Resetting the power supply If an overload triggers the power supply overload protection, power is immediately disconnected. To reset the power supply: 1. Disconnect the power cord from the workstation. 2. Determine what caused the overload and fix the problem. For troubleshooting information, see System diagnostics and troubleshooting on page 113. 3. Reconnect the power cord and reboot the workstation. When you power off the workstation through the operating system, power consumption falls below what is considered low power consumption but does not reach zero. This low power consumption feature extends the life of the power supply. Environmental specifications The following table lists the environmental specifications of your workstation.

ENERGY STAR Qualification HP computers marked with the ENERGY STAR logo are compliant with the applicable U.S. Environmental Protection Agency (EPA) ENERGY STAR specifications for computers. The EPA ENERGY STAR logo does not imply endorsement by the EPA. As an ENERGY STAR Partner, HewlettPackard Company has determined the products marked with the ENERGY STAR logo are ENERGY STAR qualified per the applicable ENERGY STAR guidelines for energy efficiency.
