Dell G3 3579 - keyboard not registering all keys typed

Out of the box, my new Dell G3 3579's built in keyboard has been consistently slow and not registering all the keys that I type. I first noticed this when asked to enter in a user password on system setup. Attempting to type on notepad does the same thing. It just refuses to keep up. External USB keyboards work just fine, as I'm typing on one right now.

I type around 90-100wpm and it's incredibly frustrating when this is the one aspect of the laptop that isn't working.

Below is the above sentence but typed on the laptop's keyboard:

I've dug around on this forum for help as to what it might be. I've tried changing CPU power management settings as many users suggest, and I can't downgrade the BIOS (my current version is the latest, 1.10). My main suspicion what might be the main cause of this problem is the BIOS. All of my other drivers have been up to date. It might even be a keyboard defect.

I'm interesting in hearing others' input on the issue before contacting support to possibly send in my laptop for repair/replacement.
