It has the following format: >yywwxnnnnn >Where yy+1960 is the year your hp calculator was made, and ww the week. x >is the country is was made (A=america), nnnnn is just a serial number. >I don't know if my calculator has the same problem, mine was made in 1989 >week 23 in America (number 2923A04835). Can you tell me when yours was made? >I did see the battery annunciator flash once, but that was over a week ago. > >Jeroen. the serial # is 2819A05677 so from what you say it was manufactured on the 19th week of 1988. I dont know what the cut-off date is for the defect but I suppose if your calc. is older you may be in trouble. Of course, if it is older you probably have seen the problem by now since your original batteries may be dead. -tim drury gt0297a@hydra.gatech.edu
