URGENT HELP WITH CAS REQUIRED

[BlueSky_3]

I entered a polynomial equation with two unknown variables and typed solved for which the equation is < 8000 into my TI-89
and now its is stuck for 30 mins during a trial exam aswell 

Does anyone know how to unfreeze it without deleting the applications?

[alypew]

I'm not sure about the TI-89, but I have the nspire and I just press the 'on' button.

[BlueSky_3]

Yeah I tried that but it didn't work.

EDIT: It's now been 2 hours and 15 mins and counting until it last froze.

Any help would be profoundly appreciated.

Take the batteries out LOL!

[BlueSky_3]

Tried that 

EDIT: total time frozen is 3 hours and 19 mins and counting.

Anyone know how to unfreeze it please?

Oh you have to take your batteries out, take a screw driver, undo the screw near the top of the battery compartment to take out the backup battery as well, if that's taken out, leave it for a minute, and put everything back in

[paulsterio]

Or if that doesn't work, you'll have to do a hard reset, so put everything back in place - get someone to help you out here, what you need to do is hold down these 4 buttons holding down LEFT, RIGHT, 2ND and ON as you (or someone else) puts the last battery into the calculator

[SamiJ]

Is there a reset button like on the nspires?
