I have a Dell Precision 220 and get a message warning that the case has been previously opened (BOIS) when I start it up. How do I reset this so I know if the case has been opened again.

Thanks

The way it detects whether the case has been opened is when the circuit has been broken or not. Whenever the case is closed, you will have a complete circuit; when open, you have an open circuit. Whenenver you have your case closed again you would have reset the switch already.

This site is cool.

The message doesn't say the case 'IS' opened, it says it has been previously opened (the case is already closed again). Anyone else?

Sounds like you need some O-level calibration on that machine. Go hunt down the biggest ball-pin hammer you can find, and start whalloping things until you get some results/satisfaction. Start where you think the sensor is, and move in a spiral pattern.

Works for me, anyway.....

Seriously, you have to reset it in the bios. You have to go to the section on monitoring for case being opened and set that to ignore. Reboot once into the OS. Then reboot, going back into the bios, and then resetting it to monitor the case being open again (that is, if you want it to).

Oh, and please don't ask me how to get rid of that applet about not being shut down properly. I had to delete that from the registry to shut that off. The PC came that way.

Thank you BG-2B

Damn, the revolution never came.
