The is the motherboard model number for the Lenovo Legion Y720-17IKB gaming laptop. This board is based on the Intel Kaby Lake (7th Gen) platform, paired with NVIDIA Pascal-series graphics (typically GTX 1060 or 1050 Ti).

A typical switched-mode power supply (SMPS) board like the 17IPS72 features several primary circuits.

The Vestel 17IPS72 is a combination board integrating both the and the LED backlight driver onto a single printed circuit board (PCB). It is designed to work with mainboards like the Vestel 17MB120 or 17MB140.

Boosts and regulates the DC rail to roughly 400V. The is the motherboard model number for the

: Typical failures include burnt fuses, resistors, or capacitors that cause low voltage flickering or a total "no standby" condition.

A shorted Schottky diode on the 5V, 12V, or 24V rails will prevent the board from starting. "Drawing 0

This is the most common issue and almost always points to a failure in the standby power supply. You will need your multimeter and the schematic to investigate.

Power supplies store lethal amounts of energy. Always practice proper safety measures.
