This could be a BIOS issue (you are running the latest available BIOS, right?) or it could just be a Windows issue...
First of all, do not pull the plug like this; this is the most damaging thing that you can do in this situation. When it gets into this state, shut it off using the power button. If a single touch doesn't work, hold it down for 4 seconds and it will always power it off completely (this is a non-maskable hardware feature in the chipset/SOC).
Hope this helps,

If the problem continues, please provide with more details of the problem. Tell me if you are getting any error message as soon as you select shutdown.
