Using an SD Card or MMC
CAUTION: To prevent damage to the SD Card connectors:
Use minimal force when inserting an SD Card or MMC into an SD
Card slot.
Do not move or transport the notebook while an SD Card or MMC
is inserted.
SD (Secure Digital) Cards and MMCs (multimedia cards) are
flash memory cards that provide secure data storage and
convenient data sharing. These cards are often used with SD-
equipped cameras and PDAs as well as notebooks. The SD Card
features on the notebook support both SD Cards and MMCs.
Using the SD Card Light
The SD Card light turns on when an inserted SD Card or MMC
is being accessed. The SD Card light turns off when an inserted
SD Card or MMC is inactive or when the SD Card slot is empty.
