Hi,

 

There could be several reasons for this:

 

1) If you have just purchased the calculator and inserted the batteries for the first time:

It could be a manufacturing defect interrupts the battery contact when you close the lid.

Call HP support for a replacement.

 

2) If you have used it for a while and are replacing the batteries:

Ensure you have the right size batteries.

If it uses 2 x CR2032 coin cells, ensure they are fitted correctly (both  +ve visible).

 

3) If the calculator turns off unexpectedly (especially when pressing a button):

Replace the batteries.

 

 

Hope this helps.

 

-Bart

Hi!, @fcobo220:

 

Try, too, clean with pharmaceutical alcohol (99%) and cotton, without dust, the contacts from the allocated batteries and poles of batteries.

 

Check, with tester, the battery have, 1.5VDC, of any brand, what, your purchase and that use, your HP12C .
