hdd will not recognize

I puchased an Ibm 765d laptop and was told upfront that it would need a hard drive.
So i puchased one formatted and loaded windows me in preparation,when i recieved the comp. it did not recognize the hard drive.
So i turned off re-booted pushed f1 to enter the bios,there is a box with easy setup also a box that has test so i clicked on and entered once in this box you can click on components to test,but the hdd is shaded as though it is not recognized.
All components system board,memory,display ect. all check good.I have taken this hard drive out and put in another one it boots right up any suggestion will be greatly appreciated.I am beginning to wonder if the ide connector is bad
