I have faulty Lenovo V110-15ISK with Motherboard LV115SK MB 15277-1 448.08B01.0011
There is a short 'pulse' of 3.3V and 5V, checked for short, replaced mosfets (PU4502, PU4503, PU4504, PU4505).
Checked for shorts, find only on CPU supply choke 3.3 Ohms. No shorts on chokes supplying other components.
wanted to replace controller for 3.3V and 5V (PU4501), but no marking on component.
Could anyone help me determine component, maybe got a schematics?
