My laptop hung when external power is unplug. I guess something went wrong with my wireless device, so i investigate system log for information. But unfortunately, it didnt tell anything about the case. What next do i need to do now? Im new to OpenSUSE.
About the power management setting for battery. Originally it is set to: powersave. But, even if i switch it to Performance (same mode as when on power plugged), it doesn’t helps at all. By the way, i used KDE as primary desktop manager. Any ideas?
after a whole day long trying to figure out what was wrong, i found that the problem happens with pm-utils package (pm-utils-1.4.1-5.1). So, after update this package with the newest package (pm-utils-1.4.1-19.1) from openSUSE repositories, the problem has gone.
