Hi, I am replying to this with a bit of a delay but I was waiting for 
the laptop to be repaired. It seems that a new motherboard and an 
updated BIOS has sorted all problems including the blocked start up one. 
Having said that, before the laptop gets repaired I tried the noacpi 
parameter and indeed the problem went away. This is all very vague I am 
afraid but this is all I could observe.
