I have a Dell Optiplex Gx110 with A05 bios I'm trying to rebuild. When I start up I get and Alert! cover has been prviously removed error. I went into the cmos and disabled the detection option and also removed the battery for over 24 hrs to reset the bios. I still get the error even though it is disabled in bios. Can't get it past the error message. Please help.

Here is the info I dug up on the Intrusion Detection:

Chassis Intrusion displays the status of the system chassis intrusion monitor and can be set to Enabled, Enabled-Silent, or Disabled. The default is Enabled.

If the computer cover is removed while the intrusion monitor is set to Enabled, a Desktop Management Interface (DMI) event is generated, the setting changes to Detected, and the following message appears during the boot routine at the next system start-up:

Alert! Cover was previously removed.

If the computer cover is removed while the intrusion monitor is set to Enabled-Silent, a DMI event is generated and the setting changes to Detected, but the alert message does not appear during the boot sequence at the next system start-up.

If the intrusion monitor is set to Disabled, no intrusion monitoring occurs and no messages appear.

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

To remove the chassis intrusion switch in the low-profile chassis, perform the following steps:

Disconnect the chassis intrusion switch cable connector from the control panel on the front of the chassis.

Note the routing of the chassis intrusion cable as you remove it from the chassis. Chassis hooks may hold the cable in place inside the chassis.

Slide the chassis intrusion switch out of its slot and remove the switch and its attached cable from the chassis (see Figure 8).

Install the replacement chassis intrusion switch and cable.

To reset the chassis intrusion detector, enter System Setup during the system's POST. In the Chassis Intrusion option, press the left- or right-arrow key to select Reset, and then choose Enabled, Enabled-Silent, or Disabled (see your System User's Guide for instructions)

Go to Figure #8

My assumption would be that after you disconnect the intrusion switch that you set the BIOS to the Disabled option

by spm9928

Thanks but that was one of the first things I did. I disconnected the switch from panel and still no dice. I looked for the board jumpers as well( only jumpers were for password enable).

Just a quick comment to the previous answer...you do NOT have to remove the switch to reset it.

Just set it to Reset in the BIOS, then disable it.

by spm9928

I did this first. No luck, even when I physically detached the chasis detector from the panel.

Enter system setup (see "System Setup").

Press the down-arrow keys to move to the System Security option.

Press to access the System Security option's pop-up menu.

Press the down-arrow key to move to the Chassis Intrusion setting.

Press the spacebar to select an option setting.

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 select 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.

Entering System Setup
Turn on or restart your computer.

When Press to Enter Setup appears in the upper-right corner of the screen, press immediately.

If you wait too long and the Microsoft? Windows? logo appears, continue to wait until you see the Windows desktop, then shut down your computer and try again

I thought of that but can not get the pc to even go thru post. This error message comes imediately upon turning on the power. It never makes it to post, therefore it never looks to the a drive to boot. I understand that I have to download the update to a disk then boot with it in the drive. Can't do that under current circumstance. Thanks.

Sorry about the duplicate info. I didn't catch that there was a response already. From the way I read it, you need to set the option to RESET once, then you can set it to DISABLED.

by spm9928

That's on eof the problems. Under the security options there are only enable, enable-silent, diasable. Nothing there for the option to reset. It's driving me nuts.

by realvdude

My guess is that you have already tried this, but just in case: Have you tried setting it to enabled silent. Not that it is worth much, but the setup information states that this will change to detected when the cover is removed and generate a DMI event, but it will not show an alert during the POST startup. This may at least get you up and running.

by spm9928

I've tried all the options: enable, enable -silent, and disable and still no luck. I believe the bios must be corrupt somehow or why ele would it not reset. When I look at the bios after I reboot it show the option I've selected, but the ystem itself is acting in accordance.

Hi Steve. I just had the same problem and found that the system wasn't booting because the BIOS was looking for primary drive 1, whereas the CD-ROM drive was completely disconnected. Connecting it on the same cable as the hard drive solved it. Of course I also switch the BIOS and connections to have the CD-ROM as secondary drive 0. Anyway, I bet your computer's problem also has something to do with a discrepancy between the BIOS drive settings and the physical drive connections. Good luck if you haven't solved it yet! --Lincoln :)

I just had the same problem with the Optiplex Gx110 giving me the "strike F1 to reboot" message that would not go away and would not let me get past POST.
I changed all the settings in BIOS setup relating to the chassis intrusion including disabling it. That did not solve it. I tried everything. Then I thought about what is the last thing I did to this machine to change it from the way it was originally when it was working.
I had removed the metal hard drive chassis bay holding 2 expansion hard drives, and had disconnected them from the mainboard. When I put the metal chassis bay back into the main chassis and reconnected the drives the strike F1 message did not appear at all and the machine went right into the OS.
Thanks to the last poster who mentioned something similar and got me thinking about what the last thing I did to alter the machine.

BTW, that's one of the best trouble shooting tricks. If a machine starts having a problem just undo, one at a time each thing you recently did to the machine to change it in any way. In general think about anything you've recently done to alter the machine in any way. Even small things that don't seem like they should have any effect. Such as removing that HDD chassis bay. I've never seen any other machine be so picky about having that thing in/out, or having HDD's connected or disconnected before.

I'm glad I found this web site. Looks like it has a good community support system. I'll keep it bookmarked and try back.
