's panel standards efforts," said Bill Lempesis, executive director, VESA. "As the leader worldwide in display standards, we look forward to ratifying the document as a VESA standard and promoting the new standard worldwide."

About the Mobile PC Extended Battery Life Working Group

The Mobile PC Extended Battery Life Working Group (EBL WG) is an industry group dedicated to realizing the vision of all-day and beyond battery life. The group's inception was announced in October 2002. The group focuses on platform power reduction, as well as support of safe and high capacity power sources. As mobile PCs become an integral part of business and non-business users, the need for longer battery life is paramount to support anyplace, anytime computing.

The 2008 EBL WG Display Measurement Guidelines are available from the EBL WG web site in the public document section. For more information about the EBL WG visit or contact for membership information.
