Right click on my computer,click on properties,Click on Hardware Tab,Click on Device Manager tab.Here u can find ur multimedia reader.If it is disabled it shows red cross on it.Or if it is not installed it shows yellow exclamatory sign on it.

Have you tried dell's website for any drivers. If there are, reinstall them and see if that fixes it.

Have a look into the device manager, right click my computer, select manage, then on the left side of the management window click on device manager, plug in the sd, do you see any ? or ! or yellow marks or unknown devices that a driver would be missing from or malfunctioning?

I would like to inform you that Acer's laptop doesn't support all kinds SD memory cards available in local market. Its not compatible with all physical dimensions of various memory card companies. So in that case you need to use EXTERNAL Memory card reader which is attachable to USB ports.

If this solution was helpful to you then please rate 100% (or FIXYA) for this solution, otherwise don't rate at all. It was my pleasure helping you.
