Hi,

I recently replaced my failed MK4004GAH 40gb HD,(sourced via ebay), with the help of guidance posted here..(Thankyou to contributors).

Everything was fine except the keyboard ribbon was not connected properly.I managed to do this whilst powered up. I popped the keyboard in place and susbsequently have had a complete failure on powering up.

Any ideas as to proceed or troubleshoot?

prior to that the rescue disks did their work, but the keyboard not working became apparent fairly quickly.

After dissamebling it all again the HardDisk connector must have worked loose, now thats in place, its all up and running.

Thanks all.. I thought about deleting this but im sure im not the only one.

maybe the power button ribbon cable needs to be reseated.
