    Need schematic for Lenovo MIIX 700 NM-A641

    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 IT8586VG, also all balls.

      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!

                          For Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

                          Need help interpreting schematic of Lenovo B470 motherboard
                          by rddube
                          Hello everyone,

                          OK, so here is my issue.

                          This Lenovo B470 motherboard I am troubleshooting died and I identified it is the discrete Nvidia graphics chip that has lost it's ways!

                          So I removed it and now I am trying to change this motherboard to use UMA graphics, but I am having an issue interpreting the attached diagram. I have a 10K resistor in at the R2013 position and another one at the R2012. R2010 and R2011 are empty.

                          The motherboard starts, the fan spins but no display. It turns off by itself. I restart it and it does start but stays on...
