Hi, For rendering purposes I often start my PC, start the rendering job and go to work. For power saving puproses I would like, that my PC "recognizes" its idle state and go down "as far as possible".
I heard of ACPI and suspend-to-RAM. I dont lik eto experiment a lot and finally find out, that it was impossible due to the start conditions and I should have known better. So I would like to know, what preconditions must be fullfilled to get that working. My system is an up-to-date Gentoo Linux system. cpuinfo says: processor : 0/1 <<- changed by me to minimize text vendor_id : AuthenticAMD cpu family : 15 model : 43 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ stepping : 1 cpu MHz : 2002.659 cache size : 512 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt lm 3dnowext 3dnow pni lahf_lm cmp_legacy ts fid vid ttp bogomips : 4010.54 lspci says: 00:00.0 Host bridge: VIA Technologies, Inc.

Finally there are 1GB Dual-Channel RAM inside. My monitor understands DPMS. My bios has APM and ACPI switches. My bootlog says beside other things about ACPI: ACPI: Core revision 20060707 tbxface-0107 [01] load_tables : ACPI Tables successfully acquired Parsing all Control Methods: Table [DSDT](id 0005) - 537 Objects with 50 Devices 140 Methods 25 Regions ACPI Namespace successfully loaded at root c0507030 Do I have a chance to successfully enable ACPI and supsend-to-RAM without hurting my hardware? Where can I get good informations about successfully activating ACPI on my PC? Thank you very much for any link/hint/help in advance ! :O) Keep hacking! mcc -- gentoo-user@gentoo.org mailing list
