I bought it in late 2012 or early 2013 I believe. I tried repair first in early 2017 (moisture killed the SSD they all said). Then late last year I tried again.

I bought it in late 2012 or early 2013 I believe. I tried repair first in early 2017 (moisture killed the SSD they all said). Then late last year I tried again. In the meantime I have essentially used my work Mac as the only laptop. Previous company required me to leave work laptop in office that's why I bought one. Of late this company has been pressuring to install surveillance apps so my new-found interest in reviving my old laptop personal usage - browsing, mail etc - I don't anything else from my personal laptop. So essentially it has not been used since 2017 (I keep it safe in an airtight bag). It boots up and shows the [?] as in no disk found.
