Note that I experience problems with resume on this computer since circa 2.6.38; from time to time, the computer would free at resume or up to twenty seconds later with very rarely a warning and/or a bug in the log which occured around sysfs_remove_battery, as below. Today, I saved dmesg and asked for a shutdown, the computer froze during the shutdown.
