Public bug reported: I'm using Ubuntu 13.04 (Kernel : 3.8.0-23-generic #34-Ubuntu) on my HP ElteBook 8470p. Ubuntu frequently freeze and I have to perform a hard reboot by holding the button more than 5 seconds. Note that this never happens when the charger is plugged, only while working on batteries. My collegues have the same laptop with the same issue.
