CD and DVD drive problems
NOTE: High-speed CD or DVD drive vibration is normal and may cause noise, which does not indicate a defect in
the drive or the CD or DVD.
NOTE: Because of different regions worldwide and different disc formats, not all DVD titles work in all DVD drives.
Problems writing to a CD/DVD-RW drive
CLOSE OTHER PROGRAMS —The CD/DVD-RW drive must receive a steady stream of data when writing. If the
stream is interrupted, an error occurs. Try closing all programs before you write to the CD/DVD-RW.
TURN OFF STANDBY MODE IN WINDOWS BEFORE WRITING TO A CD/DVD-RW DISC —See "Standby Mode" on
page31 or search for the keyword standby in the Windows Help and Support Center for information on power
management modes.
CHANGE THE WRITE SPEED TO A SLOWER RATE —See the help files for your CD or DVD creation software.
If you cannot eject the CD, CD-RW, DVD, or DVD+RW drive tray
1
Ensure that the computer is turned off.
2
Straighten a paper clip and insert one end into the eject hole at the front of the drive; push firmly until
the tray is partially ejected.
3
Gently pull out the tray until it stops.
If you hear an unfamiliar scraping or grinding sound
• Ensure that the sound is not caused by the program that is running.
• Ensure that the disk or disc is inserted properly.
Hard drive problems
ALLOW THE COMPUTER TO COOL BEFORE TURNING IT ON —A hot hard drive may prevent the operating system
from starting. Try allowing the computer to return to room temperature before turning it on.
