Looking for ThinkPad E15 Gen 4 AMD motherboard schematic type 21ED
I have a broken e15 gen 4 AMD I want to fix or have someone fix. Doesn't power on properly just has a power light and fan spins. MOSFET PQ17 is burned out and I want to know what spec it is but I would like to have a schematic to look at or for the shop I may send it to to look at.
