Workstation will not respond to USB keyboard or mouse. Workstation is in standby mode. Press the power button to resume from standby mode.

First, reset the date and time using Computer Setup (F10). If the problem persists, replace the RTC battery. See the Service and Technical Reference Guide for instructions on installing a new battery, or contact an authorized dealer or reseller for RTC battery replacement.
