Power-On from Space-Bar

The power-on from the space-bar function 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
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.
