A full schematic for 17IPS72 typically contains the following pages (page number assignments may vary by source):

| Page Range | Section | Critical Components/Nodes | |------------|--------------------------|--------------------------------| | 1-2 | Index & Revision History | Rev 1.0, Date 2016/10/21 | | 3-5 | Power Tree & Sequence | +3VALW, +5VALW, +1.0V_VCCIO, +1.35V_VDDQ | | 6-12 | CPU Core (VCC_CORE) | Multi-phase controller (e.g., MP2949), NCP81218 | | 13-18 | PCH (Platform Controller Hub) | RTC circuit, SLP_S3/S4#, Deep Sleep | | 19-25 | DDR4 Memory | VDDQ 1.2V, VPP 2.5V, SPD 3.3V | | 26-35 | NVIDIA GPU Core (NVVDD) | MP2888/MP2886, FBVDDQ (1.35V), PEX_VDD | | 36-40 | Thunderbolt / USB-C | TPS65982, CC lines, PD contract | | 41-45 | Audio Codec | ALC3266 (equivalent to ALC298), AMP NAU8224 | | 46-50 | LAN & Wireless | RTL8168/8111, WLAN M.2 slot (CN1) | | 51-55 | Keyboard Controller | IT8226VG, KBC_PWR_ON, AC_PRESENT | | 56-60 | DC/DC Charging | BQ24780S, ACDRV, ACP, BATDRV | | 61-65 | LCD Backlight & eDP | +LCD_VDD, eDP_HPD, Backlight PWM (BRIGHTNESS) | | 66-70 | Fan Controllers | Two fans: CPU_FAN, GPU_FAN (PWM tachometer) |

Example: Battery indicator blinks white, but Windows says “Plugged in, not charging.”
Schematic fix: Turn to the USB-C PD page. Probe:

Replace the TPS65994 and the 0.3Ω resistor (RP602) — the schematic lists its exact value. 17ips72 schematic

The 17ips72 schematic is a compact, component-dense design that balances analog front-end signal conditioning with a tightly integrated digital control section. It reads like a mixed-signal board intended for precision measurement or sensor interfacing: low-noise analog inputs, careful power-rail partitioning, and a microcontroller-driven acquisition/control domain. A full schematic for 17IPS72 typically contains the

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.

Example: +3VS5_EC -> PCH_RSMRST#.

Use the schematic’s “Net Name” cross-reference. In a PDF, search for RSMRST# — it will appear in the EC page, the PCH page, and the power sequencer page. Replace the TPS65994 and the 0

If you find a file named 17ips72_NM-D811_r1.0.pdf, verify its hash or compare page count. A typical Lenovo Compal schematic has 52 pages. Any file with fewer than 30 pages is likely incomplete or a fake.

From the schematic, create a quick test table:

| Rail | Expected Voltage | Test Point | Common Fault Component | |--------------------|----------------|--------------------------|--------------------------| | +VIN_20V | 19–20.5V | Drain of PQ101 | PF1 (fuse) | | +3VALW | 3.3V | PL101 inductor | PU101 (TPS51285) | | +5VALW | 5.0V | PL102 inductor | PC105 (short) | | VDD_CORE (CPU) | 0.8–1.3V | Phase 1 inductor (PL401) | MP86945 (powerstage) | | +VDD_GFX (GPU) | 0.7–1.0V | PL501 (near GPU) | PU501 controller | | +1.8VS | 1.8V | Test pad T13 | PC204 (capacitor) |
