No power. Batteries are new and test as charged.

Hello :

It seems that the base where batteries set is rusty or dirty . Clean it and try again . If that didn't solve the problem , then it must be something serious . You need to take it for repairing to solve the problem .

good luck .

What does error #13 dimension mean on my TI-86 calculator, please.

Three possibilities:

1) You entered an argument with an inappropriate dimension.

2) You entered a matrix or vector dimension < 1 or > 255 or a noninteger.

3) You attempted to invert a matrix that is not a square matrix.

If you need further help, please specify the exact problem you're trying to solve.
