							6 Managing power
Your computer can operate on either battery power or external power. When the computer is running
on battery power only and an AC power source is not available to charge the battery, it is important to
monitor and conserve the battery charge. Your computer supports an optimal power plan to manage
how your computer uses and conserves power so that computer performance is balanced with power
conservation.
Initiating Sleep and Hibernation
Microsoft® Windows has two power-saving states, Sleep and Hibernation.
●Sleep—The Sleep state is automatically initiated after a period of inactivity when running on
battery power or on external power. Your work is saved to memory, allowing you to resume your
work very quickly. You can also initiate Sleep manually. For more information, see 
Manually
initiating and exiting Sleep on page 34.
●Hibernation—The Hibernation state is automatically initiated if the battery reaches a critical level.
In the Hibernation state, your work is saved to a hibernation file and the computer powers down.
NOTE:You can manually initiate Hibernation. See Manually initiating and exiting Sleep
on page 34 and Manually initiating and exiting Hibernation (select models only) on page 34.

							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.
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.
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.
40 Chapter 7   Maintaining your computer 
						

							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.From the Start screen, type disk.
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.From the Start screen, type disk, and then select Uninstall apps to free up disk space.
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
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.
