2013 Air Running but sketchy after drop
We have new Macbook Air that was dropped on its front corner. It made a small flat spot on the edge, but otherwise it's psychically fine.
It boots and gets to a desktop and is somewhat usable much of the time. However the fan starts going full blast almost immediately and it becomes slow and unstable over time.
Also, we cannot get the machine to enter any diagnostics, reset SMC or other options at boot. Holding down any keys while booting does nothing, it just boots to the desktop and starts blowing the fan.
I was thinking a logic board, but not really sure if it could be something else. I opened it up and there is nothing obviously wrong.
Thanks for any input on this.
