HP-11C blinking asterisk


Hi there, my 11C is working normally, but lately an asterisk blinks constantly in the lower left corner of the display. No other ill effects that I can see; still calculates as expected. Should I be concerned?? Any way to disable it? Thanks!!


The blinking asterisk is the low battery indicator. Sooner or later you'll have to replace the batteries. After that you won't have to bother with the asterisk for atleast ten years.

(My 11C worked with its original batteries for 18 years, now I am waiting to see how long the new ones will fare)
