View Full Version : [ubuntu] Reboot After Power Failure
February 24th, 2012, 05:40 AM
I am currently running Ubuntu 11.04 as a headless server on an HP d325 CPU.
In previous versions of Ubuntu - if there was a power failure - the machine would reboot itself after the power was restored. This no longer functions in Ubuntu 11.0.4.
Does anyone know how to restore the REBOOT AFTER POWER FAILURE function?

Ubuntu (or any operating system) has no control over how to handle a power loss. Instead, you need to set this option in your BIOS Setup: what to do in case of power loss? Generally you have choices like: leave power off, power up, or previous state (if power was on when power was lost, power back up when it comes back on).
You should get a UPS (battery backup) for any server you care about. You risk a data corruption if power is lost unexpectedly; a UPS can avoid that. You can connect up the UPS to your server via USB cable so the server can tell if the battery is about to die - then the server can shut down gracefully before power is completely gone and avoid corruption problems.

Thx - I thought that would be the case but I never changed the BIOS and it worked previous to Ubuntu 11.x.
