Whs 2011 On Acer H340 Experience

I took the plunge and installed WHS 2011 on the Acer H340.

I used the headless install method and it worked perfectly. It installed to a fresh WD 2TB Green Drive.

The data migration from WHS v1 was time consuming but is now finished.

The only issue...

I installed Lightsout and that went fine, but the server will not sleep.

WHS says my system does not support the sleep states. Which I know it does because WHS v1 was sleeping just fine.

I investigated a little further and powercfg mentions vgapnp.sys might be the issue.

Any thoughts of how to fix this?

Thanks in advance...!!!
