--- BEGIN OF ENTRY --- Freezes when connecting power supply or when power supply is connected. Hi guys, I have a HP Compaq mini 311c, and most of the time it works fine. But as soon I connect my power supply, the problems start. Very soon after connecting the power supply the system freezes completely, no mouse, keyboard or anything works at all. Also, when booting with power supply connected, it oftens freezes while booting (red dots stop blinking). When I click the battery icon in gnome, normally it would give you the battery percentage, but here it only says 'Estimating..'. When I click the menu item, the battery statistics window pops up, and there the percentage does show up. Any idea why this is happening, and how I can fix this? --- END OF ENTRY --- And another possibly related entry on a forum: http://programmingbulls.com/ubuntu-freezes-when-connecting-power-supply- or-when-power-supply-connected -- BEGIN OF POST --- Hi guys, I have a *HP Compaq mini 311c*, and most of the time it works fine.
