Right here go's , I have a Toshiba Satellite L450D which would not boot up in fact nothing except the green power on light, so I decided to strip it down to have a look after removing the keyboard & power switch ribbon cable & everything else I just thought I would reconnect the power cable without screwing anything back together & lo & behold the fan started to spin but only for 5 secs, the cdrom made the normal sounds I got another green light showing & the battery light came on.
But NO DISPLY never even tried to boot from the hard drive? Anyway I screwed it all back together & tried to power it up but I was back to square one nothing except again the first green light.
So I stripped it down again & attached power ribbon & I was back to lights , cd rom, fan.
I have left it at that just wondered if anyone can tell me what the fault is plz?
