[comp.sys.handhelds] Disabling auto-power-off on a 48SX?

mjkobb@media-lab.MEDIA.MIT.EDU (Michael J Kobb) (02/22/91)

Greetings,

  I have recently discovered that Tetris, if left in Pause mode, does not
allow the calculator to turn itself off (discovered that this morning....
:-().  Is this because it's constantly executing a loop of some kind, so the
calc thinks it's active, or is it setting a flag or something?

  Is there any way to make sure that the calc will shut itself off, besides
adding a check in the Tetris code that just shuts if off after, say 15-30
mins?

  Email's fine.  I'll summarize if people care.

The HP won't shut-down if it's running a program unless it's specifically
waiting for a keypress or is otherwise halted (input, 0 or -1 wait, halt,
prompt, etc.).  It states specifically in the manual not to leave
applications running for long periods of time to prevent excessive
battery drainage.  Of course, for Tetris, if you pause it, go to the
pause routine, if the calc is paused for more than a few minutes, then
execute the "off" yourself--otherwise, it would seem that the user wants
to play the game.  Even if the user left the program running, it would
end the game.  Now, my only question is: Will the HP autoshutoff while in
the graphics environment?  I think it probably will, but I'm not sure.

If you have the newest version of Tetris, or you can just add it
yourself.  Just press O to turn it off.  When you turn it back on, it
continures from where it left off.
