Power consumption settings – OS control
To take advantage of the Linux operating system’s ability to adjust server power consumption (and reduce costs) based
on workload, follow these steps:
1. During system boot, press F9 to run the ROM-Based Setup Utility (RBSU).
2. Select Power Management Options.
3. Select HP Power Regulator.
4. Select OS Control Mode (see Figure 3).
5. Exit all RBSU menu screens using the Esc key.
6. Press the F10 key to confirm your changes and reboot the system.
Note
OS Control mode is not recommended for high, predictable performance
implementations.
