HP D3K72UT D3K72UT#ABA manual Table D-6Solving Display Problems

After installing the media card reader and booting to Windows, the reader and the inserted cards are not recognized by the computer.

Cause Solution

The operating system needs time to recognize the device if the reader was just installed into the computer and you are turning the PC on for the first time.

Wait a few seconds so that the operating system can recognize the reader and the available ports, and then recognize whatever media is inserted in the reader.

After inserting a media card in the reader, the computer attempts to boot from the media card.

Cause Solution

The inserted media card has boot capability.

If you do not want to boot from the media card, remove it during boot or do not select the option to boot from the inserted media card during the boot process.
