Dear list, this is a little bit offtopic. I got a broken notebook as a gift (did not start, no bios screen, nothing!). Now I managed to get it running again. Everything is working, execpt the bios. The bios is broken, and the backup battery is empty in seconds.
But that is not the problem, just background info. I can start the notebook, and debian/testing is running fine. But when I want to reboot or shutdown the notebook, it does not switch off. I believe, it is a bios problem. So I tried with several kernel parameters. I tried acpi=force apm=off noacpi But none of them worked. When I tried "nolapic", then I can reboot and shutoff, but then only one cpu is available. As I do not know, where to search, I googled to get information, the meaning of acpi, nolapic and so on. "lapic" is local apic, but what is this? And can I switch completely to a software acpi, so that I am independent from the hardware? Which kernel command is the choice? Hope, someone can make this little point clearer. Best regards Hans
