Hybrid Graphics and AMD Dual Graphics (select models only)
Select computers are equipped with either the Hybrid Graphics feature or the AMD Dual Graphics
feature.
NOTE:To determine whether Hybrid Graphics or AMD Dual Graphics is installed on your computer,
see your notebook graphics processor configuration and software Help.
Both Hybrid Graphics and AMD Dual Graphics offer two modes for processing graphics:
●High Performance mode—Applications assigned to this mode run on the higher-performance
graphics processing unit (GPU) for optimal performance.
●Power Saving mode—Applications assigned to this mode run on the lower-performance GPU to
conserve battery power.
Using Hybrid Graphics (select models only)
The Hybrid Graphics feature allows an application to run in either High Performance mode or Power
Saving mode, based on the application’s graphics-processing demands. Typically, 3D and gaming
applications run on the higher-performance GPU, and applications with lightweight graphics-
processing demands run on the lower-performance GPU. You can change the mode an application
uses (High Performance or Power Saving) through the Hybrid Graphics control panel.
NOTE:Due to hardware limitations, some applications can be run in only one of the two modes.
For more information, see your Hybrid Graphics software Help.
Hybrid Graphics and AMD Dual Graphics (select models only) 41 
						

							Using AMD Dual Graphics (select models only)
The AMD Dual Graphics feature allows the AMD accelerated processing unit (APU) and the discrete
AMD graphics card to work together. When AMD Dual Graphics is enabled, graphics performance
improves over the performance available using only one of the graphics devices. This improvement
applies to DirectX versions 10 or 11 (DX10 and DX11) applications operating in full-screen mode. In
windowed mode or when running non-DX10/11 applications, the system operates in a manner similar
to Hybrid Graphics.

							7 Maintaining your computer
It is important to perform regular maintenance to keep your computer in optimal condition by using
tools like Disk Defragmenter and Disk Cleanup. This chapter also includes ways to update programs
and drivers, steps to clean the computer, and tips for traveling with (or shipping) the computer.
Improving performance
You can improve the performance of your computer by performing regular maintenance tasks with
tools such as Disk Defragmenter and Disk Cleanup.
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
through the operating system.
●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.
●Do not use excessive force when inserting a drive into a drive bay.
●When the battery is the only source of power, be sure that the battery is sufficiently charged
before writing to media.
●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 (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.
Improving performance 43 
						

							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.
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:
1.Connect the computer to AC power.
2.Select Start > All Programs > Accessories > System Tools > Disk Defragmenter.
3.Follow the on-screen instructions.
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 run more efficiently.
To run Disk Cleanup:
1.Select Start > All Programs > Accessories > System Tools > Disk Cleanup.
2.Follow the on-screen instructions.
Updating programs and drivers
HP recommends that you update your programs and drivers on a regular basis to the latest versions.
Updates can resolve issues and bring new features and options to your computer. Technology is
44 Chapter 7   Maintaining your computer 
						

							always changing, and updating programs and drivers allows your computer to run the latest
technology available. For example, older graphics components might not work well with the most
recent gaming software. Without the latest driver, you would not be getting the most out of your
equipment.
