Emmanuel, grazi mille. For about four years I have had this HP nc6400 running Gentoo and more recently, Ubuntu. In both, it exhbited this bug, and froze all its onboard inputs after an apparently random interval when running on battery. The kernel version you found and shared has freed it from being chained always to the power converter. It's just like a real laptop, now!
