Improving hard drive performance
Using Disk Defragmenter
As you use your computer over time, the files on the hard drive become fragmented. A fragmented drive 
means data on your drive is not contiguous (sequential) and, because of this, the hard drive works harder to 
locate files, thus slowing down the computer. Disk Defragmenter consolidates (or physically reorganizes) 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. However, depending on the size of your hard 
drive and the number of fragmented files, Disk Defragmenter may take more than an hour to complete.
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.
To run Disk Defragmenter:
Using hard drives61  
						

							1.Connect the computer to AC power.
2.Select Start > All Programs > Accessories > System Tools > Disk Defragmenter.
3.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. To access Help and Support, select 
Start > Help and Support.
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.Click Start > All Programs > Accessories > System Tools > Disk Cleanup.
2.Follow the on-screen instructions.
Using HP 3D DriveGuard (select models only)
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, they do not require HP 3D DriveGuard 
protection.NOTE:A hard drive in a primary hard drive bay or a secondary hard drive bay is protected by HP 3D 
DriveGuard. A hard drive installed in an optional docking device 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 the drive in a 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.

							9Security
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 
http://hp-pt.absolute.com.

							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. 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.

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:
66Chapter 9   Security   
						

							●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.
●The owner of the user password should be the day-to-day user of the protected hard drive. The 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 from the  drive. DriveLock protection can be removed from the drive only with the master password.
