Thanks. You were correct. I talked her through the process of removing and reseating the memory and it powered up without a hitch.

I gave my niece an A21M as a graduation gift a few years back. She called me this morning and said that it is no longer working. It hung yesterday so she did a hard power down and when she tries to restart it gives 4 evenly spaced short beeps and then shuts down. This does not correspond to the beep...
