I have a similar issue.
My Alienware X17 R2 will not load windows if its on battery mode.
I can use the laptop fine once it is on, if I put it to sleep it wakes up fine. If I dissconnect the AC adapter will I am working the laptop does stay on for hours without any issues.
If I shut down or do a restart without the AC adapter connected and machine most times reaches the windows logon screen for a slit second and just powers off.
I have already done a clean OS install.
