Q: Is the LA-G851P the same as the LA-H851P? A: No. LA-G851P is the USB-C / Thunderbolt version. LA-H851P is the Legacy DC Jack only version. They are not pin-to-pin compatible. A: No

Q: Can I use the 7530 schematic for the 7730? A: 80% yes. The core logic (CPU, PCH) is identical. The 7730 has extra GPU power phases (6-phase vs 4-phase). You need the specific 7730 Boardview for component locations near the extended battery. They are not pin-to-pin compatible

Q: My schematic is blurry. Can I get a vector PDF? A: Search for LA-G851P CAD Vector file. Most scanned PDFs are raster (300dpi). Vector files are searchable and zoom infinitely. These are rare but exist.
