Procedure 1 Functioning External FDD Check
Connect a functioning external 3.5-inch FDD to the computer's FDD port. Check the FDD
operation. If the FDD is operating properly, the user's FDD is malfunctioning. If the FDD
does not operate properly, go to Procedure 2.
Procedure 2 FDD Connection Check
Make sure the external 3.5-inch FDD cable is firmly connected to the FDD port. If this cable
is disconnected, connect it to the FDD port. If the FDD is not functioning properly, replace
the upper system board with a new one and re-start the system. If the problem still exists,
replace the lower system board.
