Compaq CQ50-110US Sleep Problems

Hello,

Recently installed Suse 11.1 on a Compaq CQ50-110US laptop. Took a little doing to get sound and wireless working, but now I’m seeing a problem with sleep (suspend to RAM).

The computer seems to suspend and resume from the power state successfully but after resuming things are unstable. For instance, I often cannot unlock the computer from the screensaver after sleep. It will either not respond at all when I enter the password or say that I have to manually kill the process locking me out (which I can’t do because I’m locked out). If I use CTRL-ALT-F1 or such to go to a text login, I can enter a username but it just prompts me again and again.

I have also found the computer in a crashed state after leaving it on overnight; I assume the power management is trying to sleep the computer automatically.

I’ve seen some posts about s2ram, which I have installed, but am not sure how to try out the different options. Has anybody seen this behavior before? What can I do about this? Thanks in advance.

It’s not unusual to experience difficulty in this area and solutions are tricky at best.
You may find some help here if you haven’t see this already: HOWTOs - openSUSE

Maybe a BIOS update could help. But most Vendors do little work to improve matters for Linux.

this may not help, but it might!

if you are, instead of running the “random” screen saver pick just one
because some of them are (in my experience) not 100% perfect players…

in fact, as screen savers are not really required anymore
<http://en.wikipedia.org/wiki/Screensaver> to save the screen, why
don’t you try just turning off the screen saver, and let just the
power saver control when the screen goes to sleep…

that may be helpful (if not and you miss the pretty flashies you can
turn’em back on, but they DO take cycles and decrease your useful
battery time…

it might also be a cron that goes sour when sleeping…unless you have
changed the schedule many daily crons run after midnight-local…

next time, immediately after getting control of your machine again,
have a good look at /var/log/messages, see if you have any signs of
problems overnight…

every line begins with the form [Month] [Date] [Time]
with the time being given in the 24 hour format…i’m gonna guess you
see some problems sometime after you put your baby to sleep…
