Reset Pushbutton

The reset pushbutton resets the system and forces the
power to be powered-off . Use this pushbutton when the
power is not completely off or the system is hung. See
"Rear View" on page 459 for the location of the
pushbutton.

Checking the Installed Devices List

If a device is installed but the icon appears in a gray shade
rather than a dark shade on the basic diagnostics screen,
the device is defective. Reseat the device connectors. If
the symptom remains, replace the device or the system
board. If needed, adjust the contrast control to clearly
distinguish the shades of the icon.
If a device that is not installed appears in a dark shade, for
example, FDD-2 appears in a dark shade when NO
second FDD is installed, do the following.
1. Replace the first device, such as a FDD-1, HDD-1, or
PCMCIA-1.
2. If the problem remains, replace the system board.
PCMCIA-1, Parallel, and Serial icons are always displayed
in dark shade, because the icons represent subsystems of
the system board and not attachment of the devices.
The HDD-1, FDD-1, or PCMCIA-1 represents the first
drive in the system configuration, respectively. Similarly,
the HDD-2, FDD-2, or PCMCIA-2 represents the second
drive, usually attached through a port replicator or an
expansion unit.
Password Combinations
The password relationship is:
When POP is the same as HDP
The POP prompt appears, but the HDP prompt does
not appear.
When POP is not the same as HDP
Both POP and HDP prompts appear.
PAP and HDP
When PAP is used, the HDP is enabled automatically,
but no HDP prompt appears. The HDP is set the
same as PAP.
