Microsoft ACPI Compliant Control Method Battery is gone!  

Have you recently upgraded your chipset drivers? you could try rolling back to the old ones. If not you could try updating the drivers

Does the installation have a system Recovery option? Many OEM installs have this option at reboot or in the Start menu somewhere.
Contact Alienware too, maybe they have some help for you even if your are out of warranty.
Look in Device Manager for the ACPI Compliant device under Batteries. If it is there it most likely will have a yellow icon beside it. Whether or not it has the icon, click its properties and uninstall it, deleting the driver (probably won't have one).
Restart and see if Windows will install it automatically.

Please post a screenshot of your Device manager open.
Also download Malware Bytes Free, update it and run a full system scan, shutdown remove power and restart, see if that helps.

I see "Uknown Device" which may be the culprit. Double click it and on the Details Tab, click Hardware ID then post a snip of that. We may be able to see if, in fact, that is the ACPI Battery.

Also you can try uninstalling it and then update drivers to see if Windows can fix it.

Have you attempted this suggestion as well?
