Enter the above exactly as it appears, including the blank line. End each line
by pressing the <Enter> key. Then at the DOS prompt enter the command
DEBUG <NUMOFF.SCR. This will pipe the script file to DEBUG which will
create the program NUMOFF.COM. Then all you need to do is include
NUMOFF in your AUTOEXEC.BAT file.
POWER SAVE FEATURES
Q27. Are there any special power saving features to help prolong battery life?
A27. Yes. In SETUP, there are two power save options: Standby timeout and Hard
disk timeout. Standby timeout lets you set the elapsed time (from 1 to 63
minutes) between keystrokes before the NB3s goes to power save mode.
This mode shuts off the LCD backlight, slows the CPU speed down to 8 MHz
and turns off the display. You return to normal operation by pressing any
key. Note that this mode is active only when running from the battery; if
you’re using AC power, this mode is disabled.
The Hard disk timeout lets you define the elapsed time (from 1 to 18 minutes)
before the hard drive powers itself down. If there is no drive access within the
timeout period, the hard drive parks the read/write heads and powers the
drive down. The next time a drive access is requested, the hard drive powers
back up. Be patient, as it can take up to 15 seconds for the hard drive to
reach the correct operating speed. Remember that frequent drive start-ups
can consume more power than the mode saves and can cause needless
wear to the drive. Start with a timeout value of 5 minutes and adjust it
accordingly.
Note that these settings should be disabled for operating systems other than
MS-DOS, as they may access these resources in a totally different manner.
Finally, there is the manual power save button, located directly above the
power switch. When running from battery and this button is pressed, the
computer turns off the LCD backlight and disables the display; parks the hard
drive read/write heads and powers the drive down; disables the keyboard and
stops all processing by the CPU. If you are accessing any disk drive at the
time, the access is completed before the power save mode is enabled. The
CPU speed on the LCD status bar blinks and shows 0.0 MHz. To resume
normal operations, simply press the power save button again.
