Lights up for a second then won't turn on - the ac power light stays on and the red light near think pad stays on. I have already tried hard reset, with and without AC adaptor along with holding power button on for 30 secs, but nothing. I left it over night on charge and it started this morning and said it had boot issues. I restarted it and tried to backup data and then it crashed with a grey screen and now not running again (same symptoms).
