Hi all, I'm new here and completely stuck. I have a 2010 mbp which has run fine until today. I'm not very mac savvy or a heavy user and it is only now I had any data worth backing up (mainly ohto so of my baby son) so I backed up using time machine to an external hard drive. Whilst doing this I also plugged in another EHD especially to back up my iPhotos to. The back up seemed to be progressing and photos seemed to copy over to second EHD but then when I went to look on the ehd for the photos to check they had copied the whole system crashed (black screen). I tried restarting but the power switch won't turn the mbp on. I've tried every solution I can find to no avail such as trying to reset pram and SMC but not sure if any have worked or not as the thing just won't turn on. I'm off work temporarily disabled with a young baby and haven't the money for anything big to have gone wrong. Is there anything you can suggest for me to try? I'd be very grateful.
