Acer 5742 blue light slowly on and off

[carpqueen]

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...

there are plenty of faulty m'boards on ebay, BUT WHAT IS THE PROBLEM WITH THEM?

anything specific? what will a motherboard specialist see that I won't? as you seem to know about this

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...

All the best Brett

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
