FileVault Paused: any risk for the mac?

Question

Dear all,
I am not very original I will talk about FileVault that blocked in "Encryption paused" with the following text under the progress bar: "Connect power adapter to resume encryption". I have, however, a different question for which I didn't find any answer.
I got a new mac a few days ago, I did the mistake to allow FileVault during the setting up of the computer. FileVault worked fine and then stopped and stayed stuck as mentioned earlier. May be I disconnected the mac or wathever, I did paid that much of attention to it when setting up the computer to be honest.
Connection my power adapter does not change anything. I tried to reboot my mac in Recovery mode and repair my disk, it worked and I passed the different phases of the encryption; but at some point during the optimization phase it stopped again (this time I am sure I didn't disconnected it) and stay again with the text written earlier. My mac is running perfectly fine, not slow at all or whatever, and the only thing is I can see FileVault recovery is using a lot of battery when clicking on the battery.
I can no longer deactivate the encryption of the disk in disk utility while in recovery mode and I have thus to wait the end of FileVault process do deactivate it.
Should I worry about it? Is there is any risk for my computer (and may be my data) by having FileVault sticking in this mode? Risk either for the flash drive or the battery?
I have back-up of my data so I mainly worry for the hardware actually.
If not, my idea is to leave my computer like that, and hoping that it will resolve by it self at some point or with the next apple software update.
Thank you in advance for your answers.

Back up all data before proceeding. There are ways to back up a computer that isn'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 Encryption
Enter 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't turn off encryption in Disk Utility because the menu item is grayed out, you'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's instructions.
Don't erase the volume unless you have at least two complete, independent backups. One is not enough to be safe.
