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.
NOTE:It is not necessary to run Disk Defragmenter on solid-state drives.
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 at 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.
54 Chapter 8   Drives 
						

							To run Disk Defragmenter:
1.Connect the computer to AC power.
2.From the Start screen, type disk.
3.Click Optimize.
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 HP Support Assistant. To
access HP Support Assistant, from the Start screen, select the HP Support Assistant app.
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.From the Start screen, type disk, and then select Uninstall apps to free up disk space.
2.Follow the on-screen instructions.
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.
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 (SSDs) lack moving parts, HP 3D DriveGuard is unnecessary.
NOTE:A hard drive in a primary hard drive bay or in a secondary hard drive bay is protected by HP
3D DriveGuard. A hard drive installed in an optional docking devices or connected to a USB port is
not protected by HP 3D DriveGuard.
For more information, see the HP 3D DriveGuard software Help.
Identifying HP 3D DriveGuard status
The hard drive light on the computer changes color to show that a drive in the primary hard drive bay
and/or the drive in a secondary hard drive bay (select models only) is parked. To determine whether a
drive is currently protected or whether it is parked, view the icon on the Windows desktop in the
notification area, at the far right of the taskbar, or in the Mobility Center.

							9 Security
Protecting the computer
Standard security features provided by the Windows operating system and the non-Windows
Computer Setup utility (BIOS) can protect your personal settings and data from a variety of risks.
NOTE:Security solutions are designed to act as deterrents. These deterrents may not prevent a
product from being mishandled or stolen.
NOTE:Before you send your computer for service, back up and delete confidential files, and
remove all password settings.
NOTE:Some features listed in this chapter may not be available on your computer.
NOTE:Your computer supports Computrace, which is an online security-based tracking and
recovery service available in select regions. If the computer is stolen, Computrace can track the
computer if the unauthorized user accesses the Internet. You must purchase the software and
subscribe to the service in order to use Computrace. For information about ordering the Computrace
software, go to

*Computer Setup is a preinstalled, ROM-based utility that can be used even when the operating system is not working or will
not load. You can use either a pointing device (TouchPad, pointing stick, or USB mouse) or the keyboard to navigate and
make selections in Computer Setup.
Using passwords
A password is a group of characters that you choose to secure your computer information. Several
types of passwords can be set, depending on how you want to control access to your information.
56 Chapter 9   Security 
						

							Passwords can be set in Windows or in the non-Windows Computer Setup utility that is preinstalled
on the computer.
●BIOS administrator and DriveLock passwords are set in Computer Setup and are managed by
the system BIOS.
●Automatic DriveLock passwords are enabled in Computer Setup.
●Windows passwords are set only in the Windows operating system.
●If HP SpareKey has been set up previously, and if you forget the BIOS administrator password
set in Computer Setup, you can use HP SpareKey to access the utility.
●If you forget both the DriveLock user password and the DriveLock master password set in
Computer Setup, the hard drive that is protected by the passwords is permanently locked and
can no longer be used.
You can use the same password for a Computer Setup feature and for a Windows security feature.
You can also use the same password for more than one Computer Setup feature.
Use the following tips for creating and saving passwords:
●When creating passwords, follow requirements set by the program.
●Do not use the same password for multiple applications or websites, and do not reuse your
Windows password for any other application or website.
●Use HP Client Security's Password Manager to store your user names and passwords for all of
your websites and applications. You can securely read them in the future if they cannot be
remembered.
●Do not store passwords in a file on the computer.
The following tables list commonly used Windows and BIOS administrator passwords and describe
their functions.
Setting passwords in Windows

DriveLock user password* Protects access to the internal hard drive that is protected by
DriveLock, and is set under DriveLock Passwords during the

Managing a Computer Setup DriveLock password
CAUTION:To prevent the DriveLock-protected hard drive from becoming permanently unusable,
record the DriveLock user password and the DriveLock master password in a safe place away from
your computer. If you forget both DriveLock passwords, the hard drive will be permanently locked and
can no longer be used.
DriveLock protection prevents unauthorized access to the contents of a hard drive. DriveLock can be
applied only to the internal hard drive(s) of the computer. After DriveLock protection is applied to a
drive, a password must be entered to access the drive. The drive must be inserted into the computer
or an advanced port replicator in order for it to be accessed by the DriveLock passwords.
NOTE:A BIOS Administrator password must be set before you can access the DriveLock features.
To apply DriveLock protection to an internal hard drive, a user password and a master password
must be set in Computer Setup. Note the following considerations about using DriveLock protection:
Using passwords 59 
						

							●After DriveLock protection is applied to a hard drive, the hard drive can be accessed only by
entering either the user password or the master password.

owner of the master password may be either a system administrator or the day-to-day user.
●The user password and the master password can be identical.
●You can delete a user password or master password only by removing DriveLock protection
