I have upgraded many Dell Inspiron 1545/1525 to SSD drives. It can be quite difficult to get the 7mm SSD to meet the SATA connection due to the angle it is at in the old 9mm space. Fold a piece of A4 paper twice length ways and then make three or four 2cm folds to create one fatter end. Place the fatter end on the keyboard side of drive and slide both in. Then pull out the paper whilst holding the drive seated and voilà. You could attempt this with any notebooks which have side loaded hard drives. Good luck
