You might ask the laptop vendor where the intrusion detection sensor is
physically located and look there for a clue.

So what do you want US to do about it?  You didn't exactly say you know!

Assuming you don't want it there, then do what it says at the bottom of your
orig post:

1. Contact your Help Desk if you did not personally open your chassis.

If your setup password is enabled, you must know the setup password
before you can reset the Chassis Intrusion setting.  

This feature detects that the chassis was opened and alerts you to the
fact.

To change the Chassis Intrusion setting:

1. Enter system setup.
2. Press the down-arrow keys to move to the System Security option.
3. Press <Enter> to access the System Security option's pop-up menu.
4. Press the down-arrow key to move to the Chassis Intrusion setting.
5. Press the spacebar to select an option setting.
6. Exit system setup.

Option Settings:
Enabled: If the computer cover is opened, the setting changes to
Detected, and the following alert message displays during the boot
routine at the next computer start-up:

Alert! Cover was previously removed.

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

Enabled-Silent (default) — If the computer cover is opened, the setting
changes to Detected. No alert message appears during the boot sequence
at the next computer start-up.

Disabled — No intrusion monitoring occurs and no messages appear.

Hope this helps.
