- WHAT IS GasGauge?
-
- GasGauge is a 10K TSR, battery timer for Laptop computers with an integrated in
- LARGE BLOCK CURSOR option. GasGauge displays an estimate of how much battery
- time is left on your laptop computer before a battery charge will be needed.
- On-Line Magazine (p.23, April 1989) called GasGauge "one of the most popular
- files accessed on the PC Board".
-
-
- STARTING GasGauge:
-
- Usage: GG drive [/C /A /U /O=xx|ttt]
-
- drive is the disk drive from which your laptop computer starts.
-
- GasGauge writes a very small file named "GAS" in the root directory of your
- boot disk. GasGauge uses this "\GAS" file to deterimine the last day and time
- that you used your laptop computer how much time is remaining since your last
- session (and battery charge).
-
- * If you are using a laptop with a hard drive type "GG C"
-
- * If you are using a laptop with only floppy drive type "GG A"
-
-
- IF YOU BOOT WITH A FLOPPY DISK:
-
- 1) You must always start the computer with the same boot diskette. This is
- because the file "A:\GAS" must be read on power-up to get the cumulative
- elapsed time from your last session.
-
- 2) You must always end your work session with the same boot diskette to update
- the "A:\GAS" file for the next session. Very simply, follow these steps:
-
- a) Re-insert the original boot diskette in the "A:" drive.
-
- b) Press [ALT][LEFT SHIFT] to toggle the screen and update the elapsed
- time.
-
- c) The current elapsed time "\GAS" file will be written to the boot disk.
-
- d) Switch off the laptop computer.
-
- 3) There must always be a diskette in the "A:" drive because GasGauge tries to
- update the "A:\GAS" file continuously, once every minute. The diskette in
- the "A:" drive doesn't necessarily have to be your boot diskette. GasGauge
- will write a very small, 8 byte file to whatever diskette is in the "A:"
- drive. Just remember that "A:\GAS" file on the original boot diskette must
- be reinserted at the end of your work session to be updated before you
- switch off your computer.
-
- Once GasGauge has started, estimated "remaining-time" will be displayed in the
- upper right corner of the display. If you have a registered copy of GasGauge,
- you can toggle the display to the upper left corner and off completely by
- holding the [ALT] key then pressing the [LEFT SHIFT]. [ALT][LEFT SHIFT] will
- also force an immediate save of the current elapsed time on the boot disk on
- both the registered and shareware versions of GasGauge.
-
-
- /A ALARM (registered version only)
-
- If the ALARM is on, you will be warned audibly when the battery life is
- dangerously low. The alarm can be heard regardless of what you are doing with
- the computer and will sound without having to "pop-up" the GasGauge. When the
- Alarm is on, an "a" will appear to the right of the time display.
-
- /O=xx|ttt OFF LIFE (registered version only)
-
- where 'xx' the number of days your battery will stay charged when the computer
- is off and not connected to your A/C charger. where 'ttt' are the maximum
- minutes of use that you can get from a full charge.
-
- This "off-life" value is difficult to estimate and can more easily be found in
- your laptop computer manual.
-
- Consider the following example:
-
- Your computer operates for 240 minutes on a full charge (the
- BATTERY LIFE is 240 minutes) but your computer only stays charged
- for 14 days if it is unplugged and not used (so the OFF LIFE is 14
- days).
-
- Assume that GasGauge was reset to 240 the last time the battery
- was charged and the charger was disconnected.
-
- After 7 days of not being used GasGauge knows that 50% of
- the battery life was consumed (50% = 7/14 days) while the computer
- was not used.
-
- The elapsed time will be increased by 50% and the GasGauge
- will show 02:00 remaining (120 minutes = 50% x 240 minutes from a
- full charge).
-
- The DATE and TIME must be correct on your computer for the
- OFF LIFE to work correctly.
-
- /C CURSOR - Large block cursor (registered version only)
-
- The CURSOR option changes your flat sissy cursor into a big plump block cursor.
- A small stand alone program named "CURSOR.COM" can be used without GasGauge and
- consumes only about 2K when resident.
-
-
- GasGauge INCOMPATIBILITIES
-
- The "Remaining-time" display will not appear on graphics screens. However,
- GasGauge does continue to work in the background and the elapsed time file will
- continuously be updated. The display will reappear after you exit the graphics
- screen.
-
- Some Microsoft programs do not follow rules for interrupt service routines
- handling keyboard input. (Technically, the driver does not enable interrupts
- before invoking the original keyboard interrupt handler.) Because of this, the
- small version of GasGauge will not work with QuickBasic 4.50, QBX 7.x, and
- some other Microsoft programs.
-
-
- RESETTING THE GasGauge AFTER EACH BATTERY CHARGE
-
- Each time you fully charge your laptop batteries, you must tell GasGauge that
- the batteries have been recharged. To reset the remaining time, start GasGauge
- then hold down the [ALT] key and press [\]. A prompt will appear in the upper
- right corner of the display. Type the estimated amount of time (in minutes)
- that you expect to get from your fully charged battery.
-
- Here is how to estimate the battery life of your laptop computer:
-
- 1) First charge the battery fully then remove the battery
- charger.
-
- 2) Start GasGauge using "GG C" or "CC A"
-
- 3) Press [ALT][\] and reset the elapsed time to "0"
-
- 4) Leave the computer on until the battery is completely
- discharged.
-
- 5) Plug the computer in and start GasGauge. The negative number that appears
- in the upper right corner will be the time expected from a fully charged
- battery. Remember, GasGauge requires the BATTERY LIFE in minutes so 3 hours
- and 15 minutes would be typed as 195 minutes.
-
-
-
- TECH SUPPORT:
-
- When requesting technical support please report the following:
- 1) Memory before running the program (use the dos command "CHKDSK:)
- 2) The names of any TSR memory resident programs (Sidekick, Prokey..)
- 3) A listing of both your AUTOEXEC.BAT and CONFIG.SYS files.
-
-
- DEEP DISCHARGE "DEEPDIS.COM" PROGRAM (registered version only):
-
- The GASGAUGE deep discharge program depletes your battery more quickly by
- running all power consuming devices continuously until the battery is
- discharged. To start the Discharge program type "DEEPDIS"
-
- Some manufacturers recommend a complete discharge of rechargeable batteries to
- exercise the battery for maximum charge time. Batteries which are not fully
- discharged before being recharged can develop 'recharge memory' which can
- result in a shorter 'charge life'.
-
- To avoid premature wear on your disk drives you should only use this program
- when you would like to discharge your batteries as quickly as possible.
- Although the Deep Discharge program has been tested on a variety of computers
- you should contact your computer manufacturer if you have any questions about
- continuous disk drive operation.
-
- Before starting the deep discharge routine all external disk drives should be
- off or disconnected and diskettes should be removed from the drives. The
- GasGauge elapsed time file will not be updated so remember to reset the elapsed
- time after recharging the batteries.
-
- The deep discharge program may be stopped by pressing the [ESC] key. There may
- be up to a ten second delay before the disk drives stop turning
-
