Comment 6 for bug 973778

I have found this problem to be intermittent. Whenever this is happening, I also get no response from pressing the power button on my computer (normally, pressing the power button gives a prompt for suspend, shut down, etc.). Also, whenever this is happening, there is no battery icon in the panel, so I cannot tell how much battery power is left. Sometimes, restarting fixes the problem, but only for a few minutes.
