7 Maintaining your computer
It is important to perform regular maintenance to keep your computer in optimal condition. This
chapter provides information about improving the performance of your computer by running tools
such as Disk Defragmenter and Disk Cleanup. It also provides information about updating your
programs and drivers, instructions for cleaning your computer, and tips for traveling with your
computer.
Improving performance
Everyone wants a fast computer and you can drastically improve the performance of your computer
by performing regular maintenance tasks with tools such as Disk Defragmenter and Disk Cleanup.
Also, as your computer gets older, you might consider installing larger drives and adding more
memory.
Handling drives
Observe these precautions when handling drives:
● Before removing or installing a drive, shut down the computer. If you are unsure whether the
computer is off, in the Sleep state, or in Hibernation, turn the computer on, and then shut it
down.
● Before handling a drive, discharge static electricity by touching a grounded surface.
● Do not touch the connector pins on a removable drive or on the computer.
● Do not use excessive force when inserting a drive into a drive bay.
● If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective
packaging and label the package “FRAGILE.”
● Avoid exposing a drive to magnetic fields. Security devices with magnetic fields include airport
walk-through devices and security wands. Airport conveyer belts and similar security devices
that check carry-on baggage use X-rays instead of magnetism and do not damage drives.
● Remove media from a drive before removing the drive from the drive bay, or traveling with,
shipping, or storing a drive.
● Do not type on the keyboard or move the computer while an optical drive is writing to a disc. The
write process is sensitive to vibration.
● Before you move a computer that is connected to an external hard drive, initiate Sleep and allow
the screen to clear, or properly disconnect the external hard drive.
Using HP 3D DriveGuard
HP 3D DriveGuard protects a hard drive by parking the drive and halting data requests under either of
the following conditions:
● You drop the computer.
● You move the computer with the display closed while the computer is running on battery power.
