I have a Dell Optiplex Gx110 with A05 bios I'm trying to rebuild. When I start up I get and Alert! cover has been prviously removed error. I went into the cmos and disabled the detection option and also removed the battery for over 24 hrs to reset the bios. I still get the error even though it is disabled in bios. Can't get it past the error message. Please help.

Here is the info I dug up on it:

Chassis Intrusion displays the status of the system chassis intrusion monitor and can be set to Enabled, Enabled-Silent, or Disabled. The default is Enabled.

If the computer cover is removed while the intrusion monitor is set to Enabled, a Desktop Management Interface (DMI) event is generated, the setting changes to Detected, and the following message appears during the boot routine at the next system start-up:

Alert! Cover was previously removed.

If the computer cover is removed while the intrusion monitor is set to Enabled-Silent, a DMI event is generated and the setting changes to Detected, but the alert message does not appear during the boot sequence at the next system start-up.

If the intrusion monitor is set to Disabled, no intrusion monitoring occurs and no messages appear.

To reset the Detected setting, enter System Setup during the system's POST. In the Chassis Intrusion option, press the left- or right-arrow key to select Reset, and then choose Enabled, Enabled-Silent, or Disabled.
