Precision 5820 - Cannot disable chassi intrusion!

Hi,


I have a precision Tower 5820 and i cannot disable Chassi Intrusion detect! I would like to power on my computer without the side cover because the  air cooling inside of chassi is very bad!

I tried all ways, i tried all Bios Security Chassi Detection options and no one works...

I tried too disable the security circuit cable from the board, and if this cable is disconnect the computer doesn't power on!

I need help!!!

    When a dell tech changed one of the 2 internal fans ( in front of the bays ) in my 7820 ( it's the same chassis ) , he run the system with the lid open to make sure which of the 2 fans needed to be substituted.

    A simple screwdriver to keep the intrusion detection button pressed, was enough. There's no reason this (keeping the button pressed somehow) wouldn't work in your case ( by logic ).

    On a side note, there's no reason to cut wires or whatever. just look at the part that engages the intrusion detection, on the side cover... make something of the same dimension, fit inside the switch and keep in place using electric tape. Simple, easy, not intrusive, nothing gets damaged , and the tape peels off without leaving marks on the plastic ....

    Yes I found the same with my new 3440 and the Service manual says the first thing to do is disconnect if from the MB. I didn't find anything in the UEFI  that addressed it either.

    I tried this option! But didnt work!
    I think the metal brackets on the cover close some second circuit system...
    Then, have 2 obstacles, the security push buttom and some unknow circuit who is closed with metal brackets from side cover...

    Well, in the worst-case situation as a workaround we can tape the darn switch in the closed position. I guess we'll have to get with Tech support to actually solve this issue.

    I bought my pc on july with 3 years of pro warranty.

    I tried to change this on BIOS/SECURITY/CHASSI INTRUSION

    I tried all options, disabled, enabled and on silent. No one works. By a while of time, i could remove the side cover and use the pc without the side cover, but after some days, the system disabled this and always power off when the cover was off from computer.

    I tried to update my bios to version 2.6.1 and it is not worked...

    About the bios, the Dell launched the version 2.6.1 on 07/december and on 10/december lanched the Bios 2.5.0! The old bios is the newest??

    figure out which wires go where and jumper them and cut the switch off

    simple to do with multi meter to find out what the setting is for cover closed.

    Its either the red and black wires are open or they are shorted closed.

    The connector should stay plugged into the board.

    Cut wire a few inches from the connector and either short the cut wires together or leave them open.  This is not rocket science.
