I received an Asus U46E-BAL5 from a friend because the hinge mount on the LCD case was damaged due to the LCD screen being closed over a pen or pencil. The computer worked for a few weeks but eventually it stopped working. I advised purchasing a replacement LCD cover from ebay.com here or search. It's expensive at $175, but it's because the cover is made of aluminum. However, the hinge mounts inside the LCD are plastic and break very easily. I would suggest that additional epoxy be placed over the plastic closest to the LCD hinge mounts.
After getting the notebook computer together, it still didn't turn on, so I'm thinking something shorted the motherboard. I've ordered a replacement motherboard part here or search. At the moment, I've got the Asus U46E put back together with the replacement LCD cover, but it's not working yet. More to come as I get parts.
