Optical drive precautions
Be sure to observe the following guidelines while operating or cleaning the optical drive.
Operation
Do not move the drive during operation. This may cause it to malfunction during reading.
Avoid exposing the drive to sudden changes in temperature, as condensation may form inside the unit.
If the temperature suddenly changes while the drive is on, wait at least one hour before you turn off the
power. If you operate the unit immediately, it may malfunction while reading.
Avoid placing the drive in a location that is subject to high humidity, extreme temperatures, mechanical
vibration, or direct sunlight.
Cleaning
Clean the panel and controls with a soft, dry cloth or a soft cloth lightly moistened with a mild detergent
solution. Never spray cleaning fluids directly on the unit.
Avoid using any type of solvent, such as alcohol or benzene, which may damage the finish.
Safety
If any object or liquid falls into the drive, immediately unplug the computer and have it checked by an
authorized HP service provider.
Shipping preparation
Follow these suggestions when preparing to ship the computer:
1. Back up the hard drive files to an external storage device. Be sure that the backup media is not exposed
to electrical or magnetic impulses while stored or in transit.
NOTE: The hard drive locks automatically when the system power is turned off.
2. Remove and store all removable media.
3. Turn off the computer and external devices.
4. Disconnect the power cord from the electrical outlet, then from the computer.
5. Disconnect the system components and external devices from their power sources, then from the
computer.
NOTE: Ensure that all boards are seated properly and secured in the board slots before shipping the
computer.
6. Pack the system components and external devices in their original packing boxes or similar packaging
with sufficient packing material to protect them.
