In my X51v I inserted one SD card for another and as I inserted the SD card, it felt as if there was a spring loading pushing it out - hence it won't seat all the way down. I've inserted SD cards many times, so I know it was facing correctly sliding down its grooves on the side. I can't see any of the 5 or 6 pins that might be bent, they are all oriented the same.
Is there some trigger or blocking tab in there because I see a little black tab extending form the side in the cavity slot where the pins are.
Any help would be appreciate.
