Everyone inadvertently deletes files at one time or another. Also, hard-disk drives can
fail after extended use, so it is not a question of
whether you will eventually lose data,
but
when. To avoid such loss of data, you should regularly make backup copies of all
hard-disk drive files.

Dell recommends that you back up the hard-disk drive at least once a week and per-
form a daily backup of those files known to have been changed, such as your data
files. Doing so ensures that you lose no more than a week’s work and most likely only
a day’s work.
Because your Dell OptiPlex NX1 system is connected to a network, most of the
backup process is automatic. Your network administrator should have a backup loca-
tion created on a server and a process for you to follow when performing the backup.
If you have questions about the backup process, contact your network administrator.

Dell recommends keeping your work environment clean to reduce the amount of dust
and dirt around the computer, thereby reducing the amount of contaminants drawn
into the computer by the power supply fan. Contaminant buildup increases the com-
puter’s internal temperature and interferes with the operation of various system
components.
In particular, you should keep the exterior of your computer and monitor clean.
A conventional monitor or keyboard cover minimizes the accumulation of dust and
other debris inside the monitor and keyboard when they are not in use. Also, commer-
cially available keyboard membrane covers make it possible to use the keyboard while
providing protection against foreign particles.
