I tried RAM, HD,Battery, Power cord, also connected an external screen in case the sound and the screen were both an issue. I am hoping to trace the power souce through the MB if I could get a service manual, as the on switch lights up.
Thanks for the quick feedback rich 912 , much appreciated.
I think you may possibly have a power board problem. If this is the case the repair is not an easy task unless you have the expertise plus the correct equipment. I recently had just such a repair carried out on one of our notebooks at a cost of £110 including collection, delivery and VAT.
The laptop was returned from workshop stating it was a MB problem & not repaired. It is owned by a lady friend of mine and as my degree is in computer science (software) it was given to me to check out. It is approximate 15months old and being of the older generation, I am reluctant to discard such a valuable piece of equipment, hench the blog.
A ‘motherboard problem’ is a very wide description of a fault. Sometimes the power board is in fact a daughter board but more usually it is part of the motherboard but can be replaced. Have a chat with the company that repaired one of my machines...
