Comment 7 for bug 204502

I confirm that on Dell 630, Ubuntu 8.10 and also seen in 9.04, keyboard doesn't work if I press fn+arrow(no matter up or down), and never comes back again even if I press fn+up(down) again.

Also, if I don't have power adapter plugged and bootup ubuntu, the keyboard becomes slow and cursor sticks after I login for quite a long time.
