Question about HP 17bII Calculator
Recently my trusty HP 17BII has stopped working correctly when I try to add a number to another number. If I push the "+" key several times, I can usually coax the calculator to do the calculation. Has anyone experienced this issue and, if so, is there any known fix? In fact, I just realized that the addition and subtraction keys are both behaving this way. Multiplication, division, exponentiation, etc. all seem to work as expected.
Do a self test
1. Turn the calculator on.
2. If you have the optional infrared printer, turn it on. Certain diagnostic
information is printed during the test.
3. If possible, return to the MAIN menu (press @A).
4. To start the self-test, hold down C while you press the fifth menu
key from the left. Once the self-test has begun, do not press any keys
until you are ready to halt the test.
5. During the test, the calculator beeps periodically and displays various
patterns and characters. Watch for one of two messages that are
displayed before the test automatically repeats:
If the calculator passes the self-test, the calculator displays
If the calculator displays followed by a five-digit number,
the calculator requires service.
6. To halt the self-test, hold down C while you press the third menu
key from the left. The calculator displays . If you
press any other key instead, the test halts and the calculator displays
a message. This results from an incorrect key being pressed,
and does not mean that the calculator requires service.
7. If the calculator failed the self-test, repeat steps 4 through 6 to verify
the results. If you do not have a printer, write down the messages that
are displayed in step 5.

If you have and error code on a fail test you need to contact HP to find out what it is. If the self test worked you should get and ok message. This is probably related as to why the + key isn't working.

Hi and welcome to FixYa,
Initially and based on your description, faulty keys, or to be more specific, the "+" and "-" contacts underneath the pad are fault or perhaps just dirty. it would be a matter of opening the unit and peforming a clean of the keypad. Not unless the unit has been dropped, then possibility of a defective component of a broken flat cable is small.
Good luck and Thank you for using FixYa.

Swap out your keyboard and see if it goes away, never over react to these things, you may finf that it has nothing to do with what you first thought. It may be as simple as a ne variant of a worm or virus that attacks certain keys or combination there of. First try running a good virus/malware program, you may getone here,http://www.avg.com/, there is a free version on the site, try running that first, once we eliminate a software issue, we may concentrate on the obvious. Thanks Gym
