Manageability
Alert Standard Format
ASF is a DMTF management standard that specifies "pre-operating system" or "operating system-absent" alerting techniques. It is designed to generate an
alert on potential security and fault conditions when the operating system is in a sleep state or the computer is powered down. ASF is designed to supersede
previous operating system-absent alerting technologies.
Your computer supports the following ASF alerts and remote capabilities:
For more information about Dell's ASF implementation, see the ASF User's Guide and the ASF Administrator's Guide, available on the Dell Support website at
support.dell.com.

Padlock Ring and Security Cable Slot
Use one of the following methods to secure your computer:
lUse a padlock alone or a padlock and looped security cable with the padlock ring. For location of the padlock ring, see "Inside Your Computer."
A padlock alone prevents the computer from being opened.
A security cable looped around a stationary object is used in conjunction with a padlock to prevent unauthorized movement of the computer.
lAttach a commercially available antitheft device to the security cable slot on the back of the computer.
Antitheft devices usually include a segment of metal-stranded cable with an attached locking device and key. A Kensington lock is recommended. The
documentation that comes with the locking device contains instructions for installing it.
Password Protection
System Password
Option Settings
You cannot change or enter a new system password if either of the following two options is displayed:
lEnabled —A system password is assigned.

NOTE: Before you purchase an antitheft device, ensure that it works with the security cable slot on your computer.
NOTICE: Although passwords provide security for the data on your computer, they are not foolproof. If your data requires more security, it is your
responsibility to obtain and use additional forms of protection, such as data encryption programs.
NOTICE: If you leave your computer running and unattended without having a system password assigned, or if you leave your computer unlocked so
that someone can disable the password by changing a jumper setting, anyone can access the data stored on your hard drive.
