Hello. I am having some trouble with a X299 motherboard. I did some searches and I found very little info about these X299 chipset motherboards. It's a bit strange because they are known to be unreliable and I expected to find lots of posts. So I decided to make a thread and ask the experts for help 
Ok, here is the info I have.
The board is completely dead, nothing happens when I try to start it up.
I stripped it down and started measuring. I have 3.3v on the power on switch pin, so that is ok. I also found 1v on a coil near the sata ports and 3.3v on the coil next to the battery. These are all standby voltages.
I am attaching a picture with the board and the voltages.
The first problem I found is 0.3v on the vbat pin on the SIO. I checked the battery and it is ok. I also removed the battery and measured the voltage on the + tab on the socket. I also have only 0.3V there with the 24pin power plug on.
From what I read the battery is supposed to power the ICH chip, so could that be faulty? It's not that easy to reball and solder it back on (I don't have a stencil for it and manually placing balls is not fun) so I would like to be as sure as possible before I go and desolder it.
I have a pdf schematic file for an ASUS x299 board that is very similar to mine but I can't manage to find "bat" on it. I do get 28 instances but I can't see them, and adobe and chrome crashed several times while trying to scroll the file. It has too many elements I think and it just freezes. How do you guys use these pdf files?
