							Sensorbased on the amount  of light  in the surroundings.
LCD
BrightnessThis option (represented by a  slider bar for On  Battery  and  On  AC)  sets  the panel brightness when  the
ambient  light  sensor is off.
Security
Option Description
Admin
Password This field lets you set, change, or delete the administrator password.  The  administrator password enables
several  security features when  set  including:
Restricts  changes to  the settings in Setup.
Restricts  the boot devices listed  in the  Boot Menu to  those  enabled  in the 
Boot  Sequence
field.
Prohibits  changes to  the owner and  asset tags.
Substitutes for the system  password if the system  prompts  for a  password during power on.
Successful  changes to  this password take  effect immediately.
If  you delete the admin  password,  the system  password is also  deleted. Also, the admin  password can  be
used to  delete the   hard drive  password.  For  this reason, you cannot set  an admin  password if a  system
password or hard drive  is already set. The  admin  password must  be set  first if used in conjunction with a
system  and/or  hard drive  password.
System
Password This field lets you set, change, or delete the system  password.
Internal  
hard drive
PW This field lets you set, change, or delete the password on the systems internal hard drive. Successful
changes take  place  immediately  and  require a  system  restart. The
  hard drive  password travels with the
hard drive, so the hard drive  is protected  even when  installed  in another system.
Password
Bypass This option lets you bypass the system  and  internal hard drive  password prompts  during a  system  restart  or
when  resuming  from  a  standby state. Settings are 
Disabled, Reboot Bypass , Resume Bypass ,  and
Reboot &  Resume Bypass .
The  system  will always prompt for the set  system  and  internal hard drive  password when  powered on from
an off state  (cold boot).
Default setting:  Disabled
Password
Change This option lets you determine  whether  changes to  the System  and  hard drive  passwords  are permitted
when  an Admin  password is set. Use  the check  box to  allow or disallow changes.
Default setting: 
Allow Non-Admin  Password  Changes
TPM  Security This option lets you control whether  the Trusted Platform Module (TPM) in the system  is enabled  and  visible
to  the operating  system. When  disabled (check box is empty), the BIOS will not turn  on the TPM during
POST. The  TPM will be non-functional  and  invisible to  the operating  system. When  enabled  (check box
filled)  the BIOS will turn  the TPM on during POST  so the it  can  be used by the operating  system.
Disabling  this option does  not change  any settings you may have  made to  the TPM,  nor does  it  delete or
change  any information  or keys you may have  stored  there.  It simply  turns  off the TPM so that  it  cannot be
used. When  you re -enable the TPM,  it  will function exactly as it  did  before it  was  disabled.
Once TPM is enabled  (check box filled), the available  settings are 
Deactivate, Activate ,  and  Clear.
With the TPM in Deactivate  mode, it  will not execute  any commands that  use the resources  of the TPM,  nor
will it  allow any access  to  stored  owner information.
The  Clear  setting  allows  the owners information  stored  in the TPM to  be cleared.  Use  this to  restore the
TPM to  its  default state  if you lose or forget the owner authentication  data.
Computrace® This field lets you activate or disable  the BIOS module interface of the optional  Computrace software.  The
settings are 
Deactivate, Disable ,  and  Activate .
The  Activate and  Disable options will permanently  activate or disable  the feature  and  no further changes will
be allowed.
CPU  XD
Support This field enables  or disables the Execute Disable mode of the processor. Use  the check  box to  enable /
disable  this feature.
Default setting:

							Non-Admin
Setup
ChangesThis option lets you determine  whether  changes to  the setup  option are permitted when  an administrator
password is set. If  disabled the setup  option is locked by the admin  password.  It cannot be modified unless
setup  is unlocked.  Use  the check  boxes  to  allow / deny  access  to  the Wi -Fi  Catcher Changes and  / or
Wireless  Switch Changes within  the system  setup.

are running  in DOS).
Default setting: 
Enabled
