sorry for late reply, anyway my solution was set ACPI_SLEEP=false in /etc/default/acpi-support
that will prevent any functionality of sleep in your laptop for make it boot one time and fix the acpi-support file, just stop GRUB at start and add "noacpi acpi=off" at the kernel parameters anyway all those infos are taken from a discussion on ubuntu-users mailing list, link below: https://lists.ubuntu.com/archives/ubuntu-users/2006-October/098078.html good luck fixing your laptop! -- Repeated suspend mode after 6.10 install https://launchpad.net/bugs/75704 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
