hi there, I have a power issue with an acer 5742. it can be on one moment fine, then the next it will power off, then when it's turned back on you get nothing on the screen and the blue power light slowly flashes on and off. have tested the hard drive, all good, have replaced the i5 cpu with another and the same thing. have also replaced the power board switch. any idea's? thanks

Hi :) 

Laptop repair shop for diagnosis... yes it probably the motherboard, but you need to be certain...

Hi :) 

Even by asking that question means you NEED to have it diagnosed by a Pro with the right equipment...

Hi :) 

You have read my sig,,, in my workshop, we have oscilloscopes and lots of other electronic testing equipment you have NOT got...

You don't like my advice fine, but that's all you get, I cannot spend the next week explaining all the tests we run on a lappy...

thanks for your reply brett, i wasn't looking for you to explain the finer details, just whether the problem i am getting is a motherboard one. :/  i will seek a man with an oscillyscope ;)  thanks
