Calculator says ME wont work - Canon P1-DHV Calculator

when the calc is on do you see the cursor blink if it blink and no button works check maybe one of the buttons stuck if it does not blink its an hardware problem

Having received no response in over a month, I assume this is no longer a problem.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.

If that doesn't work, add a comment to this post and we'll go from there.

Having gone over a month with no response, I assume this is no longer a problem.

your value is not within the domain of the function, that is why it's giving you that error message, try the value times -1, or -(your value)

Your only hope is to reset the calculator by pressing the RESET button at the back of the calculator. Use a straightened paper clip. But if keys are physically busted you will have to contact Casio repair centers in your region.

Hello,
Check this article from the TI Knowledge Base. It addresses your question.
Hope it helps

Hello,
The ENTER button is a rather important key. You should try to have the calculator repaired.

normally if you spill any type of liquid that would certainly affect your calculator from working- i would say that you need to have it replaced

Try reinstalling the software that came with the calculator. This will fix the problem with the connection between your calculator and the computer.
