I've replaced the batteries with brand new ones (both the AAA's and the circle one) and it wont turn on.

It didn't suddenly just stop working ,it told me i had to put new batteries in but i couldnt be bothered but then it eventually just didnt turn on again.

I have C3 and C4 in 2 weeks..I can't afford a new one..what do i do? Any advice on how to get it up and running again?

p.s i have tried fiddling with the contrast.

Sometimes after removing the back up battery (button one) you have to hit the reset button for it to then turn on. If this fails you could either try and cope with a scientific or borrow one for the exams. Im sure your teacher would allow you to borrow a graphic one for the exam no?

I think i could find one to do the exam with but I need it to work for revision!

Plus it has some resale value if it actually works it was bloody expensive

Any other tips to get it on again? Only had it 18 months i see no reason why it should be kaput

i always found with my calculator, as did everyone else at school about 30 mins into GCSE maths exam (it musta been the calcs they gave us all in year 9...) that a firm smack on the table would get it going again.

Worth a try!

Well, what do you expect?

If there's a reset button, try that. Or find the instructions and see if there's anything in there to help troubleshoot.

I expected to be able to put new batteries in it when they run out and for it to turn on again :P

Thanks for tips so far guys, none of them have done the trick as of yet ;(

that calculator is far more useful than i thought, zack showed me how to do the integral area thing, its so helpful as a check for c4. apparently you can do it for volumes of revolution too, but i'm not sure how.

Volume of revolution is just the same really

Area under the curve xsquared between 0 and 1 :
fnInt( x^2, x, 0, 1 )

Volume of revolution of curve xsquared between 0 and 1:
fnInt( pi(x^2)^2, x, 0, 1 )

So the only difference is you replace what y equals with .. pi times (what y equals, squared.)
