If you need more information from this laptop (dmidecode, ACPI AML, etc), just ask. -- Cesar Eduardo Barros cesarb@...arb.net cesar.barros@...il.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
