Question about Texas Instruments TI-89 Calculator
Hi, i have this problem I have not used my ti89 for a winter, winter break..u know fun times, no hw...and then when school starts again, i use my ti89 again, and all a sudden the button 5, 6 and x..is not working. Is there anyway to fix this? the warranty is already expired =(
SEND IT INTO Ti, LET THEM CECK IT OUT, FOR A SMALL FEE IT'S WELL WORTH IT.
IT'S BETTER THAN BUYING A NEW ONE, PLUS THAY WILL
FIND THE PROBLEM AND INTSTALL THE LATEST VERSION SOFTWARE IF NEEDED TO BRING IT UP TO LATEST CONFIG, AS THAY DID TO MINE.
