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.

My HP 48GX just displays a black (all pixel) display screen with one vertical stripe down the middle. I tried reset button and now it displays 2 vertical stripes (the new one divides the right half in...

I just had this exact problem so I reset the memory as instructed below. Know I am back in business. Memory reset A memory reset will return the HP 48 to its factory-default state, which will erase all stored user memory. Use this feature very carefully.
  1. If necessary, turn the calculator on.
  2. Press and hold the ON+A+F keys simultaneously.
  3. Release all three keys at the same time. This should cause the calculator to display the message "Try to recover memory?"
  4. Press the A key to attempt to recover memory or the F key to erase the user memory. When A is pressed, occasionally the objects in memory are recovered in new sub-directories of HOME labeled D.01, D.02, et cetera, although there is no guarantee that all of the variables will be recovered. Pressing the F key will cause all information stored by the user to be erased from calculator memory. This will also affect any RAM card that is merged with main memory. If the card is not merged or it is write-protected, it will not be affected by this reset.
Hardware symptoms and solutions I. The display screen has a blue/purple blotch of color, even when the unit is off The screen is damaged, and the calculator requires service. Please contact HP . II. All of the pixels on the screen are lit (blue)
  1. Try to adjust the contrast by holding down the ON key and repeatedly pressing the [ - ] key.
  2. If the screen is still dark, try to halt the system using the keyboard.
  3. If this does not correct the problem, try to reset the system using the reset hole with the batteries removed.
  4. If this does not work, remove the batteries and let the unit sit for 48 hours. After 48 hours, replace the batteries. If the problem persists, attempt a memory reset. Although removing the batteries for 48 hours should erase the user memory, performing a memory reset will ensure that the calculator is reset to its factory defaults.
  5. If the problem persists, the unit requires service. Please contact HP .

Hi, are there MC, MR, M-, M+ functions in Texas Instruments BA II Plus calculator?

The calculator has 10 memories (0 to 9)
To store a number (13) in memory 6 type 13 [STO] 6
To erase the content of memory 6 (M6) store 0 in int: 0 [STO] 6
To recall the content of memory location M7 press [RCL]7

To operate on the content of memory location M5 the syntax is [STO] [Op] 5, where [Op] is the operation symbol [+], [-],[x], [/] [y^x]

Ex: to raise the content of memory location 4 to the power of the displayed value, you press [STO][Y^x] 4

To clear all 10 memory locations
press [2nd][MEM][2nd][CLR WORK]

In short, although you do not have the keys you are accustomed to, you have a lot more. And please do not blame me if you feel disappointed.

It calculator tells you Ram Cleared each time you turn it on, the most likely reason is that the backup battery is depleted. Its role is to keep the memory modules electrically refreshed when calculator is turned off. If the backup battery is dead, the memory is erased when you turn calculator OFF. Main batteries no longer supply power and the contents of the memory are cleared.
  1. Check that main batteries are good and inserted in calculator.
  2. Turn calculator OFF.
  3. Replace the backup battery.
  4. Turn calculator ON.
  5. Press the [CLEAR] key to erase the "Ram Cleared" message.

Why won't my calculator type it's just the screen and the marker. won't even turn off by itself just on and does nothing.

If cursor is a checkerboard rectangle that means the memory is full. Memory must be cleared or at least some space freed.
Press [2nd] [MEM][7:Reset][1:All Ram][Reset].
Press [CLEAR] to erase Ram cleared message.

If some third-party program or game is stuck in memory, it should be kicked out of memory.

I can't get the memory function to work and/or erase the memory icons(M1,M2,M3)

I think there is something wrong with the calculator. Mine will not allow memory recall either. Maybe I lost the magic words to allow this function to work
