I am currently working on a Asus u52f laptop for a customer of mine. My mind is shot and I don't have a lot of resources. I plug the power source in and push the power button, the power light comes on but nothing else does. No fan no sounds/sign of the HD, no beeps. The screen does not come up, nothing. I have tried pulling the battery and unplug the machine and hold the power button for X amount of seconds. I tried removing ram, switching, one at a time etc. I searched google for answers and just haven't gotten anything. I took the machine apart and looked at the motherboard no signs or damage(however I didn't take the motherboard completely out to check the other side) I don't want to waste to much more of my time trouble shooting this machine for I have other work to do. My best guess though is the motherboard is shot and I will have to replace it. However I don't want to go but this part replace it and have it still not work (no one does). Anyone have this problem before or has a definite solution? Thanks!
