Your computer has a wide range of built-in features and connection capabilities.
Using the media card reader
Your computer supports the following cards:
• Secure Digital (SD) card
• Secure Digital High Capacity (SDHC) card
• SD eXtended Capacity (SDXC) card
• MultiMediaCard (MMC)
Note: When transferring data to or from a flash media card, such as an SD card, do not put your computer in
sleep or hibernation mode before the data transfer is complete. To do so might cause damage to your data.
Inserting a flash media card
Attention: Before you start installing a flash media card, touch a metal table or a grounded metal object.
This action reduces any static electricity from your body. The static electricity could damage the card.
To insert a flash media card, do the following:
1. Make sure that the card is correctly oriented.
2. Insert the card firmly into the 4-in-1 media card reader slot. The card might stop before it is completely
installed into the slot.
Removing a flash media card
To remove a flash media card, do the following:
1. Push the flash media card until you hear a click.
2. Gently pull the flash media card out of the memory card slot.
Note: If you do not remove the card from your computer after you eject the card from the Windows
operating system, the card can no longer be accessed. To access the card, you must remove it once,
then insert it again.

depending on the power settings you use.
