Hi All, Just wondering if anyone with the latest 15" DL DVD Al Powerbook has had it shut down unexpectedly? I'll just be doing something (checking email, surfing web etc) and it'll just turn off... no warning, no "shutting down" message, no low battery warning, nada... just dies. I'll be able to reboot using the power button straight away (even using battery, so it's not a low battery charge problem) and it works normally again, but has to do the full reboot sequence. It's a bit spooky really... i'll be happily going along and suddenly nothing. Problem is, it'll only happen after i've had it running for a few days (i just shut the lid after i'm done with it) so it would be very hard to prove to Apple. Anyone else has had this happen? Thanks.
