Re: acer emachines e728 not working
Please try to explain your issues a little bit better like the last time with the Lenovo. History of the machine? Water damage?
Where do you probe? Pin 75 can be on any chip..
3/5v present.. Which rails? Schematic?
Measurements of all power rails..
Shorts
etc..
We can only help if you provide as much information as detailed as possible. And always try to find/attach a schematic so we don't have to search it. Many people don't want to search a schematic just for you. Keep that in my mind. We're willing to help but please explain your issues a little better
