Reset HP 17b11+

According to the manual:
To reset the calculator, hold down [CLR] while pressing the third menu key from the left. Repeat if necessary. The calculator displays
MACHINE RESET to confirm that reset has occurred.
The above sequence does not clear all memory and settings.

If you want to completely erase the continuous memory and return to default settings, press and hold down [CLR], the leftmost
menu key, and the rightmost menu key.(Press three keys simultaneously).
When the three keys are released, the calculator displays MEMORY LOST.

How to fix a none responsive button in hp 35s calculator

Resetting the Calculator
If the calculator doesn't respond to keystrokes or if it is otherwise behaving unusually, attempt to reset it. Resetting the calculator halts the current calculation and cancels program entry, digit entry, a running program, a SOLVE calculation, an ∫ FN calculation, a VIEW display, or an INPUT display. Stored data usually remain intact.

To reset the calculator, hold down the C key and press GTO . If you are unable to reset the calculator, try installing fresh batteries. If the calculator cannot be reset, or if it still fails to operate properly, you should attempt to clear memory using the special procedure described in the next section. If the calculator still does not respond to keystrokes, use a thin, pointed object to press the RESET hole.
The calculator can reset itself if it is dropped or if power is interrupted.


If the calculator fails to respond to keystrokes, and you are unable to restore operation by resetting it or changing the batteries, try the following MEMORY CLEAR procedure. These keystrokes clear all of memory, reset the calculator, and restore all format and modes to their original, default settings (shown below):
  1. Press and hold down the C key.
  2. Press and hold down the R/S key
  3. Press i (You will be holding three keys simultaneously)
  4. When you release all three keys, the display shows MEMORY CLEAR if the operation is successful.

How can I reset the calculator every time before useing it?

There are numerous procedures to reset calculations, worksheets, etc. but the most general one is to press [2nd][Reset][ENTER].
You can also perform a hard reset by pressing the Reset button in back of the calculator.
Removing the batteries has the same effect as the hard reset.
