Re: Lenovo cg410/cg510 nm-a681 3.3v area short
Well, I would start by cleaning with caution. You have a short to the graphic card. So then you have to work with the team diagram. Review integrated and see if they are short, they are not always the problem, measure resistances according to the schematic. The unfortunate thing would be that the graphic is damaged. -

Yes, well it comes with two graphics chips one is the nvidia and the other is the integrated CPU. What you should check are the connection rails to the CPU to be discarding components. In the picture an IC is damaged, but I can not see its number. Send a better picture or the position number of the components that you see in damage!Originally posted by Sanjeewait View PostComment

Yes indeed pch is gone but i doubt the pins are not separated properly on the burnt side of ic. It appears so from the pic. If ground is in contact with other nearby pins of IC-that can be the reason of high consumption shown in bench psu. So re check once the burnt pins with schematic.Comment
