I received my m15 R5 with 240W power adapter recently.  When I connect the power connector to charge the laptop, the connector plug (metal part) doesn't go fully inside the laptop power port.  I can still see a sliver of the metal part of the connector outside the laptop. 

I don't think the connector plug can go any further in the laptop port, so seems the connector plug length is bit too long. 

Is this normal for this laptop? or did i receive wrong power connector plug with my laptop?

Thanks!
