Something strange happened to me yesterday. I was travelling with my Powerbook in my Samsonite case (for the usual christmas family meeting).

When I entered the house of my parents I suddenly heard the startup sound of the Powerbook in my case. I immediately took out the computer to check what was going on. And indeed, the hd was running and the thing was booting but the screen remained dark (because the lid was closed during transport).

I shut the thing down and restarted and then it did the normal boot sequence (with screen activated).

I never had this before. I found the powerbook starting up sometimes if I left it in sleep mode. Thats why I switched off lidwake and normally don't transport the Powerbook while its asleep.

But startup without sleepmode and without pressing power is a new quality. The only drastic thing that happened was temperature and humidity change. Outside it was cold, windy and wet. Inside it was well heated with more or less dry air.

Did anyone of you had such an experience before? Its a bad feeling. Imagine the hd runs while the powerbook is transported and gets more shocks than it should with a running hd. It seems the nice power button does not work well enough. In the end we will have to remove the battery to make sure the books don't startup unintentionally.

No, never expirienced something like this (Ti 667 DVI). But i wouldnīt suggest to remove the accumulator (technically itīs not a "battery", we both know it, but certainly not some of the other readers of this thread), since (at least in my understanding) the battery which powers the PMU gets drained if the accu is removed.

But i could be wrong, itīs long since i stuck my head into technical details of my machine...

Damn, thats it.
I configured auto power on for a try because I wanted to wake up the powerbook to do some cron jobs over night when its normally asleep. Did not work as I expected and so I removed the schedule. THAT did not work. Now I trashed the preferences and the schedule is erased.
Sorry for the mess. And thank you for the right idea, cpac.
