Sounds like motherboard to me
its an Acer, and Acer motherboards are very prone to failure.
They use cheap failure-prone components, and the multilayer boards are very prone to deliminating
As a rule, they are best avoided - especially the laptops
Of the failed laptops I see, 70% or thereabouts are Acers. Ironically the older ones with single layer boards are more reliable
Repairable? Possibly if you can find someone who has an "in" with Acer can get spares from them - possibly back doored from the USA or China
