How do I access my BIOS?

Resolution: You can access the BIOS by pressing CTRL+ALT+ESC as the system is booting. At the bottom of the second start up screen you should see "To enter setup, press CTRL_ALT_ESC".

Note: If the system displays the Acer Splash Screen, once you hear the beep, you should begin pressing CTRL+ALT+ESC. You may need to press CTRL+ALT+ESC continuously until you access the BIOS setup screen.

How to enable the USB Port

  • Enter the BIOS Utility Setup by pressing Ctrl+Alt+Esc during the boot-up process, but before the Operating System loads.
  • When the BIOS Utility Menu appears press F8.
  • Select Advanced Configuration.
  • Select Onboard Peripheral Configuration.
  • Ensure the USB settings are as follows:
    • USB Host Controller ------------ [Enabled ]
    • USB Legacy Mode -------------- [Disabled]
  • Press Esc three times and select Yes to save changes and exit.

Caution: Changes made in the BIOS Setup Utility influence the entire system and are made to achieve specific effects. Varying from this procedure or making additional changes is not recommended.

How can I disable the on-board LAN?

The V65LA Main Board has an on-board Intel 82558 LAN chip. There are no BIOS settings or jumpers on the Main Board to disable this function. The only way to disable this function is through the Device Manager in System Properties. To disable the on-board LAN please use the following steps:

  • Right click on My Computer and select Properties.
  • Select the Device Manager tab.
  • Click on the plus mark in front of Network adapters.
  • Right click on the drop down, Intel 82558 adapter and select properties.
  • At the bottom of the General tab, select Disable this hardware profile.
  • Close the open application windows and restart system.

Note: Do not delete the on-board LAN adapter. If the on-board LAN adapter is deleted the computer will automatically reinstall it the next time the system boots.
