							Securing Your Computer91
If you do not enter the correct password in three attempts, the computer tries to 
start from another bootable device if the 
Boot First Device option in system 
setup is set to allow start-up from another device. If the 
Boot First Device 
option is not set to allow the computer to start from another device, the 
computer returns to the operating state it was in when you turned it on.
If the hard drive password, the external hard-drive password, and the primary 
password are the same, the computer prompts you only for the primary 
password. If the hard drive password is different from the primary password, the 
computer prompts you for both. Two different passwords provide greater 
security.
 NOTE: The administrator password provides access to the computer, but it does 
not provide access to the hard drive when a hard drive password is assigned. 
Trusted Platform Module (TPM)
 NOTE: Computers shipping into China are not equipped with the TPM feature. 
 
NOTE: The TPM feature may not be supported in all countries. 
 
NOTE: The TPM feature supports encryption only if the operating system supports 
TPM. For more information, see the TPM software documentation and the help files 
that came with the software.
TPM is a hardware-based security feature that can be used to create and manage 
computer-generated encryption keys. When combined with security software, 
the TPM enhances existing network and computer security by enabling features 
such as file protection capabilities and protected e-mail. The TPM feature is 
enabled through a system setup option.
 NOTICE: To secure your TPM data and encryption keys, follow the backup 
procedures documented in the Broadcom Secure Foundation Getting Started 
Guide. In the event of these backups being incomplete, lost, or damaged, Dell will 
be unable to assist in the recovery of encrypted data.

Computer Tracking Software
Computer tracking software may enable you to locate your computer if it is lost 
or stolen. The software is optional and may be purchased when you order your 
Dell™ computer, or you can contact your Dell sales representative for 
information about this security feature.
 NOTE: Computer tracking software may not be available in certain countries.
 
NOTE: If you have computer tracking software and your computer is lost or stolen, 
you must contact the company that provides the tracking service to report the 
missing computer.
If Your Computer Is Lost or Stolen
• Call a law enforcement agency to report the lost or stolen computer. 
Include the Service Tag in your description of the computer. Ask that a 
case number be assigned and write down the number, along with the 
name, address, and phone number of the law enforcement agency. If 
possible, obtain the name of the investigating officer.
 NOTE: If you know where the computer was lost or stolen, call a law enforcement 
agency in that area. If you do not know, call a law enforcement agency where you 
live.
• If the computer belongs to a company, notify the security office of the 
company. 
						

							94Securing Your Computer
• Contact Dell customer service to report the missing computer. Provide the 
computer Service Tag, the case number, and the name, address, and phone 
number of the law enforcement agency to which you reported the missing 
computer. If possible, give the name of the investigating officer.
The Dell customer service representative will log your report under the 
computer Service Tag and record the computer as missing or stolen. If someone 
calls Dell for technical assistance and gives your Service Tag, the computer is 
identified automatically as missing or stolen. The representative will attempt to 
get the phone number and address of the caller. Dell will then contact the law 
enforcement agency to which you reported of the missing computer.

safety instructions that shipped with your computer.
Your computer has three keyboard status lights located above the keyboard. 
During normal operation, the keyboard status lights display the current status 
(
on or off) of the Num Lock, Caps Lock, and Scroll Lock features. If the 
computer starts without error, the lights flash, and then turn off. If the 
computer malfunctions, however, you can use the status of the lights to help 
identify the problem.
 NOTE: After the computer completes POST, the Num Lock light may remain on, 
depending on your BIOS settings. For more information on using the system setup 
program, see System Setup Program on page 135.
Diagnostic Light Codes During POST
To troubleshoot a problem with your computer, read the sequence of the 
keyboard status lights in order from left to right (Num Lock, Caps Lock, and 
then Scroll Lock). If the computer malfunctions the individual lights display a 
status of either 
On , Off , or Flashing .
