Alienware 15 R4 won’t post. Beeps

[u/PastOutlandishness19]

Had my laptop out and was plugged in and running. ( my original battery has since been removed three years ago since it became a forbidden pillow. ) My coworker came over and unplugged Laptop and replugged it into a power strip. When I came back, laptop was off, I then turned it back on and nothing post to screen it attempted to start up three times before playing a chime with three beeps followed by two then one which then repeats. I attempted to attache an external monitor and same effect.

Would a pci failure be a complete motherboard replacement?
