Some models might also have a smart-card-reader slot. Smart cards can be used for authentication,
data storage, and application processing. Smart cards also might provide strong security authentication
for single sign-on (SSO) within large organizations.
Attention:
• While transferring data to or from a flash media card, or a smart card, do not put your computer into sleep
or hibernation mode before the data transfer is completed; otherwise, your data could become damaged.
• Depending on the model, the computer might also have an integrated smart-card reader. Ensure that
you insert a correct type of smart card (as shown in figure A) into the smart-card reader. Do not insert
a non-support card or a card with slits (as shown in figure B and figure C) into the smart-card reader.
Otherwise, the smart card reader might get damaged.
Installing a flash media card or a smart card
To install a card, do the following:
Attention: Before you start installing a 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.
1. Locate the appropriate type of slot for your card. See "Locating computer controls, connectors, and
indicators" on page 1.
2. Make sure that the card is correctly oriented:
• For flash media card: The metal contacts are facing down and pointing toward the card slot.
• For smart card: The metal contacts are facing upward and pointing toward the card slot.
3. Press the card firmly into the card slot.
If the plug-and-play feature is not enabled for the installed flash media card or smart card, do the following
to enable the feature:
1. Open Control Panel.
2. Click Hardware and Sound.
3. Click Device Manager. If you are prompted for an administrator password or confirmation, type the
password or provide confirmation.
4. From the Action menu, select Add legacy hardware. The Add Hardware Wizard starts.
5. Follow the instructions on the screen.
Removing a flash media card or a smart card
