Power Saving and Ergonometry

Power-On from Space-Bar

The power-on from the space-barfunction is enabled, provided that:

•The computer is connected to a Windows 95 keyboard (recognizable by the Power-On icon on the space bar).

•The computer is running the Windows 95 operating system.

•The function has not been disabled by setting SW-9 to closed on the sys- tem board switches.

•The function has not been disabled in the “Power” menu of the Setup pro- gram.

Soft Power Down

When the user requests the operating system to shutdown, the environment is cleared, and the computer is powered off. At the time of release, the drivers bear the version number A.01.00 (or SPD.02.01 for Windows NT 4.0). They are supplied with Windows NT and Windows 95. Soft Power Down is not available with OS/2.

The hardware to do this, and the complement function, HP Off (as described in the next section), is contained within the HP ASIC chip, LittleBen. This chip is described on page 73.

HP Off

If the user attempts to turn the PC off at the status panel, the PC logic will delay the shutting down of the power supply until it is safe to do so. HP Off protects the user from some types of unintentional data loss, providing a safe shutdown of running applications and unsaved files. It is available under the Windows 95 operating system provided that the appropriate driver is installed.
