I don't know what happen but my laptop vista just shut down by itself without giving me any reason. It's like someone pull of the plug. I did a search and it seemed other people complaint about problem this too. Some said it had to do with not enough power or over heated. I hope this does not happen too often or I'll be pissed off with vista.
It can't be over heated since I purchased a chill fan to cool off my laptop from the bottom. I'm not blocking the vent fan of the laptop.
The only thing I could think off which may give this problem is that recently I just add an extra USB hub (4x holes) in addition to the 4 hubs that came within my laptop which may cause that not enough power.
Anyhow, anyone had this experience with their vista?
