           Summary: power saving doesn't work on fujitsu-siemens c-1020
    Kernel Version: 2.6.11.5
            Status: NEW
          Severity: normal
             Owner: acpi_other at kernel-bugs.osdl.org
         Submitter: rich at hq.vsaa.lv


it's fujitsu siemens c-1020 laptop, running slackware-current
bios version - 1.35

1. echo "standby" > /sys/power/state

screen blanks, but nothing else happens.
syslog contains only :
Mar 23 10:49:59 is kernel: Stopping tasks: ========================|
Mar 23 10:49:59 is kernel: Restarting tasks... done

/var/log/acpid :

[Wed Mar 23 08:39:58 2005] received event "video VGA0 00000080 00000000"
[Wed Mar 23 08:39:58 2005] executing action "/etc/acpi/acpi_handler.sh video

2. echo "standby" > /sys/power/state

system goes to standby ok, but resuming fails. if i do this from console, it 
contains grey dots. if i do this from x, sometimes session is restored ok, i can 
move my mouse (but nothing i click on opens), sometimes it's the same garbled 
screen. if i do this from console, i can switch virtual consoles (if i do this, 
grey dots disappear) and also ctrl+l removes those dots.
after resuming hdd activity light is permanently on. after some time computer 
shuts down itself.

i can provide also output from pmtools, dmidecode or other tools, if that would 
help.
