In any scientific calculator log2(n) can be calculated with either ln or log function as
Log2(n)= ln(n) / ln(2)
Log2(n)=log(n) / log(2)
both will give nearly the same answers

I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.
Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.
Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.
Hope it helps.

Testimonial: "Thanks so much, its working now:) I thought I was going to have to buy a new calculator!"
I am afraid but your question does not make sense to me. These are are two different calculators. What do you mean by change? Is it the same as in fairy tales where a prince is changed into a frog?
