Cannot turn off file vault OSX Yosemite

Question

So, I started out trying to install windows via bootcamp assistant &amp; got an error when I hit partition drive. After a call to apple support this is apparently caused by filevault encryption being enabled. So I tried to disable it, it says to wait until disk is finished encrypting. Ok, fine but it also says encryption is paused because it wants a power connection, even while its plugged in at 100%. I tried a host of commands to make it start up again &amp; cleared PRAM &amp; immediately booting into recovery mode. Tried disk utility to disable encryption both in &amp; out of recovery mode. I am completely at a loss here. My diskutil cs list output looks like this:CoreStorage logical volume groups (1 found)|+-- Logical Volume Group CEF8B9F8-B04D-4A07-B867-69934AD9E7FC    &#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;    Name:         Macintosh HD    Status:       Online    Size:         499418034176 B (499.4 GB)    Free Space:   20480 B (20.5 KB)    |    +-&lt; Physical Volume E6BD0FE9-D033-4254-82F5-E8FDCC55A77B    |   ----------------------------------------------------    |   Index:    0    |   Disk:     disk0s2    |   Status:   Online    |   Size:     499418034176 B (499.4 GB)    |    +-&gt; Logical Volume Family 32B4E02D-A0D7-47D3-9787-FA97E794380A        ----------------------------------------------------------        Encryption Status:       Unlocked        Encryption Type:         AES-XTS        Conversion Status:       Converting        Conversion Direction:    forward        Has Encrypted Extents:   Yes        Fully Secure:            No        Passphrase Required:     Yes        |        +-&gt; Logical Volume 3058D72C-BBD8-4394-A45A-770B3E284429            ---------------------------------------------------            Disk:                  disk1            Status:                Online            Size (Total):          499093905408 B (499.1 GB)            Conversion Progress:   Paused            Revertible:            No            LV Name:               Macintosh HD            Volume Name:           Macintosh HD            Content Hint:          Apple_HFSAny Ideas here?

Back up all data before proceeding. There are ways to back up a computer that isn&#x27;t fully functional. Ask if you need guidance.Start up in Recovery mode. When the OS X Utilities screen appears, select Disk Utility.In the Disk Utility window, select the icon of the startup volume from the list on the left. It will be nested below another disk icon, usually with the same name. Click the Unlock button in the toolbar. When prompted, enter the login password of a user authorized to unlock the volume, or the alternate decryption key that was generated when you activated FileVault.Then, from the menu bar, select          File ▹ Turn Off EncryptionEnter the password again.You can then restart as usual, if the system is working. Decryption will be completed in the background. It may take several hours, and during that time performance will be reduced.If you can&#x27;t turn off encryption in Disk Utility because the menu item is grayed out, you&#x27;ll have to erase the volume and then restore the data from a backup. Select the Erase tab, and then select          Mac OS Extended (Journaled)from the Format menu.You can then quit to be returned to the main Recovery screen. Follow these instructions if you back up with Time Machine. If you use other backup software, follow its developer&#x27;s instructions.Don&#x27;t erase the volume unless you have at least two complete, independent backups. One is not enough to be safe.
