February 11, 200818 yr When I power down my unRAID server thru the webpage (Stop and then Power Down) the computer does not shut off. The fans stay running and the monitor screen screen is black. I have to manually push the power button to get it to turn off. Is this normal or anyone have a suggestion on how to fix? The motherboard is a shuttle AN35.
February 11, 200818 yr Likely a BIOS setting. Poke around in the BIOS for something under power management or APM/ACPI
February 13, 200818 yr Author I made a mistake when I do a powerdown it says system halted but the fans stay spinning. I have tried all the settings in BIOS with no luck.
February 14, 200818 yr Does the screen stay on and the last message on the screen is "System halted" ?
February 16, 200818 yr Author A BIOS update on this old motherboard (Shuttle AN35) fixed this problem.
February 16, 200818 yr When the screen stays on and the last message "System Halted" remains, that is a tell-tale sign of a BIOS problem with the ACPI interface. SOP is to disable S3 mode and allow only S1, and check for BIOS updates -- particularly one addressing ACPI or APM issues. I see a BIOS update fixed the problem.
