Answer:
You need to refer to your user manual to see if your laptop has a card reader. Then you need to check it to see what types of cards it can take. Not all laptops have them in the same place, and not all laptops take the same types of cards (SD, SDHC, MMC, XD).
So because your question isn't specific enough, all I can say is check the manual...it's the reason the manufacturer made it and put it in the box with the laptop.
