I have NUC7i7bnh and I hold on long time power button, after then my NUC not turning on. To a big plus, I know how to repair boards. Please help me with my comuter, I need to work on it. It would be great if you could give me the block diagram and boardview. Thanks!
The block diagram and board view you may find in the Technical Product Specification. Could be that the Power Switch contacts are contaminated. You may try to spray over this switch with some Contact Cleaner. Wait few minutes and check if helped.
You may verify if the problem is caused by the Power Switch, by replacing it with momentary switch connected to pins 6-8 of the Front Panel Header (see 126.96.36.199 trough 188.8.131.52.4 in the Technical Product Specification).
I don't have the board schematic and I'm doubt that you may obtain it here. But instead of using the regular Power Switch, did you tried the momentary short between pins 6-8 of the Front Panel Header? If you will remove this shorted Power Switch, will be the short circuit disrupted?
