    What happens if you remove the batteries, put them back in, and turn the calculator on? If that does nothing, remove and replace the batteries again, then hold down the - key while pressing the ON key to turn the calculator back on. Does that do anything?

Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Hello,
Here is the self-test procedure for your calculator. If it does not answer as it should, it may need service. Sorry, I resized the picture but FixYa refuses the new dimensions. Hope it helps.

How to calculate mortgage pmt using hp. I cannot remember the sequence


There is an excellent computer-based tutorial for the HP 12c Platinum on HP's website (although the sequence for TVM calculations is the same for the original 12c).
Download it and have a look. It will guide you key-by-key through the steps.

Frozen Screen


If you can locate an external USB mouse/keyboard or Wireless set; try that and see if this fixes the problem. If your computer works with the external hardware, go to the HP web site and download new or current drivers and install them accordingly. If after the installation and removal of external hardware it still hangs up; the keypad may defective or other issues requiring professional servicing.

Do you have advice in calculator choice between HP 12 c and the TI BA II Plus Professional Financial Calculator? Assuming that I get proficient with RPN (which I'm learning now); is one faster than the...


The 12C is more expensive and more powerful than the BAII+Pro. The HP is also programmable, which the TI isn't. Starting from scratch (assuming you've never used a calculator before---a somewhat unreasonable assumption) the TI might be easier to learn, at least initially. But after a certain point, the HP will leave the TI behind. The HP is faster and more capable.

There are at least three different versions of the 12C available. There's the original 12C, the 12C Platinum, and the current 12C. The only way to tell the difference between the two non-Platinums is to look at the battery compartment---the original uses three button cells while the newer uses two coin cells. The newer one is MUCH faster. The Platinum, however, can use RPN or algebraic.

Unless your choice is limited to the 12C or the BAII (by the requirement of an exam, perhaps), you might want to look at the HP 20B and the HP 30B. Programmability aside, they're even more powerful and easier to use and faster than the 12C, and the 30B is also programmable.

There are other considerations, of course. Factors such as the feel of the keyboard, the 12C's landscape orientation as opposed to the others' portrait orientation, etc, are all matters of personal preference.

Disclaimer: I own multiple HP and multiple TI calculators. I tend to use HP calculators for calculating, while I use TI calculators to answer questions here at FixYa.

I couldn't find any reference to a HP calculator model 12p.
There is a HP 12c financial calculator and a 12c Platinum financial calculator.
Check both models (for images, specifications, functions, user guides, etc.) :
