Dell Mini shuts down gracefully when power is unplugged

[komputes]

Dell Mini shuts down gracefully when power is unplugged. The battery is full. This started happening in recent changes in oneiric.

I find that this happens when I boot with power plugged in, but not if power is connected after booting.

@David

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the release candidate kernel versus the daily build. Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
