The decimal, 2, 5, 8, (, and the cos button are not working on the calculator. I let my brother borrow it and when i got it back it worked fine. I havent used it in a few weeks. Ive done everything the other forums say to do, and it still isnt fixing it. I reset the whole thing, reset with the button on the back, etc etc. Please help i have my act tomorrow and need a calculator for my math class.
This sounds a lot like a hardware problem with a circuit that’s broken for that key column. Unfortunately, I don’t know how to help you fix the issue from the hardware side and from the information I gathered I don’t think you’ll be able to fix any hardware issues before your ACT. However, MateoConLechuga may have away to fix it through software Press [prgm] (If that button doesn’t work leave a reply and I’ll describe how to do it another way)Scroll to the right over to ‘NEW’ and press [enter]Type in the letter A and press [enter] againPress [2nd]>[0] and scroll down to Asm84CEPrgm (If this is crossed out in blue, leave a reply and I’ll describe how to do it another way)Press [enter]Now type in EXACTLY the following characters (they should be on the same line as the Asm84CEPrgm token)210100F53678C9Press [2nd]>[mode]Press [2nd]>[0] and scroll down to Asm( and press [enter]Press [prgm]Press [enter] on program AYour screen should look like Asm(prgmA Press [enter]If it just says ‘Done’ then it should have worked. Try the buttons again and let me know if they work again! Since your calculator may not be reliable, I think your best bet is to see if your ACT proctor has a spare calculator or if some student brought along a spare. If there’s no spares, then just know that most commands and operations you need are available in the catalogue (which you access by pressing [2nd]>[0]).
