I used to have that problem. It only seemed to occur when I had the SRAM card
plugged in. I am not an expert, but I do know that if the card is in, if the
alarm goes off, it first has to wake up the card. This may take longer than the
process and the alarm is missed.
It may also be due to closing the appointment application and deleting its state
file (such as in a soft boot). The Geos OS has to restart the app when the
alarm goes off, or maybe it misses the alarm completely because of the deleted
state file. This is just a guess, but the alarm problem has not re-occured
since I made a practice of always taking the SRAM card out and I never soft boot
the Ogo unless I absolutely have to.
Anyone else?
