ΓòÉΓòÉΓòÉ 2. Extended Help ΓòÉΓòÉΓòÉ
L40 Temperature Monitor is an OS/2 Presentation Manager program for monitoring
the temperature of the IBM PS/2 L40 SX battery and the ambient temperature
inside the PS/2's case. The program will function properly only when run on IBM
PS/2 L40 SX laptop machines; on any other machine, L40 Temperature Monitor will
just show a simulated display.

ΓòÉΓòÉΓòÉ 2.1. The Display Window ΓòÉΓòÉΓòÉ
The L40 Temperature Monitor display window is composed of several elements:
1. A vertical bar graph shows the battery temperature status.
The temperature graph value ranges from 0 degrees Celsius (32 degrees
Fahrenheit) to 100 degrees Celsius (212 degrees Fahrenheit.)
This graph is updated once per second.
2. A vertical bar graph shows the PS/2 L40 ambient temperature status.
The ambient temperature sensor is attached to the rear metal case of the
PS/2 L40, and it is apparently a reading of the L40 system unit's internal
temperature. The temperature graph value ranges from 0 degrees Celsius (32
degrees Fahrenheit) to 100 degrees Celsius (212 degrees Fahrenheit.)
This graph is updated once per second.
3. A line graph records temperature values periodically, thus building a
chart of of temperature over the last hour.
A downward slope indicates that the temperature is falling, and an upward
slope indicates that the temperature is rising.
Either the battery temperature or the ambient temperature may be charted
on the line graph, and you may select which value is to be charted by
using the 'Temperature For Line Graph' option.
The temperature line graph value ranges from 0 degrees Celsius (32 degrees
Fahrenheit) to 100 degrees Celsius (212 degrees Fahrenheit.)
This graph is updated once every 18 seconds.
4. The window's program title area shows the value of whichever temperature
has been selected for charting on the line graph. This is done so that you
can minimize the program and still monitor the temperature by looking at
the minimized icon's title text.
5. When the program is minimized, the L40 Temperature Monitor program icon
shows a miniature version of the line graph.
Note: This feature is available only on OS/2 1.30.x systems.
This graph is updated once per second.
ΓòÉΓòÉΓòÉ 2.2. Temperature Limits ΓòÉΓòÉΓòÉ
Battery temperatures of 52 degrees Celsius (126 degrees Fahrenheit) and above
or 3 degrees Celsius (37 degrees Fahrenheit) and below may cause permanent
damage to your PS/2 L40 battery and/or system unit! Normally, your PS/2 L40
will go into suspend mode before the temperature exceeds these limits, but
there are ways that this protection can be overridden or disabled.
L40 Temperature Monitor will not prevent your battery temperature from
exceeding these limits, but its use may help you detect and avoid these
dangerous situations.
If your PS/2 L40 battery temperature rises to 52 degrees Celsius (126 degrees
Fahrenheit) immediately turn off your PS/2 L40 and move it to a cooler
location.
Similarly, if your PS/2 L40 battery temperature falls to 3 degrees Celsius (37
degrees Fahrenheit) immediately turn off your PS/2 L40 and move it to a warmer
location.
ΓòÉΓòÉΓòÉ 2.3. Starting The Program Minimized ΓòÉΓòÉΓòÉ
You can force L40 Temperature 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 Temperature 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 'Temperature For Line Graph' ΓòÉΓòÉΓòÉ
Select this option to be given the opportunity to choose which temperature
value, 'Battery' or 'Ambient', is to be charted on the line graph.
ΓòÉΓòÉΓòÉ 6. Help For 'Temperature Scale' ΓòÉΓòÉΓòÉ
Select this option to be given the opportunity to choose which temperature
scale, Celsius or Fahrenheit, is to be used for numerical temperature value
reports.
In the Fahrenheit temperature scale, which is used mainly in the United States,
the boiling point of water is 212 degrees and the freezing point of water is 32
degrees.
In the Celsius temperature scale, which is used internationally, the boiling
point of water is 100 degrees and the freezing point of water is 0 degrees.
ΓòÉΓòÉΓòÉ 7. Help For 'Battery Temperature Graph Color' ΓòÉΓòÉΓòÉ
Select this option to be given the opportunity to select the color to be used
for drawing the 'Battery' bar graph. The default color is red.
ΓòÉΓòÉΓòÉ 8. Help For 'Ambient Temperature Graph Color' ΓòÉΓòÉΓòÉ
Select this option to be given the opportunity to select the color to be used
for drawing the 'Ambient' bar graph. The default color is cyan.
ΓòÉΓòÉΓòÉ 9. Help For 'Window Title Updates' ΓòÉΓòÉΓòÉ
Select this option to be given the opportunity to select how frequently the
temperature 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 10. Help For 'Save Window Position' ΓòÉΓòÉΓòÉ
Select this option to be given the opportunity to save the current position of
the L40 Temperature Monitor window on the screen. The program window will
appear at this saved position each time you start L40 Temperature Monitor.
The window position data will be saved in a file named L40TEMP.INI, which will
be created in the current directory. You may, if you wish, move L40TEMP.INI to
any other directory listed in your DPATH environment variable string, and L40
Temperature Monitor will still be able to find it.
ΓòÉΓòÉΓòÉ 11. 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, the temperature
scale to be used, etc. These saved options will be used each time you start L40
Temperature Monitor.
The program options data will be saved in a file named L40TEMP.INI, which will
be created in the current directory. You may, if you wish, move L40TEMP.INI to
any other directory listed in your DPATH environment variable string, and L40
Temperature Monitor will still be able to find it.
ΓòÉΓòÉΓòÉ 12. Help For 'About' ΓòÉΓòÉΓòÉ
Use this choice to see information on the program's author, the program version
number, copyright information, etc.
