HP Probook 6450 B User Guide

							CAUTION:To reduce the risk of damage to the computer, damage to a drive, or loss of information,
observe these precautions:
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.
Before handling a drive, discharge static electricity by touching the unpainted metal surface of the drive.
Do not touch the connector pins on a removable drive or on the computer.
Handle a drive carefully; do not drop a drive or place items on it.
Before removing or inserting 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 through the
operating system.
Do not use excessive force when inserting a drive into a drive bay.
Do not type on the keyboard or move the computer while an optional optical drive is writing to a disc.
The write process is sensitive to vibration.
When the battery is the only source of power, be sure that the battery is sufficiently charged before
writing to media.
Avoid exposing a drive to temperature or humidity extremes.
Avoid exposing a drive to liquids. Do not spray the drive with cleaning products.
Remove media from a drive before removing the drive from the drive bay, or traveling with, shipping, or
storing a drive.
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. The airport security devices that check carry-on luggage, such as
conveyor belts, use X-rays instead of magnetism and will not damage a drive.
Handling drives 81 
						

							Improving hard drive performance
Using Disk Defragmenter
As you use the computer, files on the hard drive become fragmented. Disk Defragmenter consolidates
the fragmented files and folders on the hard drive so that the system can run more efficiently.
After you start Disk Defragmenter, it works without supervision. Depending on the size of your hard drive
and the number of fragmented files, Disk Defragmenter may take more than an hour to complete. You
may want to set it to run during the night or another time when you do not need access to your computer.
HP recommends defragmenting your hard drive at least once a month. You may set Disk Defragmenter
to run on a monthly schedule, but you can defragment your computer manually at any time.
NOTE:It is not necessary to run Disk Defragmenter on solid-state drives.
To run Disk Defragmenter:
1.Select Start > All Programs > Accessories > System Tools > Disk Defragmenter.
2.Click Defragment disk.
NOTE:Windows includes the User Account Control feature to improve the security of your
computer. You may be prompted for your permission or password for tasks such as installing
software, running utilities, or changing Windows settings. Refer to Help and Support for more
information.
For additional information, access the Disk Defragmenter software Help.
Using Disk Cleanup
Disk Cleanup searches the hard drive for unnecessary files that you can safely delete to free up disk
space and help the computer to run more efficiently.
To run Disk Cleanup:
1.Select Start > All Programs > Accessories > System Tools > Disk Cleanup.
2.Follow the on-screen instructions.

							Using HP 3D DriveGuard 
HP 3D DriveGuard protects the hard drive by parking the drive and halting I/O 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.
A short time after the end of one of these events, HP 3D DriveGuard returns the hard drive to normal
operation.
NOTE:Because solid-state drives (SSD) lack moving parts, HP 3D DriveGuard is unnecessary.
NOTE:If the upgrade bay contains a hard drive, the hard drive is protected by HP 3D DriveGuard.
Hard drives installed in optional docking devices or connected to USB ports are not protected by HP 3D
DriveGuard.
For more information, refer to the HP 3D DriveGuard software Help.
Identifying HP 3D DriveGuard status
The drive light on the computer changes to an amber color to show that the drive is parked. To determine
whether drives are currently protected or whether a drive is parked, select Start > Control Panel >
Hardware and Sound > Windows Mobility Center:
●If the software is enabled, a green check mark is superimposed over the hard drive icon.
●If the software is disabled, a red X is superimposed over the hard drive icon.
●If the drives are parked, a yellow moon is superimposed over the hard drive icon.
NOTE:The icon in the Mobility Center may not show the most up-to-date status for the drive. For
immediate updates after a change in status, you need to enable the notification area icon.
To enable the notification area icon:
1.Select Start > Control Panel > Hardware and Sound > HP 3D DriveGuard.
NOTE:If prompted by User Account Control, click Yes.
2.On the Icon in system tray row, click Show.
3.Click OK.
If HP 3D DriveGuard has parked the drive, the computer will behave in the following ways:
●The computer will not shut down.
●The computer will not initiate Sleep or Hibernation, except as described in the following Note.
NOTE:If the computer is running on battery power and reaches a critical battery level, HP 3D
DriveGuard allows the computer to initiate Hibernation.
Before you move the computer, HP recommends that you either shut it down or initiate Sleep or
Hibernation.
Using HP 3D DriveGuard 83 
						

							Using HP 3D DriveGuard software
The HP 3D DriveGuard software enables you to perform the following tasks:
●Enable and disable HP 3D DriveGuard.
NOTE:Permission to enable or disable HP 3D DriveGuard is dependent on certain user
privileges. Members of an Administrator group can change privileges for non-Administrator users.
●Determine whether a drive in the system is supported.
To open the software and change settings, follow these steps:
1.In Mobility Center, click the hard drive icon to open the HP 3D DriveGuard window.
– or –
Select Start > Control Panel > Hardware and Sound > HP 3D DriveGuard.
