In order to restart I need to force shutdown and restart manually. Complete software shutdown works though.<BR /><BR />Strangely everything works just fine under Vista.<BR /><BR />Any ideas anyone?<BR /><BR />Thanks Mon, 08 Jun 2009 20:40:20 GMT svenkrause 2009-06-08T20:40:20Z https://community.hpe.com/t5/operating-system-linux/ubuntu-acpi-problems-with-hp-pavilion-t3740-de-amd-64/m-p/4435211#M36889 Using Ubuntu 9.04, ACPI doesn't work properly on my t3740.de (Mainboard is a Nodusm; see <A href="http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00714578&amp;lc=en&amp;cc=us&amp;dlc=&amp;product=3228402.)" target="_blank">http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00714578&amp;lc=en&amp;cc=us&amp;dlc=&amp;product=3228402.)</A> Basic symptom is that system doesn´t go into suspend/hybernate properly i.e. screen goes black, but power supply fan and hard disk keep running and there is no wakeup/resume.
