49g memory dump Message #1 Posted by Troy on 3 Mar 2004, 12:35 p.m. Moments ago, I was saving formulas in my 49 when I got an error saying 'Insufficient memory'. Then the screen went blank and it beeped whenever I pushed any bottons. I was locked out so I removed the batteries. It then asked if I wanted to recover the memory, I said yes. After a few moments everything was gone. Can anybody help? I had over a year's worth of work and class-related items saved and now they are gone.

Re: 49g memory dump Message #2 Posted by James M. Prange on 3 Mar 2004, 5:22 p.m., in response to message #1 by Troy Sorry, I very much doubt that there's any way to recover anything that you had in the home dirrectory, port 0, or port 1 and wasn't backed up elsewhere, although port 2 is non-volatile and anything that you had there should still be there. I don't know what caused the problem, but if it happens again, try a keyboard warmstart (ON and F3 together), and if that doesn't work, force a warmstart with a paperclip in the reset hole in the back. (no, a hardware reset doesn't clear your variables). Remove the batteries only as the very last resort, or if you really do want to completely clear the home directory and ports 0 and 1. From now on, back up the home directory, port 0, and port 1 to flash (port 2) occasionally. Also do some backups of everything that you really want and can't get elsewhere to a PC, because your calculator can fail, be lost, stolen, or destroyed. By the way, be sure to use the latest ROM, version 1.19-6, available at http://etud.epita.fr/~avenar_j/hp/49.html; it has a reputation of being more stable, and certainly has some nice enhancements and several bug fixes. Regards, James
