ahlia,
Start the computer and press the F2 key to enter the system bios. Once you are in the bios tab over to the Security Screen. From there locate the section that reads "Chassis Intrusion". From this section you should see the information below.
This field controls the chassis intrusion feature.
You can set this option to: Clear Intrusion Warning.
- Clear Intrusion Warning(Enabled by default if detected the chassis intrusion)
- Disable
- Enabled
- On-Silent (Enabled by default if detected the chassis intrusion)
Save the changes and exit. If this does not resolve your issue you can email me from my email address listed below in my sigfile.
Thank You,
Dell-Jesse1
