HP Lock Installation Notes for Vectra PCs under Win NT4.0 (Build 1381)

Before installing this version of HP Lock, it is necessary to uninstall any older version of NTLOCK and any version of SOFTPOWERDOWN older than SPD0602 already installed.

If this version is installed on top of NTLOCK 2.11 please look at the section "Installation warning" before installing this version.

HP Lock provides an enhanced solution for security, ergonomy and power management in the Windows NT environment. With HP Lock you can:

• Prevent unauthorized use of the computer by locking the keyboard, mouse, and On/Off switch. This is a Lock feature.
• Prevent data loss if the user powers off the computer without first saving data and performing a system shut down. This is the Safe-Off feature that is part of HP Lock.
• Automatically power off the HP Vectra or PC Workstation when the operating system is shut down. The HP Soft Power down Software application should be installed too.
• Hide the screen using the HP Energy Saver screen saver when the computer is locked.
• Activate the enhanced security and power management features when the Pause button on your Vectra or PC Workstation front panel is pressed.

HP Lock has been designed for Windows NT 4.0.

It is based on specific BIOS support functions but is compatible with all legacy BIOS supporting HP Private Entries. More or less HP Lock functionalities are available, depending on what functions are supported by your BIOS.

HP Lock is intended for use on x86 processors only (single or dual

processors), and on HP Vectra or HP Kayak only.

It is recommended that you set the Low Power Standby time-out within the range 30 to 60 minutes. (If you set a lower value, you may affect the life expectancy of connected disks.)

It is also recommended that you set the Disks Low Power Standby time-out greater than the Monitor Low Power Standby time-out and/or the Shut Off Monitor time-out.

When using more than 1 IDE disk in your system, boot time may be slightly longer (3 seconds more maximum), due to power management initialization. This is not the case while using any number SCSI disks.

When using SCSI disks in your system, it is required to explicitly set, at least one time, disks settings in HP Lock applet, to ensure proper power management initialization.

This is not the case while using any number IDE disks.

Note: Power management of SCSI disks IS NOT supported on systems using one of the following piece of hardware (typically, Kayak systems):

• a SCSI Adaptec Fast Raid solution,
• a 3D Graphic adapter Visualize Fx,
• a 3D Graphic adapter Accel Eclipse.

Disks power management can be partially supported on systems using both IDE and SCSI disks, especially if more than 4 disks are connected. That is, if you're using 2 SCSI disks on an Adaptec adapter and 2 IDE disks, only one of the two SCSI disks will be power managed; and both IDE disks will be power managed.

Power management of the monitor IS supported on systems using a 3D Graphic adapter Visualize Fx, but having the monitor switched in standby mode can take longer than configured time-outs.

Remark1: Check your system is using a SCSI Adaptec Fast Raid solution by:

• going to your Windows NT Control Panel
• running the SCSI Adapters applet
• going to the Drivers property page
• checking that Cda1000 driver is installed

Remark2: You can discover which 3D Graphic adapter your system is using by:

• going to your Windows NT Control Panel
• running the Display applet
• going to the Settings property page, and then clicking on Display Type
• checking what adapter type is installed

• HPGina.dll V1.25: Fix for the HPSmartLock service bug when HPGina is used in a chain.

• Windows NT4 SP4 systems access the hard disk approximately every five minutes. This access interferes with Power Management. To disable it, the following entry "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Reliability\TimeStampInterval" is set to 0. (See Microsoft Support Article Q194749)
