- ΓòÉΓòÉΓòÉ 2. Extended Help ΓòÉΓòÉΓòÉ
-
- L40 Battery Monitor is an OS/2 Presentation Manager program for monitoring the
- condition of the IBM PS/2 L40 SX battery. The program will function properly
- only when run on IBM PS/2 L40 SX laptop machines; on any other machine, L40
- Battery Monitor will just show a simulated display.
-

-
- ΓòÉΓòÉΓòÉ 2.1. The Display Window ΓòÉΓòÉΓòÉ
-
- The L40 Battery Monitor display window is composed of several elements:
-
- 1. A vertical bar graph shows the battery voltage status.
-
- The voltage graph value ranges from 15 volts, the maximum voltage that can
- be supplied by the PS/2 L40 AC adapter, down to 9 volts, the minimum
- voltage that the battery can safely supply.
-
- A freshly charged PS/2 L40 battery will have an initial voltage graph
- value of somewhere between 11.5 volts and 13.5 volts, depending on the age
- of the battery, the battery temperature, etc. This value will decrease as
- the battery is discharged, and the PS/2 L40 will enter suspend mode when
- the voltage value falls to about 9 volts.
-
- The voltage graph value will increase when the battery is being charged.
-
- This graph is updated once per second.
-
- 2. A vertical bar graph shows the electrical current (in amperes) being drawn
- from the battery.
-
- The current graph value ranges from 0 amperes to 4 amperes during normal
- operation on battery power, and this indicates that the battery is being
- discharged. Higher current graph values indicate higher rates of battery
- discharge.
-
- The current graph value ranges from 0 amperes to -1 amperes when the PS/2
- L40's battery is being charged.
-
- This graph is updated once per second.
-
- 3. A line graph records the voltage value periodically, thus building a chart
- of battery voltage over the last hour.
-
- A downward slope indicates that the battery is discharging, and an upward
- slope indicates that the battery is charging. The line graph values range
- from 15 volts down to 9 volts.
-
- This graph is updated once every 18 seconds.
-
- 4. An indicator above the line graph appears whenever the PS/2 L40 AC adapter
- is attached.
-
- 5. The window's program title area shows the value of the battery voltage.
- This is done so that you can minimize the program and still monitor the
- voltage by looking at the minimized icon's title text.
-
- 6. When the program is minimized, the L40 Battery Monitor program icon shows
- a miniature version of the line graph and a 'dot' that appears whenever
- the PS/2 L40 AC adapter is attached.
-
- Note: This feature is available only on OS/2 1.30.x systems.
-
- This graph is updated once per second.
-
-
- ΓòÉΓòÉΓòÉ 2.2. Voltage Limits ΓòÉΓòÉΓòÉ
-
- Voltages of 9 volts and below may cause permanent damage to your PS/2 L40
- battery! Normally, your PS/2 L40 will go into suspend mode before the battery
- voltage falls this low, but there are ways that this protection can be
- overridden or disabled.
-
- L40 Battery Monitor will not prevent your voltage from falling below 9 volts,
- but its use may help you detect and avoid these dangerous situations.
-
- If your PS/2 L40 battery voltage falls to 9 volts or less, immediately turn off
- your PS/2 L40 and/or connect the PS/2 L40 AC adapter.
-
-
- ΓòÉΓòÉΓòÉ 2.3. Starting The Program Minimized ΓòÉΓòÉΓòÉ
-
- You can force L40 Battery Monitor to start up in the minimized state (that is,
- as an icon rather than an open window) by specifying the /M parameter when
- starting the program. This is the only command-line parameter that the program
- accepts.
-
-
- ΓòÉΓòÉΓòÉ 2.4. Getting Rid Of The Logo Window ΓòÉΓòÉΓòÉ
-
- L40 Battery Monitor consults your OS/2 system configuration parameters to
- determine how long it should display its initial logo window. After you install
- OS/2, the logo window display time is 'indefinite', and you must press ENTER to
- dismiss the window. You may change the logo window display time to any desired
- value in milliseconds, including 0, in one of the following ways:
-
- o Under OS/2 PM 1.3, bring up the Desktop Manager menu and select the "Group -
- Utilities" option. Under this menu, select the Control Panel application.
- The logo display time value can be changed via an action bar menu item.
-
- o Under OS/2 PM 2.0 with the Workplace Shell (WPS), open the "OS/2 System"
- folder on the desktop. Under this folder, open the "System Setup" folder,
- and select the System icon under this folder. The logo display time value
- can be changed via one of the notebook 'tabs'.
-
-
- ΓòÉΓòÉΓòÉ 3. Help For 'New' ΓòÉΓòÉΓòÉ
-
- Selecting this menu option will cause the line graph display to be erased. A
- new graph will be started.
-
-
- ΓòÉΓòÉΓòÉ 4. Help For 'Exit' ΓòÉΓòÉΓòÉ
-
- Selecting this menu option will end the program.
-
-
- ΓòÉΓòÉΓòÉ 5. Help For 'Volts Graph Color' ΓòÉΓòÉΓòÉ
-
- Select this option to be given the opportunity to select the color to be used
- for drawing the 'Volts' bar graph and the line graph. The default color is red.
-
-
- ΓòÉΓòÉΓòÉ 6. Help For 'Amperes Graph Color' ΓòÉΓòÉΓòÉ
-
- Select this option to be given the opportunity to select the color to be used
- for drawing the 'Amps' bar graph. The default color is cyan.
-
-
- ΓòÉΓòÉΓòÉ 7. Help For 'Window Title Updates' ΓòÉΓòÉΓòÉ
-
- Select this option to be given the opportunity to select how frequently the
- voltage value displayed in the program window title bar is to be updated. By
- default, the window title value is updated each time the line graph is updated.
-
-
- ΓòÉΓòÉΓòÉ 8. Help For 'Save Window Position' ΓòÉΓòÉΓòÉ
-
- Select this option to be given the opportunity to save the current position of
- the L40 Battery Monitor window on the screen. The program window will appear at
- this saved position each time you start L40 Battery Monitor.
-
- The window position data will be saved in a file named L40BATT.INI, which will
- be created in the current directory. You may, if you wish, move L40BATT.INI to
- any other directory listed in your DPATH environment variable string, and L40
- Battery Monitor will still be able to find it.
-
-
- ΓòÉΓòÉΓòÉ 9. Help For 'Save Program Options' ΓòÉΓòÉΓòÉ
-
- Select this option to be given the opportunity to save your current program
- option selections, such as your selection of graph colors. These saved options
- will be used each time you start L40 Battery Monitor.
-
- The program options data will be saved in a file named L40BATT.INI, which will
- be created in the current directory. You may, if you wish, move L40BATT.INI to
- any other directory listed in your DPATH environment variable string, and L40
- Battery Monitor will still be able to find it.
-
-
- ΓòÉΓòÉΓòÉ 10. Help For 'About' ΓòÉΓòÉΓòÉ

- Use this choice to see information on the program's author, the program version
- number, copyright information, etc.
