Key features
This section defines the purpose and function of key features of IBM® Endpoint Manager Power® Management:
- PC Insomnia Prevention
- Computers can be set to go into sleep states after configurable amounts of user idle time. The term PC Insomnia is used to describe a situation where applications prevent a computer from sleeping. PC Insomnia Prevention is a mechanism that the IBM Endpoint Manager agent uses to monitor user idle time and force the computer to sleep at the appropriate times.
- Wake-on-LAN Forwarder (WoLF)
- Many enterprise networks do not allow broadcasting from different subnets, which makes Wake-on-LAN difficult. To solve this issue, IBM Endpoint Manager agents can be designated as Wake-on-LAN Forwarders (WoLFs), which send the Wake-on-LAN packets to nearby computers in the same subnet. This method allows organizations to use Wake-on-LAN without requiring network changes.
- Last Man Standing (LMS)
- Wake-on-LAN technology requires at least one computer in a subnet to be active to serve as Wake-on-LAN Forwarder for other computers. An LMS-designated computer ensures that a computer is always active by resisting shutdowns and by automatically being awakened if powered off.
- Power Management Efficiency
- A measure of how efficiently a computer spends its non-active time, whereby Idle Time is considered inefficient and standby is efficient. The formula is: Standby Time / (Standby Time + Idle Time).
- Minimum Power Consumption
- The amount of power used by a computer if it is only powered on when in active use and powered off at all other times.
- Full Power Consumption
- The amount of power used if a computer was powered on all day without any power management settings enabled.
