Hi everyone!
I have an Elitebook 840 G1 running Windows 7 Enterprise. All the drivers are installed with the drivers off the HP site. All works fine when it's docked. However, when you power down, undock, and power back up, it hangs at the "Starting Windows" screen. We've (We meaning our Desktop group) let it sit for as long as an hour and it won't move off that screen. Then we docked it again, and it booted up fine. I have no clue what could be causing this. Any helpful suggestions would be much appreciated. Thank you in advance!
