Depending on the chosen configuration, the push-switch may not behave like a hard-wired on/off switch, and the user should no longer expect it simply to turn off the PC's power supply. The PC could instead go into a power saving mode such as Hibernate, where it is still under tension. Furthermore the PC can automatically power on, for example for scheduled maintenance or remote management. Users should realize that the PC can "turn itself on" and that this is normal behavior. PCs with a network card supporting RWU (Remote Wake Up) can be woken up by the network in this way. Most non-ACPI PC models equipped with a network card that supports Remote Wake Up or RPO (Remote Power On) can also be woken up or restarted by the network. It may be difficult to discover if the PC is in a low power state or is turned off (electrically isolated from the power source). Considering these points, before any maintenance action you should wake the PC and carry out a shut down (S5) to ensure it is correctly powered off. Always remove the PC power cable from the socket before any maintenance actions. This ensures that the PC is 'off' and disconnected from the power source. Please read current HP documentation on "Servicing the PC" before starting an intervention. 6
