Solution 11883: Graphing Calculator Seems to Slow Down When the TI Connectivity Cable is Inserted.
Why does my graphing calculator seem to slow down when the TI connectivity cable is attached?
If the TI Connectivity cable is not completely inserted into the I/O port, it can cause the graphing calculator to appear to "slow down". The graphing calculator will usually respond to keys but just very slowly. Try inserting the cable more firmly in the graphing calculator's I/O port.
