You're completely ignoring the information before you. You're not the only one, this is exactly the reason I gave up with my original bug report.

Let me see if I can explain it any more clearly. Perhaps something is being lost in translation.

With a choice of three OSs, the only combination that does not work is when I boot *from* Kubuntu into another. The only common factor in every failing case is that I *start* in Kubuntu. How many more ways can I explain it? There is only one logical conclusion from this, and it is that Kubuntu is doing something different.

This is supported by the observable facts. When I reboot from Windows or Mandriva, my laptop does a proper restart - I see the BIOS POST screen and I get a little beep, like I do when I switch it on. When I reboot from Kubuntu, I never see the BIOS POST screen and I do not get the beep; Kubuntu goes directly from its shutdown screen to the Grub menu, and this clearly leaves the hardware in an unstable state because most of it doesn't work properly afterwards, in any OS.

Do you now accept that Kubuntu is not resetting my hardware properly when I choose 'Restart Computer'.

This only applies on my Sony laptop. My Acer laptop and my desktop reset properly. I know it could be a BIOS issue, but if it is then why does Mandriva work?
