Micro sdcard not detected in my laptop but in smartphone it is.
Have you updated all the drivers for USB on your laptop? If you did, then I would recommend that you change the adapter for SD cards that you connect the card in. How do you connect the SD card with the other laptops? Are you using the same adapter or not? If not, then the suspected failure is within the adapter.
Make sure that the SD card has a recognizable by the laptop format.
