[CoLoCo] Dell d600 won't shut down

[Jerry Windsor]

We have about 45 Dell Latitude D600 laptops we are going to use in a mobile lab in our high school.  Many of them shutdown just fine, but we have a few that hang on splash screen on shutdown.

I have read many of the forms.  I have tried setting the grub settings to "quiet splash acpi=force" and "quiet acpi=force", and nether seem to make a difference.

We are fairly new to Ubuntu.  We are happy enough that we are in the process of making almost all of our computers dual boot, windows xp and Ubuntu.

These laptops only have an Ubuntu build, so it is important that I can get them to shutdown.

I would appreciate any input or direction that anyone wanted to offer.

Thanks in advance.
