3.Remove the hard drive bracket (3) from the hard drive. To install a hard drive, reverse this procedure. 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 52 Chapter 8 Maintaining your computer
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: ● If the software is actively protecting the drive, a green check mark is superimposed over the icon. ● If the software has been disabled, a no symbol is superimposed over the icon. ● If the software has parked the drive due to a shock event, an orange cone is superimposed over the icon. 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.From the Start screen, type d, and then type disk in the search box. Select Settings, and then select Defragment and optimize your drives. 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 d, and then type disk in the search box. Select Settings, and then select Free up disk space by deleting unnecessary files. 2.Follow the on-screen instructions. Adding or replacing memory modules Adding memory can help improve your computers performance. Your computer is like your physical work area.
