Drive Handling; Electrostatic Discharge Information - HP ENVY x360 Maintenance And Service Manual

Drive handling

Note the following guidelines when handling drives.
IMPORTANT:
damage to the computer, damage to a drive, or loss of information, observe these
precautions:
Before removing or inserting a hard drive, shut down the computer. If you are
●
unsure whether the computer is off or in Hibernation, turn the computer on, and
then shut it down through the operating system.
Before handling a drive, be sure that you are discharged of static electricity. While
●
handling a drive, avoid touching the connector.
Before removing an optical drive, be sure that a disc is not in the drive, and be sure
●
that the optical drive tray is closed.
Handle drives on surfaces covered with at least 2.54 cm (1 inch) of shock-proof
●
foam.
Avoid dropping drives from any height onto any surface.
●
After removing a hard drive or an optical drive, place it in a static-proof bag.
●
Avoid exposing an internal hard drive to products that have magnetic fields, such as
●
monitors or speakers.
Avoid exposing a drive to temperature extremes or liquids.
●
If a drive must be mailed, place the drive in a bubble pack mailer or other suitable
●
form of protective packaging, and label the package "FRAGILE."

Electrostatic discharge information

A sudden discharge of static electricity from your finger or other conductor can destroy
static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but
damage occurs. An electronic device exposed to electrostatic discharge (ESD) might not
appear to be affected at all and can work perfectly throughout a normal cycle. The device
might function normally for a while, but it has been degraded in the internal layers,
reducing its life expectancy.
