A proper 17ips72 schematic is not a single page. It is a set of 40–60 pages, each dedicated to a functional block. Below is a breakdown of the key sections.
Symptom: Laptop boots to Windows (you hear the login sound), but LCD stays black.
Schematic use: Go to the eDP connector page (page 40). Measure: 17ips72 schematic
If +BACKLIGHT_EN is missing, trace back to the EC’s GPIO pin. A common issue: a corroded 10k pull-up resistor (PR804). A proper 17ips72 schematic is not a single page
Pages 8–12 usually cover the USB-C controller (e.g., TPS65994 or RT1715). The 17ips72 often uses ROHM’s BD99956 or TI’s TPS65987D for dual USB-C ports. If your laptop doesn’t charge via USB-C but charges via the barrel jack, suspect a failed PD controller or bad CC line resistors. If +BACKLIGHT_EN is missing, trace back to the
