Error 51A2: System cover has probably been opened

On my SE7320EP2, everytime I boot up it greets me with the "Error (51A2): System cover has probably been opened". The chassis intrusion switch has been totally removed and we have tried to put a jumper on the connection but we still get the error. We have cleared the event logs in the BIOS and it still comes up. Any suggestions besides changing out the motherboard?

    Turns out that one of the pins that needed to be jumpered had actually come out and didn't connect correctly, but the firmware update did fix the event log situation and helped overall. Thanks!

I would say you probably need to update the firmware. That should clear any issues you have with the event log

When switched on my pc it will display error messaga . That is "error 912 the machine cover has been removed since last system is start up"


This error is displayed if chassis intrusion protection is enabled and the cover is removed.
But as I remember you can bypass this message and start the computer. I don't remember the key, but try Escape or Enter key. (I think the button to skip this error is displayed below the message).
You can also go to BIOS and disabled Chassis intrusion detection.

The problem of my computer is when i open my computer its not boot to windows it shows chassis intruded fatal error-system halted! what can i do to solve that problem? my board is asus p5sd2-vm.


chasis intrusion is an option in the bios, when U start the pc, press dell to go into the bios, walk trhough the settings ( I think it will be in a section advanced or security) where U can switch off intrusion.

Did U open the case recently?

Chassis intrusion can be disabled one of two ways.

First, Check your bios settings. There should be a security or PC health section where you can clear that error and disable the intrusion warning.

Second, there is likely a small switch near the chassis side when the side panel is removed. This is the chassis intrusion switch. It will likely lead to a 2 or 3-pin connection on the motherboard. this can be disconected without any ill effects.

ERROR 51A2 SYSTEM COVER HAS PROBABLY BEEN OPENED - I NEED TO RESET THIS ERROR CONDITION


Go into the BIOS and disable the error message unless you are not the owner of the computer or you care when someone has opened the case.

Chassis intrusion


You need to check the chassis intrusion pin setting located on the motherboard. See page 1-30 (Number 11) in your manual.
You need to add a jumper as shown.
The system should no longer halt.

very simple shut down computer put side panel back on and restart go into bios and under the settings somewhere you will see enable chassis intrusion. Just disable that. If you put cover back on then proceeded by turning power on and you still get this error than it is time to clear CMOS and then you must go into the bios and hit setup default and then go into any timings and voltage settings for CPU Memory and such. and also disable the chassis intrusion. You can enable it at anytime. just as long it is not powered up when removing side panel. I hope this is helpful.
