Solving Media Card Reader Problems
Table 2-5 Solving Media Card Reader Problems
Media card will not work in a digital camera after formatting it in Microsoft Windows XP.
Cause
Solution
By default, Windows XP will format any media card with a
capacity greater than 32MB with the FAT32 format. Most digital
cameras use the FAT (FAT16 & FAT12) format and can not
operate with a FAT32 formatted card.
Either format the media card in the digital camera or select FAT
file system to format the media card in a computer with
Windows XP.
A write-protected or locked error occurs when attempting to write to the media card.
Cause
Solution
Media card is locked. Locking the media card is a safety feature
that prevents writing to and deleting from an SD/Memory Stick/
PRO card.
If using an SD card, make sure that the lock tab located on the
right of the SD card is not in the locked position. If using a
Memory Stick/PRO card, make sure that the lock tab located
on the bottom of the Memory Stick/PRO card is not in the
locked position.
Can not write to the media card.
Cause
Solution
The media card is a read-only memory (ROM) card.
Check the manufacturer’s documentation included with your
card to see if it is writable.
Unable to access data on the media card after inserting it into a slot.
Cause
Solution
The media card is not inserted properly, is inserted in the wrong
slot, or is not supported.
Ensure that the card is inserted properly with the gold contact
on the correct side. The green LED will light if inserted properly.
Do not know how to remove a media card correctly.
Cause
Solution
The computer’s software is used to safely eject the card.
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.

Chapter 2 Troubleshooting Without Diagnostics
ENWW
Table 2-5 Solving Media Card Reader Problems (continued)
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.
Computer will not boot from a USB removable drive or media that is inserted in the USB port on the media card reader.
Cause
Solution
The media card reader is connected to the computer via the
PCI card, which is not supported on the HP Desktop BIOS.
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.
After installing the media card reader, the front USB ports on the computer do not work.
ENWW
Cause
Solution
The USB cable for the front USB ports was disconnected so
that the system board connector could be used for the reader.
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.

Solving Hardware Installation Problems
You may need to reconfigure the computer when you add or remove hardware, such as an additional
drive or expansion card. If you install a plug and play device, Windows XP automatically recognizes the
device and configures the computer. If you install a non–plug and play device, you must reconfigure the
computer after completing installation of the new hardware. In Windows XP, use the Add Hardware
Wizard and follow the instructions that appear on the screen.
WARNING! When the computer is plugged into an AC power source, voltage is always applied
to the system board. To reduce the risk of personal injury from electrical shock and/or hot
surfaces, be sure to disconnect the power cord from the wall outlet and allow the internal system
components to cool before touching.
Look for the LED on the system board. If the LED is illuminated, the system still has power. Power
off the computer and remove the power cord before proceeding.

POST Error Messages
This appendix lists the error codes, error messages, and the various indicator light and audible
sequences that you may encounter during Power-On Self-Test (POST) or computer restart, the probable
source of the problem, and steps you can take to resolve the error condition.
POST Message Disabled suppresses most system messages during POST, such as memory count
and non-error text messages. If a POST error occurs, the screen will display the error message. To
manually switch to the POST Messages Enabled mode during POST, press any key (except F10 or
F12). The default mode is POST Message Disabled.
The speed at which the computer loads the operating system and the extent to which it is tested are
determined by the POST mode selection.
Quick Boot is a fast startup process that does not run all of the system level tests, such as the memory
test. Full Boot runs all of the ROM-based system tests and takes longer to complete.
Full Boot may also be enabled to run every 1 to 30 days on a regularly scheduled basis. To establish

Password Security and Resetting
CMOS
This computer supports security password features, which can be established through the Computer
Setup Utilities menu.
This computer supports two security password features that are established through the Computer
Setup Utilities menu: setup password and power-on password. When you establish only a setup
password, any user can access all the information on the computer except Computer Setup. When you
establish only a power-on password, the power-on password is required to access Computer Setup and
any other information on the computer. When you establish both passwords, only the setup password
will give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on password
as an override to log in to the computer. This is a useful feature for a network administrator.
If you forget the password for the computer, there are two methods for clearing that password so you
can gain access to the information on the computer:
●
Resetting the password jumper
●
Restoring factory settings as defaults in Computer Setup
CAUTION Sliding the CMOS switch will reset CMOS values to factory defaults. It is important
to back up the computer CMOS settings before resetting them in case they are needed later.
Back up is easily done through Computer Setup. See the Computer Setup (F10) Utility Guide on
the Documentation and Diagnostics CD for information on backing up the CMOS settings.
ENWW
59
Resetting the Password Jumper
To disable the power-on or setup password features, or to clear the power-on or setup passwords,

1.
Shut down the operating system properly, then turn off the computer and any external devices,
and disconnect the power cord from the power outlet.
2.
With the power cord disconnected, press the power button again to drain the system of any residual
power.
WARNING! To reduce the risk of personal injury from electrical shock and/or hot surfaces,
be sure to disconnect the power cord from the wall outlet, and allow the internal system
components to cool before touching.
CAUTION When the computer is plugged in, the power supply always has voltage applied
to the system board even when the unit is turned off. Failure to disconnect the power cord
can result in damage to the system.
Static electricity can damage the electronic components of the computer or optional
equipment. Before beginning these procedures, ensure that you are discharged of static
electricity by briefly touching a grounded metal object. See the Hardware Reference
Guide on the Documentation and Diagnostics CD for more information.

support.
60
5.
Remove the jumper from pins 1 and 2. Place the jumper on either pin 1 or 2, but not both, so that
it does not get lost.
6.
Replace the computer cover or access panel.
7.
Reconnect the external equipment.
8.
Plug in the computer and turn on power. Allow the operating system to start. This clears the current
passwords and disables the password features.

Drive Protection System (DPS)
The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in some
computers. DPS is designed to help diagnose problems that might result in unwarranted hard drive
replacement.
When these systems are built, each installed hard drive is tested using DPS, and a permanent record
of key information is written onto the drive. Each time DPS is run, test results are written to the hard
drive. Your service provider can use this information to help diagnose conditions that caused you to run
the DPS software.
Running DPS will not affect any programs or data stored on the hard drive. The test resides in the hard
drive firmware and can be executed even if the computer will not boot to an operating system. The time
required to execute the test depends on the manufacturer and size of the hard drive; in most cases, the
test will take approximately two minutes per gigabyte.
Use DPS when you suspect a hard drive problem. If the computer reports a SMART Hard Drive Detect
Imminent Failure message, there is no need to run DPS; instead, back up the information on the hard
drive and contact a service provider for a replacement hard drive.
ENWW
63
Accessing DPS Through Computer Setup
When the computer does not power on properly you should use Computer Setup to access the DPS
program. To access DPS, perform the following steps:
1.
Turn on or restart the computer.
2.
When the F10 Setup message appears in the lower-right corner of the screen, press the F10 key.
NOTE If you do not press the F10 key while the message is displayed, you must turn the
computer off, then on again, to access the utility.
A choice of five headings appears in the Computer Setup Utilities menu: File, Storage,
Security, Power, and Advanced.
3.
Select Storage > DPS Self-Test.
The screen will display the list of DPS-capable hard drives that are installed on the computer.
NOTE If no DPS-capable hard drives are installed, the DPS Self-Test option will not
appear on the screen.
4.
Select the hard drive to be tested and follow the screen prompts to complete the testing process.
When the test has been completed, one of three messages will be displayed:
●
Test Succeeded. Completion Code 0.
●
Test Aborted. Completion Code 1 or 2.
●
Test Failed. Drive Replacement Recommended. Completion Code 3 through 14.
If the test failed, the completion code should be recorded and reported to your service provider for help
in diagnosing the computer problem.
