HP 742n - Pavilion - 512 MB RAM Weißbuch

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.

Servicing the PC

Before upgrading or servicing the PC, it is very

important to ensure that the PC is off (in S5 mode) and

not in Hibernation mode (S4).

If the PC is in Standby mode, there will be a flashing or

yellow indicator light on the PC's front panel.
