Right, my notebook IS a 711EA (french model with a 950Mhz Duron CPU, i believe). To know which model you have, just look at at the back of your notebook !!! Perhaps dmiscan does give the info, but it seems easier to look at the ref written on the product, doesn't it ? I don't want to make you cry, but now my notebook power down alone too, and get silent when he has no activity for some minutes...sorry, but i'm so happy i can't resist to tell it ;-))) Hope the problem will get solved for you too anyway :) I'll take a look at dmiscan tomorrow morning, now it's too late for my poor eyes. little stupid question : what is the problem with disabling apic support ? I've seen it's about time CPU synchro (orsomething like that) but what is the drawback of not enabling it ? And what is the link with acpi ????
Of course, I always miss the most obvious things (bottom of laptop). Thomas,
my laptop states (on the bottom forDMI_PRODUCT_NAME) "Presario 732US
470033-480" Is this enough to go on or is DMI_BOARD_NAME also needed?
Don't worry, tu ne me fait (fais? - excuse my french) pas pleurer, my laptop
functions 99%, I just had to recompile the kernel. ;-)
right, "fais"
Je fais Tu fais Il/Elle fait Nous faisons Vous faites Ils font
Anyway, thanks for your french effort, that's always greatly appreciated to see American (you're American, aren't you ? ) knowing something about French...:-)
Regarding the link of apic and acpi. I don't know exactly why they conflict, I
think it has something to do with PCI. APIC controlls the interrupts (exactly
what that is I also don't know) for a cpu, and IIRC was designed to make
interrupts work correctly for smp computers. (that's why one disables "local"
apic). I also have no idea what the drawback of not enabling it is. It must
be something otherwise why not just drop it. BTW, I noticed that when I
wanted to disable apic i also had to disable pci hotswapping. So it seems
that that is the only thing that it is good for, in which case i can say good
riddance and I don't know why Mandrake even bothers with it. Oh well.
