CD and DVD Problems

If you can’t boot from a CD in the DVD/CD-RW drive

•Make sure the CD is bootable, such as the Recovery CDs.

•Make sure the DVD/CD-RW drive is selected as the boot device—see “Changing the Boot Device” on page 11.

•Restart the notebook.

•Test the DVD/CD-RW drive with the e-DiagTools diagnostics—see “Using the e-DiagTools Diagnostic Tests” on page 29.

If a CD or DVD plays erratically

•Dirt or smudges can cause a disk to skip. Clean the disk with a soft cloth. If the disk is badly scratched, it will probably have to be replaced.

•Some DVDs include software called “PC Friendly.” You generally should not install this software, as it can cause errors or erratic play. If needed, uninstall it and restart your notebook.

If a DVD movie stops playing in the middle

•You may have accidentally paused the DVD movie. Press the Play button to continue.

•The DVD may be double-sided. Open the DVD tray and read the text near the center hole of the disk. If it says Side A, flip the disk over, close the tray, and press the Play button to continue playing the movie.

If you get a Region Code error when playing a DVD movie

•DVDs can have regional codes embedded in the disk data. These codes prevent DVD movies from being played outside the region of the world in which they are sold. If you get a Region Code error, you are trying to play a DVD intended for a different region.

Important: most DVD drives let you change the region code only a limited number of times (usually no more than four). When you reach this limit, your last change to the region code will be hard-coded on the DVD drive, and will be permanent. Your HP warranty does not cover the expense of correcting this situation.

Refer to the help for your DVD player software for details about setting region codes.

If the notebook cannot read a CD or DVD

•Make sure the disk is properly inserted, and snapped down onto the spindle in the center of the tray.

•For a single-sided CD or DVD, make sure the disk is placed in the drive with the label facing up.

•Clean the disk with a soft cloth.

•Wait 5 to 10 seconds after closing the tray for the notebook to recognize the disk.

•Remove the disk from the drive, then restart the notebook.

•If you created the CD on a CD-RW drive module, try using a different media brand. For best results use HP certified media. While other media may work, HP cannot guarantee compatibility.
