Bug Description
1. Ubuntu 8.04 revison 8.04, but also true for 7.04 and 7.10
2. No idea if any particular package is involved. Happy to submit info as update if directed to a package.
3. When I HALT, I expect my laptop to remain OFF until I ask it to start again.
4. It spontaneously boots at Midnight (local time).
True Fact. I thought my battery was defective because it would not hold a charge overnight, until I happened to turn off my laptop but leave the lid open and in my view. At 00:00:08 (according to my log) the system started up, right in front of me, and without my permission. All versions of Ubuntu I have tried, including the update I ran on 5/28/2008 at approximately 04:00 GMT, show the same behavior.
This system dual boots Windows XP. One reason that OS is still present is that >AFTER< my battery runs flat, I lose control of my touchpad. The only reliable way I have found to restore function is to boot into XP. (I don't have to login, tho ;) As a point of interest, if I "halt" from XP, the system does not spontaneously start. It will not start up again until I ask it to do so.
When I halt from Ubuntu the system appears completely inert. I think there must be some kind of BIOS setting that functions as an alarm clock, although I cannot find such a setting in Windows or Ubuntu. I have learned to press and hold the power button after Halting from Ubuntu, until the fan and lights go on, and a few seconds later, off. This process does work, when I remember to follow it. Thanks, Nathan!
If anyone wants further info from the machine itself, please ask, and I will add it.
I suppose some info from the "acpi -V" command would be helpful. alternatively the contents of relevant files from /proc/acpi. I recommend putting it in a compressed file and attach it to this bugreport.
There are a couple of things that could trigger a wakeup event, those things are controlled by ACPI (or APM).
