Laptop : HP Compaq NC6000 Pentium M
OS : XP-SP3 .
Could not be used , not even close , timing all over the place steppers buzzing and humming ...
I turned off everything I could think of , both in the bios and in the OS , no avail , altough I did
get some improvement .
I was ready to give up and install a desktop , when I found this thread .
Changed ACPI to std PC and like magic
the system is now rock stable .
Big thanks for sharing this information , I would never have found it on my own .
