I changed the batteries, and the calculator went dead.

Hello,
.
You can reset the calculator:
Turn the back of the calculator towards you. Extract the top left
rubber pad on the back of the calculator and use a paper clip to press
the Reset button. If that does not restore the calculator to health,
you should perform the dagnostic tests.
The following procedure valid for the 48G should work for the HP48GX.
Make the calculator perform a
Self test.
It tests the RAM and ROM. You will see various patterns on screen. Afterwards you should see
IROM OK,
IRAM OK,
HP48GX OK
The self test will continue repeatedly until you perform a
System Halt
The empty stack should appear.
If you do not see IROM OK and IRAM OK, the calculator requires service.
If the above procedure is successful, you may want
to test the keyboard.
To exit the keyboard test proceed as described above under System Halt.
If you follow the proper sequence and a hexadecimal number appears after pressing a key, the calculator requires service.
Hope it helps.
