HP Brio ba200 new power management for hp desktop pcs - Page 7

For the reasons described in "Desktop Management", it is recommended that you configure the power button to Hibernate when running Windows 2000, or to Standby if it is available on your PC model, running either Windows 2000 or Windows 98 SE. This ensures that you can perform remote management. In addition these options provide a more rapid restart than the system cold boot. Your PCs can safely remain in one of these two states when not in use, and need to be turned off only when maintenance or physical relocation of the PC is necessary. Using the Mouse The mouse cannot be used to wake up the PC from Standby or Hibernate. To wake up the PC from Standby, the user can press any key on the keyboard (from S1 only, on some HP PC models), the keyboard space bar (on some HP PC models), or the PC power button. The mouse is considered too unstable to be an effective wake-up agent, as it is subject to accidental movement or may even pick up vibration from the environment, causing unwanted wake up. To wake up from Hibernate mode, the user must press the PC power button or the space bar on models that support this feature. On some older non-ACPI HP PCs, the mouse could be used to wake the PC from a custom sleep state similar to Standby. This sleep state is no longer used since power management states are now standardized. For System Administrators Recommended Operating Systems To make use of the ACPI features provided by new HP PCs, you need Windows 98 SE or Windows 2000. In fact, on new HP PCs, one of these operating systems will be provided preloaded on the hard disk or on the CD that comes with the PC. For the fullest set of ACPI features with HP PCs, Windows 2000 is recommended. For example, Hibernate mode is only available on new HP PCs when using Windows 2000. For manageability, Windows 2000 is recommended rather than Windows 98 SE. Desktop Management New and recent HP PCs running Windows NT or Windows 95 can be powered on from the off state using RPO (Remote Power On). However, for HP PCs running Windows 98 SE, or running Windows 2000 with ACPI, you require the new HP BIOS versions which support RPO from S5 under Windows 2000 and ACPI. These BIOS versions will be announced as they become available in 2000 and early 2001. If you are planning to use remote desktop management on ACPI-based PCs, with current HP BIOS versions you should not make use of the off state (S5). Instead, Hibernate is recommended, since you can then wake up the PCs remotely using RWU (remote wake up). To ensure that Soft Off is not used, you must reconfigure the power button. Also, it is possible to remove the 6KXW'RZQ option from the Windows Start>ShutDown menu. To learn how to do this, refer to Microsoft's hardware white paper "Windows Power Management Configuration Tools Design Notes and Reference", available at ZZZPLFURVRIWFRPKZGHYGHVLQLWZSPWRROVKWP Enable RPO To enable Remote Power On, several settings may be necessary: • In the driver (e.g. under Windows 98). Power settings are accessed in Start>Settings> Control Panel >Power • In the BIOS (options vary depending on the BIOS). At boot, press F2 to open the BIOS settings and select Power Management. For networked PCs the BIOS settings may also be altered remotely using HP Toptools. See the HP Toptools documentation or website for more information. HP Utilities HP Utilities that provided power management features in non-ACPI based systems are to be phased out and are not available for Windows 98 SE or Windows 2000. The features provided by these utilities are now provided by Microsoft's ACPI-based operating systems.

If the PC is in Standby mode, there will be a flashing or yellow indicator light on the PC's front panel. 7
