Re: Need schematic for Lenovo MIIX 700 NM-A641

Thanks for the photos, but I already open up all of the shields and still no luck, small pins on ICs are fine but the balls are killing me, can't probe them!

I found out that the LDO 5V was not output from the regulator marked AWW5SE, which suppose to provide both 5V linear and 5V switched. I patched that but the board still does not turn on. Do you happen to have the schematic for 700-11isk la-d131p? I am hoping any Lenovo with 6th gen core M would be similar in design, thanks!

If someone have the schematic for this laptop/tablet Lenovo MIIX 700-12ISK with the motherboard number NM-A641 please post it, thank you so much!

It's the M7 with 8GB model, it was working but got USB power surge warning, so I took everything apart and now it doesn't turn on, all of the voltages are there except the 3 that go into the CPU. I am not sure if VR_ON is up or not because without the schematic I don't know where that trace to. The CPU power controller is ISL852, which I think mean ISL95852, it has 64 balls and the enable ball is inside so I cannot probe it. The EC is...
