Where is the SD slot in a Fujitsu Siemens Esprimo laptop?

The one that you described is the PC Card slot used, for example, a WiFi module. You didn't mention the model of the laptop. But for the Fujitsu-Siemens ESPRIMO Mobile D9500 Laptop, the memory card slot is located on the left-hand side of the laptop, just above the mic & headphone jack. You might want to add more details for others to know. I'll get back to you as soon as you update your question. Hope this helps. God bless!
