I just got an i7 SP4 and am having an odd issue. If I have the power adapter connected to the SP4, remove it, and then try to turn the device on it will just sit at a black screen. The keyboard lights come on, but it won't wake up - I have to hold the power button for 30 seconds to reboot it. The same thing happens if the screen is off and I connect power. I've had it happen after a long wait, when it's in hibernate, and also after just a few minutes (before hibernate kicks in). If I turn the screen on prior to removing or attaching the power adapter it works fine. Has anyone else had this issue? Is there a known fix? I haven't been able to find anything online.
Issue with wake when connecting or disconnecting power.

Thanks for the replies, glad to know I'm not alone (and, as a result, that maybe Microsoft will be fixing this with an update). I have tried pressing the power button multiple times but that doesn't make a difference. I can see the lamp for the screen turn on, it just doesn't display anything unless I do a reboot. I'm wondering if it's a video driver crash. The system does play a sound, it may be the "hardware removed" sound, when this happens. I'm going to check the reliability history log like jbowden suggested and see if I have a hardware error - didn't think of that.
After checking the logs I did find an error around the time it happened. First, I received an error stating the igfx video driver stopped responding, though it supposedly recovered. Then I received an error stating an attempt to configure the input mode of a multitouch device failed (which I'm assuming is the screen). So, it appears this is a video driver crash. I know Microsoft recently released an updated firmware for i7 SP4's to fix a freeze problem due to the video driver (which I have installed)... seems they have a little more work to do on it. Hope they get it fixed.
