Mac Mini won't turn on
I have a Mid 2011 Mac Mini (2.5Ghz i5 model A1347) which I bought from the refurb store in 2013.
From mid 2013 to late 2016 it served as a media server, running XBMC/Kodi. Towards the end of that time it started to randomly shut down. I then stopped using it and since then it's been sat in a cupboard.
I was going to wipe it and set it up for my daughter, but I can't get it started. When I try to start it, the power light comes on and I can hear something (I think it's the HDD) and then about one second later it switches off.
Any guidance on troubleshooting this would be much appreciated.
