Hey all, my laptop's built-in memory card slot has been fidgety for awhile now. Sometimes I would need to insert the card multiple times before the computer would recognize that there was something in the slot. Today, I get zilch. I must have popped it out and back in 30 times. I also tried a different card to make sure that wasn't the problem. There have no new changes to the hardware or software. I am assuming that the points of contact are likely dirty. Can I safely try to clean it in any way? Or am I just better off buying a cheap USB card reader and moving along?
