Hello, here is a problem i have with a Lenovo Thinkpad E15 G2 Gen 2 MN-D011 that has no signs of life when plugged into charger. I tested it with a charged battery, laptop powers on.
Consumption on USB-C meter is 0.0A, 19.92V. I found many threads on the E15 G2, i've replaced both QB5 QB5 mosfets but no change. Does the 20V boost means that the UB7 charger ic is working ?
On QB5 i see 20V on one side and 19.74v on gate, on the other mosfet i get 20V on first side and 0.22v on gate.
Not sure where to go from here, if anyone can help.. Thanks
