I have upgraded memory in an Acer Veriton M464 and cannot now boot the computer as it comes up with an error message ' warning chassis has been opened'
Have tried going into bios but it will not load.  Only getting the warning message and unable to go further.

In the bios, there is an option to disable open case alert. And it will ignore its open and run normally

have you closed the case properly. there must be a sensor checking for open case. double check or just disable.

Find "Chassis Opened warning"
Set to “Disable”

That all there is too it.

Thanks for all the suggestions but the computer just sits at the black error screen.  Pressing F2 or Del will not take me to the Bios settings.  I have opened the case again and removed the cable sensor from the motherboard and have also tried removing and replacing battery.  Still getting same message.
