Comment 21 for bug 114312

Diego, I'm sorry the link I've provided is unavailable. What I needed to do to get things working was installing uswsusp package and make sure the hal-system-power-hibernate-linux script runs s2disk command instead of what it runs by default. That solves the fan spin-up problem.

Restoring the original hal-system-power-hibernate-linux script results in fan not turning on after a wakeup from suspend-to-disk.

Since the original way to suspend-to-disk doesn't work properly and may result in permanent damage through system overheat if one does not notice silence from the fan I, with all respect, seriously doubt that it's wise to close this bug. Until the original Ubuntu installation can cause permanent physical damage to user's equipment, the bug should not be closed, should it?
