Question about Texas Instruments TI-89 Calculator
The two are probable related- when I power on my calculator after a hard reset without batteries or backup battery, the alpha function turns on and stays stuck on unless I hold down the alpha key. When I try to turn it off, it turns back on after about half of a second. I tried the 2nd-L-R-On reset, blew off any dust that may have been on the i/o ports and still haven't had any luck. Does anyone have any ideas?
Same problem here, that auto-program, is not worked, please help

Auto-off is to turn off the alpha button when you enter into a program that only uses numbers. It's a safe asm program and download the one that says, ".89z" to your calculator. I guess it will work or not. Remember where you got that program in case you need to uninstall it. I actually think you'll like it. Just have it real close so you can run it when you need to. If you have hardware 2 make sure you download h220xtsr too.
I tried to figure a way to help you with a simple function, I'll let you know if I come up with any ideas.
