1. OVERVIEW
===========

Your computer is equipped with two features which allow your computer to 
save energy.  Standby is a feature that allows your computer to enter a low 
energy mode during periods of inactivity.  Rapid Resume is a feature that 
allows you to quickly access your applications and automatically turn your 
computer off after a selected period of inactivity.



1.1 Standby 
-----------

You can set your computer to automatically enter Standby when it remains 
inactive for a period of time.  Your computer is inactive when you have not 
used the keyboard, mouse or hard disk.  This is the only way to enter 
Standby.  When activity is sensed the computer will automatically exit 
Standby.  

While in Standby, the computer continues to function and process information 
in a lower energy mode.  Network connections and communications are not 
disturbed.  The computer's display output is blanked by removing the SYNC 
and RGB signals.  This allows displays supporting the VESA energy savings 
modes to automatically enter a lower energy mode and/or turn off.  In 
addition, the hard disks are given a command to enter a lower energy mode.  
If an application needs to access the hard disks while they are in the low 
energy mode, the hard disks will automatically return to the higher energy 
mode for the application to use.




1.2 Rapid Resume
----------------

When the Rapid Resume feature is enabled your computer is enhanced in the 
following ways:

- When you use the On/Off button on the system unit to turn the computer   
  off, Rapid Resume will remember where you were in your applications. When 
  you use the On/Off button on the system unit to turn the computer on again, 
  it will return to where you were in your applications.  Use the PS/1 Fitness 
  program (in Windows) or the Configuration Utility to enable the Rapid Resume 
  feature.

- You may enable the Automatic Power Off option so your computer will 
  automatically power off after a selected period of inactivity.

   


1.3 Turning Your Computer Off
-----------------------------

When Rapid Resume is enabled, pressing the On/Off button on the system unit 
automatically remembers the state of the computer and turns it off.  You 
should still turn off the display and other devices connected to your 
computer by using their switches.   If you want to temporarily bypass Rapid 
Resume and turn your computer off in a conventional manner press the 
On/Off button on the computer followed by pressing the Ctrl+Alt+Delete keys.

  Note: If you press the On/Off button and you hear three short beeps, 
        this is an indication that Rapid Resume cannot proceed.
        You should press the On/Off button again to cancel the 
        Rapid Resume and save your work before turning off the computer.
        If you do not press the On/Off button again, the computer will 
        turn off in a conventional manner in approximately 10 seconds.
        When the computer is turned on again it will NOT perform a 
        Rapid Resume.

You can use the Rapid Resume feature to automatically turn off your computer 
when it is inactive for a period of time.  This is called Automatic Power 
Off.  This provides a way to automatically save energy when you leave your 
computer for long periods of time.

  Note: The Automatic Power Off feature operates independently of the 
        Standby feature. 

When Rapid Resume is used to turn the computer off, the computer does NOT 
continue to process any information.  All work in progress is stopped and 
the computer is powered off.  All network connections and communications 
will be broken and may not function correctly when the computer is turned on 
again.

  Note: The On/Off button may be pressed again before the computer powers
        off to cancel the Rapid Resume. 



1.4 Turning Your Computer On
----------------------------

When the computer is turned on with Rapid Resume, an abbreviated test of 
the computer hardware is performed and the Rapid Resume process is started.  
If you do not want to use Rapid Resume, press the Ctrl+Alt+Delete keys to 
bypass the Rapid Resume and restart the computer.

  Note: Bypassing a Rapid Resume could result in loss of information if
        the data files were not saved to disk.  

If you change your hardware configuration (for example, decrease your 
memory) the computer may give you a configuration message indicating that 
the computer cannot perform a Rapid Resume with the current hardware 
configuration. The user is given one of two choices.  One, cancel the Rapid 
Resume and restart the computer.  Or two, restore the hardware configuration 
back to its previous state and perform a Rapid Resume. 

Under Windows, a task list will appear when the computer performs a Rapid 
Resume.  This shows what applications are open and provides an easy way to 
get back to the Program Manager. You may disable the task list by using the
Rapid Resume Manager in the PS/1 Fitness program.




2. RAPID RESUME DETAILS
=======================

2.1 Advanced Power Management (APM) Device Drivers 
--------------------------------------------------

Your computer contains an Advanced Power Management (APM) Basic Input/Output 
System (BIOS) that controls the energy saving functions in your computer. 
The Rapid Resume feature requires an operating system with APM support to 
work. The Rapid Resume feature is NOT available on operating systems that do 
not support APM.  When no APM driver is loaded, the On/Off button operates 
in a conventional manner and Rapid Resume will not work.  Typically an APM 
driver is loaded by the operating system and it communicates with the APM 
BIOS to control the computer.

The APM driver will periodically poll the APM BIOS to see if there are any 
requests from the computer and will issue commands to the APM BIOS to 
control the computer.  When the On/Off button is pressed , the request is 
passed along to the operating system.  The operating system may perform 
other functions before generating a suspend command to the APM BIOS.  This 
can result in a delay of several seconds between the button press and when 
the Rapid Resume process starts.

If  the APM driver does not respond to the BIOS suspend request within 
approximately 10 seconds, the computer will turn off in a conventional 
manner.  The computer will NOT perform a Rapid Resume when it is turned back 
on.

  Note: The Windows APM driver must be enabled in the advanced 
        mode (default) in order for Rapid Resume to work.  Use the
        "Power" control in the Windows Control Panel to modify the
        APM driver settings. 

The APM BIOS supports REAL and 16/32 bit protected mode connections.  These
modes can be selected in the Configuration Utility.  The default is 32 bit
for Windows.  For other operating systems, you may need to enable the 16 bit
mode or both.




2.2 Periods of Inactivity
-------------------------

The time values for Standby and Automatic Power Off are based on inactivity 
with the keyboard, mouse or hard disk.  Other activity such as 
communications or printing that does not access the hard disk or involve the 
keyboard/mouse will not be seen as activity and will not prevent the 
computer from entering Standby or Automatic Power Off.  Use the Standby and 
Rapid Resume Manager in PS/1 Fitness to set the time values or disable the 
features.




2.3 Other Operating Systems
---------------------------

Your computer comes with the Windows APM driver already loaded ("POWER.DRV" 
in the Windows "SYSTEM.INI").  To use the Rapid Resume feature without 
Windows, an APM driver must be loaded for that operating system.  See the 
operating system documentation for more information.

For DOS 6.0 and higher, there is a "POWER.EXE" driver that must be loaded in
the CONFIG.SYS file with the "DEVICE=C:\DOS\POWER.EXE ADV:MIN" command.  
This driver will enable the Rapid Resume to work under DOS without Windows.

For OS/2 2.1 and higher, the APM driver in the operating system must be 
installed and enabled.  You will need to create a Rapid Resume partition on 
the hard disk.  See the "Rapid Resume Partition" section for more information.
The APM BIOS Mode in the Configuration Utility should be set to 16 bit. 



2.4 Rapid Resume File  
---------------------

In order for the Rapid Resume feature to work, it needs to have a place to 
store computer memory and other computer information when the computer is 
off.  Rapid Resume stores the information on the computer hard disk in either 
a DOS FAT file system or a special hard disk partition (for other operating 
systems).

For DOS FAT file systems (including Windows), the information is stored on the 
root directory of the host drive as a hidden system file called "_PS1SAVE.DAT".  
This file is allocated as consecutive disk sectors and must not be deleted or 
reallocated in order for Rapid Resume to work. Every time the computer is 
started, a program called "PS1PFILE.EXE" is run from the AUTOEXEC.BAT that 
determines the amount of disk space needed and allocates this file.  If you 
add or reduce computer memory, this program will automatically adjust the file 
size.

The size of the Rapid Resume storage area is the sum of Random Access 
Memory (RAM) plus video memory plus 64KB for Rapid Resume overhead.

 SIZE = RAM + VIDEO_MEMORY + 64KB

In certain cases where the PS1PFILE.EXE program cannot allocate the storage
area due to fragmentation of the Host drive, you must perform the following
steps in order to continue using the Rapid Resume feature:

1. Temporarily reduce the size of the C: (compressed) drive by:
                DBLSPACE /SIZE C:

2. Defragment the compressed drive by:
                DEFRAG C: /F /H
   This may take several minutes.

3. Reboot to allow the PS1PFILE.EXE program to allocate the storage area.

4. Resize the C: drive by:
                DBLSPACE /SIZE /RES=4 C:
   This will reserve 4 Megabytes of uncompressed hard disk space on the
   Host drive.  You may change the RES= value if you wish.




2.5 Rapid Resume Partition 
--------------------------

If you are using Rapid Resume with operating systems that do not support the 
DOS FAT file system, then you will need to allocate a partition on the hard 
disk.  The size of the partition must be equal to or greater than the sum of 
RAM, video memory, plus 64KB. If you plan on increasing your computer 
memory, be sure to allocate a partition with enough space because you cannot 
dynamically adjust the partition size.

Follow these steps to create a partition on the hard disk for Rapid Resume:

1. Make sure you have a PS/1 RECOVERY diskette, original PS/1 software 
diskettes and a backup of your data.

2. Using the DOS hard disk partition tool (FDISK), or the hard disk 
partition tool that came with your operating system, allocate the partitions 
needed for your operating system.  Leave an area unallocated that is large 
enough for Rapid Resume.

3. Boot your computer with the PS/1 RECOVERY diskette and run the program 
called "PS1PART.EXE" to allocate the Rapid Resume partition from the 
unallocated space on the hard disk.  

4. Install the operating system.





3. SOFTWARE CONSIDERATIONS
==========================

3.1 Save your Data Files
------------------------

When you are working with applications  that create files or modify data on 
the hard disk, it is very important to use the file save commands built into 
the application to save your work often.  Although Rapid Resume remembers 
the state of your computer, it does not save your data files.



3.2 Communications Programs
---------------------------

When you use Rapid Resume to turn off your computer, all communication 
activity is stopped.  The connection to the online service or "host" 
computer is broken and typically cannot be restored.  Most communication 
programs will detect a communications error and notify you when you turn on 
the computer. You should exit the communications program and restart it 
after performing a Rapid Resume.



3.3 Networks
------------

If you are connected to a network, you should log off the network before you 
use Rapid Resume to turn off your computer.  When you turn on the computer, 
log on to the network. This helps to reduce confusion to the network server 
and increases computer security.  To use Rapid Resume with network cards, 
see the Hardware Considerations section.



3.4 Security
------------

You can increase the security of the computer environment by using the 
Windows screen saver or another screen saver program that has password 
support.  Set the screen saver timeout value to a value less than the 
Standby or Automatic Power Off time value to allow the screen saver password 
to appear.  A password will be required to continue.  However, a user could 
press Ctrl+Alt+Delete to restart the computer. 

The computer can be further secured by setting a Power-on Password in the 
Configuration Utility.  This password must be entered each time you start 
the computer before you can begin using the computer.  This protects the 
Rapid Resume from being canceled by another user.



3.5 RESUME.EXE 
--------------

The file RESUME.EXE is responsible for starting the Rapid Resume process 
when the "Initialize Adapter Cards" feature is enabled in the Configuration 
Utility. The line containing the RESUME.EXE command should be near the 
bottom of the AUTOEXEC.BAT file, but before the HWCHECK and PS1START 
commands.

For normal use of the "Initialize Adapter Cards" feature, no editing should be 
required in the CONFIG.SYS or AUTOEXEC.BAT.  However, after installing 
software or device drivers on your system, the RESUME.EXE may need to be moved 
to a later position in the AUTOEXEC.BAT.  This is accomplished by editing the 
AUTOEXEC.BAT file.  Do not remove RESUME.EXE from your AUTOEXEC.BAT file as 
this would prevent Rapid Resume from working.







4. HARDWARE CONSIDERATIONS 
==========================

4.1 Computers with Adapter Cards
--------------------------------

When the computer is turned off, information that is stored or initialized in 
adapter cards in the computer may be lost.  For some adapter cards, 
initialization occurs every time the computer is turned on. These types of 
cards usually do not represent a problem to the Rapid Resume feature.

Other adapter cards are initialized when device drivers or applications are 
run. When the computer performs a Rapid Resume, the information in these 
adapter cards is not restored.  This may cause a problem with the 
application using the adapter card.  Rapid Resume has a feature called 
"Initialize Adapter Cards" located in the Configuration Utility that allows 
the user to initialize the adapters cards before a Rapid Resume.  When this 
feature is enabled, the "CONFIG.SYS" and "AUTOEXEC.BAT" files are executed 
before the Rapid Resume.   When the "RESUME.EXE" file is executed, the 
computer will then start the Rapid Resume process.  See the "RESUME.EXE" 
section for more information.

While Rapid Resume is enabled, the computer will automatically detect 
adapter cards and enable the "Initialize Adapter Cards" feature.  The 
automatic detection can also be disabled and enabled from the Configuration 
Utility.  

The installation procedures for each adapter card should be followed according 
to the manufacturer's instructions.  




4.2 Tips for Adapter Cards
--------------------------

These are tips for using common adapter cards while you have Rapid Resume 
enabled.


Joystick and Game Cards

Since joystick and similar adapter cards typically have no software drivers, 
the cards usually do not need to be re-initialized.  You may want to turn 
off the "Initialize Adapter Cards" feature in the Configuration Utility.


Sound and Multi-Media Cards

These types of cards should be re-initialized with the "Initialize Adapter 
Cards" feature.  Depending on the card being used, the drivers will appear 
in the CONFIG.SYS or in AUTOEXEC.BAT.  To insure proper operation, these 
drivers should be placed BEFORE the RESUME.EXE command in the AUTOEXEC.BAT.  
See the section on RESUME.EXE for more information.

If Rapid Resume is used while a sound/multi-media card is in use, the 
application using the card may have to be restarted to insure correct 
operation.

Some settings on these cards cannot be reset using device drivers.  In this 
case, they can usually be set by an application after the computer is 
restarted. For example, volume levels may need to be set using the programs 
provided with the card.


Modem Cards

After a Rapid Resume, the modem is returned to its power on state.  Commands 
previously sent to the modem will be lost.  You will need to exit and 
restart the application using the modem to initialize the modem again.

Unless your modem has drivers that must be loaded to operate your modem, the 
modem should not require re-initialization. Most applications will 
re-initialize the modem when the application is started.  



SCSI Cards

When using SCSI cards and devices with Rapid Resume, you should 
re-initialize adapter drivers.  Make sure the SCSI device drivers are before 
the "RESUME.EXE" in the AUTOEXEC.BAT.



Token Ring Network Cards

Because of the complexity  of  Token Ring cards, they will not operate with
Rapid Resume.  The Rapid Resume feature should be disabled.  You may continue 
to use Standby with the Token Ring adapter. 


Ethernet Network Cards

The following operations must be performed to insure correct operation of 
Ethernet cards:

- Enable the "Initialize Adapter Cards" feature.

- Make sure the network software drivers and programs are loaded before
  the RESUME.EXE in the AUTOEXEC.BAT.

On most networks, you should log off before turning off your computer with 
Rapid Resume.  This will make a clean break of the connection and help to 
insure proper reconnection after a Rapid Resume.




4.3 Multiple Outlet Devices (Power Strips)
------------------------------------------

If you use your computer with a switched power strip, you must turn the 
computer on and off with the On/Off button on your system unit if you want to
use the Rapid Resume feature.  After your system unit has turned off, you may
use the power strip to turn off your display and other equipment.

If you have Rapid Resume disabled or do not want to use this feature, then 
you may use the power strip switch to turn the computer on and off .
