                Hey, I'm trying to figure out if this is the same schematic for the board in my T480. The motherboard is labeled NM-B47 and I know the schematic above is for NM-B501. Not sure if they are similar enough or not.

                All I'm trying to do is get the correct part number for the HDMI port because this one is mangled up and needs to be replaced.

                          jtag pinout guide here from studying schematic and probing around board. the jtag is covered by silkscreen and under the WWAN card on front (side with cpu) of board jtag reset JTAG_RST pull up/pull down located near EC check silkscreen to see where. Hope this helps

                                    Can anybody help?
                                    I have this one for repair, does not charge the battery, does not bring up 20V from the charger. So i input 20v to VSYS from dc power source, now it turns on for a 15 seconds and turns off. Current consumption is 600-700mA. As i can see all power supplies are on expect GFX integrated. Also tried to inject 20V to all the 20V rails at the same time: VSYS, VINT20_IN and USBC_VBUS20 but nothing changes.

                                    Question is, should it turn on with only VSYS supplied?
