** Description changed: I observed this problem for the first time when I compiled and installed linux 3.2.1 on Ubuntu 11.04. This is the problem (what happens step by step): - - I reboot the computer (from Ubuntu) - - the system shuts down correctly - - the fan stops - - the fan restarts - - some seconds go by (when the manufacturer's name - the bios - should appear) - - the computer is powered off after a sharp sound (as if I used the power button) - - some seconds go by - - the computer is automatically turned on and everything goes right - - the last step doesn't happen if the supply if from the battery (the computer never turns on by itself) - - I then tried Ubuntu 11.10 and now Ubuntu 12.04 (beta 1): the problem is still the same. + - I reboot the computer (from Ubuntu) + - the system shuts down correctly + - the fan stops + - the fan restarts + - some seconds go by (when the manufacturer's name - the bios - should appear) + - the computer is powered off after a sharp sound (as if I used the power button) + - some seconds go by + - the computer is automatically turned on and everything goes right + - the last step doesn't happen if the supply if from the battery (the computer never turns on by itself) + + I then tried Ubuntu 11.10 and now Ubuntu 12.04 (beta 1): the problem is + still the same.
