Table D-4 Solving Media Card Reader Problems (continued)
Do not know how to remove a media card correctly.
Cause
The computer's software is used to safely eject the card.
After installing the media card reader and booting to Windows, the reader and the inserted cards are not recognized
by the computer.
Cause
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.
After inserting a media card in the reader, the computer attempts to boot from the media card.
Cause
The inserted media card has boot capability.
Computer will not boot from a USB removable drive or media that is inserted in the USB port on the media card reader.
Cause
The media card reader is connected to the computer via the
PCI card, which is not supported on the HP Desktop BIOS.
After installing the media card reader, the front USB ports on the computer do not work.
Cause
The USB cable for the front USB ports was disconnected so
that the system board connector could be used for the reader.
150 Appendix D Troubleshooting Without Diagnostics
Solution
Open My Computer, right-click on the corresponding drive
icon, and select Eject. Then pull the card out of the slot.
NOTE: Never remove the card when the green LED is
flashing
Solution
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.
Solution
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.
Solution
The bootable USB device will have boot support if you connect
the media card reader to an available USB connector on the
computer's system board. If no connector is available, plug the
bootable device into a different USB port on the computer.
Solution
Reconnect the cable for the front USB ports. Install the PCI
card and connect the media reader to the USB connector on
the PCI card.
