Comment 14 for bug 950282

@James,

The Beta 1 image or any current daily build should suffice. I have found that it doesn't always happen when installing, but the failure is around 75% of the time or greater.

Also, the only way I've tripped this is to have the laptop plugged in. This has only been seen on Dell equipment, but that is not to say that other machines made by different manufacturers don't have the problem, it just so happens we only have Dell equipment to try this on.
