How do you insert a SD card in the Dell latitude D820 laptop?

It is difficult to tell as we do not know what type of "DELL Laptop" you have. But there is a fool-proof way, unless the port isn't working, you can buy a memory-card reader and plug it in to the reletive spot. Then you insert the SD card in the dedicated spot for SD cards and off you go. You may have to install the hardware before it works. Pepper815762- I have a DELL LATITUDE D610. I can't buy a memory card reader, so what should I do?
