Lenovo and Cisco, two high-tech firms with a major presence in the Triangle, are teaming up in an effort to help customers save on energy costs.

The world’s No. 4 PC maker said Wednesday that that it is the first PC maker to embed Cisco EnergyWise software on some models of its ThinkPad laptops. Cisco offers an energy management service through networks that utilize its Catalyst brand switches.

Financial terms were not disclosed.

The software can be used to monitor laptops and other devices linked to the Cisco network.

ThinkPad laptops included in the effort are ThinkPad Edge, L, R, T, X, W and SL Series.

The companies believe the Cisco software can cut energy bills by 35 percent.

“Lenovo pre-integrating Cisco EnergyWise in their ThinkPad laptops enables our customers to expand the value of their Cisco network without installing any additional software,” said Jeff Reed, vice president of Cisco’s Unified Access Business Unit. “Now our catalyst switching customers have a highly accurate PC energy management solution that delivers impressive energy savings at no extra cost to our customers.”

Information technology managers can monitor devices and shift them to “sleep” mode, battery mode and low-power mode.

“Since PCs are such a keystone within a business’ IT infrastructure, embedding Cisco EnergyWise on our ThinkPad laptops makes it easier for large customers to gain an accurate, holistic view of their organization’s IT energy consumption so they can optimize their assets and reduce costs,” said Dilip Bhatia, general manager of Lenovo’s ThinkPad business unit.

Lenovo operates its headquarters in Morrisville.

Cisco maintains its second largest campus outside of its Silicon Valley headquarters in RTP.
