thanks for reading me rrfranczak3!
your help is really appreciated
for now, i'm gonna suspend my judgement on this till i dont get the hands on the other mini i prepared for my father
i'll also try replacing the ssd
with the old one with XP loaded on and see if it charges or not!
what i have to say about your hints is:
yes one possibility is something is definetly wrong with the charging circuit or his
no, i dont think the motherboard or the ssd
died! the mini still runs ok with the remaining power in the battery...
