8 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 and by replacing a hard drive or adding memory. 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 by performing regular maintenance tasks, using tools such as
Disk Defragmenter and Disk Cleanup, you can drastically improve the performance of your computer.
Also, as your computer gets older, you might consider installing larger drives and adding more
memory.
Handling drives
Observe these precautions when handling drives:
● When the battery is the only source of power, be sure that the battery is sufficiently charged
before writing to media.
● Do not move an optical drive while it 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 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.
