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
Diagnostics and troubleshooting on page 150.
3. Reconnect the power cord and restart 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.
