Purchased the 15 inch MacBook pro about 9 months back and recently got the high speed wireless card (Sprint ExpressCard EVDO - EX720). It was working the first few times I used it. I had remove the card this morning from the slot and now it wont stay in. Card still works as long as I hold it in with one hand. But one hand computing is not very fun or comfortable. Went to the Apple store and tried to see if it was the card or the MacBook. Inserted the card and it locked in like it should on the MacBook Pro at the store. I was told I would need to leave my computer with them for 5 days so they could check it out. Told them I need to come back later to drop it off. Did anyone else have this problem?
