SuSe 10.2 - System shuts down - Problem

English Install/Boot/Login
#1

I am using Suse 10.2 on AMD Turion 64 machine. Problem is, every day when I switch on machine, after about 10 minutes of usage system shuts down without giving any warning or error. Then I switch it on and it works fine whole day.

It seems this is heating problem, but I am not 100% sure. Sometimes I have seen system shutting down even when it is not heated. Also I have set system to notify me in case of excessive heating, but I never get any notification. This happens only once every day. Can someone give any hint/solution to this problem?

regards
Varun

check
/var/log
see if you can find anything there

Of course 10.2 has come to end of life, so that is not going to help you.

Thanks, I see following under /var/log/warn

From following 2 messages, does it mean it’s going to shutdown:

zmd: ShutdownManager (WARN): Preparing to sleep…
zmd: ShutdownManager (WARN): Going to sleep, waking up at 01/22/2009 11:19:29

Looks like it’s fan problem, right?

try using acpi=off in the kernel argument at boot

#5

Thanks will try that.
I have an off-topic question. Can you suggest a book on linux to get better at understanding its architecture and its capabilities, basically to get better at it (right now all I can do is learn new commands and execute them - but that does not raise my confidence in this subject).
