Video
Option Description
LCD Brightness

This 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 (admin) password (sometimes called the "setup" password). The admin password enables several security features when set including:

  • Restricts changes to the settings in Setup
  • Restricts the boot devices listed in the <F12> 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 HDD password. For this reason, you cannot set an admin password if a system password or HDD is already set. The admin password must be set first if used in conjunction with a system and/or HDD password.
System Password

This field lets you set, change, or delete the system password (previously called the "Primary" password).

Internal HDD PW

This field lets you set, change, or delete the password on the system's internal hard disk drive (HDD). Successful changes take place immediately and require a system restart. The HDD password travels with the hard drive, so the HDD is protected even when installed in another system.

Password Bypass

This option lets you bypass the system and internal HDD 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 HDD password when powered on from an off state (cold boot).

Password Change

This option lets you determine whether changes to the System and HDD passwords are permitted when an Admin password is set. Use the check box to allow or disallow 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 owner 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: Enabled

Non-Admin Setup Changes

This 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.



Performance
Option Description
Multi Core Support

Use the check box to enable / disable multi core support for the CPU.

HDD Acoustic Mode

This option allows you to optimize your HDD's performance and acoustic noise level based on your personal preferences. Settings are Bypass, Quiet, and Performance.

This field sets the of days, if any, when you would like the system to turn on automatically. The settings are Disabled, Everyday, or Weekdays.

Default setting: Off

USB Wake Support

Use the check box to enable / disable the ability for USB devices to wake the system from Standby.

This feature is only functional when the AC power adapter is connected. If the AC power adapter is removed during Standby, the BIOS will remove power from all of the USB ports to conserve battery power.
Wake on LAN/WLAN

This field allows the computer to power up from the off state when triggered by a special LAN signal or from Hibernate state when triggered by a special wireless LAN signal. Wake-up from the Standby state is unaffected by this setting and must be enabled in the operating system.

  • Disabled — Do not allow the system to power on when it receives a wake-up signal from the LAN or wireless LAN.
  • LAN Only — Allow the system to be powered on by special LAN signals.
  • WLAN Only — Allow the system to be powered on by special WLAN signals.
  • LAN or WLAN — Allow the system to be powered on by special LAN or wireless LAN signals.
