Isn't OFF supposed to automatically include CLOSEIO? Shouldn't removing a battery without turning OFF also turn itself off anyway? (IIRC, battery removal can even substitute for a reset, such as during ROM update) -[ ]-

If you have a multimeter, maybe you can measure the voltage of the batteries when they're freshly charged, at the low battery warning, and then when it won't turn on any more. That should give us a good idea of what's going on. You can also make an electric current measurement (remember the meter goes in series with the batteries, not in parallel). You can compare your measurement to measurements made by Eric Rechlin in his August 17, 2007 message to this forum: http://groups.google.com/group/comp.sys.hp48/browse_thread/thread/6dec4019c34f9786/0ee8dda15d53072a?lnk=gst Good luck, -Jonathan |
