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.

Hy guys, i have this lenovo TB-X605F with charging problem, the tablet is fake charging, i have replaced the charging connector twice, it only draws 0.40 Amps when pluging the cable for the first time then it stops drawing any Amps but the tablet keeps showing the charging image at 0% as long as i keep it connected. I have no voltage at the battery connector with the cable pluged, but i have 5 volts after usb connector on some testing points on the board.

I have Lenovo ThinkPad X1 Nano Gen 1 which is not charging on 1 usbc port (the one that has mark for charging).
When i connect usb it switchs to 20v but no current draw (only 0.02a) and orang light is on. In windows it shows that is charging but percentage is dropping.
Other usbc is charging fine,
I installed lates bios and firmwares for thunderbolt and battery.

I got a lenovo g50-80 that shows charging led (orange LED flashing) and when I press the power button the white LED comes on but the laptop doesn't switch on. The fan spins for 2 seconds when I press the power button then it stops. This problem started when my charging dock broke the connecting wires and i soldered these wires back but I might have mixed them. I ended up buying a new charging dock but laptop never switched on it just shows flashing orange LED when charger is connected. Could the super io be bad? I don't know how to go about diagnosing and I can't check any board view since this... -
I have a think pad t14 gen1, mainboardboard NM-C931 REV 1.0, I replaced the damaged USB-C charging socket, I still have a problem with charging only 5V. Where to look for the fault? Which electronic component is responsible for charging negotiation?
