Transcend MicroSD card adapter will not work when plugged into laptop

I've been trying to use my MicroSD card adapter in my laptop's SD card slot, but it won't even read or recognize that it is there. I've tried and external SD reader and that won't work either.
 
We had this same problem, with "high endurance" TF/SD card adapters. We found that these adapters are mechanically off-size, and cause the card to be "locked" and cannot be unlocked, unless mechanically modified. We bought a bunch of chinese-copy adapters for cheap online, and all of these are working well. Problem was that "some" other slots may take these adapters properly, but some do NOT. Also the contact is erratic, so you may lose info, or stall the TF card, due to disconnect errors.
